Gas tankless water heaters are very much in demand worldwide. So if you are still one of those people with tank storage for heated water, it is now time to upgrade to a tankless system that could be considered as a great investment one can make for him. In fact, to be more specific, gas tankless water heaters are more precise than those electric water heaters because of the many factors they are supposed to have. Gas as we all know is much faster and more reliable when it comes to water heating. Mostly, people are advised to look on the buying guide if ever they need to choose those gas tankless water heaters with quality service they can provide in the households and some establishments. Here are some of the important things to remember when choosing the best tankless water heater.
Easy Installation Unit
Choose a gas tankless water heater where one can easily install or mount it on walls or external framing system. There should be brackets that come already in the unit that can help in mounting especially if it is decided to mount it on walls. The vent system also is being designed for the use of concentric stainless steel venting purposes.
BTU means British Thermal Units. This is same with calories in the metric system. It is the quantity or measurement of heat being needed to increase a pound of water by one-degree Fahrenheit. So this is one factor to be considered when choosing a specific gas tankless water heater. More capacity of having BTU means more heating power.
With high GPM (gallons per minute), this simply means the high flow rate of amount of water a gas tankless water heater can ever deliver. Activation flow rate participates a big role because of the value it will produce from a minimum flow as required to maximum flow rate required to activate the function of heating water.
Temperature Control and Lock Features
If there is a digital temperature control and more lock features in a gas tankless water heater, it easily allows one to adjust the water temperature. This also ensures the production of stable water temperature and it is made of erosion resilient material. This also allows the owner to carefully monitor the exact temperature, as it is an easy way to detect the thermostat setting as well.
Look for Energy Star
This might be the most popular factor to consider since if a gas tankless water heater is energy star certified because it contain features and benefits one person needs in a gas tankless water heater. One common feature is it has fewer worries because of savings being compared to a conventional gas tankless water heater. According to surveys, a big family will save up to $20 annually on bills of gas compared to a conventional one.
Determining the correct model
One must know the temperature of the groundwater depending on the location of the house. If the place has a colder temperature because of the present weather, then the tankless water heater needs to exert effort in order for the provision of water because it necessitates an intensification rise of temperature.
Amount of hot water needed
This mainly depends on how many fixtures available in a specific establishment. Fixtures like sinks, showers, bathtubs, etc. These typical appliances should be considered if all of them are being used at one time or not. Flow rate affects these fixtures if all of them are being used at one time because it needs less flow rate. So if someone uses a unit not so often, then a smaller unit is the right choice.
Type of venting method
Gas tankless water heaters can have two types of venting methods and these are direct vent and power vent. Direct vents are those exhaust heaters that can employ concentric apertures that can actually combine two units into one. Obviously, this could save energy, effort and time. Power vents are those heaters that take in air around to produce combustion and with the use of a single pipe for exhaust. The air to be used must be unpolluted and free of any presence of hazes.
Gas tankless water heaters main concern as well is the need for ventilation. The overall power of the tankless water heater greatly depends on the fuel source that is to be used. Gas powered units are highly recommended because of its unending supply of hot water to multiple fixtures in an establishment with the main advantage of saving money on the bills of energy being produced. Once all of the gas tankless water heaters are properly installed and as well as sized, then one is in the right track of choosing the best as tankless water heater.
