After doing much research on heaters that may do what I indeded to use it for, this was my final choice.
Keep in mind however, this heater will heat up the area, but it will take time, it is not going to produce instant heat unless one stands right in front of it. It honestly needs time to do the job and it will. If you start with a cold room, the air as well as the walls plus other places need to heat up. Once the room heats up it gets nice and warm then and will then shut on and off all by it self.
This is in a 35 foot 5th wheel RV with 3 slideouts. It heats the whole RV when it's needed. The cost of the Propane is just to expensive to use and this is really the answer. (Keep in mind that electric is needed to operate this heater).
To really give this a jump start we also use The Big Buddy heater. Use it first and switch to this and never be cold in a room.
I took 2 whole weeks to see if this is what I hoped it was and also to see if it would fit my needs. It did and will also maybe fit your needs. I know it works in a house also as we gave it a test in a friends house. They then bought one after that.
Everyone is warm now.
