Thayden, Comfort Hot was an add on system that International Thermal Research (ITR) 800-993-4402 sold to Beavers as a supplemental 120 volt electric heat with 2 heating elements. I am not sure if it is activated by the existing room thermostat or not. I don't know what kind or year your coach is. Hope this helps, Fred
Got it.
The only thing besides the Hurricane in the loop is an electric DHW heater with a heat exchanger so that it can run on its internal electric elements or with the hurricane. The hurricane runs through it all the time. If you were plugged in, I assume the heat exchanger would work in the opposite direction so this should supply some cabin heat if the hurricane were down but you turned on the engine heat switch which runs the circulator pushing system fluid through the hurricane and DHW to the fan coil heaters.
I'm not sure if this is the comfort hot or aqua hot or neither if those are additional electric heat backups but not the DHW.
I imagine that both the set temp and theoretical BTUs of the DHW are not as high as the hurricane so you wouldn't get as much heat but maybe better than none.
Sorry this is 1998 Patriot. I put that coach info in when I signed up, but maybe it doesn't automatically show up in my public profile.
thanks
