Garage Heat?

for us, we tried electric- bill to high
kerosene- stinks
propane- price to high

so,between the diesels, back-hoe, tractors, cars, and friends vehicles
we went with a waste oil burner
haven't bought any oil to run it in 4 years



120,000 btu
14 gal tank
one tank full runs 18 hours
we have 55 drums on wheels and pump to refill with

during the summer
we centrifuge our oil changes,it goes back into the diesels
others oil changes go in the storage tank, for the next winter
