Eco Friendly Air Conditioning

Raj — Thu, 12 Jul 2012 03:31:23 GMT

Cooling and heating systems like air conditioning produce large amounts of greenhouse gas emissions and place considerable demand on the electricity grid.

Replace older less efficient air conditioners
By replacing older air conditioning units you could save large amounts of CO2 being released into the atmosphere each summer season. This will not only save the environment but also save you some money as well.

Some sources claim you can save as much as Nrs. 6500/- per year using a newer air conditioning unit verses an older air conditioning unit.

Choose the right size air conditioner
By choosing the proper size air conditioner for the space it will allow you to conserve energy. If you choose an air conditioner too large for the area or too small for the area then you will be causing unneeded drain on your electricity. Find a good air conditioning company where they can ensure your system is the correct size.

When looking for a new air conditioner unit you will also want to shop for one with an energy star approval on it. Check how to compare air conditioners for information on energy ratings for air conditioners.

Dehumidifiers
You will also want to look for a unit that can dehumidify the air as well if you live in a humid climate like Queensland or NT. By using an air conditioner that dehumidifies the air you will be able to make the environment more comfortable by reducing the humidity. This will allow you to keep the air conditioner at a lower setting (24 degrees celcius) and still feel comfortable.

Installation
You should have your air conditioning unit properly installed and sealed around the area to ensure you do not have cool air leaking outside. In Nepal there are different types of copper that are used in air conditioner installation. Our installers recommend using Malaysian copper that meets the standards.

Check your filters
Remember to clean and check the filters on your air conditioning unit regularly. Many air conditioners only need to be cleaned every 3 months but depending on the area you live in you may need to clean it as often as every month. This will help keep your air conditioning running more efficiently as well as keep you and your family more healthy.

Basics of air conditioner

Raj — Wed, 11 Jul 2012 16:02:57 GMT

1. What is air conditioning?

The purpose of air conditioning is to control the filtration, air movement, temperature and humidity of an atmospheric environment. Air conditioning is always associated with the cooling and dehumidification process of air and is always therefore identified with refrigeration equipment.

The full control over relative humidity by the addition of moisture by means of a humidifier and the use of a humidistat constitutes full air conditioning, but this control is not always exercised. However, the more often used partial or comfort air conditioning which uses refrigeration equipment only and is therefore capable of cooling as well as dehumidifying is still referred to as air conditioning.

From the foregoing therefore the term 'ventilation' should not be confused with air conditioning as refrigeration equipment is not necessarily provided with ventilation equipment.

2. What is relative humidity?

The atmosphere always contains moisture in the form of water vapour. The maximum amount of water vapour that may be contained in the air depends on the temperature of the air and the higher the temperature of the air, the more water vapour may be contained. At high temperatures and high moisture contents extreme discomfort is experienced as the evaporation of moisture from the body into the atmosphere by the process of perspiration becomes difficult.

In the air conditioning process the moisture content of the air may be reduced by the use of a cooling coil or added by the use of a humidifier.

The term relative humidity is simply a ratio between the actual moisture content of the air compared with the moisture content of the air required for saturation at the same temperature, ie at 100% relative humidity (also known as saturation point).

The air conditioning engineer uses the psychrometric chart to analyse how the state of moist air alters as an air conditioning process takes place.

3. Is there a difference between comfort conditioning and industrial conditioning?

Yes, the object of comfort conditioning as the name implies is solely to provide a comfortable environment for the majority of occupants. Humans are reasonably tolerant to humidity and may be comfortable from a range of between 55% and 20% relative humidity at normal comfort temperatures. It is therefore common when specifying to limit the humidity in summer and not specify a limit in winter. Typically therefore a specification would state an internal condition of 22°C / 50% relative humidity being maintained at 30°C / 20°C wet bulb external conditions in summer. In winter the specification may typically be 21°C internal temperature at -3°C saturated outside air temperature.

Industrial conditioning is provided generally for a process which requires a closely controlled atmosphere. A typical specification may be that an internal environment is required of say 21°C ±0.5°C and 50% relative humidity ±2.5% at all external conditions. It will be seen therefore that the industrial conditions for clearly defined limits rather than comfort conditioning which is based on statistical surveys of occupants feelings.

