Gekufa Spa and Hot Tub Bubble Insulating Cover 8ft x 8ft Thermal Solar Blanket Cover(16 Mil)

We had to change to an electric spa heater and it was taking a long time for the spa to heat up. We bought this to see if it would help. It does help, reduces the heat up time about an hour. Better than nothing. It was easy to cut to fit.

barely fits an 8 foot hot tub

Was a little bit large but works great thanks

Okay product, but very stiff even when heated. Tough to roll or fold….did not make a big difference in evaporation…….

This small thermal blanket made a huge difference in heat retention for our Jacuzzi.
