Product detailed description

Wolf CGW-20/120 wall-mounted gas condensing boiler with a storage water heater with precise water stratification (stratified cylinder)

The boiler has a built-in 50-litre cylinder with a unique water stratification system. The performance parameters of this system correspond to those of a traditional water heater with a volume of 120 or 140 l respectively.

wall-mounted gas condensing boiler with minimal space requirements
ideal for economical heating and efficient hot water production
state-of-the-art condensing technology ensures high savings (most efficient during condensation - efficiency up to 110%), modulating burner achieving extremely low levels of combustion pollutants
variants with modulated output from 3.2 to 50 kW
clean and balanced design that adapts to any space

The compact CGW-20/120 unit of modular design consists of a wall-mounted condensing boiler with a plate heat exchanger and a TOP-flex stainless steel hot water cylinder. The 50 l cylinder incorporates a hot and cold water distribution system "Turbostop" to dampen water turbulence and achieve perfect temperature stratification. Radial guidance of the water flow in the cylinder ensures even filling and draining, providing a comfortable supply of hot water at a constant temperature. The performance parameters correspond to those of a traditional water heater with a volume of 120 or 140 l respectively, the hot water delivery (40 °C) during a 10-minute peak draw-off is 150 or 171 l respectively (depending on boiler output).
