Power Tanks – Heat Storage Tanks

Heat Storage Tanks are a revolutionary, new technology, developed in Germany, which, when coupled with “Sun Stream” solar heating panels, can reduce oil or gas consumption by as much as 70%. They can be used in both domestic and commercial applications, with equal success.

They are certified to the highest German quality standards and hold the TUV certificate. They are guaranteed for 10 years, but have an expected life of over 100 years as there are no moving parts, include no corrosive materials and need no maintenance.

What are Sun Stream Heat Stores or Power Tanks?

The Heat Store or Power Tank is a latent energy storage system ideal for domestic and commercial installations which will effectively improve boiler efficiency and maximise the solar gain from Sun Stream solar collectors.

It achieves this by storing all excess heat generated by the solar collectors, at the same time reducing the boiler cycle i.e. the number of times the boiler fires-up, by as much as 90%.

90% of all heating systems are operating in an inefficient range, that means that systems switch on and off 30- 40000 times per year. This leads to high energy consumption, soot production in the flue gases and increased technical wear in the system.

The integration of Sun Stream Heat Storage Tanks reduces the response times down to 3-4000 cycles (depending on boiler type) thus achieving a substantial increase in boiler efficiency. At the same time they permit the installation of larger than normal solar thermal systems, as all the excess heat can now be stored and used later.

Sun Stream Heat Storage Tanks are available for both vertical and horizontal fixings, therefore most properties can be accommodated, including garages, basements and lofts. A smart controller is required to manage the system.

Heat Storage Tanks can be integrated into the following systems :-
