We winter camp quite often with our Winnie 32h. But also had problems with the heater keeping up.
I noticed that the during the heat cycle that the burner would come on and off. I also thought that the volume of heated air was not very good. I figured that the burner was shutting off on the high limit switch.
Unfortunately we were out of warranty. So I paid to have a new blower motor and limit switches installed.
Didn't fix the problem.
So I re-evaluated the situation..
If you look in your motorhome there is only ONE return to the heater located in the bedroom against the rear wall (at least it is on my motorhome).
That return vent is the same size *only one* as all of the other outlets. To me this is a big problem.
This is how I fixed my problem.
I pulled the return grate off and looked inside and found that I could double the size of the return opening. I went to the local home store and found a bronze plate to go over the larger hole.. Expanded the return hole to the new larger size.
Now my burner doesn't cycle on and off while the t-state is calling for heat. the volume of heated air is much better. I also had a basement vent in an area that didn't need the heat.. so I closed off that vent. I also insulated the basement storage areas.
I do use an electric heater up front because of all of the heat loss from the windshield.
I have overnight-ed at below 0 temps, when it is that cold I can use 30lbs of propane in 24hrs. But I am warm.
PM me if you need to.
