Energy conservation is a worldwide concern. Studies have shown that water heating at homes consumes a lot of electricity. That why tankless water heaters have been introduced to minimize gas and electricity usage at homes. There are several advantages of using tankless water heaters for hot water needs at home apart from energy conservation. For instance, they are installed conveniently at a strategic position along the hot water line. They, therefore, take very little space compared to the traditional hot water tank. If you want to know more about these water heaters, read on.
How do tankless water heaters work?
As mentioned above, tankless water heaters are installed along the hot water line as near as possible to the hot water tap. They can be installed in showers, kitchens and other hot water points in the house. They can either electric powered or gas powered. These heaters have coils and heat exchangers that heat water as it passes through them. This means that there should be enough contact time between the water and the coils for maximum heat. That is why all tankless water heaters have a flow rate per minute. This is a measure of the amount of hot water that the heater can provide in a moment. As water flows through a tankless water heater, it recirculates, forming an endless hot water cycle that provides hot water continuously. Most regular tankless water heaters have a flow rate of 3 gallons per minute or more. The gas indoor tankless water heater is one of the highest rated tankless water heaters when it comes to the flow rate. It has a flow rate of 10 gallons per minute.
Features of tankless water heaters
There are different types of tankless water heaters and have different features and specifications. For instance, as noted above, they come in different flow rates. As you would expect, a tankless water heater with a high flow rate is more efficient that one with a lower one. Tankless water heaters also have different temperature ranges and energy saving capacities. You can easily set the desired water temperature on a certain water heater by scrolling up or down the temperature range displayed on the screen. Tankless water heaters with a wide range of temperature are more convenient for most users. However, you should consider the temperature range of a tankless water heater vis a vis its energy efficiency. If you pay exorbitant electricity and gas bills due to water heating, what will be the need of the tankless water heater in the first place?
Various models of tankless water heaters available today
There are several tankless water heaters in the market, and you can be sure there is the best one for your specific needs. When buying a tankless water heater, always consider the source of energy, the energy efficiency rating, flow rate, recirculation technology and finally the cost.
