Quote: air-to-water heat pump
E.g.: 12 kW air-to-water heat pump paired with existing underfloor heating
An air-to-water heat pump transfers heat from outdoor air to a water-based heating circuit. Describe building, insulation, radiators or underfloor heating, consumption and hot-water needs. Identify planned insulation and possible locations: these affect equipment selection and adaptations.
Establish heating demand
Klima-Agence structures design around building, heat load and emitters. Request assumptions, calculation method and condition after planned work. Do not automatically copy old boiler power or use a standard area-based rating.
Check radiators and hot water
Existing radiators do not rule out a heat pump. Have room-by-room capacity at the planned water temperature, hydraulics and adaptations checked. Describe hot-water use and storage; space heating alone does not size that function.
Compare cold-weather operation
Request available output and efficiency at project outdoor and water temperatures, plus defrosting and planned backup heat. A test-point COP is not annual bill savings. Separate compressor, auxiliary and backup-heater consumption in estimates.
Assess siting and noise before ordering
Specify distances, wall reflections, sensitive areas and vibration. Equipment sound power and received sound level are different quantities. Schallrechner supports assessment; a household-appliance analogy or generic distance does not validate the project.
Plan connections and acceptance
Request hydraulic layout, electrical supply, condensate drainage, appropriate frost protection and service access. Guichet.lu states that the commissioning company must request SCRB acceptance within the following month. Assign responsibility for documents, settings, manuals and reports.
Indicative prices in Luxembourg
On quotation
Compare design, heat pump, connections, controls, adaptations and acceptance together. Rated power or appliance price alone is insufficient. Request cost before grants, consumption assumptions and exclusions without blanket savings promises.
Subsidies and grants
No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
Is underfloor heating necessary?
No. Radiators may suit after checking demand and their output at the intended water temperature.
Is split always more efficient?
No. Compare specific models and operating conditions, not architecture alone.
Does quiet mode solve everything?
No. Check acoustics and available heating power in the mode actually planned.
Is annual servicing automatically mandatory?
Clarify equipment and refrigerant obligations, manufacturer instructions and proposed contract separately.
Does a quote secure Klimabonus?
No. Check technical criteria, dates, documents and applicable procedure; a quote alone establishes no entitlement.
