Point of use tank vs on demand recirc
I am stuck between installing two point of use electric 1 gallon water heaters (one in master bath and one in kitchen) with the incoming water being preheated by central tank water heater OR simply installing an on demand recirculating pump. The main purpose being to eliminate the wasted water and wait time for hot water. Both the kitchen and master bath are between 20 and 30 feet from the main water heater. I plan on insulating the hot water lines regardless.
I like the simplicity of using a small point of use tank but am concerned about standby losses. I know they make tankless electric point of use but I don’t like the idea of such high demand loads.
