Michelle was amazing to work with on the purchase of our new spa! We went with the Tuff Spa TT250 and couldn't be happier! Would recommend this local business for any of your spa needs or custom fire places.

The 5660 B model insert comes with a super quiet 110 CFM dual squirrel cage fan that pulls cool air from under the insert and blows warm air out above the insert. The Fan has a rheostat, so you can control the speed of the fan and it has a thermal sensor that will turn the fan on when the insert becomes hot and will turn itself off when the fire goes out. Just set it and forget it.
