Example: A family with 2 children live in a house with 1 flat-screen TV, 1 di-
gital box, 1 DVD player, 1 TV games console, 2 computers, 3 stereos, 2 bulbs
in the WC, 2 bulbs in the bathroom, 4 bulbs in the kitchen, 3 bulbs outside,
a washing machine, tumble drier, fridge, freezer, oven, vacuum cleaner, en-
gine block heater = 6240 kWh domestic electricity/year.
Energy meter
Check the accommodation's energy meter regularly, preferably once a month.
This will indicate any changes in power consumption.
Newly built houses usually have twin energy meters, use the difference to
calculate your domestic electricity.
New builds
Newly built houses undergo a drying out process for a year. The house can
then consume significantly more energy than it would thereafter. After 1-2
years the heating curve should be adjusted again, as well as the heating curve
offset and the building's thermostat valves, because the heating system, as
a rule, requires a lower temperature once the drying process is complete.
