Heating, from Enea 10 tips and a guide to save energy


05/11/2021 – 10 rules of thumb to heat homes in the best possible way, safeguarding the environment and saving energy, especially in this period of significant price increases, and a Guide free for condominiums with the rules for a correct distribution of the costs of heating, cooling and domestic hot water.

He publishes them Enea on the occasion of the lighting, on October 15, of the heating systems in more than half of the 8 thousand Italian municipalities (climatic zone E).

Heating, i 10 practical tips

1) Perform plant maintenance. It is the first rule in terms of safety, savings and environmental protection. A system consumes and pollutes less when it is correctly adjusted, it is clean and without limescale deposits. For those who do not carry out maintenance on their system, there is a fine starting from 500 euros (Presidential Decree 74/2013).

2) Check the room temperature. Overheating the house can damage health and pockets: the legislation provides for a temperature of 20 degrees plus a tolerance of 2, but 19 degrees are more than enough to guarantee the necessary comfort. In addition, for each degree less, 5 to 10 per cent of fuel consumption is saved.

3) Pay attention to the hours of ignition. It is not advantageous to keep the heating system on day and night. In an efficient home, the heat accumulated by the structures when the system is in operation guarantees a sufficient degree of comfort even during the hours of shutdown. The maximum daily ignition time varies by law according to the 6 climatic zones into which Italy is divided: from 14 hours a day for plants in zone E (north and mountain areas) to 8 hours in zone B (coastal strips of the south Italy).

4) Install reflective panels between the wall and the radiator. It is a simple but very effective solution to limit heat loss, especially in cases where the radiator is embedded in the wall, reducing its thickness and degree of insulation. To help reduce dispersion towards the outside, a simple sheet of aluminum foil may suffice.

5) Shield the windows at night. By closing shutters and shutters or placing heavy curtains, heat loss to the outside is reduced.

6) Avoid obstacles in front of and above the radiators. Placing curtains or furniture in front of the radiators or using the radiators as a laundry dryer hinders the diffusion of heat towards the environment and causes waste. Furthermore, it only takes a few minutes to renew the air in a room, therefore, the windows should not be left open for too long as it involves unnecessary heat loss.

7) Get your home checked up. Asking a technician to carry out an energy diagnosis of the building is the first step to take to assess the state of the thermal insulation of walls and windows and the efficiency of the air conditioning systems. With the diagnosis it is possible to know the interventions to be carried out by evaluating the cost-benefit ratio. In addition to reducing the costs for heating, even up to 40%, the interventions are even more convenient if you take advantage of the tax deductions for the energy requalification of buildings, the eco-bonus that allows you to deduct from the personal income tax or IRES taxes from 50 to 85% of the costs incurred depending on the complexity of the intervention and the Superbonus, with a deduction rate of 110%.

8) Choose innovative heating systems. Since 2015, with rare exceptions, only condensing boilers can be installed. It is advisable to consider the possibility of replacing the old heat generator with a condensing one or with a high efficiency heat pump. Biomass-fired boilers and hybrid systems (condensing boiler and heat pump) are also available combined with solar thermal systems to heat the water and photovoltaic systems to produce electricity. Also for these interventions it is possible to take advantage of the tax relief.

9) Choose innovative technological solutions. It is essential to equip your system with an automatic temperature control unit capable of avoiding unnecessary peaks or sudden changes in power. The possibility of hourly, daily and weekly programming guarantees further energy savings. Home automation also promotes savings: chronothermostats, presence sensors and electronic controllers allow you to adjust the temperature of the individual rooms and the switch-on time of the heating systems even remotely via mobile phone.

10) Install the thermostatic valves. These devices are used to regulate the flow of hot water in the radiators, making it possible not to exceed the temperature set for space heating. Mandatory by law in condominiums, thermostatic valves help reduce consumption by up to 20%.