4. What is meant by a 'ton' of refrigeration?

Confusingly the unit has little to do with weight, as used in common parlance. One ton of refrigeration is the term used to refer to 12,000 B.T.U.s/hour (British Thermal Units/Hour) of cooling effect. Thus a chiller or condensing unit with a cooling capacity of 60,000 B.T.U.s/hour is said to have a capacity of 5 tons. It should be noted that the unit B.T.U./hour is a unit of heat flow still widely used in North America, Canada and parts of Asia whereas Europe uses the 'watt'. One ton of refrigeration approximates to 3.5kW of cooling.

The origin of the term is the amount of heat absorbed by one ton of ice when melting from solid to liquid state at 32°F and assuming a latent heat of ice of 144 B.T.U.s/lb. The heat absorbed is found to be 288,000 B.T.U.s over 24 hours, or 12,000 B.T.U.s/hour (in reality the latent heat of ice is slightly less than 144 B.T.U.s/lb.)

5. What is direct expansion equipment?

'Direct expansion,' 'DX,' 'refrigeration' or 'split' units are all generic terms used to identify the same equipment. The terms are in fact rather loose but in any event it has become accepted that the terms refer to two or more units, one usually positioned externally and one or more usually positioned internally. The units are connected together by site installed refrigeration pipework which is charged with a refrigerant. The external unit may take one of three forms:

a. The heat pump - which consists of a fan, compressor, coil and reversing valve, and rejects unwanted heat to atmosphere during the cooling cycle and extracts heat from the atmosphere during the heating cycle.

b. The condensing unit - which is as described above but does not have a reversing valve and therefore cools only.

c. The condenser which consists of a fan and coil (as the compressor is contained in the indoor unit); the condenser is used less often than (a) and (b).

The indoor units consist of fan coil units or air handling units which may be located in the atmosphere being air conditioned or remotely in a plantroom.

Some manufacturers produce 'external' units that may be located internally and in the case of these units ductwork is usually connected to atmosphere to reject heat or extract heat.

DX systems are in direct contrast to hydraulic systems or chilled water systems. With these systems cooling is achieved by circulating chilled water with a hydraulic pump

Generally speaking with direct expansion equipment the manufacturers match the indoor and the outdoor units and many well not sell the units individually for fear of 'mismatching' occuring.

6. What is mixed flow ventilation / air conditioning?

Mixed flow describes a method of air distribution from an air conditioning or ventilation system.

It has been and still is the most widely used method of supplying air into an atmosphere being air conditioned. This form of air distribution commonly uses ceiling diffusers or wall grilles at high level. As most air conditioning units are manufactured for the mixed flow air distribution market the associated air handling equipment has also been developed for the mixed flow market.This air handling equipment is therefore widely available and at very competitive costs as there are many manufacturers of this equipment throughout the world.

Recently displacement air distribution has gained in popularity, mainly due to comfort and cleanliness considerations. (With displacement ventilation air is introduced into the air conditioned space at low level and at low velocity). As the displacement market is still much smaller than the the size of the mixed flow market the complimentary air handling equipment has lagged behind and has generally to be made to order and is thus more expensive.

7. In view of this is it not possible to use direct expansion equipment in a low level displacement application?

When using displacement ventilation it is necessary to design the system so that the during the cooling cycle the air temperature being supplied to the space is at a higher temperature than is used for mixed flow ventilation - this is because of comfort considerations. However, if it is accepted that the air temperature adjacent to low level outlets is uncomfortably low and the layout of the space can be made to accommodate this then it may be a cost effective solution - particularly for high spaces such as large studios where it is inevitable a vertical temperature gradient arises but is of little consequence how high the air temperature is above the occupied zone. This system breaks all the rules of accepted displacement design but may be an acceptable compromise.

8. If it were possible to vary the off coil temperature during the cooling cycle of direct expansion equipment wouldn't this have the same advantage as using a chilled water system?

It is possible to vary the off coil temperature using the direct expansion equipment by the use of 'hot gas bypass' and this would make it acceptable for displacement. There are a few manufacturers that modify their equipment for 'hot gas bypass' using larger compressors, and this equipment may be applied to displacement ventilation.

9. When would a system be designed with chilled water as the cooling medium rather than direct expansion equipment?

There are several considerations:

o If the air conditioning system, no matter how small, was to be designed as a conventional displacement system then chilled water, with its inherent infinitely variable off coil temperatures, would generally be required.

o Direct expansion systems have considerably less capital costs on small to medium sized installations. However, the capital costs of both types of systems become comparitive after about a cooling load of about 1000kW. (This figure varies greatly depending on the site layout.)

o Chilled water should be used for systems where flexibility is required i.e. where partitions and room layouts are to be altered regularly.

