Question by : Installing a recirculating pump on a solar hot water heater?
I’m having a solar hot water system installed in my new home. The exchanger in the tank is somewhat backwards in that the tank holds the solar heated water and the domestic hot water runs through the exchanger. My question is: How is the recirculating line connected to this system? I was thinking of connecting it to the incoming cold line (with a check valve on the recirc side).

most circulating pumps are installed on the return line. I had a high limit control mounted on my supply line so as if the supply water got too hot it would shut off the boiler. I’m not sure of what’s involved in the solar system though. Hope this is helpful.
