Tankless water heater, as the stated in the name, is the kind of water heating system that provides hot water without using a tank. Also known as instantaneous water heater, the heater heats the water on demand. When the water tap is turned on, cold water flows through the heating device and delivers hot water on the user's end.
Tankless Water Heaters works rather differently from the conventional water heating system. It does not require a tank for hot water storage and it is more environment friendly as the system avoids standby energy consumption.
There are quite a few consideration points when it comes to selecting the right tankless water heater. Power supplies, capacity, and application are some of the majors that shoppers cannot avoid. Tankless water heaters are normally powered by electrical, gas, or propane. Different power types are designed for different usage.
For example electrical tankless water heaters have lower power efficiency however it is easier to be installed. On the other hand, Gas or propane fueled tankless water heaters have better power efficient but more complex installation process.
Tankless water heaters are sized according to its maximum temperature rise possible at a given flow rate. Getting an oversized heater is a waste of money; while heaters with too low capacity will not supply sufficient hot water.
