(Adnkronos) – Ten tips for efficient use of heating and 10 more for “smart” energy use as Italians grapple with rising electricity and gas bills. Enea adheres to the ‘M’illumino di meno’ campaign of the Caterpillar program of Radio2, on Friday March 11, with the dissemination on its website and on social networks of the 20-point guide to save on energy consumption and reduce the costs in the invoice. “A few free gestures are enough to reduce our bills. And it is possible to obtain even greater savings with other actions such as the maintenance of the systems, the constant control and regulation of the temperature of the rooms, the replacement of energy-consuming appliances with more efficient models up to building insulation , a structural intervention that today represents zero cost for citizens, thanks to tax deductions such as the 110% Superbonus”, explains Ilaria Bertini, director of the Energy Efficiency Department of Enea.
Here is a summary of good practices to apply and mistakes to avoid by the Agency’s Energy Efficiency Department.
1 – Use energy-saving bulbs: LED technology allows great energy savings because, at the same power absorbed, it produces 5 times more light than conventional incandescent and halogen bulbs. The lifetime of a white light LED is approximately 15,000 hours; by comparing it with fluorescent bulbs (7,500 hours of operation) and halogen bulbs (750 hours), you can see the savings in terms of maintenance over time.
2 – Improve the insulation of the house: the realization of a thermal insulation of the envelope and in particular the insulation of the roof, reduce the dispersions between 40 and 50%. The lower need for thermal energy once the interventions have been carried out also makes it possible to install a less powerful and therefore less expensive boiler.
3 – Insulate the roof and ceiling: a well-insulated roof makes a difference on the energy bill by managing to contain rising heat loss.
4 – Use double glazed windows.
5 – Reduce the use of hot water: taking a bath compared to taking a shower involves four times higher water consumption. To further reduce consumption, it is important to turn off the water when soaping or when carrying out treatments such as balms or masks; additional savings can be obtained by installing aerators or flow restrictors on taps and showers.
6 – Prefer electronic devices with a higher energy class.
7 – Use power strips: on average, the television or any electronic device on standby, that is to say with the red light on, absorbs a power of 1 to 4 Watts (depending on the brand and model). If we multiply this figure by 24 hours, it appears that between 24 and 96 Wh have been consumed. This figure becomes impressive if it is multiplied by the whole year, that is to say by accumulating an unnecessary consumption estimated between 8,760 Wh and 35,040 Wh. The solution to this problem could be to combine all the plugs of the electronic devices into a power strip with a switch attached, so that you can turn them all off with a single touch if they are not in use.
8 – Do not leave the light on unnecessarily.
9 – Building renewable energy production plants: building a plant that uses renewable energy is very useful in the production of electrical or thermal energy. These systems, if properly combined with each other, can allow homes to be completely independent of external electricity and/or other fuel supplies.
10 – Perform system maintenance.
11- Check the ambient temperature.
12 – Pay attention to the times when the radiators are switched on: it is useless to keep the heating system on day and night. In an efficient house, the heat that the structures accumulate when the system is in operation guarantees a sufficient degree of comfort even during the downtime.
13 – Protect the windows at night: closing shutters and rolling shutters or putting up heavy curtains limits heat loss to the outside.
14 – Avoid obstacles in front of and above radiators and do not leave windows open for too long.
15 – Check-up of the property: the evaluation of a technician on the degree of efficiency of a property, carried out through the energy audit or the energy performance certificate (Ape) makes it possible to determine the most appropriate interventions to contain consumption and costs.
16 – Equip your installation with a thermoregulator.
17 – Use thermostatic valves.
18 – Use a heat metering system.
19 – Replace the existing boiler with a condensing boiler.
20 – Regularly defrost refrigerators and freezers.
