hot water recirculation?
My humble KZ 200 has a few water lines run outside of the cabin for whatever reason, in the back of the trailer, hidden under the black tank (inaccessible) My plan is to install a small hot-water r...

Finally got around to installing my hot water recirculation pump. It works very quickly, keeping all of my water lines nice and warm - no freeze danger here until I run out of propane!
The pump is simply plumbed between HOT and COLD under my kitchen sink. Intake is connected to the hot, outlet to the cold, water runs in a loop using existing plumbing through the hot water heater.
At 12v the pump is turning too fast in my opinion, it puts out more pressure than my supply pump, so it feeds hot water to the cold water faucets. This is a cheapo impeller pump, I know it's not going to last forever. An purpose made induction pump would be sweet, but boy they're expensive. I have some induction pumps from my fishkeeping days (power heads)... hmmmm maybe something can be done after my road trip.
I have created a simple controller that will regulate the pump based on the temperature of the cold water line. When the cold water line drops below 45F, the pump will start... when the line rises over 50F the pump will stop. The controller will also e-mail me if it can't raise the temperature of the water line.
I'd like to put a pressure switch inline, so when a faucet is opened, the pump will shut off.
