Low running cost
Once installed, solar heating adds warmth with minimal ongoing cost.
Sunshine is free energy. WETYR Pools designs and installs solar pool heating that warms the water and lengthens your swim season with almost no running cost.
Solar pool heating circulates pool water through roof-mounted collectors that the sun warms, then returns it to the pool. After installation, the heat is essentially free. It is the most cost-effective way to extend the swim season, and it pairs perfectly with a pool cover to hold the heat in.
WETYR Pools handles solar heating as a craftsman-led, design-build team. The people who plan your project are the people who build it and stand behind it, with no quality lost in the handoffs between separate companies. One team, one standard, and one point of accountability from the first conversation through long-term care.
Most homeowners discover an uncomfortable truth a year or two after building a pool: an unheated pool is genuinely pleasant to swim in for only a fraction of the year. Even in warm climates, water that is not heated runs cold in the cooler months and through every cool snap, and a pool nobody wants to get into is an expensive ornament. The gap between the swimming the calendar promises and the swimming the water actually allows is wider than people expect.
Heating closes that gap, and the question is simply how to pay for the heat. A gas heater buys warmth by burning fuel, and the meter runs the entire time it is on. An electric heat pump is far more efficient but still draws power. Solar pool heating answers the question differently: it buys the equipment once and then takes the heat from the sun, for free, for the life of the system.
WETYR Pools designs and installs solar pool heating for homeowners who want a longer, more comfortable swim season without a running cost that climbs every time they use it. It is the most economical way to heat a pool over the long term, and in a sunny climate it is also one of the most effective.

Comfortable water earlier in spring and later into fall.
Combine solar heating with a cover to retain heat overnight and boost efficiency.
No combustion, no fuel, and very little maintenance.
Solar pool heating is appealing partly because the idea is so straightforward. There is no combustion, no fuel, and no complex machinery, just water, sunlight, and circulation.
A series of solar collector panels are mounted, usually on the roof, where they catch direct sun. They are dark and designed to absorb solar heat efficiently, and they have no moving parts of their own, which is a large part of why the system is so durable and low maintenance.
The pool's own pump diverts water up through the collectors, where the sun warms it as it passes, and then returns it, warmed, to the pool. In most cases no separate pump is needed, so the system adds heat using circulation the pool is already running.
An automatic controller decides when to send water to the collectors, sending it up when the panels are hotter than the pool and holding back when they are not. The system heats when conditions are right and stays out of the way when they are not, with no daily input from you.
Solar heating adds warmth during the day; a pool cover keeps that warmth from escaping overnight. Used together they are far more effective than either alone, which is why we so often recommend the pair.
The economics of solar pool heating are different in kind from gas or heat-pump heating, not just different in degree. With a gas heater, every comfortable swim has a fuel cost attached to it, and that cost rises with fuel prices for as long as you own the pool. With solar, the meaningful cost is the installation. After that, the sun does the work, and the marginal cost of a warm pool is effectively zero.
That changes how the system is judged. A solar heating system is best understood as an investment with a payback period: it costs money up front, then it pays that money back in heating costs avoided, year after year, and once it has paid for itself it simply keeps delivering free heat for the remaining life of the equipment. Solar collectors are long-lived, so that period of free heat is long.
It also removes a quiet psychological cost. With a metered heater, many owners ration warmth, hesitating to turn it on because they can feel the money burning. A solar-heated pool carries no such hesitation. The water is comfortable because the sun made it comfortable, and you use the pool freely. That freedom to actually use what you paid to build is a real part of the value.
Solar pool heating can be added to most existing pools, not just new builds. The main requirement is suitable space with good, largely unshaded sun exposure for the collectors, typically a section of roof, though ground or rack mounting is sometimes an option. WETYR Pools assesses the available area, the orientation, the sun exposure, and the pool's size, and we size the collector array to deliver a meaningful temperature gain rather than a token one. An undersized system disappoints; a correctly sized one delivers.
Solar heating also fits naturally into a larger efficiency strategy. It pairs with a pool cover to hold heat overnight, and it works alongside a variable-speed pump and smart automation so the whole pool runs on as little energy as possible. For our off-grid natural pools, solar heating is a core component, taking the chill off the swimming season using nothing but sunlight, in keeping with the low-impact goal of the whole design.
Whether the project is a solar system added to a pool you already own or designed into a new build alongside efficient equipment, it begins with a clear, fixed, itemized proposal. Clean, quiet, and nearly maintenance-free, solar heating is one of the easiest upgrades a pool owner can feel good about for decades.
Clear answers to the questions homeowners ask most.
Very well in a sunny climate. The collectors capture solar heat and the pool's circulation carries it into the water. It reliably extends the comfortable swim season, and it works best when paired with a pool cover to hold the heat in overnight.
Yes. As long as there is suitable space with good, largely unshaded sun exposure, usually a section of roof, solar collectors can be added to most existing pools. We assess the area and orientation and size the system to your pool.
Almost nothing. The meaningful cost is the installation; after that the heat comes from the sun for free. In most systems the pool's existing pump provides the circulation, so there is no significant separate running cost.
No. Solar collectors have no moving parts of their own, which makes the system clean, quiet, and nearly maintenance-free. It is one of the lowest-upkeep ways to heat a pool.
A solar system is an investment with a payback period: it costs money up front, then pays that back through heating costs avoided, year after year. Once it has paid for itself it keeps delivering free heat for the long remaining life of the equipment.
Yes, and it is a core part of our off-grid designs. Solar heating, a variable-speed pump, smart automation, and a cover work together so a pool, including a natural pool, can run on very little energy or none from the grid at all.
