Swimming Pool Solar Heating System (Alta Vista)

This system includes panels that had been installed on my house roof in 2008 at total cost of $6,600 and used for 20’x40’ in-ground pool up until August 20th, 2022. Electronic controls were housed in a pool shed.
The system heated water up to 120 degrees Fahrenheit (temperature of water coming from panels).

See enersol.com for general info, FAQ, and installation instructions.

Extend your swimming pool season this year and start up early next year! The heating is free.

It Includes:
- 30 rubber 12” x 10’ ribbed water channel panels (1 is new and unused, 4 need one replacement header each, 25 others were working fine at disassembly last week). These currently retail for $107 each.
- 58 distribution headers (56 are still attached to the panels, one at each end, 2 are new and unused).
Clips and O-rings for headers.
- Aqua Solar electronic solar control centre with 2 in-line temperature sensors and with manual (controls the actuator valve to send/receive water to/from heating grid depending on pool water temperature and solar system water temperature). These currently retail for about $730).
- GVA-24 valve actuator (new in 2022), with manual.
- Miscellaneous PVC pipe lengths, some with fittings.

I've passing this system on primarily because I'm looking at installing a photovoltaic system on my roof to generate electricity for multiple household purposes.

Photos show 1) the collection of components with the panels in rolls 2) the system as it was on my roof 3) the control panel, 4) the actuator and piping.

Condition:
- The ribbed panels seem as good as new. They have never leaked.
- The headers are more susceptible to UV degradation. I've replaced 4 of them in the past few years ($70 for 4 from Pool Supplies Canada), and always kept a couple of spares on hand. They are easy to replace.
- The control panel has never been exposed to the elements and has never been any trouble - it looks new.
- The actuator was replaced this year. As the actuator handle moves from one position to the next it leaks a bit, but it does not leak at all once in position. The leak is from the original lower half of the device. The leak was so trivial that I never bothered opening it up to see if a gasket or ring needed replacing.
