Heat transfer
Raw steel hot water cylinder with 2 fixed coils for heat storage from heating circuit and 1 removable coil for the instant production of DHW

  • The hot water cylinders RM3 series are storage tanks for heating plants which allow significant cost saving by using alternative and renewable energy sources or by recovering other energy sources
  • Suitable for storage and production of hot water from heating circuit
  • They allow DHW production by means of the removable copper coil
  • They function as against-condensation circuit by using biomass heat generators
  • They allow to separate the primary and secondary circuits
  • Both primary and secondary plants can be widened by connecting other energy sources
  • Used to exploit discontinuous heat generators such as: solar panels, boilers, stoves or solid fuel fireplaces
  • The burner interventions are limited in the low content water plants
  • Suitable for exploitation of solar or heat pump plants
