Under Belly Heating

[Batman_777]

I just checked directly with Fleetwood for the 2008 Providence and it does not have heating ducts from the main furnaces to any compartments or under belly warming. The only heat underneath comes from the inside floors and walls as heat transfer. In extreme cold, open sink cabinets and washer/dryer cabinets, and don't forget cold water source to the water heater needs to be kept warm.

I looked under the coach and did not see any open plumbing.

For the water hose coming from the pedestal, I bought a higher quality drinking supply hose, heat strip and high grade pipe insulator. Place the hose and heat strip inside the pipe insulator with the heat strip on top (Don't wrap the heat tape.. stay in a straight line).

Also, don't let the heat tape touch itself since this may cause a hot spot and melt at that point.

Take tie-wraps or black duct tape (looks better than grey) and loosely wrap the three together every 5-8 inches. The heat strip, tape and pipe insulator can be found at Home Depot or Lowes.

Leave the heat strip temp sensor exposed to the outside air so it will come on when the temp reaches 35-40 degrees. The heat strip is only slightly warm to the touch.

I have heard some motorhome manufactures actually provide heat ducts to storage compartments.

The Newmar coach's have a foil duct into water tank bay and a 12v fan within the foil duct that cycles with furnace operation of Suburban.
The furnace you have may have a blocked vent opening that you may be able to add this function also.

I had a HR with a little heater in the water bay which should be the only one to worry about I know have heated bays.

I know I had to laugh when I learned that I have a bay on each side of my coach (including the plumbing bay) which is "heated" by simply allowing air flow from the bay into the coach. There's an opening under my water heater to one bay and another under my shower into the plumbing bay.
As I recall, I learned this right after my water pump froze.

i installed inside-outside temp gauges from harbor freight in the water compartments. i use 2 or 3 electric heaters most of the time inside the moho when plugged in to shore power. when using the inside electric heaters, i found that the water service compartment is the only one that needs supplementary heat when temps are below freezing. i use a drop cord light with a 100w bulb for this purpose. it is necessary to keep the water heater on, either gas or electric, or use another drop cord light. when using the propane furnace, no supplementary heat is necessary down to approx. 20 degrees. i have not seen it colder than that in my neck of the woods yet.

Heh.. my furnace is in the water bay (pump/water heater) and thus keeps it fairly warm. There is also a tee connected to the vent that runs to bathroom that feeds the tank bay.
