MultiVal ERR/ESRR

MultiVal ERR/ESRR


Calorifier with 2 heat exchangers (coil) for heating using 2 heat sources. The primary heat generator is usually a solar energy system. Any heat generator (e.g. heat pumps, biomass boilers, condensing gas/oil boilers) can be used as the additional heat source. Supplementary heating can optionally be provided by an electric heating element or an integrated heat pump (CombiVal WPER).

  • Calorifier and plain-tube heat exchanger made from robust steel with corrosion-resistant enamel coating
  • 2 enamelled plain-tube heat exchangers for incorporating 2 heat generators:
    • Primary heating by means of the solar energy system
    • Supplementary heating via boiler (wood pellet, log, oil or gas boiler)
  • Model ESRR with large heat exchanger in the upper region especially for operating with heat pumps
  • Electric heating element available for additional heating
  • Low heat loss owing to highly effective thermal insulation
  • Flange opening can be used for cleaning or for installing the electric heating element

Types:

  • MultiVal ERR (300-1000): 2 heat exchangers 0,8 – 1,2 m2 and 1,55 – 3,4 m2
  • MultiVal ESRR (500-1000): large heat exchanger in the upper region especially for operating with heat pumps 4,3 – 6,1 m2 and for solar usage 1,85 – 3,4 m2