10. What about heating?

Chilled water systems require a seperate source of heating. This would normally be in the form of a boiler and a hot water flow and return similiar to the chilled water system. It is possible to provide chilled water and hot water through the same set of pipes, (known as a manual or automatic changeover system) but these systems are more appropriate in offices when there is a clearly defined heating and cooling changeover season.

An alternative is to use electrical resistance heating although the running costs are usually prohibitively high.

Direct expansion equipment may utilize a heat pump which heats and cools through the same set of pipes.

7 Tips To Increase The Longevity Of Your Split Air Conditioner

Raj — Wed, 11 Jul 2012 15:51:31 GMT

So you have bought a split Air Conditioner to beat the heat of this scorching summer? Now remember some tips to ensure that it performs superlatively throughout its life.

The global warming has wrecked havoc on the earth as the temperature is rising and touching a new high every year. The people across the globe are suffering from the ill effects of global warming. Coupled with the scorching heat, the humidity has made life tougher than ever before. To save themselves from this unusual climatic condition, many people have fallen back on air conditioners a lot.

Whether you buy a split AC (air conditioner) or a window AC, the most important thing is to know whether they will perform smartly under tough circumstances. Since, we tend to overuse the air conditioners during the summer, we need to be prepared for their maintenance just incase they fail to perform up to the desired level. Take a look at some of the maintenance tips for split ACs that should be applied to boost the efficiency of your split air conditioner.

The smooth functioning of a product depends on its proper maintenance. So, if you have a product, then you need to take god care of it. In case of an AC whether domestic or commercial, the following points should be noted for better performance and durability of the product. The various components of it include:

1. Air conditioning filter is an important part of an AC. It should be changed every month or every two months regularly depending on its use. If not the air would be dirty and filled with pollutants. The dirty air conditioning filters also increases the air conditioning repair and maintenance cost.

2. Another important part is the compressor. It compresses low pressure, low volume gas making them the high pressure, high temperature and the gas needed for the AC. It also removes vapor from the evaporator to maintain a low boiling point. Make sure to clean the compressor regularly to get cool and refreshing air. Oil specially designed for the ACs can be used for its longevity.

3. When air passes through the system, the evaporator coil absorbs the heat to provide cold air through out the space. Replacing the old evaporator coil improves the air flow and air circulation inside the home.

4. Air conditioning maintenance also includes cleaning of air ducts or ducts. In the air conditioning system, air ducts are spread through out the entire house keeping the area cool and pleasant. Hence, the ductwork ought to be cleaned regularly to remove the dust collected on air ducts.

5. All air conditioning system use refrigerant to absorb the excess heat and supply cool air inside the house. Sometimes there might be a refrigerant leak. So, a reliable air conditioning company or contractor should be called to check and repair that part.

6. Sometimes there might be problem with the heating and split air conditioning of your air conditioner. You need to clean your air filters. If, still the problem continues, then it`s time to call an expert.

7. In some of the cases ice blocks the tube and no cold air comes from the air conditioning filter instead of the filters recently cleaned. It indicates that the air conditioning refrigerant is low and needs to be adjusted or replaced.

Although the running cost of both window and split AC is almost the same, the power consumption of a split AC could be little higher because of the additional motor it requires. Moreover, the capital expenditure of it is a bit higher than the window AC as well. A split air conditioner scores higher than a window air conditioner because of its `silence` feature. The compressor of a split air conditioner is kept away from the indoor unit and thus, ensures complete silence inside your room.

Generator Maintenance Tips

Raj — Wed, 11 Jul 2012 15:45:35 GMT

Diesel generator sets – used for either prime or backup (emergency) power – must be regularly maintained to ensure they provide quality power throughout their service life. Larger companies who own many generators, or those who rely on gensets extensively for prime power, may require an in-house engineer to maintain their gensets. Smaller companies, or users who own a generator to provide backup power in the event of an outage, may establish maintenance contracts with generator dealers and/or electrical contractors to maintain their gensets. In either instance, the life-cycle of power generators is well established and documented making routine maintenance fairly straight-forward. Best generator maintenance practice is following the maintenance schedule provided by the manufacturer of the generator.

The long outstanding use of generators over time has provided the necessary knowledge to predict when certain components will fail or be in need of service. A fairly reliable maintenance schedule can usually be acquired from the manufacturer and can be employed by a local generator dealer or other electrical contractors/engineers with experience in power generation. Adhering to this schedule will ensure maximum service time for the generator and proper operation when it is called upon to provide power. Large generator manufacturers have established maintenance plans and will not only service their own generators, but many of the other industries major brand names as well.

