Stiebel Eltron is a German manufacturer established in 1924, specialising in heating, hot water and renewable energy technology.<\/p>\n

Its HPA-O Plus range is designed to provide efficient heating and hot water for a variety of properties, including existing homes and new builds.<\/p>\n

The range uses the natural refrigerant R290 and can deliver heating flow temperatures of up to 75\u00b0C, making it suitable for consideration in properties with radiators as well as underfloor heating.<\/p>\n

The HPA-O Plus range also offers optional cooling functionality and integration with solar PV systems, subject to the overall system design.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
