This is an ENVI convection heater. It is only temporary on this piece of particle board. Once the walls are finished, I will mount it permanently on a wall. They are only a few inches deep and are mounted 6 to 8 inches above the floor on a wall. No moving parts, the way they heat is as the air inside the heater warms, it rises and draws cold air inside from the floor. Won't heat your house fast, but will maintain heat well once it is warm. Made to heat 150 sq. ft. it is perfect for my 144 sq. ft. THOW!
At about $140, it is very easy on the budget too!
