Viessmann also provides the right system for retrofitting of existing condensing boilers using free ambient heat: split air/water heat pump Vitocal 250-S for combination with a wall-mounted or freestanding condensing boiler.
Supplementing a heating system for gas or oil with a heating system is ideal. Not just to be future-safe, but also to be environmentally friendly. On the one hand, you therefore use free ambient heat. On the other hand, the heating system can be operated so that the lowest heating costs are always achieved when there are fluctuating energy prices.
Choose economy – and future-safety
Heating systems with an already existing oil or gas condensing boiler up to an output of 30 kW can be retrofitted with Vitocal 250-S. The Hybrid Pro Control energy manager controls the efficiency of the complete system. Depending on the reference variable selected and according to the current energy costs, either the condensing boiler or the split air/water heat pump provides the heating.
Heat and cool with one system
If the heat pump does the heating, the outdoor unit withdraws the heat contained in the air and brings it to a flow temperature of 55 °C by the heat pump process. But the heat pump can do a lot more. For a high level of living comfort on a hot summer’s day, operation of the heat pump can be reversed. Living areas can then be kept comfortable cool. Invertercontrolled compressors and an electronic expansion valve in the refrigeration circuit also ensure a high level of efficiency here.
