We are evaluating installing a community spa for our HOA and we are

it back down. *It will be outside in the winter and usually only used

Thanks for your input.

Well, Paul, put a cover on the thing, and make sure people use it. *It
takes *much* too long to heat a spa for every use. You want to keep it
at temp 24/7. Modern, well-insulated spas don't leak much heat except
when they're in use.

My spa has a built-in timer that you can set for periods when you want
the spa to come up to temp. I would think you'd find a similar
feature on many spas. However, for electrically heated spas, it
does take a couple of hours to increase the temp a reasonable amount,
like 20 degrees. So, it's useful if there are long periods when you
know it won't be used and have it cycle back up in advance, but as
Smitty says, useless for adjusting on a per use basis.
