2 Vitopend 100-W Wall mounted gas fired boiler with high DHW convenience
By storing hot water, the gas fired combi boiler Vitopend 100-W offers a high DHW convenience. This is achieved by the combined buffer/diaphragm expansion vessel that keeps a constant store of 4 litres of heating water for DHW heating. This enables DHW to be made available within 5 seconds at the required temperature and with high consistency.The buffer effect enables the boiler to be kept at a lower standby temperature, resulting in longer burner runtimes and a lower start-up frequency. Although the Vitopend 100-W offers a high output capability, its dimensions are very compact and its operation is very quiet – ideal for the installation in the living space.
