HOA Adds Solar Pool Heating to Community Pool

The HOA wanted to resurface this community pool, and the
members called Go Green Solar Solutions. They wanted to see what they could do to update the pool and save money on their gas bill.

In-Deck Solar Pool Heating

GGSS came up with a cost-effective plan: Install a 6,000 sq ft in-deck solar pool heating system, upgrade the existing pool electrical meters, and upgrade the pool pumps to variable speed pumps. These upgrades save over $1,500 per month in gas costs.  They also improve the year-round swimming visits by 50%. “This is great,” one resident raved. “We used to only come in the summer, but now the family is coming to the community pool year-round, and it’s warmer than ever before.” The upgrades are a win for everyone.  They eliminate the HOA pool gas heating bill, plus cut the electric bill in half. The improvements also keep the community pool open year-round, and CSI rebates reduced the cost of the project.

Solar Pool Heating – Swimming in March with No Heating Bill

We couldn’t be more pleased with our solar pool heating system.  We have been swimming since late March, and the pool has been 85 to 90 degrees without turning on the gas heater.  But there are some good reasons why we’ve been able to maintain that temperature.

The solar pool heating system heats up the pool during the day, but that heat will be lost at night if you don’t use a pool cover.  As you can see from the picture, we cut the bubble cover we got when we built the pool to fit the pool almost exactly.  We also bought a pool cover reel to make it easy to put the cover on and off.  Without the reel, I think the cover would be too difficult to deal with.  Now, it’s one man (or woman) job to put the cover on or off.

We usually end up swimming on the weekends, and just leave the cover on during the week.  The pool will usually maintain its temperature over the weekend without the cover.  We’ve actually wanted to cool the pool down a little on some of our warmer weekends, and that happens at night without the cover.

Solar Heating for the Pool – Working Great

The final installation for our two solar pool heating systems was completed last week, and we couldn’t be happier with the performance.  We installed two systems, a rooftop system (the dark panels below the solar electrical panels on our roof), and an in-deck solar heating system (underneath the concrete around the pool.)  The system begins to pump warm water into the pool as early as 8am, and continues until late in the afternoon. (We do have an ideal south-facing roof.)  We set the desired temperature, and a separate pump operates whenever the water in the solar panels is hotter than the pool temperature.  It shuts off when the desired temperature is reached.  The system pumps out an amazing amount of hot water — the kids are getting exercise by positioning themselves where the water comes into the pool and swimming against the current.

The in-deck pool heating system has an added advantage, also.  The concrete around the pool used to be too hot to walk on during hot afternoons, but now with the cooler water circulating underneath it, the concrete is much cooler.  The heat is carried to the pool.

The goal is to not use the pool heater at all.  We’re going to be careful to use a pool cover at night when the weather gets colder, and between that and the solar heating systems, we’ll see how warm we can keep the pool.

Solar Heating for the Pool – Concrete is poured and pool is finished.

As the next step in our in-deck solar pool heating adventure, concrete was poured over the solar heating tubes.  When the concrete was poured, workers made sure that the tubes were approximately 2″ below the concrete surface.  This maximizes the heat that is transferred to the tubes, without the possibility of the tubes showing in the concrete.

To the right is the finished pool and deck.  The concrete gets very hot in the direct sun, so we’re looking forward to turning on the solar.  We can’t turn the heat or solar heating on until a  month has passed so the pool surface can cure, but the temperature without heating is a very comfortable 85 degrees.  The rooftop pool solar and in-deck solar heating will allow us to extend our swim season year-round, without increasing our utility bill.  I’ll bring you an update when the solar is turned on and let you know how it affects our heating bill.

To the left you can see the rooftop solar pool heating panels on the roof, below the solar electrical (PV) panels.  We used ten 4 ft. by 8 ft. Heliocol panels.  They are shorter than the normal Heliocol panels, designed for roofs that don’t have room for the larger panels.  Solar pool heating is the most cost-effective use of solar in your home, with a return on investment of just 2-4 years.  We’re looking forward to swimming into the fall.

 

Solar Heating for the Pool – Solar Tubing is Placed

The installation of our in-deck solar heating system is progressing.  The forms for the concrete were put in place, and then solar tubing was coiled where the cement will be poured.  As you can see from the pictures, as much tubing was put into the cement forms as possible.  The tubing should be about 2″ below the finished surface.  Darker deck surfaces work better for better heat absorption.

Deck coverage should be about 200 percent of the pool surface area, but we’re just putting in a small system to augment the Heliocol solar pool heating system that will go on the roof.

In-deck solar pool heating is appropriate for pool decks, tennis courts, driveways and sport courts.  It will also cool your deck or tennis court when the cool water is pumped through the tubing.

Call us for more information on in-deck solar pool heating, rooftop solar pool heating, solar electricity, radiant heating, and solar domestic hot water.  We can show you how to reduce your home’s utility bills, and extend your family’s swim season without paying more to heat your pool.

Next step … concrete is poured.

Solar Heating for the Pool – the Adventure Begins

At our home in Westlake Village, we power our home with a dual solar electrical system.  A 9.2kW Kyocera system is on the roof, and we also have a 3.2kW patio cover system.  Because of these two systems, we don’t pay an electric bill, and when we recently decided to put in a pool, we were concerned about the added cost each month to heat it.  Our home, our car, and our business are all  powered by solar, so we thought it was only natural to heat our pool with it.
We have a small yard, so we’re only putting about 100 square feet of concrete around the pool, but we decided to put in a small in-deck pool heating system.  Tubes are put into the concrete when it’s poured, and water is circulated through the tubes.  When the cement heats up, it heats up the water, and that warm water is circulated to the pool.  The cool water running through the cement (before it heats up) also serves to cool down the concrete slightly.  This system works well for people who are putting in new cement and don’t have a lot of room on their roof for a rooftop pool solar heating system.  We’re also considering adding some rooftop pool solar.  There’s not a lot of room because of the solar electrical system, but Heliocol now has some small rooftop panels available.  Between that and the in-deck system, we should be able to cut our pool heating bill substantially.
We will post updates and pictures on the installation as it progresses.
