Heating accounts for 75% of your home's gas usage. As energy efficiency experts with years of experience helping households cut bills, we recommend optimizing your heating system. Follow these proven strategies to save up to €1,500 annually on gas costs.
Gas dominates energy expenses, especially during cold months when heating runs constantly—now even more so with widespread remote work. While a cozy blanket helps, smarter habits deliver real savings without sacrificing comfort.

Implement the tips below to easily save €1,500 a year on heating. Redirect those savings toward sustainability upgrades like better insulation.
Avoid heating adjacent rooms or propping doors open to warm the bedroom—it forces radiators to overwork. A chilly, poorly insulated bedroom risks condensation, wall damage, and mold growth.
Recommended temperatures by room:
Living room: 20–22°C
Bathroom: 20–23°C
Children's room: 20–23°C
Bedroom: 15–19°C
Kitchen: 18–19°C
Office/study: 18–20°C (lower for complex tasks, higher for creative work)
Floor: 15–19°C
Keep furniture and curtains clear of radiators for even heat distribution. Poorly insulated walls behind them waste energy—install radiator reflector foil to bounce heat back into the room.
Short bursts of cross-ventilation (5 minutes, several times daily) beat long sessions. Turn off radiators while airing. Condensation on windows? Ventilate immediately to curb mold and excess humidity.
If rooms stay cold despite higher settings, air trapped in radiators is likely the culprit. Bleed them regularly—it's simple DIY. See the video instructions below for guidance.
Dropping your thermostat 1°C (e.g., from 22°C to 21°C) saves over €100 yearly. A small change with major impact.
Heavy curtains block drafts from uninsulated walls, but position them above radiators to avoid trapping heat.
Don't drop below 18°C overnight—reheating a cold house costs more than maintaining steady warmth.
Schedule yearly boiler servicing and cleaning for peak efficiency. Replace every 10–12 years. Use heating savings to fund this.
Set your boiler to 60°C instead of 80°C for better efficiency, lower gas/CO2 use, and up to €1,200 lifetime savings—without losing comfort.
Upfront cost, lifelong payoff: Insulated glass cuts heating by 40%. Check ISDE subsidies. Insulate facades too.
A small investment in fans circulates heat faster, reducing runtime.
Comfortable and child-friendly, but maintain steady temperatures with heat-conductive flooring like tiles. Avoid frequent on/off cycles.
Trees and hedges create a wind barrier, slashing energy use by up to 9%.
High heat dries air, irritating mucous membranes and aiding viruses. Aim for 50% humidity:
