5 keys to protecting your home from the cold and saving energy



  • Rising energy prices are reducing household energy consumption

  • By repairing at home, you can achieve energy savings

Energy can be saved at home. By following a few simple instructions you’ll be done with no works requiredAchieving homes that are less dependent on energy without compromising the thermal comfort needed to weather the winter months can be within our reach by applying a few simple tips.

However, one must be aware of this These are small improvement measures that are performed immediately and without the need for specialized laborbut if the goal is to achieve high energy savings and to improve the comfort and health of our home, the best option will always be to carry out a comprehensive and coherent rehabilitation that culminates in a rehabilitation certificate.

What five keys protect the house from the cold?

Insulate the staircase.

Roller blind boxes are usually one of the weak points when it comes to protecting homes from the cold, because they hardly separate the house from the cold outside and favor drafts. On these items you can save quickly, easily and economically: put an insulating board and use airtight tapes. Energy savings depend on the size of the box, the insulation material used and its thickness.

Improved glazing with insulating sheets

Windows usually have the highest heat loss in the entire house. It is clear that a huge amount of heat is lost with the old single-glazed windows, but even with double glazing (without special coating) it is also possible to save a lot of energy. One way to achieve this is to create additional air volume by placing an insulating sheet in front of the glass that can be purchased at any DIY store and is simple and inexpensive to install with double-sided tape.

Isolation of radiator outlets

It is also possible to quickly save a lot of energy and money by placing a heat-insulating sheet on the wall directly behind the radiators, which, more often than not, is built into the holes where the wall separating it from the outside is thinner. To insulate the radiator, aluminum sheets can be used as lining. In the case of an uninsulated wall in an older building, heat loss decreases by about 40%.

Insulate hot pipes

Visible pipes through which hot water circulates are best insulated so as not to lose heat. Pipe insulation can be purchased at any home improvement store or online: it can be polyethylene (PE) insulation, which is cheap and easy to work with, but you can also use mineral fiber insulation with a sheet of aluminum foil. The insulation should be as thick as possible and it is important to seal all joints tightly afterwards so that hot air does not pass between the insulation and the pipe. The savings depend on the thickness of the pipe insulation, the temperature difference between the pipe and the air and, of course, the number of meters insulated.

Reduce room temperature

The easiest way to use less heating energy is to maintain a lower room temperature, which can be done without much loss of comfort. For example, by lowering the temperature in an old building by 2 degrees, approximately 50 kilowatt-hours can be saved per square meter of living space. It is also an option to turn off the heating completely in those rooms that are not being used. On the other hand, having programmable thermostatic valves is very useful, especially if they can also learn routines, like automatically lowering the temperature when a window is opened or activating it when it detects we’ve come home because our smartphone is connected. for Wi-Fi.

Turn off the heat?

The question is often asked whether it is worth turning off the heating at night, since the next morning more energy is required to heat the room again. And the answer is that Yes it works: Reheating a room always requires less energy than uninterrupted heating. Finally, especially in unheated rooms, adequate ventilation must be ensured. Otherwise, mold can grow, especially in the corners. Cold air can absorb much less moisture. The best of course is to have good thermal insulation everywhere and to have a ventilation system.
