About Solcrafte® - solar water heater system

THE VISION OF SOLCRAFTE®

The energy situation worldwide is characterised by limited natural gas and crude oil reserves, but by increasing consumption. Moreover, additional Co2 emissions are heating up our atmosphere, resulting in alarming climate change. This enforces a more responsible energy-handling policy. What we need is more efficiency, with an increase in the use of renewable energy sources. Solcrafte® – the first tankless solar water heater – allows you to cover up to 90% of the energy required each year for heating domestic water. Solcrafte® is the new generation of design-orientated compact solar solutions without any external tank.

Free. Hot. Water.

That is Solcrafte®’s vision and it has a future. The innovative Solcrafte® solution allows everyone to use the sun effectively to collect energy. Tankless hot water systems make it possible to use free solar energy even better. Solar water heater systems are also more efficient and twice as fast as conventional thermosiphon systems. This results in energy cost savings of up to 90 percent in the production of sanitary hot water.

The sun is the best renewal energy source of the future! Solcrafte® allows you to tap hot water 365 days a year while saving energy. This saves resources and thus the environment, increasing supply reliability and saving you money. Solcrafte® allows you to save up to 1,180 kg Co2 per year, thus making an important contribution to a liveable future, providing future generations with a high quality of life.

THE INNOVATION OF OUR SOLAR WATER HEATER

Solcrafte® demonstrates that a modern solar design can be used to create striking and efficient solar water heater systems. Solcrafte® is a revolutionary, integrated collector storage system in which both performance and product design constitute significant factors. The water is directly heated and stored in the system, thus significantly increasing its energy efficiency. Solcrafte® is thus the ideal compact solar solution for detached houses, villas, holiday and weekend homes!

THE FUNCTIONAL PRINCIPLE

The idea of Solcrafte® differs from that of conventional thermosiphon systems in that the heat storage is integrated into the system. The classic 2-circuit thermosiphon principle has been improved by further developments and improvements to create a compact, unpumped 1-circuit system. As various components such as the solar pump, heat exchanger or combination storage are falling away, Solcrafte® is compact, quick to install, space-saving and low-maintenance – the perfect solar water heater!

The integrated collector storage system is directly connected to the water pipe and water thus flows through it at the normal pressure. This means that the water becomes a heat transfer and consumption medium. The fresh tap water flows through the system from the bottom to the top, resulting in heating of the medium by solar radiation. The temperature-dependent sealing function of the water allows for layering in the system. The hot water rises, due to its lower specific weight. Depending on the type (100, 150 or 200), the system has 3, 5 or 7 heating pipes specially designed for solar applications integrated into the system. The pipes are suitable for drinking water and connected to each other with plastic caps specially produced and patented for this system. The water to be heated flows in serpentines through the pipes, thus the incoming cold water cannot mix with the solar-heated water.

The fact that the heat transfer medium of the integrated system is the same as the consumption medium means that there are no transfer losses between the media. Even the slightest radiation can therefore be converted into heat and utilised effectively.
