Is Viessmann Vitocal a good air source heat pump brand?
Premium German engineering with the Vitocal range using R290 to hit high flow temperatures, suiting period properties keeping their radiators. Build quality and longevity reputation near the top of the market. Viessmann Vitocal is best suited to period-property owners who want premium hardware without a full radiator re-pipe.
What is the warranty on a Viessmann Vitocal heat pump?
Viessmann Vitocal backs the unit with a 7-year warranty and the compressor with 7 years (indicative; confirm the current terms for your specific model, as accredited-installer schemes often extend them). Workmanship cover for the installation itself comes separately from your installer and should be at least 12 months. Warranty claims generally require professional installation and servicing per the manual, so keep your installation paperwork and MCS certificate.
How efficient is a Viessmann Vitocal air source heat pump?
The Vitocal 150-A 8kW carries a SCOP (seasonal coefficient of performance) of 4.4, meaning that across a heating season every 1 kWh of electricity in delivers about 4.4 kWh of heat. At Ofgem cap electricity prices (~25p/kWh) and a typical 10,000 kWh annual heat demand, that is an estimated running cost of around £570 a year, against roughly £640 to £810 for a 90%-efficient gas boiler at the 2026 cap gas rates (5.74p rising to 7.33p/kWh on 1 July 2026). Estimates, not quotes; heat-pump time-of-use tariffs can do better.
How long does a Viessmann Vitocal heat pump last?
Viessmann Vitocal warrants the unit for 7 years and the compressor for 7, and with an annual service heat pumps are generally expected to run well beyond their warranty period. Longevity depends on correct sizing (the MCS heat-loss survey), sensible siting and regular servicing. Confirm design life and extended-warranty options for your specific model with your MCS-certified installer.
