In this review, we look into the Viessmann Vitocal 200-A air source heat pump and compare its specs and features to other models on the market.
Viessmann’s Vitocal 200-A is a compact and efficient air source heat pump. It comes in 2 models, one which is heating only, and one which provides heating and active cooling.
In this review, we look into the specs, features, and pros and cons of this German-manufactured heat pump so you can decide whether it’s the right fit for your home.
The Viessmann Vitocal 200-A is a monobloc air source heat pump. It’s available in two models, one for heating only and one for heating and cooling, and consists of an indoor wall-mounted unit and an outdoor unit.
The Vitocal 200-A is available in outputs ranging from 4kW to 11.8kW, but you can also cascade up to 5 heat pumps to increase their power outputs to suit larger homes. All but 2 models in the series hold an A+++ efficiency rating.
It can be installed as a retrofit or be integrated into both new and existing heating systems. You can also connect this heat pump to solar panels for an environmentally friendly and economical home energy system.
While it has a minimum operating temperature maximum of −10°C, but it can be integrated with existing heating solutions to compensate for when temperatures drop below that. The Vitocal 200-A can also be connected to solar panels with ease.
The indoor unit is very compact so it is suitable for smaller households. It is sleek and attractive, and the monobloc design means all components are housed internally, making maintenance very simple.
The outdoor unit’s exceptionally quiet operating sound level (just 35dBA) makes it appropriate for terraced houses or built-up areas too. The fan is sound-optimised and uses intelligent speed control to further reduce airborne noise.
Homeowners have the option of purchasing a maintenance plan from Viessmann to keep their heat pump in optimal condition at all times, and it comes with a generous 7-year warranty on parts as standard.
Installation is quick and simple. The system features water-filled hydraulic lines running to the outdoor unit, meaning your installer does not need an F-Gas certification.
The Vitocal 200-A comes with pre-assembled components and accessories that easily fit together, meaning installation is very quick.
You can enable wi-fi control and monitoring by connecting the Vitoconnect web interface accessory to your Vitocal 200-A heat pump and using the free ViCare app.
If you are looking for a more powerful air source heat pump, we’d recommend looking into the Vaillant flexoTHERM, which combined with the aroCOLLECT can reach a power output up to 19kW.
If you want to stick with the Viessmann brand, the Vitocal 100-A air source heat pump is cheaper than the 200-A and slightly more compact. However, it is less suitable for low temperatures as it only operates at 100 per cent down to temperatures of −5°C.
For very cold climates, we would suggest the Daikin Altherma range, which has been designed to handle temperatures of −28°C as well as cold and wet weather conditions.
The Viessmann Vitocal 200-A heating-only heat pump is currently on sale at a price ranging between £5,650 and 9,500, making it one of the most expensive heat pumps on the market. For the heating and cooling model, you can expect to pay between £6,000 and £9,750.
As of October 2025, Viessmann is rated 4.4 stars out of 5 on Trustpilot, making it an “Excellent” company by the platform’s standards. Customers report being satisfied with their Viessmann products, mainly with their boilers, but also with their experience of installation and after-sales care. There are some occasional complaints about durability and servicing, but these seem annecdotal.
“From my first enquiry to Viessmann for the name of their nearest accredited installer, to the final switch on of my new 151A air source heat pump, the whole experience has been simple and stress free. Now the installation is complete and I am delighted with the quality, quiet and running costs.”
“I had read and reviews for heat pumps that it was very important that you chose the right installer and the problems arose when the engineer who installed your heat pump inexperienced. I did get three quotations one from Octopus and a couple more from other engineers including Heat Geeks. The installation firm(Libtek) that I employed recommended Viessmann and I must say that they could not have recommended a better heat pump.”
With an A+++ energy efficiency rating, a maximum 7-year warranty and an attractive design, there’s a lot to like about this German-engineered heat pump.
The monobloc design is well-suited to smaller homes where outdoor and indoor space is limited. The units are very easy and quick to install, saving you money on installation and reducing disruption to your home.
If you live in a particularly cold climate, this heat pump doesn’t compare to alternatives like the Daikin Altherma 3 range. However, a minimum operating temperature of −10°C should be suitable for most homes in the UK.
The Viessmann Vitocal 200-A is not the cheapest system by far, but it’s efficient enough to justify the spending in the long run.
We considered several factors when reviewing the Vitocal 200-A monobloc air source heat pump, including the following weighted criteria: design (20 per cent), durability (20 per cent), efficiency (25 per cent), performance (25 per cent), and guarantee options (10 per cent). We also compared the Vitocal 200-A heat pump with some of the best outdoor heating systems and air source heat pumps in the UK in terms of both performance and price.
