When comparing to other types, POUs have several advantages.

They are near 100% energy efficient.
How do I choose a point of use water heater?
Step 2: Determine the type you need
The flow rate is the amount of hot water the heater can deliver per minute. Most tankless POU heaters have a flow rate of 0.35 to 0.5 gpm, while mini-tank POU water heaters can hold 2.5 gallons. Larger tank POU heaters can hold up between 4 to 7 gallons.
Is it better to leave hot water heater on all the time?
It’s better to leave the hot water heater on all the time, rather than turning it on and off. This is a very common myth. But in fact, you really don’t need to be heating your water all the time. Your immersion heater or boiler will heat up hot water which is stored in a tank.
