Cost: air-to-water heat pump
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.
Editorial update on 18 September 2026
Compare equal scope
Itemise design, equipment, base, connections, optional tank, controls, electrical connection, hydraulics, installation and tests. Separate removal, radiator work and reinstatement. Monobloc or split architecture alone determines neither price nor efficiency.
Check site-specific costs
Price necessary noise protection, penetrations, lifting, distribution board and condensate drainage. Check frost protection for the selected architecture. Each adaptation should follow an identified need rather than be automatically added.
Assess operation and support
Compare heating and hot water over the same period and needs. State tariffs, seasonal efficiency, backup heat, service and replacement assumptions. Check grants and tax conditions separately. Supposed income categories or a universal savings percentage are not secured financing.

What makes the price vary
Building
Heat loss before and after renovation.
Emitters
Water temperature and necessary work.
Site
Location, access and neighbours.
Use
Hot water, backup heat and controls.
Indicative scenarios
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.
