Saving on a €15,000 installation: approximately €2,100 compared to the standard rate.
Choosing the right system
By situation
- Well-insulated house: heat pump (best efficiency, lowest running costs)
- Mains gas available: condensing gas boiler (good compromise, lower upfront cost)
- Storage space available: pellet boiler (eco-friendly and economical)
- Poorly insulated house: insulate first, then choose your heating system

FAQ
How much does a heat pump cost in Luxembourg?
An air-to-water heat pump costs €12,000-20,000 including installation. After Klimabonus grants (€4,000-8,000), the net cost is typically €8,000-14,000 — competitive with gas boiler replacement.
Is annual boiler servicing mandatory in Luxembourg?
Yes. Annual servicing is legally required for all boilers in Luxembourg. A service certificate must be kept on file. Failure to comply can affect your home insurance and liability in the event of an incident.
How long does a heating system last?
Heat pumps and gas boilers typically last 15-20 years. Pellet boilers have a similar lifespan. Regular annual servicing significantly extends the life of any system.
Can a heat pump be installed in an older house?
Yes, but a minimum level of insulation is needed for it to run efficiently. If your home is poorly insulated, it is strongly recommended to insulate first — this reduces the required power (and therefore cost) of the heat pump, and maximises Klimabonus grants which can be combined for both insulation and the heat pump.
