In Hawaii our electric bill is high and I found the hot water heater used the most power so I set the thermostat on the water heater down to about 130F ( they have 2, top and bottom behind a cover plate) then I ordered a blank to cover it with a R21 rating from ACE. I covered the heater top- sides and bottom with the fiber glass. The bill dropped $50 a month that is $600 a year. I had to add some scrap glass from the dump to cover ever bit of the heater. Any thing to save Money.
