Alde hydronic furnace/heater-------- Has the future arrived?

This system is for SMALL Rv's. Anything over 20 feet, it will not do the job. Doug

I tolled with this concept alittle bit. I know of a couple that has done this with there smaller trailers and was amazed how well it worked.

Several on here have some things already working along this line...


My IDEA here...


Here is one install that worked great...


I know of a couple of designs using wall mounted heat registers in a couple of zones around the trailer - bath room being one...


I know of another HYDRONIC Install using tubing coils around the underbelly tanks to keep from freezing that works fine with circulating hot water.

Many of the big Diesel MOTORHOMES already use this concept with multi-heat zones...

I could setup my HOT WATER heater to do this for my OFF-ROAD POPUP for around $300 and completely do away with the propane fired furnace and very loud furnace 12VDC blower

Roy your diagrams are just plain awesome!!!

Another potential water leak source. I don't see how adding more plumbing to a vehicle that bounces and jars down the road would be wise.

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...

I think you would need another check valve in there to prevent the pump from pushing warm water to a cold faucet when opened. A system entirely separate from the potable water system would be superior and safer.

Precision Temp has had one for a bit now- not cheap, but 55k btu/hr LP input, plus dual 1500 watt elements. A bit expensive though.

beemerphile1 - you are probably correct there as well... Another good point to consider...

This thing looks good. I think many boondockers have been waiting for this.

Very interesting indeed! Thanks for sharing.
For those of you in the market for an alternative air/water heating source Truma was showing their new hydronic heaters at Overland Expo this year which can operate on propane or diesel (not both).
Cheers

PS. I picked up one of Truma's LevelCheck ultrasonic LPG measurement doohicky's… also very cool.
