Please help me to solve this puzzle. I had a Rheem gas water heater with a recirculating system for quick hot water. I never ran recirculating, as just by leaving the shutoff valves in the recirculating loop open, I started getting hot water coming out of the shower heads upstairs in about 15 seconds. (Interestingly, when I closed the shutoff valves, it took longer to get the hot water to arrive.) After 10+ years, I had to replace the old Rheem with a new Rheem bought from Home Depot. The plumber did the replacement, but now running the same way as before, it took over two and a half minutes for the water to get warm. We just couldn't figure out why.
An observation: I ran the recirculating pump, the water did get hot after a minute and a half, which is too long. Also, after recirculating a while, the piping between the pump and the heater felt warm, but that on the other side of the pump remained cold – perhaps this is an indication of the problem?
