Environmental

11.1 Energy Saving

Tips on saving energy:
Do not cover radiators. Do not hang curtains in front of radiators.
Install reflective panels behind the radiators to prevent heat losses.
Insulate the pipes in rooms that are not heated (cellars and lofts).
Install loft insulation & double glazing.
Use draught excluders where necessary.
Upgrade any older external controls.
Turn down room thermostats by 1°C
Turn off radiators in rooms not in use.
Do not run hot (or cold) water pointlessly.
Fit a water-saving shower head to save up to 40 % energy.
Take showers rather than baths. A bath consumes twice as much water and energy.

11.2 Room Thermostats and Settings

Various models of room thermostats are available. The thermostat type and setting affect the total energy consumption.
Afew tips:
Fully opening or closing thermostatic radiator valves result in unwanted temperature fluctuations. Turn the thermostat knob or valve higher or lower in small steps.
Lower the thermostat to approximately 20°C. This reduces heating costs and energy consumption.
When rooms are to be aired, lower the thermostat well in advance.
When setting thermostats or programmers take account of days when nobody will be in and of holidays.
