Hydronic and Espar Heat
Last year we modified our Winnebago View to be able to use the motorhome (full water, showers, dump tanks, without Propane) throughout the Wisconsin winters. I thought I'd share the writeup that I di...

Update:
After a few days trying different ideas and testing out our hydronic heating solution, I think I have it going in the right direction. When I first installed the 2gpm 5watt solar circulating, the pump would not keep the heat register hot enough. I then ordered a 3gpm 15watt solar circulating pump and this worked. Now the heat loss from the beginning of the loop to the end is under 8 degrees without the heat register fans on and 12 degrees with the fans on. This works.
I then installed a second heat register under the rear dinette seat. Now with both registers on and the circulating pump on, I'm getting consistent hot heat from both registers when I'm heating the hot water via shore power. Now, I need to do some testing to see how it works in much colder weather and with the Espar heating the water. Now that I have it functioning, I can do the testing.
Next, I'll wire everything into the coach thermostat and switches to control the pieces and parts.
