> 3 dayI’m using the product as intended, to heat an engine compartment. My boat is 26’ and the compartment is roughly 8 x 8 x 3. The heater is well built. But my boat is not in the water and I have it at home where the hull is not insulated by the water it would sit in. Thus the heater just can’t keep up with the cold Temperatures. I had to supplement it with another heater, and even then it was on a LOT, IT sucked on the power bill. It probably would be fine for a smaller compartment like a ski boat. Or a boat in the water. UPDATE Over the winter of 2021-22 I kept the boat in the water. As I thought, the heater kept up with the cold just fine with the insulation of the water around the hull. And the electric bill was minimal.
