best water heater cover and it proved itself when the electricity went out for 3 1/2 days and the water was still warm after all that time
I had it on the hot water heater for as long as I lived at the house. I don't believe it is, but the covering did make the hot water heater more efficient.
Not as is,I would take TWO blankets end to end CUT OF the extra left ,use the METALIC TAPE to secure to heater
I bought this blanket last year- easy to install, worked as advertised and large enough to fit around the water heater with overlap. Recommended
I need a water cover that is water proof
No, I would not use this for an engine compartment. Go to Summit or Jegs for heat shield type insulation.
2” is plenty of room I only had 1 1/2 on one edge and I compacted enough and even helped hold the blanket in place better
What kind of fan you need insulation for it there is bit of confusing on it. The present Denim insulation is use for heater. If you going to improve your house roofing heat, you should look for roof insulation for better heat insulation barrier.
Yes it can
