Heat pumps — systems and costs in Luxembourg at a glance
A heat pump extracts warmth from the air or the ground to heat the house — cutting the heating bill by 60 to 70% compared with an oil boiler. Systems differ mainly in their source — air-to-water, air-to-air or geothermal — and in their sizing, which the Klimabonus can fund up to half of.

Why a heat pump in 2026: the heating system that pays for itself
In Luxembourg, oil and gas are on their way out of homes. A correctly sized heat pump cuts the heating bill by 60 to 70% — and the Klimabonus can fund up to half of it.
−60 to −70% on the heating bill
Compared with an oil boiler, a heat pump halves or thirds the bill. Over the system's lifetime, that gap pays back the installation.
The Klimabonus pays up to half
The state subsidises air-to-water and geothermal systems, with a bonus if you replace an oil boiler. Your quotes arrive with the grants already deducted.
Your home gains value
The energy rating shows up directly in the sale price. A heat pump improves the energy passport — a concrete argument the day you sell.
You leave fossil fuels at your own pace
Oil boilers are being phased out in Luxembourg. Replacing now means choosing your own timing — and your grants — instead of having them imposed.
Warm in winter, cool in summer
A reversible heat pump also cools the house during heatwaves. One system, two seasons covered.

Heat pumps: your questions
How much does a heat pump cost in Luxembourg?
Between €8,000 (air-to-air) and €30,000 (air-to-water, whole house) installed, depending on the system and the property, before grants. The Klimabonus can cover up to half the cost. Your two quotes price everything, grants deducted.
Which grants can I get?
The Klimabonus scheme heavily subsidises air-to-water and geothermal systems, with a bonus for replacing an oil boiler. Our installers calculate your exact grant in the quote.
Air-to-water or geothermal?
Air-to-water suits most Luxembourg homes and is quick to install. Geothermal performs better but needs drilling. Your two installers advise you based on your property.
How many installers will contact me?
Two at most. Never 5, never 27. It is written into our contract.
Are heat pumps noisy?
Recent air-to-water models are very quiet. What matters is where the outdoor unit sits — your installers factor that into the quote.
Is it free for me?
Yes, €0. HomeUpdate is paid by the trade companies, never by homeowners.
