Use wherever oil / gas installations are impracticable or undesirable, e.g. rural areas, high rise, listed buildings and bed-sits or as an alternative to expensive fuels e.g. LPG. The units will provide central heating only (using normal wet system and/or underfloor) or central heating and hot water (via a storage tank). Boiler includes pump, auto-air vent, expansion vessel and pressure gauge within a compact casing. 700mm high x 420mm wide x 285mm deep.A very high efficiency rating is achieved through 6 stage heating using a single copper heat exchanger. End users can easily control the system (flow rate and Kw output) from the touch pad control panel. The system also has a ‘fault diagnosis’ function and will display fault codes on the control panel should the unit break down. Operating temperature is adjustable from 40-85°C.
