Product characteristics

  • BW hot water boilers with volumes of 200, 300, 400, 500, 800 and 1.000 liters are intended for heating and accumulating domestic hot water by connecting it to a boiler circuit or to another heat source within a technological process.
  • They are suitable for installation in solar systems, as additional accumulation with BE solar boilers.
  • Enameled water heaters are made of high-quality stainless steel, which guarantees high hygienic conditions.
  • Due to the rapid heating with a large heating surface of the tube exchanger, they provide the comfort of large quantities of hot water.

Delivery and installation

  • The BW hot water heater is delivered on a pallet with factory-mounted insulation and a protective magnesium anode.
  • If the entrance door to the room is smaller than the boiler, the insulation can be removed and then re-mounted in the room (only on BW 800-1000).
  • At the cold sanitary water inlet to the boiler, it is mandatory to install:
    - expansion tank for sanitary water
    - tap for draining water from the boiler (mandatory via T-piece)
    - certified safety valve with an opening pressure of 10 bar (1.0 MPa),
    - non-return valve
    - pressure reducing valve that reduces the pressure of the cold sanitary water inlet to 4 bar (0.4 MPa) (if its pressure is higher).
