ENERSOLAR SLE Solar system with natural circulation | Thermostahl România
ENERSOLAR SLE - Natural circulation solar system

THERMOSTAHL ENERSOLAR is a natural circulation system for hot water production from solar energy. The solar collectors have selective surface for maximum absorbance and are covered with high strength tempered glass.

The water tank has an internal glass coating and external insulation of injected polyurathane for minimum heat losses. The system is very easy to instal and ensures safe and efficient function. It is also equipped with electrical resistance with safety thermostat and anode protection. Optionally, it can be equipped with serpentine heat exchanger for connection with the central heating boiler.

The system comes together with metal support for easy installation on flat or inclined roof.
