The Cleverest Solar Thermal System in the world

Ths unique points of the Solesta thermal solar system:

Legionella safe

The Solesta system does not heat stored tapwater in the boiler but instead uses the water as energy buffer. With a internal heat exchanger, tapwater is heated on the fly. Because there is no large quantity of water stocked, with a possible temperature between 20-50 degrees, legionella will not grow in the tapwater storage. The small capacity, copper heat exchanger (1.5l) will be refreshed at every tapping and copper is a bacteriostatic material. A safe feeling.

Compact, light weight and high efficiency

The flate plate collectors can be roof integrated, but also on-roof or flat-roof mounting is possible. Because of the small weight (18kg) they can be easily and cost effectively installed. The boiler itself (16kg) is compact enough to fit in small spaced and can therefore be installed in most houses. Despite the compactness and leight weight of the system, the efficiency is still very high compared to other systems.

Reliable

The system is designed with as few components as possible. To reduce the chance of a failure, there is no external pump, no pcb board, no display or even analog sensors. Because of the reliablilty of the system, Solesta is giving 10 years of warranty on the complete system as standard.

Flexible

The system can be designed with 1, 2 or 3 collectors or 15, 20 or 24 heatpipes. Two boilers can be used in parallel to increase the storage amount. Also PV panels in the same look and feel as the flatplates are available (projects only).

Sustainable and social responsible

The energy generated is not the only sustainable thing about the Solesta system. There is no glycol used in the system, just ordinary water in a drainback configuration. This saves money on yearly maintenance costs and water does not effect the environment as glycol does. Recycled materials are used in production and most of the components are recyclable. The system is assembled in the Netherlands at sheltered workshops.
