> Recirculate hot water-completed-pictures added
I added a system to circulate hot water. Not really a convenience thing but to use my fair weather trailer in temperatures well below freezing.
I installed an El Sid recirculating pump. This pump is good for potable water and appears to be leak proof. Fairly low amp draw on 12 volts.
I used a Grundfos valve mounted under the bathroom sink for this purpose. These are made for home systems. The vale allows hot water to return through the cold water feed back to the water heater. Valve stops the flow as temperature approaches 95F. My hot and cold pipes run together so the heat should also transfer a bit.
Here is a diagram of my water system:
The freeze up was happening under the bunks area that is not accessible.
Here is the pump:
Grundfos valve mounted against the wall:
Pump is running:
Another angle that shows the hot water pipe connection.
Also shown is my GoPower 300 watt inverter if interested.
Has worked like a charm. Only issue is I prefer not to have the pump run continuous as it makes a bit of a low rumbling noise. So I have added a small 12v relay triggered by the furnace signal wire. The more the furnace runs the more the pump runs. And of course can't hear the pump with the furnace running.
And shame on photobucket for stopping the links in a previous thread.
