General
The Energysaver Combi 2 can provide room heating as part of
a central heating system, and domestic hot water direct from
the cold water supply. Instantaneous domestic hot water is
available from a small integral hot water storage vessel, so
additional secondary storage is not required. The central heating
water temperature and domestic hot water temperature can
both be adjusted on the boiler.
Once the controls are set the boiler operates automatically.
When there is no heating or hot water demand the burner may
operate very occasionally to maintain the temperature of the
hot water in the storage vessel at the required level. If there is
no heating demand for 24 hours then the pump and 3-way valve
will be operated to prevent them sticking. A frost protection
program is also included.
Please read these instructions and follow them carefully for the
safe and economical use of your boiler.
