We live in Michigan.
Our hot tub was delivered in August, 2015.
Since winter has arrived, this hot tub does not retain its' desired temperature.
We set the temperature to 103 degrees.
Within the first few minutes of using the hot tub, the temperature drops to 102 degrees, and it does not recover.
And, if you want to enjoy the hot tub for longer than 30 minutes?
Well, "most people don't do that" and "you must have a dirty filter" are the comments we received from the Master Spas dealer, somehow trying to justify the failure of the HL8 to retain its' desired temperature.
And of course, the California energy standards are also to blame.
Everything and everyone is to blame, except for the manufacturer.
Good thing we purchased an extended warranty ... I guess.
