Underbelly Heating Ducts

[tjh@reagan.com]

Hello Everyone,

I have a 3941FL 2019. I was wondering if anyone knows if there are any heating ducts from the furnace to the underbelly (not the basement). I have thermometers in the basement, water compartment and the underbelly about mid point. With a low of 24 degrees the basement can get above 65 degrees the water compartment is good at 40 plus but the underbelly drops to about the outside temp. I opened the barrier wall to the furnace from the basement and could not see a supply to the underbelly. I called Redwood and an asked the question and they said "I think so".

Any insights would be helpful

Thanks
Tom

I don't think our 2015 rl38 has a supply duct into the basement only the return air around the stairs and dresser in the bath rm and master bed room supplies heat in the basement. your never going to keep it warm with return air so I would be fine think 40's are ok. You could put a electric cube heater in the basement off the outlet in the water service area to help out with extremes cold and windy days

My 2018 GK has two 3" flexible ducts routed from the furnace into the underbelly.

Typically the underbelly duct is a single 1 1/2” thrown in by the tanks. The 3” ones probably go to the kitchen and or living room areas registers.

There are ducts running into the basement, my compartment on 2015 MQRE stays very hot, I feequently see temps of 5 below, and never had a tank freeze, you should be fine

I haven't found any on my 2019 3901 WB. I have been wondering the same thing.