The main responsibilities of the maintenance contractors would be to inspect systems, study the technical data provided by the manufacturers, maintain records and take precautionary measures for safety as suggested by the manufacturers.

Some of the steps taken to ensure smooth generator operation while carrying out scheduled maintenance include:

• timely removal of worn out parts or upgrading the components

• checking fluid levels

• battery inspection and cleaning of connections

• load bank testing

• verifying control panel readings and indicators

• changing fuel and air filters.

Small investments made in replacing components and maintaining generators on a regular basis can save expensive and unnecessary upgrades or even replacement of the entire genset in the future.

When performing routine maintenance, each action taken should be logged, and the readings and various parameters are recorded along with the date of inspection and hour meter reading of the generator. These set of readings are compared with the next set of data collected. Any absurd variation of readings indicates faulty performance of the unit.

Load testing of automatic transfer switches in regular intervals keeps track of the component’s electrical and mechanical integrity in the actual mechanical transfer operation. Other factors to be checked periodically are starting and timing relays, start signal continuity, and utility phase sensing.

Preventative maintenance thus ensures that you get uninterrupted power supply for all your needs. You are assured of service on priority basis in case of dire emergency and discounted service rate for additional support or work. Once a business enters into such contracts, the facility can relax on this aspect as the maintenance provider keeps track of when the next servicing is due and makes the visits in regular intervals. They ensure that the products purchased through them receive consistent and reliable service.

Air Conditioning Tips you must know

Raj — Wed, 11 Jul 2012 15:41:55 GMT

We all like to be cool in summer and warm in winter and an air conditioner seems the perfect solution. However with rising energy concerns and more encouragement for people to be seen as ‘green’ it can be difficult to find the right balance.

Here at Service Central we’ve found a few good tips so that you can get your air conditioner operating as efficiently as possible. Saving you money and energy while your air conditioner works even better!

1. Prior to installation, find a nice shady spot, or construct a shade specifically for the air conditioner (or, in a split system, for the outdoor unit).

Air conditioners operate most efficiently while the external air temperature is cooler. By providing your air conditioner with shade from the sun you can help to lessen this temperature. It is also important to ensure there is clear, unobstructed airflow to the unit.

2. Install blinds and external shades for windows.

Heat travels easily through glass. While we close blinds and windows at night to keep the heat in, the same should be done during days in summer to keep the heat out. Close the blinds early in the morning before the sun can warm up the house and wait until it cools down outside in the evening to open them again. This will help reduce the load on the air conditioner.

3. Set the air conditioner temperature in winter to between 18-21°C and in summer to between 23-26°C.

While there can be a strong urge to have extremely cool temperatures in Summer and very warm temperatures in Winter, this is not necessary and puts an additional load on your air conditioner. Technically, during summer the humidity indoors will be lower, making it feel cooler even with a slightly warmer temperature set. For each degree you step outside of these temperatures you will consume approximately 8% more energy, adding up to a lot of money when your next bill comes.

4. With machines that have adjustable air slots, position them towards the floor when heating and towards the ceiling when cooling.

As hot air rises and cool air falls this will help to evenly distribute the air throughout the room.

5. Inspect and clean filters regularly

The amount of dust and dirt that can build up in your filters is quite phenomenal. It can lead to blocking the air and forcing your air conditioner into working harder. Cleaning the filters is usually a simple, easy procedure that can be done in a few minutes with a vacuum cleaner. We suggest you look to your unit’s manual for guidance.

6. On a hot day, try and turn the air conditioner on as early as possible

If you can turn your air conditioner on while the temperature outside is still relatively cool this will increase the efficiency of the air conditioner as there is less difference between the internal and external temperatures, making it easier for the air conditioner to reach the desired temperature and then maintain it.

7. On very humid days have the fan speed set to slow

During humid weather having your fan set to a slower speed will actually cool more effectively as the slower the air moves through the cooling equipment, the more moisture can be removed from it. You can also consider using an interior fan at the same time to help circulate the cooler air throughout the room.

8. Don’t set up televisions or lamps near the thermostat for your air conditioner

Lamps, televisions and other appliances can emit a fair amount of heat which will affect the thermostat’s reading and can lead to it misreading the room’s temperature and over-cooling the house.

