stainless steel hot water tanks
A stainless steel hot water tank is designed to heat large quantities of water pressure-free. Heating is by means of a heating coil that can be connected to an external heat source. By heat source is meant, for example, a gas or wood-fired central heating system. Hot water tanks can also be combined with energy solutions such as solar panels. The hot water tank is equipped with a standard level control that switches on a height difference of 15 mm for refilling (hot) water. The boiler or hot water tank can be designed in three variants:
- Standard tank with a red copper heating coil (standard with 8 loops, maximum with 11 loops)
- As under 1; but with a circulation system to ensure that the contents become a homogeneous mass
- Standard tank with a stainless steel heating coil (standard with 12 loops)
The stainless steel hot water tank from VOLTMAN have been on the market for many years and are known for their high quality. The boiler is manufactured from stainless steel 316-L as standard, is well insulated and is perfectly finished. The stainless steel hot water tanks are designed and built according to the European Machinery Directive. Thanks to in-house production, adjustments are always possible.
