Wolf CGW-20/120, 3-stupňové čerpadlo
Code: 8611409Z17Product detailed description
Wolf CGW-20/120 gas-fired wall hung condensing boiler with storage water heater with precise water stratification (stratification tank)
- a hanging gas condensing boiler with minimal space requirements
- ideal for economical heating or efficient water heating
- peak condensing technology ensures high savings (maximally efficient in condensing - up to 110% efficiency), modulating burner achieving extremely low combustion pollutants
- varieties with modulating output from 3.2 to 50 kW
- clean and balanced design adapts to any space
The compact CGW-20/120 modular design consists of a wall-hung condensing boiler with plate heat exchanger and a TOP-flex stainless steel hot water tank. In the 50 litre storage tank, a hot and cold water distribution system "Turbostop" is integrated to dampen the swirling of the water and achieve perfect temperature layering. The radial direction of the water flow in the tank allows even filling and draining and therefore a comfortable supply of hot water at a constant temperature. The performance parameters correspond to those of a traditional water heater with a capacity of 120 or 140 l, the hot water supply (40 °C) at peak withdrawal of 10 min is 150 or 171 l (depending on the boiler output).
