The time comes punctually heat the house and then you realize how much gas costs. And if up to three quarters of the year it went all in all well, with the expenditure of the typical household that has decreased compared to last year for both methane and electricity, the last quarter of 2015 marks a reversal of the trend .
After the decreases recorded in recent months, the tariffs of the protected electricity and gas market have started to increase again e heat the house now it costs more. This is quite strange given that oil prices on international markets mark a decline, but the Italian situation is notoriously particular.
Consumer associations emphasize that not only the prices of raw materials weigh on the increase in electricity and gas bills, but also, excessively, taxation and system charges. To understand, the taxation on gas is equal to 35% of the costs; and the VAT is 22% because in Italy methane is still considered a luxury item. System charges are the burden of the electricity bill, with an incidence equal to 25% of the cost.
That's why, despite low oil, heat the house It costs more. And open your sky if the oil market should point upwards, which is also possible. In such an event, without immediate action on taxes and charges, the variable tariffs of the protected market for families would skyrocket.
What to do? If the price of gas and electricity does not depend on us, we can try to consume less. Without sacrificing comfort but simply eliminating waste. To help consumers heat their homes without waste and nasty surprises on their bills, the experts of the Ministry of Economic Development (in collaboration with the National Energy Efficiency Agency of ENEA) have compiled a handbook with 10 basic rules for heat the house efficiently and more conveniently. We also and above all expect an intervention on taxes and charges from the MiSE and the Government… but in the meantime we thank and pass the word.
10 basic rules for heating your home
- Plant maintenance. A well-regulated and well-maintained heating system consumes and pollutes less. Maintenance is also a question of safety and this is also why it is mandatory: anyone who does not carry out maintenance on the boiler risks a fine of no less than 500 euros (DPR 74/2013).
- Adjust the room temperature. An overheated house is bad for your health as well as for your pockets. The law allows an internal temperature of 20-22 ° C, but even 19 ° C is sufficient to ensure comfort if the air humidity is correct (check the humidity in addition to the temperature to improve the air in the house). Warning: each degree less corresponds to 5-10% savings on methane consumption for heat the house.
- Respect the hours of ignition. The maximum daily ignition time is established by law according to the 6 climatic zones into which Italy is divided. For the municipalities of band E, the most northern and coldest, excluding the Alpine municipalities, the maximum time is 14 hours per day.
- Use the chronothermostats. It's time for Energy Intelligence: The electronic devices that allow you to adjust the temperature and time of ignition are very useful. For example, to automatically turn off the system when you are not at home.
- Apply the thermostatic valves. With these valves it is possible to open and close the circulation of hot water in the radiator while maintaining the set temperature constant. Also, the valves make it possible heat the house room by room concentrating the heat in the most frequented environments.
- Reflective panels between wall and radiator. Easy to install, they are very effective in reducing heat loss to the outside. In condominiums built in the sixties you can still see radiators placed in front of the glass of the windowed walls: it's absurd, half of the heat is lost outside!
- Screen the windows at night. No one to stay in the dark during the day, but shutters and shutters at night are better to keep them closed in winter. Heavy curtains in front of the windows also reduce dispersion towards the outside, as long as they do not cover the radiators.
- Do an energy diagnosis of the house. If the building was built before 2008, it probably does not comply with the current regulations on energy saving for buildings under the new EPA, and perhaps it is not minimally isolated. It may be convenient to make an insulating thermal coat or to replace the windows with less dispersing models. Both of these interventions are facilitated with the 65% tax eco-bonus.
- Efficient heating system. If the boiler is more than 15 years old, it is worth considering its replacement. For heat the house today the condensing boiler is mandatory (unless it is physically impossible to install it), but biomass boilers, heat pumps or systems in which the boiler is fed with water preheated by a solar thermal system or a heat pump can also be considered powered by a photovoltaic system. Also for these interventions you can take advantage of the 65% eco-bonus for the energy requalification of buildings and 55% for building renovations.
- Avoid obstacles in front of and above the radiators. Never put curtains or furniture in front of the radiators or use the radiators as a tumble dryer: heat is lost and energy is wasted. Also avoid keeping the windows open for a long time for air exchange: a few minutes with the windows wide open are enough to ventilate a room.
