TOP PRODUCTS 2022: Viessmann Monobloc ASHPs

As featured in the December issue of Professional Heating & Plumbing Installer, we’re taking a look through some of the products which have caught our eye over the past 12 months.

In the spring, Viessmann announced the launch of two new monobloc air source heat pumps, the Vitocal 150-A and Vitocal 151-A – each available with outputs of 10, 13 and 16kW.

Both the wall-mounted Vitocal 150-A and the floor-standing Vitocal 151-A have a maximum flow temperature of 70°C (at an outside temperature down to -10°C), meaning that in most cases they can use existing radiators and do not require under-floor heating.

The new products use the same control platform as Viessmann’s boilers, so that they are compatible with the rest of the company’s product range, and both integrate previously separate system elements in the indoor unit (IDU), reducing installation time. Both models also feature Viessmann’s ‘Super Silent Design’. The Vitocal 151-A has an integral, 190-litre DHW cylinder.
