I have added a small expansion tank , a check valve and a recirculation pump.
I did a loop back return with Insulated ½ pex on my hot water line.

I added insteon home automation switches in the bathrooms and at the kitchen sink.
When you turn on the bathroom light I kick off the recirculation pump for a set amount of time. It depends how far the bath is from the tank as how long I run the pump. It either times out say for 2 min or when you shut off the switch it will also turn off the recirculation pump. I will also set it to run before the boys go to school because that is a set time each day.

I really like this setup I am not wasting natural gas by running recirculation pump all the time but I don’t have to waste water and wait a long time for hot water.


The only thing I have left to do is add in the aquastat and experiment with my inverter for when power goes out.
