While building our pool the pool builder offered us a deal on an in ground spa including separate pump, air blower, light, plumbing etc.
However the filter will be shared. The pool is 21000 gallons and the spa is 500 gallons. The heat pump we purchased is the Pentair Ultratemp 125000 BTU model 120, 460933. We have the Pentair variable speed pump.
We are struggling to determine whether or not this pump will be efficient enough to run the spa when temps fall into the 40's. We live in Central Texas and I just called the Pentair customer service number and they told me that once we get to the desired temperature in the spa, the heat pump will have no problem maintaining it. Is this true? And wouldn't it be using extra electricity running 24 hours a day to maintain the temp?
My apologies to those who responded to a similar post in the 'construction' forum. I just thought this forum is more appropriate.
