Viessmann UK’s managing director, Graham Russell, said: “The Vitocal 100-A is a new, environmentally-responsible heating option that is as simple to retrofit to existing homes as it is to specify for new builds. Viessmann is serious about offering a quality product in this volume sector of the market and therefore the Vitocal 100-A is price-competitive with equivalent standard monobloc air source heat pumps from other leading manufacturers.”
The Vitocal 100-A is a fully integrated outdoor unit that does not require a complementary indoor unit. The monobloc design means installers are not required to work on, or connect any, refrigerant- carrying parts; therefore, a refrigerant certificate is not required. R32 refrigerant, which has a lower global warming potential than other conventional refrigerants, is used. Six versions of the heat pump are available, with outputs ranging from 6 to 16 kW.
Where a greater output heating system is needed, such as in larger buildings, Vitocal 100-A units can be arranged in a cascade system of up to seven heat pumps. The heat pump can be installed to work in conjunction with an indoor-located, space-saving combi cylinder, which combines a 250-litre heating water buffer cylinder and 50-litre DHW cylinder, or with an outdoor-located plinth-style horizontal buffer store for additional space-saving inside the home. The Vitocal 100-A heat pump achieves 60 C temperature at -5 C outside temperature and has a COP (coefficient of performance) of up to 4.9 (A7/W35). The Vitocal 100-A can be operated directly with its built-in control unit, which is easy to use and has a plain text display.
The Vitocal 100-A is available now in UK merchants.
