DS Matic H Duo

A solar heating system for domestic hot water production whose main feature is its innovative solar panel drain back system, in a closed circuit containing air and heat-carrying fluid.

The water heated up by the solar panels is stored in a stainless steel hot water tank, ready for use at the points of consumption.

With the ¨DUO¨ version, when there is no solar power or if it is insufficient, the back-up heat exchanger circuit enables the water in the tank to be heated by another energy source.

It is the ideal solution for single-family homes, and its wide range of models adapt to their different needs.

Overheating and anti-frost protection
The system automatically loads air into the solar panels when no more power is required or when there is no solar radiation. This prevents damage to the solar collectors themselves, due to either excess heat or freezing.

Stainless steel DHW tank
The hot water provided by solar power is stored in a stainless steel tank. This guarantees a long life for the system, as it is made of hard-wearing materials.

Energy performance
The system includes high-performance solar panels, which combine with the large hot water tank heat exchange surface to make exceptional use of the energy generated.

Fully equipped
Unlike most systems on the market, DOMUSA complements these units with all the installation accessories required: an expansion tank and DHW safety valve, and brass dielectric sleeves for the two circuits (solar and DHW).

Installing the system at a height
The ¨PLUS¨ version may be installed at heights of up to 15 m.

Electricity savings
When the solar circulation is balanced, one of the system pumps stops, reducing electricity consumption by 50%.

Ease of installation and maintenance
Its special design, with no expansion tank, drain valve or magnesium anode in the solar circuit, facilitates installation and maintenance.
