Tomorrow's Technology - Available Today!

The Forstner HS is the ideal all-in-one combination of heating centre and hygienic hot water boiler. Solar energy systems, biomass boilers and all conventional heating devices can be tied into the system with maximum efficiency. This will save you heating costs.




Quality Is Our Standard
For us, the most modern production techniques and highest precision go without saying.

Temperature Layers
Special thermohydraulic compensators (thermohydraulic layer modules) control thermal and dynamic processes during heat reception or distribution and guarantee optimal temperature layers.

Tap Water Heating
The flow-through heater, following physical principles, is ideally integrated into the heat storage unit. Heating of tap water occurs in a linear pattern from the cool to the hot range of the storage unit and creates a continuously self-perpetuating maximum layering of temperatures. Your advantage: you will always have hot water, even when the storage unit is only partially full.

The Highest Level of Hygiene
The contents of this unit, which are small in relation to the large exchange surface, are replaced several times a day. Legionella and other bacteria are given no chance to breed or pose health risks.
Large heat exchange surfaces mean a gentle heat transfer (no disproportionately overheated spots). In conjunction with other advantages, such as short delay times and high liquid turbulence, the precipitation and accumulation of mineral deposits are greatly minimised.

Solar Heat Exchanger
he solar heat exchanger is situated at the very bottom, in the coolest part of the storage unit. This allows it to reach the highest level of efficiency and maximum functionality. Thanks to the unique design, flow turbulence and the very thin walls of the corrugated pipe, considerably better K-values are achieved than with conventional exchangers.

The corrugated pipes in the solar heat exchanger and boiler are manufactured from top-of-the-line 1.4404 (V4A) stainless steel.

Connections

All connections in the heat storage unit comply with the conventional industry standards and are optimally situated. You can easily connect all heating devices to the proper spot. We've even taken into consideration future installations, such as additional storage units for increased capacity, etc. The connections are already in place.

Thermometer/Sensor

The plastic cartridge for the temperature sensor and thermometer is a technical innovation. Heat loss is considerably reduced, making it substantially lower than with conventional connections. Unreliable threaded seals and time-consuming installations are history.
