I want to use the least amount of energy to use the solar heat for the entire day.
I have a brand new Intelliflo VS hooked up to a Zodiac iAqualink.
The solar is split into two levels, the peak of the top level is about 30 feet off of the water, while the peak of the lower level is about 20 feet off of the water.
My filter was just cleaned and is currently reading about 10psi at low pump speeds.
At 1550 RPM with the solar engaged, I don’t feel any water coming out. The Jandy AquaPure does report “Flow”, however (even after several minutes of me not feeling water going into the pool.)
At 1650 RPM with the solar engaged, I feel water moving, but you can hear some air in the system. I don’t see bubbles going into the pool, though.
At 2200 RPM with the solar engaged, I don’t hear any air.
Some questions:
1) Is it possible that at 1650 RPM that only the lower solar element is active, and the coils on the 2nd story roof are dry? If so, is there a way for me to know that the entire solar array has flowing water?
2) If the pump isn’t turning fast enough, can I destroy something in the AquaPure by running it when there’s no real flow of water? I would think that the AquaPure flow sensor would sense the lack of flow, but might this be fooled by a pump that’s kinda churning water without actually getting any real flow?
I’m also generally interested in recommended speeds when other devices are on.
For instance, when the gas heater is running, do I need to increase the pump speed so that the water doesn’t superheat?
Here’s what I currently have for speeds:
Solar Heat: 1900 (runs 9:30am to 6:30pm)
Pool: 1500 (only runs if solar panels aren’t hot enough)
Cleaner: 2850 (runs 1.5 hours twice a day) (In floor jets run off of separate single speed pump)
Pool Heat: 3000 (rarely used)
Spa Heat: 3000
Does this seem like a reasonable setup?
Is there any benefit to bumping up the pump to 3300 RPM a couple times a day to try to unstick any crud somewhere, or is that pointless?
Here's some data on RPM vs. Power for the pump.
