With 4 models to choose from, EcoForce wall-hung, gas-fired condensing water heaters are available in outputs ranging from 83 to 147 kW. Operating at seasonal efficiencies of up to 96% (Gross CV), all models feature a pre-mixed burner, which will modulate down to 20% of output and accurately matches heat output to demand. This ensures that optimum efficiency is maintained even in part load demand periods. 

EFW water heaters can be either wall or frame mounted and at only 440mm wide and 539mm deep, provide a compact, space-saving solution for commercial, industrial, and large residential buildings.
