Find a heat pump installer in Luxembourg

Compare verified heat pump installers in Luxembourg for air-to-water, geothermal and hybrid systems. A standard air-water install sits between €12 000 and €18 000, geothermal between €20 000 and €35 000 including ground loop and drilling. Klimabonus 2026 refunds up to €10 000 on air-water and €12 000 on geothermal, capped at 50 % of the invoice, when the installer is Klima-Agence accredited and the unit uses an inverter compressor. Insist on a heat-loss calculation before sizing, and get the electrical feasibility checked — a heat pump often triggers a main-fuse upgrade.

How to choose the right provider

Ranking well for a service search depends on proving useful decision support, not just naming the service. These are the checks users should be able to complete before making contact.

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.

A quote promising Klimabonus without the installer's listing number on it is either optimistic or fraudulent. Don't sign.

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.

A quote that quotes only sound pressure at 10 m distance (intentionally low) without the Lw figure is hiding the number you need for a neighbour complaint.

When to contact a provider

Replacing an old oil or gas boiler

If the boiler is over fifteen years old, heat-pump replacement with Klimabonus usually beats a like-for-like swap on ten-year total cost. Start the Klima-Agence consultation before signing anything.

Deep renovation with new insulation

A heat pump only performs when the building's heat loss is low enough. Order the thermal study first; install the pump last once walls, roof and windows are tight.

New construction with underfloor heating

In a new-build, the underfloor circuit, the heat pump and the photovoltaic array are usually scoped as one bid package. Coordinating all three with the same integrator cuts coordination overhead.

Existing heat pump running inefficiently

If your current unit cycles frequently, runs the electric backup through winter, or the room temperature lags the thermostat, the root cause is almost always undersized buffer, incorrect flow temperature setting, or a failed mixing valve. A qualified technician rebalances for €400 to €900; replacement is rarely the right first move.

What to compare in quotes

  • Heat-loss sizing, current heating emitters, insulation level, outdoor-unit placement, noise, access, and electrical capacity.
  • Appliance, buffer tank, hydraulics, controls, commissioning, subsidy/admin support, and maintenance contract separated.
  • Whether radiators, underfloor heating, boiler removal, drilling, or backup heat are included or excluded.

Luxembourg checks before you hire

Permits depend on the commune

Construction, transformation, facade, roof, demolition, and change-of-use work can require a building permit from the mayor of the commune. Interior work that does not touch structure, facade, or roof is usually lighter, but commune rules still matter.

3% VAT can apply only under conditions

Eligible housing construction or renovation work may use Luxembourg's super-reduced 3% VAT route when the home is used as a main residence and the AED conditions are met.

Check business authorisation

For regular commercial, craft, and many liberal activities in Luxembourg, ask who holds the autorisation d'etablissement and whether the quoted work matches that activity.

Ask for insurance in writing

Before work starts, get civil liability or professional insurance details in writing, especially when the provider enters your home, handles keys, or works on fixed installations.

FAQ

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.

Does a heat pump work in an older, poorly insulated house?

It can, but performance drops sharply below a minimum insulation level. Order a heat-loss calculation first. If the figure exceeds roughly 100 W/m², insulate the roof and upgrade the windows before installing — otherwise the compressor will run on electric backup at cost parity with oil.

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.

Will the outdoor unit bother my neighbours?

Modern inverter units run at 45–55 dB(A) at one metre — roughly a whisper at night. Luxembourg municipal noise rules typically cap 35 dB(A) at the property line between 22:00 and 06:00. Place the unit at least two metres from the boundary, use rubber mounts and schedule the compressor to down-modulate overnight.
