Atag has announced a range of six “A” Series boilers, with heating outputs from 4.4kW to 30.9kW
All are SEDBUK Class A-rated, with ultra low carbon monoxide and nitrogen oxides emissions. They are available as system and open vent models or as a high-efficiency 32kW output Eco combi version, the E325 EC. This delivers higher domestic hot water outputs, up to 18.8 litres a minute, through the inclusion of an in-built pre-heat heat exchanger fitted in the flue outlet.
The unit uses the company’s stainless steel heat exchanger and has a choice of flue options that includes concentric, twin and flexible liner versions. Management centres with sensors are designed to ensure that these models operate at maximum efficiency at all times. The pre-mix burner technology ensure seamless modulation while operating.
