Solar thermal
Indirect solar water heaters that harvest the sun for the bulk of your hot water and quietly top up on electricity only when the weather won't cooperate. Because they are indirect systems, the collector fluid and your domestic water never mix so they work with any water quality and hold high pressure.
What it is
A solar collector heats a fluid, that fluid transfers its heat to your water through a heat exchanger, and an insulated tank stores it. The water you use and the fluid in the panels stay completely separate — cleaner, more hygienic, and safe on hard or borehole water.
How it works
Collectors on the roof capture solar heat throughout the day.
Heat passes to your domestic water through a sealed heat exchanger — no mixing, no scaling of the panels.
An insulated tank stores hot water for when you need it.
An electric booster tops up automatically on cloudy days, so you never run out.
System types
Tank and collector both mounted on the roof. The simplest, most reliable, most cost-effective option — no pump, no moving parts.
Slim collectors on the roof, tank hidden indoors. Maximum flexibility and a cleaner look — ideal for weak or steep roofs.
The payoff
Models
200 DP
Compact indirect (double-jacket) thermosiphon system: a 185 L horizontal tank paired with a high-performance flat-plate collector. Runs on any water quality, holds high pressure, and includes an electric booster for cloudy days.
300 DP
Higher-capacity indirect thermosiphon system with a 290 L tank and twin collectors for larger households and steady demand. The same rugged double-jacket design that runs on any water quality, with electric backup.
