Water Heaters

The supply with hot water is very important for modern household. Right choice of equipment will last its exploitation period and help to avoid unnecessary payments for a repair.

Electric Water Heaters

  1. In all types of water heaters, a high-quality glass-ceramic coating is used to protect the inner surface of the tank from corrosion.
  2. Water heaters are equipped with a moisture-proof switch and a safe electrical part.
  3. Magnesium anode is built-in the construction to prevent scale formation.
  4. Water heaters are equipped with a steel flange providing free access to the magnesium anode and tubular electric heater.
  5. Water heaters use highly efficient thermal insulation of high density polyurethane foam. This ensures minimum energy loss and economical operation of the device.
  6. Water heaters of type GCVS have a built-in heat exchanger for connecting it to a heat supply source (heat exchanger capacity is 14.4 kW).
  7. Maximum working pressure - 8 bar.
