Find a heat pump installer in Luxembourg

Give the installer the property type, approximate heated area, age of the building, known insulation work and the heating system you use now. Say whether you have radiators, underfloor heating or both, and whether the home is occupied during the planned works. Photos of the boiler room, electrical board and possible outdoor-unit location can help frame the first conversation. They do not replace a site survey.

Ask how the installer will assess heat demand and the temperature your existing emitters need. Discuss noise, access for installation, condensate drainage and how the outdoor unit affects neighbours or shared spaces. If the proposal assumes insulation or radiator changes, ask for those dependencies in writing. A model and capacity chosen without looking at the building are not a reliable basis for comparing quotes.

Check whether each quote includes removal of the old equipment, the indoor and outdoor units, hydraulic connections, electrical changes, controls, commissioning and handover. Ask who coordinates any additional trade and who handles defects after installation. Compare warranties and maintenance terms separately from the equipment price. If one offer excludes a necessary task, ask for a revised written scope before comparing totals.

Ask for the survey date, expected start, time without heating and any work that must happen first. Discuss grant and tax assumptions with the installer, but verify current eligibility and application steps with the relevant official programme before signing. Do not treat an advertised subsidy or an online estimate as a guaranteed reduction of your final invoice.

The Klimabonus 2026 rules set technical conditions the quote should already reflect: a minimum efficiency (COP) for the chosen technology, electricity and heat meters, hydraulic balancing, a noise limit for an outdoor unit backed by an acoustic assessment before installation, and a reception request to the Chambre des métiers within one month of commissioning. The amount depends on the technology, the order and invoice dates and whether a fossil boiler or direct electric heating is replaced. The application is normally filed after the works, so keep the dated order, the paid invoices and the installer’s technical sheet.

A short brief with your building details, photos, preferred timing and questions lets each installer decide whether the job fits their work. Ask them to identify missing information and offer a site visit before a binding price. Keep the same brief for every provider so the differences in scope, assumptions and aftercare remain visible.
