Storage reservoirs (VAN)
The VAN storage reservoirs bring outstanding improvement of operation for any type of central heating system boiler for solid fuel such as coal, coke, wood, briquettes, wood briquettes, straw, etc., especially for wood and coal gasification boilers; and nearly absolute utilisation of the heat energy produced.
They can be connected to heat pumps and solar systems as accessories. The VAN storage reservoirs can be operated under working overpressure up to 0.6 MPa and under working temperature up to 100 °C. The upper inner tank serves for pro storage heating of hot service water, while the lower tank is used to discharge a solar source or a heat pump.
The reservoirs are coated with environmentally sound primer; the inner tank is galvanised; standard volume 150 l. Heat-delivery surface of the solar source is 1.4 sq.m. Special storage reservoirs upon customer’s request.
