Always condensing — heating and DHW
Modern buildings with improved insulation often place greater demand on hot water than space heating. The CoilMaster condenses in both modes, extracting maximum efficiency from every unit of gas — regardless of whether it is producing heat or hot water at any given moment.
High-volume instantaneous output — no additional storage
The CoilMaster delivers up to 1830 litres per hour of DHW at 60°C from a single floor-standing unit, without supplementary cylinder storage. Where plant room space is at a premium, this significantly reduces installation complexity and the associated capital cost.
Legionella risk eliminated
The indirect stainless steel DHW coil operates at high temperatures within the primary circuit. The high operating temperatures of both the primary and domestic circuits allow for rapid, high-volume hot water production while negating the threat of legionella.
Stainless steel throughout
Internal pipework and the Coil Fire Tube heat exchanger are both constructed from ferritic stainless steel, offering strong resistance to corrosion and thermal expansion. Self-cleaning flue ways simplify servicing and help maintain peak efficiency across the appliance's full working life.
