5. Environmental protection
Using renewable energy, such as solar energy, allows for the reduction of CO2 emissions and caring for the natural environment. By choosing our sets, you contribute to protecting the planet for future generations.

Heat Buffer Essential with Solar Collectors

Solar collectors, combined with a buffer equipped with a copper coil for heating technical water in the buffer, store their thermal energy. This energy stored in the technical water is used to heat domestic hot water on a flow-through basis using a second coil for DHW, and to power or support central heating installations, such as underfloor heating or radiators.

Buffers with copper coils are particularly effective because they provide excellent heat exchange efficiency compared to buffers with steel coils. Such a solution often means that the number of collectors needed to meet domestic hot water needs can be up to 30% less.

Efficient Installations for Central Heating and Domestic Hot Water

The heat buffer and solar collectors also serve as a heat source for heating the building in spring or autumn.

A properly designed and executed solar collector installation is key to satisfying 55-75% of the annual demand for heating domestic hot water. However, to achieve the best efficiency, which allows us to also support the heating of the building during transitional periods, it is essential to use a high-quality NOEL heat buffer with two copper coils of appropriate heat exchange surface area and flow. Such a combination will enable our installation to power the heating of the building or pool, reducing heating costs, and providing hot water from April to September without additional expenses.

The above diagrams are simplified and do not replace the installation project.
They are only auxiliary conceptual developments helpful in project development. The diagrams do not show necessary protective and regulatory elements. Protections should be selected in accordance with applicable regulations. Connection of heating devices and fittings should be done according to the manufacturers’ recommendations. Pipe diameters, fittings used, and their connection method should be adjusted to the required flow rates of the heating medium provided in the instructions. If you need help with connecting the Noel tank, contact our technical department.
