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 broadcast on its website and on the social networks of the 20-point guide to saving on energy consumption and reducing costs in the bill. “It only takes a few cost-free gestures to reduce our bills. And even greater savings can be obtained with other actions such as system maintenance, constant monitoring and regulation of the ambient temperature, replacement of energy -from intensive appliances with more efficient models to the insulation of buildings, a structural intervention that today is free of charge for the citizen, thanks to tax deductions such as the 110% Superbonus”, explains does he 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 light bulbs: LED technology allows great energy savings because, with the same absorbed power, it produces 5 times more light than traditional 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 the difference on the energy bill by managing to contain rising heat losses.
4 – Use double glazed windowsthe.
5 – Reduce hot water consumption: Taking a bath compared to taking a shower involves four times more 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 higher energy class electronic devices.
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 – Don’t leave the light on unnecessarily.
9 – Build renewable energy production plants: the construction of a plant that uses renewable energies 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.
ten – Perform system maintenance.
11- Check room temperature.
12 – Pay attention to the hours of ignition of the radiators: 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-Sclose the windows at night: closing shutters and blinds or putting up heavy curtains can reduce heat loss to the outside.
14 – Avoid obstacles in front of and above radiators and do not leave windows open for too long.
15 – Take stock of the property: the evaluation of a technician on the degree of efficiency of a good, carried out through the energy diagnosis 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 measurement system.
19 – Replace the existing boiler with a condensing boilerAnd.
20 – Regularly defrost refrigerators and freezers.
