High-capacity water heaters

High-capacity heaters – storage tanks are intended for central supply of domestic hot water. Fitted with large surface heat exchangers, they are suitable for use in central heating systems with heat pumps and solar collectors.

ADVANTAGES:

  • Simple connection to the heating system pipeline (connection with an outer thread)
  • High-quality PU insulation ensures low heat losses
  • Polystirena cover coat casing
  • Integrated heating flange with 3 kW electric air heating elements and regulation thermostat
  • Large heat exchanger surface
  • Versions with one or two heat exchangers
  • Tank made of high-quality steel sheet is protected with enamel coating
  • Additional anti-corrosion tank protection with a magnesium anode
  • Optional temperature sensor for external heat source
  • Available volumes/capacities: 200 l, 300 l, 400 l