9. Have your air conditioner regularly serviced

Various parts of the air conditioner can become blocked or break down, leading to less efficiency. It’s important to try and have your air conditioner serviced each year as you come into summer to ensure it’s running to its full potential. You can check for yourself to see that it is sitting level; that the seal between the air conditioner and the house is not damaged; and through passing a stiff wire through the air conditioner’s drainage pipes you can ensure that they haven’t become clogged.

We hope that with these quick air conditioning tips you can have your air conditioner running at its most efficient this year, helping you to cut down on running costs and energy usage.

Why is it important to service your Air Conditioning System?

Raj — Tue, 10 Jul 2012 17:56:15 GMT

Air Conditioning Systems are depreciated with time. And if these systems are not properly maintained and servicing timely, they progressively lose efficiency, consume more power, and waste your profits. Without regular maintenance an air conditioner looses its original efficiency steadily every passing year. It is common knowledge that these inefficiencies accelerate in the absence of adequate monitoring and maintenance.

The good news however, is that you can recover most of that lost efficiency through regular maintenance and servicing by well trained technical personnel. Studies show that with regular tune-ups a unit will maintain up to 95% of its original efficiency. This means that the cost of a periodic tune -up is recovered very quickly in savings on your monthly power bill and reduced running and repair costs

How to Cook Rice in a Microwave

Raj — Tue, 10 Jul 2012 17:48:45 GMT

1. Mix rice and water in a microwave-safe container. A good place to start is two parts water for every part of rice (e.g. 2 cups rice, 4 cups water). You can adjust the ratio through experimentation, depending on how dry or moist you prefer your rice, the power of your microwave, the size/shape of the container, etc.

Some kinds of rice may benefit from being rinsed and/or soaked before cooking. Rinsing not only cleans the rice, but it also improves texture and flavor; in Nepal, rice is fortified with vitamins that rinsing will eliminate, although those vitamins should not be necessary if you already have a well-balanced diet. Soaking simply reduces cooking time but not by much when cooking rice in a microwave.
You can add salt or butter before cooking if you wish, or cook the rice in chicken or other stock instead of water.
Make sure the container is big enough to hold the rice after it expands, as well as the boiling water: at least 4 times the combined volume of rice and water.
There are also microwavable containers specifically designed for cooking rice; see the next section for instructions.

2. Cover, place in the microwave and set the time. Here are some suggested guidelines for a 700 watt microwave and white rice:

1/2 cup rice, 9 minutes
3/4 cup rice, 12 minutes
1 cup rice, 16 minutes
1 1/4 cups rice, 20 minutes
1 1/2 cups rice, 23 minutes

For brown rice, start with three cups of boiling water per cup of rice and cook it for 25 minutes. Adjust through trial and error.

3. Let the rice sit in the microwave for five minutes after it turns off. Don't open the door. This will finish the cooking process. You might observe that the rice grains start to orient themselves vertically (like they're "saluting").[2]

4. Fluff the rice with a fork and serve.

Microwave Rice Cooker Method

Follow the instructions that come with your microwave rice cooker; these steps provide an overview of the process, assuming you have the type with two bowls and a lid.

Put dry rice in the inner bowl.
Put the inner bowl in the outer bowl and fill with water.
Cover with the lid.4
Microwave for the specified amount of time.

Tips

You don't need to cover or stir the rice during the cooking process. If you insist on covering it, though, do not seal it or the pressure will build and possibly cause the container to explode, making a big mess in your microwave.
If you are reheating rice such as chinese take-out, sprinkle a small amount of water (perhaps a teaspoon per cup of rice), onto the rice before microwaving. This helps prevent it from becoming hard again due to dehydration from the heat. Be careful not to put too much water on the rice or it may lose some of the flavor.
Alternatively, when reheating rice, you can loosely wrap or cover the rice with a damp paper towel to avoid losing the flavor.

Warnings

Do not leave rice at room temperature for longer than 1 hour. Uncooked rice can contain spores of Bacillus cereus, bacteria that can cause food poisoning. When the rice is cooked, the spores can survive. Then, if the rice is left standing at room temperature, the spores will germinate into bacteria. These bacteria will multiply and may produce toxins (poisons) that cause vomiting or diarrhea. Reheating the rice won't get rid of these toxins.
Do not take this "shortcut" when cooking sushi rice.
Make sure to use a large enough container to keep the rice from boiling over: for example, with 1/4 cup rice and 1/2 cup water, even a 1 quart container is barely sufficient.

What is VRF Air Conditioning System?

Raj — Tue, 20 Dec 2011 17:50:00 GMT

The primary function of all air-conditioning systems is to provide thermal comfort for building occupants. There is a wide range of system types available, staring with the basic window-fitted unit through to the very latest VRF (variable refrigerant flow) equipment.

