Drain-Back

A simple and safe solution for installing a solar-heated water system

The stainless steel tank is the heart of this solar energy system, subject to high pressures and changes in temperature. The stainless steel used in its construction is high quality chrome-nickel (stainless steel 304) welded under argon and Tungsten Inert Gas (T.I.G). Before assembly, the convex bottoms are pickled and rendered passive in order to improve the longevity of the tank in particular its resistance to corrosion.

The stainless steel coil integrated into the tank promotes a very high efficiency of energy exchange between the domestic hot water and solar heated water circuit.

Thermal insulation and cladding

High density injected polyurethane foam, 60 mm depth (containing no CFCs.)
Exterior cladding in polypropylene plastic which offers both a high impact resistance and an attractive appearance.

Advantages of the Drain-Back tank

Very low system cost due to integrated design
Inbuilt pressure control: eliminates the need for an expansion vessel, safety valve or air vent in the solar circuit
Simple Installation, straight-forward connections
Does not require specialist skills for installation
High quality materials and components, including the use of high grade stainless steel
Efficient and ecological performance in use
