The sun can radiate the annual energy consumption of the world's population onto the earth in less than four hours - completely free of charge. Per annum approximately 1000KWh of solar energy is irradiated onto each square metre of the UK and Eire, representing the energy content of 100 litres of fuel oil.

Utilising the free energy offered by the sun
The energy irradiated on to the ground can be utilised thermally as well as through photovoltaic conversion for generating heat and power.
Solar heating collectors are an ideal supplement to any heating system and contribute consistently to lower energy consumption.
An advanced and worthwhile addition to any modern heating system
Highly efficient solar collectors from our preferred suppliers Viessmann help you to save up to 35% of your total heating costs, if you utilise them for both Domestic Hot Water heating and central heating backup. When used for domestic hot water alone they can save you up to 60% of your annual consumption.
The solar panels used by HeatNet are manufactured by Viessmann who are a leading European manufacturer of solar heating systems and can draw on more than 30 years of experience in the sector.
The heating system that loves the environment
Even when it comes to environmental compatibility, Viessmann solar heating systems are on the sunny side of the street: on average, in a detached house, about 750kg less carbon dioxide (CO2) is produced.
Future proof
All Viessmann solar systems installed by HeatNet are distinguished by their high operational safety and long service life. No wonder: the solar collectors are made of corrosion and UV resistant materials. This is most impressively verified by quality tests according to the EN 12975 test standard, which at the same time also confirms the consistently high thermal output.
Designed suitable for recycling
All Viessmann systems are also designed with recycling in mind. Viessmann solar collectors are designed for an exceptionally long service life, however, they are also designed so that at the end of their life they can be easily recycled, with all components identified according to type.
