Heating - how much time does it take to heat fifth wheel?

Open the area behind your heater and see how the flex duct looks. Mine was a jumbled mess. I was able to trim off an average of 6' on each line and straighten them out. Much better air flow now.

There's not really enough data to answer the question. Those owning the same RV can likely answer better but it totally depends on outside temp, inside air temp, AND how long it's been at 32degrees (+coach construction, etc.). If you've left it long enough it's going to take at least an hour to warm up the entire interior (different from just air temp) to the point that the heater doesn't continuously cycle from the entire RV being cold soaked.

I think SCVJeff raises a couple good points here. Keep in mind that it's not just about heating the air inside the RV, but how long it takes for RV itself to absorb heat energy from the newly-warmed air. I would be curious as to how long it would take for a 0* RV to reach room temperature if pulled into a consistently room temperature garage or shop bay. That answer has more to do with the materials' ability to absorb heat, and less to do with the capability of the furnace.

Thanks djgarcia. My fifth wheel is taking much longer....more like minimum 5 hours! Just wanting to see what others experience is.

I would suggest that you take the trailer to a "trusted RV repair shop" not your dealer and have them check out your complete heater system and the thermostat.

It's common practice when testing air conditioning to monitor the air temp at the vent to get an idea of performance. I imagine it would be the same with heating, vent temp should be XX* which would have almost nothing to do with how cold the camper is (once the ducting heats up). 5 hours just doesn't sound reasonable.

30 to 60 minutes would be my estimate. While I have camped well below freezing I have never cold soaked the trailer and timed the furnace.

Does your burner cycle as it is heating? Because it should not.
Mine used to take forever because the poorly installed ducting. I added two more ducts and we get so much more heat it is just amazing.

Funny Art. Thanks for your replies everyone. My trailer has the Polar Pkg as well go figure....maybe too much heat going to uderbelly...what do I know I just want it to be warm a lot faster then 5 hrs and running non stop. This can't be "normal".

Ours is a lite, thin walled 5'er, 30' long with 2 slides. We never RV in subzero weather but have many times around 25ish. Heats up quick, maybe 15 minutes. Bedroom takes longer as the floor vent doesn't blow much air at all. Am told this is by design as the bedroom doesn't need much. Can't sleep if its very warm so it works for us.

The RV should be comfortable in thirty minutes to an hour. The mattress on the bed --- probably not before tomorrow morning :D
