Vaillant Arostor 200L Domestic Hot Water Heat Pump 0010031862

Incredibly efficient and sustainable, aroSTOR uses thermal energy to heat hot water collected via an external air duct or it can be recycled hot air from within the room where it’s installed. The only other energy needed is the electricity to run the appliance. aroSTOR heat pumps use only R290 natural refrigerant, which is used widely in household appliances such as domestic fridge freezers. With R290, aroSTOR gives excellent performance for water heating as it can deliver 60° in the cylinder without any need for a backup heater, whilst still providing strong efficiency levels.
