Vitocal 350-G: Viessmann - Germany


Heat pump with a maximum flow temperature of 72 °C.The first choice for radiator and DHW supply in houses and apartment buildings

Extremely quiet and economical operation

With its anti-vibration and sound-optimised design, the Vitocal 350-G is extremely quiet.This means the heat pump can even be sited close to living spaces without causing a problem.

The innovative RCD system, which provides continuous refrigerant cycle control, ensures high efficiency at any operating point.

The use of an electronic expansion valve (EEV)and high efficiency pumps (with type BWC),as well as a efficiency of 460% contribute to the very low running costs.

Vitotronic 200 control unit with communication capability

Following a standardised operating philosophy, Viessmann now uses the smart Vitotronic 200 control unit in all its heat sources. The extensive functions include user guidance with Heat pumps Vitocal 350-G menu prompts, an integral diagnostic system, control of the instantaneous heating water heater, control of an additional  oil or gas boiler, and of course, the natural or active cooling functions.

Furthermore the Vitotronic 200 is capable of communicating via the Vitocom 300 module. This allows the heat pump system to be set up, monitored and optimised over the internet.

Take advantage of these benefits:

  • Brine/water heat pump Heating outputs, single stage: 7.3 and 18.3 kW, two-stage: 14.6 and 36.6 kW
  • Water/water heat pumpHeating outputs, single stage: 10.3 and 25.4 kW, two-stage: 20.6 and 50.8 kW
  • Low operating costs through high coefficients of performance: COP value(COP = coefficient of performance) to EN 14511 up to 4.6 (brine 0 °C/water 35 °C)
  • Fast DHW supply
  • High efficiency all year round at any operating point through innovative RCD system (continuous refrigerant cycle control)
  • Mono mode operation for central and DHW heating
  • Extremely quiet operation through sound-optimised appliance design
