Choosing the right Gas Geyser involves understanding your household's hot water needs. Usage varies depending on the number of people and bathrooms in your home. Selecting a suitable model depends on several factors, including hot water demand, gas availability, and water pressure.
Choose the Right Type
There are two types of gas water heaters: instant and storage type. The instant one heats the water flowing inside the heater, occupies less space than other types and can be installed in the kitchen or bathroom where the water will be used only at a certain moment.
The storage water heater stores the heated water in a tank, which allows using a big volume of it, but it requires more space for installation, and the water in the tank can be finished when there are many people who use it.
Estimate Household Demand
Consider when and where your family is using hot water. If there is only one individual showering at a time and hot water isn't required in the kitchen at the same time, a lower capacity instant unit would be sufficient. For situations where several individuals require hot water at the same time, think of getting a higher capacity unit or a storage unit.
In case of an instant heater, take into consideration the liters per minute and the heat output. In case of a storage heater, consider the tank capacity in either liters or gallons. For example, the NasGas DG-6-L Crystal 6 Liter Instant Gas Geyser is one option to compare when considering an instant model.
Check Gas Compatibility
It is important to ascertain the kind of fuel you have in your house before buying a heater. Whereas some heaters function using natural gas, others can be used with Liquefied Petroleum Gas (LPG). They are not always interchangeable, so choose a heater that matches the type of fuel available in your home.
Another aspect you need to consider is the stability of the gas supply. In case you live in an area that experiences instability in gas supply, ask the vendor whether the selected heater functions under such conditions. Never make any changes in your gas connection or equipment.
Review Safety Features
Safety should be a key part of your decision. Look for features such as flame-failure protection, overheat protection, and automatic shut-off where the manufacturer provides them.
Proper ventilation is required for gas appliances because combustion produces toxic gases, which may include carbon monoxide. It is necessary to install the heater in a spot recommended by the manufacturer. Flued gas appliances should not be installed in enclosed spaces, and the vents should not be obstructed. Seek a professional's advice to ensure that the gas lines and venting are properly done before using the appliance. In case of a gas smell, do not switch on lights or any source of fire and get out of the area.
Compare Build Quality
The construction and materials of a heater affect its durability and ability to withstand regular use. With regard to storage heaters, you should consider the material of the tank, the insulation, the burner type, and the safety valve. The insulation material should allow minimal loss of heat when water is waiting to be heated. The NasGas DG-35 Deluxe Gas Water Heater is another model to compare if you are considering a storage heater.
Check whether there is a warranty, availability of replacement parts, and service available from an authorized source. Cheap prices do not provide value if it is hard to obtain replacement parts and services. You should consider the product specifications instead of going by the looks or just a phrase like “heavy duty.”
Consider Water Pressure
Performance is related to water pressure, and this is more applicable in the case of instantaneous systems. Some heaters require a certain minimum water flow and pressure in order to start and continue working, while some come with special features to allow lower pressures.
In case there are changes in pressure within the day, you should inform this to the installer prior to buying the heater. The installer can determine whether the particular model can be installed successfully. There should not be an assumption of suitability of all low pressure products.
Plan Installation Costs
Establish a budget in which the amount is not just the cost of the unit but more than that. You might need to have suitable piping for gas, water supply, exhausts, or other changes to be made as needed. The amount will depend on your house and on the model you choose; hence, ask for an estimate beforehand.
Select a place where you can have proper access to service the appliance and ensure that children stay away from heated surfaces. Also, observe the necessary clearances.
Make the Final Choice
A good Gas Geyser should meet the requirements of your household in terms of hot water as well as compatibility with the gas supply system of your house. Analyze the available models on Electromart and decide accordingly. It will help you save some unnecessary costs as well as avoid any wrong purchase.
