Lower Heating Costs: 10 Tips for Real Savings
Heating costs make up a significant portion of monthly bills. These 10 tips will help you effectively reduce consumption without sacrificing comfort.
Heating accounts for an average of 65% of energy costs in German households — that's €1,200 to €2,500 per year. With the right measures, this amount can be reduced by 20–30% without sacrificing warmth and comfort. Here are the 10 most effective levers.

These measures cost nothing and can reduce your heating bill this month.
1. Optimize Thermostat Temperature
Each degree less saves about 6% of heating costs — that may not seem like much, but it amounts to around €90 per degree with an average heating bill of €1,500. Here's a general guideline for optimal temperatures:
- Living Room: 20–21°C (68-70°F)
- Bedroom: 16–18°C (61-64°F) (cooler sleep is better)
- Kitchen: 18–20°C (64-68°F) (stove provides heat)
- Bathroom: 22–23°C (72-73°F) (but only when in use)
- Unused Rooms: 14–16°C (57-61°F) (don't turn off completely — risk of mold)
2. Short Ventilation Instead of Constant Cracking
A window constantly cracked loses as much heat per hour as it takes 2 hours to generate with heating. Short ventilation is a more efficient alternative: open wide for 5–10 minutes, then close. The walls cool down only slightly, and stale air is exchanged. Short ventilation 3–4 times a day is optimal in winter.
3. Keep Radiators Clear
A sofa directly in front of the radiator blocks up to 30% of the heat output — the heating has to run longer to achieve the same effect. The same applies to curtains hanging over the radiator and towels drying on it. Minimum distance to the radiator: 30 cm (12 inches).

4. Install Smart Thermostats
Smart thermostats like Tado, Nest, or Fritz!DECT 301 cost €40–€60 per radiator but pay for themselves in 1–2 years according to the manufacturers. They automatically adjust the temperature based on occupancy, outside temperature, and even whether you're still in bed. Tests show they save an average of 22% of heating costs compared to conventional thermostats.
You can find current deals on smart thermostats at Amazon and MediaMarkt — especially around Black Friday, there are great deals.
5. Bleed Radiators Regularly
If the top of a radiator remains cold while the bottom is warm, it has air in the system. This air prevents hot water from circulating to all areas — the radiator emits 15–30% less heat a
