Bill -
I do not understand what that would do.

The box stores sell hot water circulating pumps. All connections can be made
under the sink. The pump draws from the hot and pumps it back into the cold.
Your application under the sink will depend on what you have.

The pumps can be run off of a t-stat on the hot water line or by time.

Changing over to gas creates some ventilation issues. Better check your
local code.

I was looking at a demand water heater yesterday, it took TWO 50 amp 2 pole
circuits.
Ya like I am going to install one of those.
