Most installers can respond within a week to assess your needs. Nearby communes like Mamer, Koerich, and Habscht are also covered, so you have options.

What's included

• Air-to-water heat pump installation
• Geothermal (ground-source) heat pump
• Hybrid gas/heat-pump system
• Underfloor heating upgrade for heat-pump use
• Annual maintenance and refrigerant check
• Klimabonus subsidy filing

How to choose

• Klima-Agence accreditation — Klimabonus is only unlocked by installers on the Klima-Agence register. Confirm the listing and the autorisation d'établissement before any deposit.
• Heat-loss calculation in writing — An installer who proposes a heat-pump size without a written heat-loss calculation is guessing. A correctly-sized unit runs quieter, lasts longer and qualifies more cleanly for Klimabonus.
• Right system type for your building — Air-water suits well-insulated detached and semi-detached houses with outdoor space. Geothermal fits larger plots and high annual heat demand where the drilling payback (12 to 15 years longer than air-water) is justified by stable ground-loop COP. Hybrid gas/heat-pump makes sense for older urban townhouses awaiting insulation upgrades — the gas burner covers the coldest hours.
• Noise class and outdoor-unit placement — Ask for the sound-power level (Lw) in dB(A) from the datasheet, not just the perceived sound-pressure number. Premium air-water units sit at Lw 52 to 58 dB(A); anything above 62 dB(A) triggers neighbour complaints in Luxembourg's typical lot spacing. Confirm the unit can run in silent mode overnight without a performance penalty.
• SCOP and COP ratings disclosed — The Seasonal Coefficient of Performance (SCOP) at 35 °C flow temperature is the single most useful efficiency number for a Luxembourg climate. Target SCOP 4.5+ for air-water; 4.8+ for geothermal. A unit with SCOP below 4.0 fails Klimabonus eligibility on most 2026 brackets.
• Existing radiator and emitter compatibility — Heat pumps work best at low flow temperature — 35 °C for underfloor heating, 45 °C for oversized radiators, 55 °C the practical ceiling. Your installer should measure the largest radiator in the coldest room and confirm it can hold the design indoor temperature at those flow temperatures. Undersized radiators mean either a partial swap or staying on high-temperature mode (lower SCOP, higher bills).
• Installer certification beyond Klima-Agence — Ask specifically for (a) the Klima-Agence register entry, (b) the manufacturer's official partner status (Viessmann Pro, Daikin Altherma Pro, Stiebel Eltron Pro, etc.), and (c) the F-gas personal certificate for the named technician. The three together predict a quality commissioning; any one missing is a risk flag.

Frequently asked questions

• How much does it cost to install a heat pump?

  The cost for an air-to-water heat pump installation typically ranges from 12,000 to 18,000 EUR. For geothermal systems, you might be looking at 20,000 to 35,000 EUR. Remember, you could qualify for the Klimabonus 2026 refund, which can help reduce these costs.

• Do you cover nearby areas as well?

  Yes, we cover nearby communes like Mamer, Koerich, and Habscht. So, if you’re in those areas, you can find the same reliable heat pump installers here.

• How does a heat pump perform in Luxembourg winters?

  Luxembourg winters rarely drop below -10 °C and sit mostly in the -2 to +8 °C band where modern inverter-driven air-water units run at COP 3.0 to 3.5. Modern units are rated down to -20 °C and maintain 60 to 70 % of nominal output at -7 °C. The electric backup typically fires for only 50 to 120 hours a year and can be capped to protect the bill.

• Will I need to upgrade my electrical panel?

  Often yes. A heat pump adds 2 to 4 kW of continuous draw and typically needs a dedicated circuit. If your main fuse is 40 A or less, expect a €1 200 to €2 500 panel upgrade plus Creos paperwork. Ask the heat-pump installer to coordinate with a licensed electrician on the same schedule.

• How much does a heat pump cost installed in Luxembourg?

  Air-water heat pumps run €12 000 to €18 000 installed. Geothermal sits between €20 000 and €35 000 including drilling. Klimabonus 2026 can refund €10 000 on air-water and €12 000 on geothermal, bringing net cost to roughly €6 000–9 000 and €10 000–23 000 respectively. Condition: the installer must be Klima-Agence registered.
