Works great! Slowed evaporation and the electric bill dropped $20.Thanks!!
The Thermaltech blanket works great, I noticed three distinct benefits from it:
I was able to measure the air temperature change from water to the underside of the cover and the Thermaltech blanket reduced the heat loss to the cover by 40 degrees Fahrenheit saving quite a bit on my power bill. I also noticed the circulating pump turning on less often.
The Thermaltech blanket almost completely eliminated water evaporation, I used to see steam coming out of the cover centre joint when it was cold out, but not anymore
It also lowered my chemical costs .Great product and fast shipping. I recommend this to everyone I know that has or is purchasing a hot tub
