Is Tiffin RED wet bay heated?

Is the underside of my 2020 Red 33AA, heated?

Id like to head to Utah, but am afraid of the 20 deg temperatures.

If the pipe bays arent heated, should I buy a small electric heater? And where do I place it?


Thanks in advance

The wet bay is heated by the rear propane furnace. When driving there is enough residual engine heat to keep the bay warm. At night you might want to put a drop light with a 100W incandescent bulb in the bay for extra heat. With temps in the 20's that should be all you need.

As previously stated your RED should have an outlet from your furnace ducting to your wet bay.

For the times the coach is parked without the furnace running I put a small 250W heater connected to a Thermo Cube that comes on at 35 and shuts off at 45 on the floor of my wet bay.

It was in the 20's last night and at 6:00 AM this morning the outside temperature was 30 and the wet bay was 52.

Nice. That is precisely what I use as well. The same Thermo Cube from Home Depot but a slightly different heater from Amazon: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1

I even put the heater on a small board as you do to keep the safety switch pushed in (because my compartment is ribbed) and to keep the heater out of any potential water.

I took my weather station outside temp sensor and put it in the rotocast wet bay. I do not have propane heat pumped in and it is about 3 degrees above the outside air temp in the 30s without the heater.

The water pump is in a different compartment which also is not heated but is foil insulated. It stays about ten degrees above the outside air temp, probably from residual heat from the fresh water tank in the same compartment.

Thank you everyone.

I found a small heater with a thermostat at Home Depot. The bay is now at a comfortable 45 deg

Since you are all electric you will have an Aquahot. There is a separate heater and temp sensor in the wet bay for the AH. All Tiffin wet bays are heated in one way or the other but in extreme cold you may need supplemental heat like the one shown above. That's what I use if the temps get down into the teens.

On our 2019 all electric Phaeton 40 AH the wet bay is heated by the Aquahot. Tiffin book says this will allow RV to be used down to zero degree weather. If RV is stored in driveway I use an electric heater inside the bus and a small ceramic heater in the wet bay. Set both heaters to 40-45 degrees and turn off Aquahot to save on diesel fuel. I use a Nimble Pet monitor in the RV and if the temps get too high or too low it sends me and my wife a warning message and an email to let us know. Purchased this monitor so our Rat Terrier would be safe if we leave him in the RV in the summertime.

For future reference you may download sales brochures from the Tiffin library.
