5 Ways to Instantly Reduce Your Heating Costs This Winter (Without Freezing)

Winter's coming — and with rising energy prices in Germany, it's more important than ever to take control of your heating costs. The good news: you don't have to freeze to save. Here are five practical steps you can implement this month to trim your heating bill, while staying comfortable at home.

1. Set your room temperature correctly

According to advice from Coolblue, lowering your thermostat by just 1 °C can save about 6% energy in an average German apartment. Aim for ~20-22 °C in living rooms and ~18 °C in bedrooms.

2. Heat intelligently when you're away

If you leave your flat for hours or days, there's no need to keep it at full heat. A smart or programmable thermostat can reduce heating when you're gone and raise it again before you return — saving energy without discomfort.

3. Seal drafts and check insulation

Even the best heating system can't compensate for cold drafts or poor insulation. Leaky windows, doors, or blocked radiators waste heat — and money. The German Environment Agency estimates losses of up to 20-25% from these issues.

4. Ensure radiators are efficient

Simple maintenance helps: bleed radiators so they heat efficiently, keep furniture and curtains away from them, and install reflective foil behind radiators if mounted on external walls. These small tweaks can yield savings of 8-14% according to TÜV Nord.

5. Make smart upgrades if possible

If your budget allows, consider upgrading to smart thermostatic valves or a smart thermostat. These devices let you schedule heating per room, detect open windows, and monitor consumption. Coolblue reports savings up to €300/year with the right setup.
