Home heating efficiency depends on insulation and system choice

Choosing an efficient home heating system requires evaluating the building's insulation before selecting equipment. Improving the building envelope—such as wall, roof, and window insulation—is more critical for reducing costs than simply upgrading a boiler or heat pump.

Heat pumps are most effective when paired with low-temperature distribution systems like underfloor heating. If a home requires very high water temperatures for comfort, the efficiency of a heat pump decreases, potentially leading to higher bills.

Pellet boilers serve as a modern biomass alternative, offering operating costs that can be up to 60% lower than natural gas in certain European regions. These automated systems use compressed wood waste to feed a combustion chamber, often achieving efficiencies exceeding 90%. Options range from small-capacity units for apartments to large silo-fed systems for houses over 150 square meters, providing varying levels of autonomy.
