Replacement Propane Furnace

[markoch]

I installed the Truma Combi in my Simplicity SRT and have been very happy with the nearly silent performance. I also had a Cat brand vented catalytic heater in my boat and that was a quiet, clean, safe solution. Both are expensive. The cat can be found at http://www.ventedcatheater.com/. Installing the Truma required completing a bunch of tasks to tap into the propane, plumbing, power, and ducting. It fit where I removed the Suburban furnace and water heater with space to spare.

Recently installed Espar D2L diesel heater. Very very efficient, the sound is there but more even and not distracting. And very warm! The old constant cycling is gone!

Hi,
Here is one Atwood that uses a 2 stage burner -- I assume its quieter on the lower stage?
Excalibur XT 2-Stage RV Furnace with Thermostat

Way to big for a class B at 34,000 btu/hr. Uses a lot of power, also, 11 amps on high and 5 on low.

I second Espar Airtronics D2, best RV heater I ever had but it is diesel powered. Propex is also very quiet and powered by LPG.

Agreed. That thing would toast you in Siberia. High at 16,000 BTU and low at 8,000 with a digital thermostat with one degree hysterisis would do it.

Certainly a correct idea needed on a smaller scale for Class B.

I re-emphasize the heated mattress pads. Try it, you will like it.

Here’s a clarification. The furnaces don’t make the condensation inside our vans, we do. Any condensation from the burning of whatever fuel it uses, propane, diesel or gasoline goes out the exhaust along with any carbon monoxide as long as it’s working properly. The moisture inside the van is primarily from us breathing and perspiring (more than 3 cups a day per person), but also from cooking and bathing. The condensation is just a factor of that moisture contacting a cold surface.
Sorry, I was a home inspector for more than 25 years and saying things inaccurately was a good way to get sued.

An earlier post asked about using a catalytic propane heater and those do release water vapor.
