Suitable for indoor or outdoor installation, the Vitocal 350-A is ideal for modernisation projects. It can be used in older systems with radiators and it supports cascade function for up to five air source heat pumps.
The Vitocal 350-A is the first air/water heat pump with digital scroll technology and an electronic bi-flow expansion valve. This means it achieves an extremely high Coefficient of Performance of 3.5 (air 2°C / water 35°C) and therefore high seasonal performance factors too.
What's more, it accounts for the particularly reliable heat supply of the Vitocal 350-A, as well as providing significantly lower running costs.
The Vitocal 350-A air source heat pump is designed to catch the eye. It is installed in the garden and utilises the free heat available in the ambient air. The appliance is specially designed for modernising detached houses.The Vitocal 350-A is very quiet, even in standard mode. At night the fan noise is further reduced by a low speed setting. Power from a photovoltaic system on site can be used to run its electrical components, thus reducing the already low operating costs.
The Vitocal 350‑A is capable of reversed operation to provide cooling during the warmer months.When high temperatures occur in summer, convectors or surface cooling systems make the interior feel pleasantly cool.
