Outdoor unit
Outside is the heat pump. This extracts heat
from the air, even below 0°C and uses this heat
to heat the water passing through the central
heating and hot water cylinder.
The outdoor unit pulls in air from the rear,
extracts the heat in the air, and blows the cooled
air out the front. This is done automatically,
and there is no need to set or adjust it.
If the rear of the outdoor unit gets clogged
up with leaves or debris, the efficiency of your
heating system can be reduced, this should be
checked regularly and cleaned with a soft brush.
Similarly, don’t block the front of the unit up by
leaning anything against it.
Cylinder
Hot water is stored in a cylinder. To ensure low
running costs the cylinder is normally set to heat
to 50°C. Your system is set up to heat the water
in the cylinder at the time when it is cheapest.
If you have Economy 7 this will be during
off-peak periods. If not, it will be during the day
when the air temperature is higher. The cylinder
is being heated when the symbol is shown on
the Daikin Altherma controller. Once a week the
water in the cylinder is heated to 60°C to ensure
the cylinder remains free from bacteria.
