Vaillant’s commercial boiler offering

Vaillant, commercial boiler, wall hung

Designed for commercial systems, Vaillant’s ecoTEC high-efficiency condensing wall-hung boilers are available with outputs of 44 and 65 kW. Each model has a fully modulating Class 5 low-NOx burner and fan. The 125 mm-diameter flues can run horizontally for 18 m and vertically for 21 m. There is an optional 125 mm stainless-steel facade kit.

Both boilers have stainless-steel heat exchangers and newly developed hydraulic connections and isolating valves. A sensor monitors water flow through the boiler. There is an air separator with auto air vent and filter for bleeding the system and filtering fine particles.

Both models have built-in 2-stage frost protection, shunt pump with 8 m head and a sensor to monitor system pressure via diagnostics.

For easy service and repair, there is a comprehensive display for boiler status and diagnostics. Maintenance is also simplified by there being a single electronic circuit board and a flue-gas analysis point.
