Can a mini tank water heater be used with a tankless heater?

If you get that “hot water, cold water, hot water” surprise, consult a professional to see if you should combine your tankless unit with a “mini” tank water heater. The small tank water heater provides you with hot water while your tankless unit’s heat exchanger warms up.

Can a recirc turn on a tankless water heater?

Your recirc will have to move enough water to turn the heater on (probably 1/2 gpm or more) instead of moving the very tiny amount of hot water that would be necessary with a tank heater.

How do tankless water heaters conserve energy?

Point-of-use (POU) tankless water heaters are located immediately where the water is being used, so the water is almost instantly hot, which reduces water wastage. POU tankless heaters also can save more energy than centrally installed tankless water heaters, because no hot water is left in lengthy supply pipes after the flow is shut off.
