TIP: In a good summer, for example, lower
the desired temperature on the control panel
to around 10 °C. The central heating will not
circulate (unless the temperature drops to
10 °C), but you can still control hot water.

1. Hot Water Ignore. Volume bar empty.
No attempt is made to heat hot water
specifically. This saves energy when the
fresh water is drained down.
2. Hot Water Normal. Volume bar half-full. Hot
water is heated to greater than 50 °C. NB: If
Circulation Pump is set to Continuous, this
option will not be available.
3. Hot Water Boost. Volume bar full. Central
heating circulation is disabled for 30 mins.
Hot water is heated to greater than 65 °C.
After 30 mins the system reverts to Hot
Water Normal.

when it may use no power at all, even if set to
3 kW.

The Alde boiler is hard-wired to use power
economically. The gas burner has two stages,
shifting dynamically between low or full flame.
There are times when it may use no power at
all, even if gas heating is selected.
