Hi; I'm brand new to pool ownership and this forum.
We have an in ground pool with a spa enclosure, but currently no spa or heating equipment, just a pool pump.
The pump we have is about 5 years old, and made both a lot of noise and sucked down ~13Kwh/day, 8hrs@3500RPM.
I replaced the old pump this week with a new VS pump, and both the noise and electrical use are way down. The next thing I want to do is put the spa area into operation. I'm thinking about reusing the old pump as a spa jet pump, and then adding a solar heating system to heat the spa and pool combination.
The pool is currently plumbed such that the return from the pool pump goes to both the spa area and the main pool. There is a valve that allows me to adjust how much water goes into the spa versus the rest of the pool, wide open it appears to be around 60% to the spa, and 40% to the pool, closed it goes 10% into the spa, 90% into the pool. I'm thinking that if I send the majority of the return water into the spa, and have it flow over the partition into the pool, I can get the spa hot, but also warm the pool. Any obvious problems with this approach?
