I find that using the heat pumps, which is a very expensive piece of equipment, for the small amount of heat they provide, not worth it for heating. I have other options such as electric heaters which take the chill off just as effectively. I would rather save the heat pump/air conditioners for the summer when I don't have any other option for cooling. Hydo-Hot is one of the best sources of comfortable heat on the market today.
I purchased my rv in Buffalo, NY in February when the temperatures were in the low to mid teens. I spent the first night at a Walmart parking lot in Cleveland OH. Zone 1(front part) was only working because they had replace the rear air conditioner and didn't set the switches on the unit correctly. Even at those low temperatures and half my heating system working I was perfectly comfortable for the night and the Hydro-Hot didn't run continuously. I think it was a combination of how well the rv was insulated and how efficient the Hydo-Hot system operates.
The Hydro-Hot uses about a half gallon of diesel fuel and hour(varies with temperature) so I know it will carry me through those really cold temperatures of winter. But I try to avoid those really cold temperatures of winter!!
