Solar Thermal

Solar water heating systems take advantage of the free heat supplied by the sun to warm domestic hot water (DHW). These solutions provide DHW throughout the year, and they can be supported by boilers or immersion heaters to ensure you have hot water whenever you need it.

If you are planning to replace your existing boiler and already have solar panels on your home, many of our products are designed to support the use of energy from these panels to supplement your heating with a completely natural, green energy source. We also offer a range of solar collectors, and if you are investing in a new heating system, we advise you to consider designing it from the outset to incorporate these collectors. We provide evacuated tube and flat plate collector systems, both of which can be mounted on your roof.

Taking advantage of this renewable energy technology will help you to lower your consumption of mains energy, which in turn will reduce your fuel bills and cut your carbon footprint.

Solar Hot Water & Thermal Heating Systems

High performance flat-plate collectors are the perfect addition to any DHW or heating system.


With an individual absorber area of 2.3 m2, solar collectors can be effectively matched to any energy demand.

On average, they can replace up to 60 percent of the energy that would otherwise be required each year for DHW heating, as well as contributing to central heating backup.


When used in conjunction with a condensing boiler or heat pumps, free solar energy can help you reduce your annual energy consumption for heating and DHW by over one third.

These absorbers with highly selective coating collect a vast amount of solar energy and thereby ensure high efficiency.

At the same time, the vacuum in the tubes provides very effective thermal insulation. This means there are almost no losses between the glass tubes and the absorber, enabling the collector to convert even low levels of insolation into useful energy.


The vacuum tube collectors use the available insolation extremely efficiently, particularly in the spring and autumn, and in the winter when outside temperatures are low.


In these systems, the solar medium does not flow directly through the tubes.

Instead, a process medium evaporates in the heat pipe below the absorber and transfers the heat to the solar medium.

The dry connection of the heat pipe tubes inside the header, the small amount of fluid inside the collector and ThermProtect automatic temperature dependent shutdown ensure particularly high operational reliability.
