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 rated 12v pump under my kitchen sink, and rig it to run intermittently, to recirc hot water back to the HWH via the cold water line.
this should serve to keep the water warm enough to avoid freezing, which happened last year at around 0F. The tubing terminates at the HWH, and at the bathroom sink, so the fittings and connections were all warm, just an ice plug developed in the outdoor pex.
What I'm wondering, perhaps those who have already done so, how long and how often to do you recirculate?
I'm planning on letting a microchip handle the menial job of timing and switching... something like an ESP8266 module, so I can adjust it via WiFi.
