I have installed these in my home before with good results. Only $199 complete. Downside is 120 VAC. Since I'll be on a pedestal all winter I am considering one for freeze protection as others have said.
So how does that work?
The pump is mounted right on the hot water tank and some sort of non-electric cross-valve at the bath sink? Does it just continually leak water from the hot line to the cold or ... ?
brulaz,
Yes, I think the crossover has a setpoint of 95 degrees. The ones I installed, the pump was installed at the last fixture so no crossover valve was needed. It worked very well. On this system as you say the pump is at the WH so the crossover is needed at the last fixture. You can get extra crossovers if you have long branches off of the main run. Probably not necessary in an RV. I like the idea of the pump being at the WH because it will not take precious space in under the kitchen sink.
