Existing systems: Step by step guide

Recommendations for efficient operation of heating systems

1. Set the correct temperatures for the building (around 20°C). Higher temperatures use more energy but do not improve comfort. Install suitable control systems to maintain the correct temperature level (thermostats). Take into account that each degree over 20°C leads to 5-7% unnecessary energy waste.
2. Install zone regulation when possible in order to avoid heating of non-used zones (corridors, warehouses etc). Distribute the heat according to orientation, insulation etc. If the building is not correctly insulated, heat and money will be lost. Carefully control doors, windows and joints. Consider double glazing and seal gaps. See thermal insulatation and draught proofing.
3. In air-heating systems, a portion of the exiting air that is still warm can be recirculated, using active carbon filters to clean the air so it does not become polluted.
4. Don't forget to insulate boilers and storage tanks, as well as pipes, valves and other distribution equipment that transports the heating fluid.
5. Review your heating system periodically, paying special attention to burners. Good maintenance can save up to 5% of the total fuel consumption and reduce pollutant emissions.
