1.2.11 Cleaning the radiator surfaces

1.2.11 Cleaning the radiator surfaces Description When the radiator heats up, it causes the air around it to rise as it is heated, and this draws up dusty air from the floors. As the dust sticks on the radiators, it acts like a layer of insulation, which reduces the heat transfer efficiency [...]

1.2.13 Installation of a programmable thermostat

1.2.13 Installation of a programmable thermostate   Description A programmable thermostat offers pre-programmed settings to regulate the building's temperature. Programmable thermostats can store multiple daily settings (six or more temperature settings a day) that can be manually overridden without affecting the rest of the daily or weekly program. [...]

1.2.14 Purge radiators at the beginning of the heating season

1.2.14 Purge radiators at the beginning of the heating season Description One of the most common causes of poor performance of a hot water radiator is air trapped in the system. Over time, the repeated heating and then cooling back down of the water in the system causes air to be released [...]

1.2.15 Use ceiling fans instead of air conditioning when possible

1.2.15 Use ceiling fans instead of air conditioning when possible Description Fans can make feel 3 to 8 degrees cooler, allowing dialling the AC to a higher temperature with no reduction in comfort. In temperate climates, or during moderately hot weather, ceiling fans may allow to avoid using the air conditioner altogether. [...]

1.2.16 Relocate thermostats to appropriate areas

1.2.16 Relocate thermostats to appropriate areas   Description To operate properly, a thermostat must be located on an interior wall away from direct sunlight, drafts, doorways, skylights, and windows. It should be located where natural room air currents (warm air rising, cool air sinking) occur. Furniture will block natural air movement, so [...]

1.2.17 Avoid using personal heaters in air-conditioned spaces

1.2.17 Avoid using personal heaters in air-conditioned spaces Description Generally, these types of heaters are inefficient, ineffective, and in some cases, unsafe. If occupants are in an air conditioned space (or one that is centrally heated) and find conditions a little chilly, they should not resort to personal heaters. The air-conditioning system [...]

1.2.24 Installation of thermostatic radiator valves

1.2.24 Installation of thermostatic radiator valves Description These elements open and close automatically the flow of hot water in radiators and fancoils, depending on the temperature selected by the user. To install thermostatic valves, the heating circuit should be leaked out and the shut-off valve should be replaced by a thermostatic valve. [...]

1.3.1 Lower the DHW temperature set-point

1.1.3 Lower the DHW temperature set-point Description Water should not be overheated more than necessary (each 10°C rise in DHW temperature increases the energy consumption by around 15%). To save energy, it is recommended to adjust the thermostat of DHW at 60°C (this temperature should not be reduced to avoid problems of [...]
