Vitocal 151-a

Key Benefits

Maximum efficiency with minimum energy consumption

Reliable, compact and greener than ever: the latest innovative Viessmann heat pump technology makes it possible to use energy from the ambient air for heating and cooling. With a flow temperature of up to 70°C, the Vitocal 151-A model was designed specifically for renovation. You can continue to use your existing radiators, without necessarily having underfloor heating. The strong points: high energy efficiency, simple operation via a dedicated app, long-lasting operation and an attractive design.

Climate Protect +++ preserves the environment and the climate

The new heat pumps in the Vitocal 15x range use the refrigerant R290 (propane), which is considered particularly environmentally friendly and has an extremely low GWP100 (100-year global warming potential) of 0.02.

Hydro AutoControl – reliable operation at maximum efficiency

Modern heat pumps from Viessmann work with the patented Hydro AutoControl® hydraulic system, which allows the heat pump to be operated reliably at maximum efficiency over its entire service life. This unique design allows on the one hand a much faster implementation of the heat pump, associated with reduced installation costs, on the other hand to have a much less bulky system, since it is up to 60% more compact than its market competitors.

Compatible with both existing radiator setups and underfloor heating.

Service Link – faster intervention in the event of breakdown or maintenance

Thanks to wireless technology, the devices of the Vitocal 151-A series are permanently connected to the Viessmann service centre at no additional cost. Any faults are communicated directly and without delay to the installer, who can immediately take the necessary measures. This avoids any unnecessary travel, saving time and money.
