Pump unit with electronic adjusting for DHW production
Pump unit to deliver domestic hot water (DHW) with thermostat regulation and high-efficiency circulation pump. Ideal for inertial storage tanks (buffer vessels) connected to traditional heating circuits, or wood-fired, pellets, biomasses etc., where stratification is not a fundamental requisite. The device guarantees production of instantaneous domestic hot water while avoiding bacterial pollution such as legionella etc., which are due to stagnation of the heated water in the tank.

  • BRAZED PLATE HEAT EXCHANGER in stainless steel AISI 316L
  • ELECTRONIC VARIABLE SPEED SINGLE CIRCULATION PUMP PRIMARY SIDE
  • DIGITAL FLOWMETER for temperature and flow rate reading
  • ELECTRONIC CONTROL UNIT for programming, control and accounting for the energy used
  • CIRCULATION PUMP DOMESTIC WATER SIDE (included only in the version with domestic water pump)
  • PPE HEAT INSULATION
  • REAR METAL PLATE for wall or tank mounting
