Vitopend 100-W_WHKB_GB.qxp - Viessmann

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.
