Heat Retention While Using SPA in freezing temps

[wish2fish]

I have a DreamMaker X400.  It is a roto molded 110 volt model.

I use my spa a lot during the winter.  It sits on an elevated covered porch but has exposure from 3 sides.  When using I only expose half by flipping back half the cover.   If it is above freezing, the spa does a decent job keeping up with the cold temperatures until you approach freezing and below.  I will use the spa down to 25 degree F.   In that 25 to 32 degree range the spa will go from 100 to 98 in less than 30 minutes.  I do not use the air control when temps are this cold as it will lose heat even faster.

I'm trying to find solutions so I can get a little more time.   I like to watch basketball/football games in the spa and would like to stay in up to an hour.  As stated above, I only flip back half the cover.   I was thinking about getting a section of pool solar cover and cutting out a section where I sit.  Also considered wrapping the spa with more insulation during the winter which would also help reduced heat loss when not using the spa.

Thanks for any ideas.

This is most of your problem.  Way back in 1988, the salesman said we'd need a 220 VAC spa to keep pace with real cold temperatures, like under 40F, and we went 220.  Your issue also depends on your model's insulation, and whether you are using the jets as well.
