Electric Heating
Check that 230v supply is displayed on
the Standby Screen. The Alde boiler is
programmed to use power economically and
there are times when it may use no power at
all, even if set to 3kW.
i. Select Off, 1, 2 or 3 kW electric heating.
More power equals better performance, but
may be restricted by the current (amps) limit
on the electric hook-up.
ii. Adjust by pressing Plus or Minus button.
Max current draw from 230 V supply is 4.5
A on 1 kW, 9 A on 2 kW, 14 A on 3 kW. If
the electric supply has unstable voltage, the
amperage will also fluctuate.
