Hello,
I am new to this forum and am seeking advice.
I am planning a simple DIY solar water heater. I live in the tropics and need a system to help save our high energy costs.
I am building a collector of black polyethylene tubing and have a small recirculation pump that will run PV only and have two hot water lines running back to my small electric water heater. My plan is to hopefully hook into my conventional water heater and recirculate the heated water using the water heater tank as a storage tank.
My water heater tank appears to have three water outlets/inlets. There is the cold water in, hot water out and the outlet capped with a pressure relief valve.
I'm not sure how I can hook the recirculation lines from the collector into this tank. I was considering T ing one line into the cold water line prior to where it enters the water heater and doing the same thing for the other line into the water line at the pressure relief valve outlet. I would keep the pressure relief valve working as well. The recirc pump would bring water from the collector to the T at the cold water inlet and the return would come from the pressure relief outlet.
Does this appear workable? Do I need to install check valves anywhere or other devises?
Thanks.
Regards,
BelizeTed
