Solar water heating, explained
Short guides on how a solar heating system works, what it costs to heat a pool and how solar collectors compare with a heat pump. Plain answers, with sources, from the engineers who install the systems.
Guides
Each guide answers one question in full. The solution pages link here instead of repeating it.
How much does it cost to heat a pool? Running costs by method
What a kWh of heat costs with a heat pump, electric heating, gas and solar, how much heat a pool needs, and a worked example.

Heat pump or solar pool heating: which fits your pool?
How each one works, a side-by-side comparison, when a heat pump alone is enough, when solar alone is, and why most pools end up with both.

Quick answers
The questions we hear most often, in short. The guides go deeper.
Does solar water heating work on cloudy days and at night?
The panels heat water whenever there is daylight, less on cloudy days, and not at night. That is why every system has a backup: a heat pump or the existing boiler, which the controller switches on automatically only when the sun isn't enough.
Can the system be installed in an existing building?
In most cases, yes: it connects to the existing pool equipment, hot-water tank, boilers or heat pumps. What can be connected, and where the panels go, we check at the site survey. You need a spot that gets sun most of the day; the orientation and tilt are set on site.
What maintenance does it need?
Little. The panels have no moving parts; an annual check and dusting of the tubes is enough. The app shows temperatures and system status, so anything unusual is easy to spot. The system comes with a 5-year warranty.
How long does installation take?
For a home or a pool, on-site work usually takes a few days after the survey and the design. Hotels and plants depend on the scope and are planned around the site's schedule.
