Electricity bill: Place aluminum foil behind your radiators, the expert tip that works

Create your panel: Take a piece of cardboard the size of your radiator.
Cover it with aluminum foil: Carefully wrap the cardboard in aluminum foil, shiny side out, and secure it with staples or tape.
Install it: Place this panel between your radiator and the wall, leaving a small gap to allow air to circulate.

And voilà! Your radiator instantly becomes more efficient, without any additional expense.

Alternative for the less DIY-minded

If DIY isn’t your forte, don’t panic. DIY stores sell aluminum thermal insulation films, often sold in rolls. Although more expensive (around €20 to €50 for 15 meters), this option is ideal for covering multiple radiators or for those who want a ready-made solution.
