MENA I think you was the one to lead me in putting the 12VDC PUMP where it is in this drawing... It was either you or PIANOTUNA that was telling me to install a low power 120VAC Electric heat elements to suppliment the propane heater core. Might be a good idea to have something to run from Battery/Inverter perhaps when off the power grid.
I did a couple of bench setups and worked pretty well. Never got to install in the trailer however...
My projects are getting further and further behind due to lack of play funds...
I got Hydronic Heat plans, SOLAR plans, Battery replacement plans, war wagon beefup plans, just to name a few. I need to start playing the lotto I think...
I got to work with one hydronic install for a fellow RV guy and it worked like a dream... Everyone is tickled pink to be able to yank out their propane heater and noisy blower fan and those them in the creek hehe...
For the smaller one room type trailer I think this is a great idea. All I know in my case is the the propane furnce is way too big for us. Runs us out of there when it comes on in the middle of the night...
Oh I also got work with another guy who ran three heat zones to different parts of his 5th wheel and had great success as well. Especially his cold floor in the bath room.
Then I ran into SMKETTNER who was using hydronic heat for his water tank heating. That was another great idea i hadn't thought about...
All good ideas...
