Wall Hung Boilers


The A1K appliances are wall hung condensing boilers designed for heating purposes.

Available as 50kw or 100kw appliance with up to 1:20 modulation, they provide unrivalled flexibility and performance from a small footprint. 

The A1K range features integrated pump/s with PWM control which works in conjunction with the PCB, fan and burner to control the ΔT and maximise efficiency.

These appliances can be electronically cascaded to meet the required demand (up to 800kW).

With multiple installation options for internal & external applications, the A1K series is the perfect solution for purposes such as underfloor heating, pool/spa heating, HVAC applications and DHW via an Aleabrax heat exchange tank.
