The next generation of heat pumps: The new Vitocal 150-A/151-A range

Day by day, technical progress makes our lives more pleasant and safer. New ideas are born that change the world. We are helping to shape this change – with intelligent solutions for climate and for comfort. "We create living spaces for generations to come," we also take responsibility for the things that come after us. The protection and preservation of our environment and the natural world that surrounds us is without doubt among the most important tasks that our society has to cope with. We see the energy transition and digitisation as a great opportunity. This gives us the guidelines...

The new generation of heat pumps The new Vitocal 151-A monobloc heat pumps with up to 70°C flow temperature are ideally suited for renovation projects. Reliable, compact and environmentally friendly like never before – with the new, innovative heat pump technology from Viessmann. Environmental heat can be used efficiently for heating and cooling. With a flow temperature of up to 70°C, the Vitocal 150-A/151-A range has been specially designed for renovation projects

Service Link – for faster response times The Vitocal 150-A/151-A range are always connected to Viessmann with Viessmann Service. Completely free of charge, the heat pump instantly transmits any faults. The installer can immediately take the necessary measures, which eliminates unnecessary trips, saving time and money. Climate Protect+++ protects the environment and the climate The Vitocal 150-A/151-A range use the "green" refrigerant R290 (propane), which is considered to be particularly environmentally "friendly", with a very low GWP100 of 0.02 (Global Warming Potential). Outdoor Vitocal...

HYDRO AUTOCONTROL Hydro AutoControl – reliable operation with maximum efficiency Viessmann Hydro AutoControl The new, patented hydraulics from Viessmann that make heat pump installations child's play. Viessmann heat pumps are particularly quiet and efficient. With their excellent design, which also includes the accessories, they set high standards. Due to the environmentally friendly, natural refrigerant propane, the heat pump can operate even at outside temperatures of -10°C. With 70°C flow temperature it is ideally suited for renovations This means that it can be used to heat existing...

Simplify the renovation of an existing system. To make the renovation of an existing system with the new Vitocal 150-A/151-A range as easy as possible, we have equipped it with a new, innovative hydraulic system. The patented Hydro AutoControl system simplifies the renovation of an existing system significantly. Significantly reduced space requirement due to Hydro AutoControl Hydro AutoControl – the heart of the device: 1 Hydro AutoControl forms the heart of the unit. It consists of four core components that interact with each other. 2 The 4/3-way valve distributes the hot water. In the...

HYDRO AUTOCONTROL Common problems in the heating circuit are solved with the new hydraulics: Insufficient circulation quantities due to closing radiator valves Hydro AutoControl regulates the minimum circulation volume If, for example, the room temperature changes due to warm weather, Hydro AutoControl reacts to the closing thermostatic valves and the resulting pressure increase in the system by opening the bypass valve. The flow rate is reduced until the minimum circulation rate is is reached. At this point the bypass valve opens again, so that the minimum minimum flow rate is always...

Freezing of the evaporator is prevented: Via the particularly efficient defrosting process An efficient defrosting process due to cycle inversion Especially at outside temperatures just above freezing point, the evaporator of an air-to-water heat pump installed outside starts to freeze. To prevent the evaporator from freezing, it is automatically defrosted. In modern air-to-water heat pumps, this is done by the particularly efficient defrosting process called cycle reversal. In this process, energy is briefly taken from the home network and used to heat the evaporator. Hydro AutoControl...
