ENERGY EFFICIENCY AND THE ENVIRONMENT
Home energy use is currently responsible for more than ¼ of the total carbon emissions which contribute to climate
change. Heating and hot water systems based on boilers account for 2/3 of this figure, so it is important to
understand how controls can help to maximize energy efficiency while maintaining comfort.
DT92 temperature controls should be used in conjunction with appropriate time controls.
In order to save energy the following general points should be observed:
1. Ensure the system contains a room temperature thermostat and a hot water temperature thermostat (except for
Combi boiler systems), and that both are set to appropriate temperature levels.
2. Programme the heating and hot water to be off when the house is not occupied. If possible frost damage to any
exposed pipework is a concern, it is advisable to fit a frost protection thermostat or system. Honeywell can advise
on this.
3. It is normal to have the heating system switched off, or set-back at night when heating is not required.
4. Think about how domestic hot water is used. In a storage system, it is not necessary to have this switched on all
the time, even when the house is occupied.
5. Do not programme excessive heatup times for the central heating. If the occupier is out of the house, or still in
bed, much of this heating would be unnecessary.
6. In the evening, when the house is up to temperature, it is often possible to switch the heating off up to an hour
before going to bed, without any noticeable reduction in comfort.