Deciding which system best suits the application will depend on several variables.

For example, in a modern, design-conscious office the aesthetic requirements of the client may prove of greater importance than the number of control options they provide. While a client looking for the best life-cycle cost will need to balance capital cost with long-term operating costs, efficiency and predicted VRF systems provide cooling and heating using refrigerant (R407C or R410A) as the working fluid. There are two basic types of VRF system — cooling/heating-only and energy-recovery.

Cooling/heating-only can provide just cooling or, with the incorporation of a heat pump, cooling or heating to the space — but not both at the same time. The energy-recovery system, can provide cooling and heating simultaneously, to different parts of the building. This feature has the potential to deliver maximum energy savings. Further, a heat-recovery system can transfer the heat extracted from those spaces requiring cooling to areas demanding heating — resulting in extremely high primary-energy ratios and low operating costs.

Outdoor units are available with different cooling and heating capacities to suit the application. A host of controller options is available, from simple wireless controllers to powerful PC software packages. Finally, all the units are linked using transmission cable, providing a fully networked air-conditioning system.

VRV is a system developed and designed by Daikin Industries and means "variable refrigerant volume". Daikin protected the term VRV so other manufacturers use the term VRF "variable refrigerant flow". In principle they both work the same and are extremely efficient, reliable, energy saving ways to heat and cool all types of buildings with minimum installation time or disruption.

The volume or flow rate of refrigerant is accurately matched to the required heating or cooling loads thereby saving energy and providing more accurate control.

In short, they are probably the best systems currently available for mid to large applications.

Safety Tips for Gas Geysers

Raj — Wed, 02 Nov 2011 17:51:38 GMT

While generally safe, failures in Gas Geysers can be catastrophic. Natural gas and carbon monoxide leaks are life-threatening inhalation hazards. Overheating the water can cause scalding and even explosion hazards. Earthquakes can cause gas from you Gas Geyser to start a fire or explode. Homeowners can take routine precautions to prevent the dangers and make the Gas Geyser a safe home appliance.

Gas Leaks and Carbon Monoxide Poisoning ·
Natural gas is treated to give it a sulfur smell that is often described as similar to rotten eggs. Anytime you smell this odor in a home served by natural gas there is cause for concern. Leave the home immediately and call the gas utility company from a safe place. Refrain from using any item that may cause a spark while you are in the home, including light switches, phones or any other electrical equipment.

Another gas safety concern is carbon monoxide (CO). The combustion of natural gas results in carbon monoxide, a colorless and odorless poison. Symptoms of CO poisoning include headaches and nausea and may be misinterpreted as the flu. Any time carbon monoxide is suspected; residents should leave the home and request the home be checked by fire department officials.

Gas leaks are rare but can be prevented. Certified plumbing and heating technicians should check your Gas Geyser and associated pipes and vents annually. Both natural gas leaks and carbon monoxide poisoning can be fatal.

Hot Water Risks ·
Set the thermostat on the Gas Geyser no higher than 110 degrees Fahrenheit (43 degrees Celsius). This reduces the chance of accidental scalding. It also reduces the energy requirements of the Gas Geyser and may save the homeowner some money in the long run.

High Pressure Dangers ·
Water heated to the boiling point turns to steam and increases the pressure within the Gas Geyser. If the pressure reaches a high enough level the Gas Geyser can violently explode causing damage to the home and danger to the occupants.

There are two safety features to prevent this type of danger and both would have to fail at the same time to cause an explosion. Make sure the thermostat is operating properly. Thermostats in Gas Geysers do not allow intentional settings high enough to generate steam and pressure. Water temperatures of 120 degrees will not cause a pressure increase.

There is also a safety relief valve on every Gas Geyser. This valve will automatically vent the water in the heater when it approaches a level that is dangerous. This safety relief valve should be checked every year according to the instructions with the Gas Geyser.

Earthquake Dangers
The USA of Emergency Services lists several suggestions for Gas Geyser safety in earthquake prone areas as a way to reduce the likelihood of fires or explosions. Use straps to attach the Gas Geyser to the walls. Use three quarter inch, 24-gauge plumbers tape and 3-inch lag screws. Place one strap 9 inches below the top of the Gas Geyser and the other 4 inches above the controls. Fasten the tape to wall studs with the 3-inch lag screws. If you do not have flexible pipes connecting the Gas Geyser to the gas line, a licensed plumber can install one.
