Has anyone tried this? https://universalconstructionfoam.com/projects/expanded-polystyrene-sheets-for-pool-cover/

I wish to add a heat pump to daily warm my 20,000-gallon pool with pool cover during the winter in San Francisco East Bay. My roof top water solar keeps the pool warm enough April 15 - Oct 15. Winter outdoor temperatures are typically 45F low to 60F high. I can swim daily down to 65F pool...

I don't know what "Solar Power Rate" is. I am under California NEM 2.0 for solar. As a rough estimate, on an annual basis, I pay $0 for anything I generate and use. On an annual basis, I receive close to $0 for anything I generate more than I use. Since installing the panels, I have a small...

I don't know how many btus I would add to the pool each year - so many variables and too many unknowns. I have a 20,000 gallon pool and want to go swimming daily but no colder than 65F. Wild guess: 7 therms a day * 180 days / winter = 1260 therms a year * 100,000 BTU/therm = 126,000,000 BTU /...

That was my impression. I may instead go for a heat pump - perhaps AquaCal SQ166R or SQ225. I may also get the Raypak R406A 009219 natural gas heater to get me through when it gets too cold for the heat pump. My impression is that folks have had good experience with these heat pumps and...

I made it up. I would love to swim daily during the winter. April 15 - Oct 15 I would use the roof top solar to heat my pool, not a natural gas heater. My impression is that high-efficiency heaters often require significant attention and significant annual maintenance to keep them running...

I would consider any - I'm thinking 400K BTU, but open to any that someone has had a good experience with.

I wish to add an uncovered, outdoor natural gas heater to daily warm my 20,000-gallon pool with pool cover during the winter in San Francisco East Bay. My roof top water solar keeps the pool warm enough April 15 - Oct 15. Winter outdoor temperatures are typically 45F low to 60F high. I can swim...

Thank you for posting all of this!! I want one! Are you using a pool blanket? Do you get winter frost or snow? Do you plan to swim through the winter? Do you get a lot of condensate? Will the condensate freeze? I live in the San Franciso East Bay. My 20,000 gallon pool has been my daily go-to...

Thank you, Allen, I had to look up what "drain to daylight” means :) My swimming pool and backyard are virtually all concrete. I would have to break up the concrete to get to the dirt, except for an 8" strip of dirt along my rear fence, or the dirt on the side property line behind a retaining...
