Alan - Keep in mind that cheap may not be the best way to go - example - girlfriend works for a utility and a customer calls to question his
hydro bill - approx $600. - turns out the guy had put two or three $20.00 electric ceramic heaters in his garage to keep it warm during the winter - ran them day and night not knowing the meter was racing around clocking up this huge bill - do not know size of garage or insulation factor but something to keep in mind. I like kerosene heaters - you buy the fuel and can better control your costs and know your costs - with each can of fuel you buy. The heater will be more expensive up front but over all last you for years and fuel is your only expense. There are kerosene (propane also but fuel is more expensive) heaters out ther that pump out 50 to 70,000 BTU's, cost $200.00 - 400.00 Canadian and I have seen them used - the type that have a fan at the end of a cylinder where the flame burns. This circulates the heat very well and if you need to heat a double garage this WILL do it - you may even turn it off cause of the heat. Farmers use these a lot for large buildings they have and again they do work. Hopes this helps. MTS
