Highly suitable for modernisation: Vitocal 151-A

The new generation of heat pumps

Reliable, compact and more environmentally responsible than ever – the new, innovative heat pump technology from Viessmann makes particularly efficient use of environmental energy for heating and cooling. With a flow temperature of up to 70 °C, the Vitocal 151-A was specially developed for modernisation projects. Existing radiators can continue to be used. Underfloor heating is not essential. High energy efficiency, convenient control via app, sustainable operation and attractive design are all convincing features.

Benefits of the Vitocal 151-A

Climate Protect+++ protects the environment and the climate

The new heat pumps in the Vitocal 15x series use the "green" refrigerant R290 (propane), which is considered particularly environmentally responsible with its very low GWP100 (global warming potential) of 0.02.

Climate Protect+++ protects the environment and the climate
The Climate Protect label is based on the TEWI (total equivalent warming impact) indicator, which identifies the lifecycle efficiency of the appliance and the global warming potential of the refrigerant used.

OptiPerform –– reliable operation with maximum efficiency

The advanced heat pumps from Viessmann work with a patented hydraulic system. With Hydro AutoControl®, the heat pump is operated reliably and with maximum efficiency throughout its entire service life. The unique design not only ensures that your contractor can set up the heat pump with OptiPerform much faster and, therefore, more cost effectively. It also takes up much less space because it is up to 60 percent smaller than comparable systems.

OptiPerform – reliable operation with maximum efficiency

Service link - quick service response times

Heat pumps with a service link use wireless technology to automatically notify the trade partner of any possible faults. Completely free of charge. This eliminates unnecessary travel, as on-site servicing is quicker. Saving time and money.

Service link – for faster response time if a service is required
