One end of my house is a long way from the water heater. It takes several minutes to get hot water to the sink or tub on that end when it’s cold outside. Has anyone installed a hot water recirculator? I’ve been looking at a Watts system online. It has a pump you install at the water heater and a valve that goes at the far end of the house that bleeds the hot water into the cold line if the temp gets too low in the hot line. Has anyone used this system? If so, how did it work and did your electric bill go up? It’s about $200 delivered on Amazon.
