Just refilled the tub. Have an older style spa pack with two speed pump. Will the tub heat faster on high or low pump settings?

Thanks in advance!

Let the spa do what it does best...

Don't try to rush and hurry a temperature change. It should heat in adequate time on low speed.

If you leave a spa running on high speed (non-digital control), you could end up with a spa sitting at 115 degrees+++ if you walk away and forget about it. Not a nice situation, and if the temp gets high enough, you could end up melting down jet fittings and major repair work to do the next day.

This spa is impressive. Heats very quickly, and I'm having success leaving on only a few hours per day to keep it up around 100+.

Thanks for the tip. Appreciate all of your info on here (solved another problem with one of your posts).
