Want to cut your heating bills? As a home energy expert with years of testing efficiency hacks, I've found a simple, effective solution: aluminum foil behind your radiator.
In winter, households often consume 20-30% more heating than needed, as heat escapes into walls, curtains, and ceilings.
A sheet of aluminum foil can reflect that heat back into your living space, maximizing warmth where you need it.
Position the foil behind the radiator to repel heat toward the room's center, preventing loss to the wall.
For a clean, secure fit, apply double-sided tape to the foil and slide it into the gap between the radiator and wall—your decor stays pristine.
Avoid this if your walls are damp; the heat absorption there helps combat moisture.
Many over-rely on high settings because radiators underperform. This method lets me dial down from 6 to 3 while staying comfortably warm—it's working in my home right now.
Key Note: This works best with cast iron radiators, not electric convectors or other types.
