I have an instant water heater (as backup for solar heated water) and was wondering if anyone has any experience using a hot water recirculation pump with a demand heater.
I understand that I will be circulating hot water back through the demand heater. Mine is designed to be used with preheated water, and has a modulating gas valve to turn off the flame when not needed.
I just want to hear about any other issues folks might have run into with this setup.
I do not have a return line, and have been looking into the valves that return back hot water into the cold line. Any thoughts?
Thanks and Happy Labor Day!
