mermel1967 Posted November 8, 2022 Report Share Posted November 8, 2022 It was very mild here over the weekend and tub ran perfect. We're expecting a colder period and it started last night. Temperature dropped 5 degrees in the hot tub. The insulation that is with the tub is in green garbage bag material that over time has deteriorated so it is probably not doing its job. Is it advisable to use fiberglass insulation like you would use at home. Although the hot tub is in a covered area, wind does get through to the bottom. Thanks in advance... again.

In Hot Water Posted November 9, 2022 Report Share Posted November 9, 2022 75% from the top, 20% from the sides, and 5% from the bottom heat loss. Just don't choke out the pump exhaust, and you will be fine. Water logged covers loose their "R" value, so be aware of that. Other than that, "Batting" insulation is great, and the bugs and other critters love it too. (Shudder..) Quote Link to comment Share on other sites More sharing options...

CanadianSpaTech Posted November 9, 2022 Report Share Posted November 9, 2022 I would use rockwool insulation over pink. Place in garbage bag and tape it up or just pack it in there. You could also use rigid board insulation around the perimeter. 1 Quote Link to comment Share on other sites More sharing options...

Another $1,000 OUCH! get a space heater inside of it so it won't freeze before you can get it swapped out. Might be cheaper to retro fit a balboa system or a newer Gecko y series Quote Link to comment Share on other sites More sharing options...
mermel1967 Posted November 10, 2022 Author Report Share Posted November 10, 2022 @CanadianSpaTech I have a 221015 but I see models that look exactly the same but are 221063. In which way are they different? I can't use this one? Tia Cape Breton, NS And now Hr error...she's dead. Ughhh. Another $1,000 Quote Link to comment Share on other sites More sharing options...
