What is aerothermal heating and why does it work in Andorra?
An aerothermal heat pump extracts energy from outdoor air to provide heating, cooling and hot water with a single unit — and current models perform down to -20 °C outside.
It is the question we hear most: “what about when it freezes?”. The units we install — Daikin Altherma, Vaillant aroTHERM, Mitsubishi Ecodan — are designed for Nordic climates and keep performing at the typical lows of Canillo or Pas de la Casa. The key is sizing the power and the hot-water tank correctly, which is exactly what our free preliminary study calculates.
How much does a heat pump installation cost in Andorra?
A complete aerothermal installation in Andorra costs between €9,000 and €15,000 depending on power and whether existing radiators are reused, before grants.
The Andorran Government maintains grant schemes for replacing fossil-fuel systems with renewables as part of its energy transition strategy; the amount depends on the current call, and we prepare and submit the full application at no extra cost. In homes with oil-fired radiators, the work usually takes 3 to 5 days and the payback period is 6-8 years at current fuel prices. Combined with solar panels, your heating bill can shrink to a minimum.
Will my existing radiators work with a heat pump?
In most cases yes: existing water radiators work with aerothermal systems when sized for a lower flow temperature, and underfloor heating is the ideal match.
In the preliminary study we measure each room and calculate whether the current radiators are sufficient at a 45-50 °C flow temperature or whether some should be enlarged. It is the detail that separates an installation that truly saves from one that disappoints — which is why we never quote without a visit.
Heat pump vs. condensing boiler: which to choose?
Quick answer: with existing radiators and a tight budget, a condensing boiler is a fair choice; but if you want the lowest running cost and a grant is available, the heat pump wins over the medium term.
| Criteria | Aerothermal heat pump | Condensing boiler (gas/oil) |
|---|---|---|
| Installed cost | €9,000-15,000 | €3,500-7,000 |
| Annual cost (100 m²) | €900-1,300 | €1,600-2,400 |
| Summer cooling | Yes, included | No |
| Grants | Yes | No |
| Service life | 15-20 years | 12-15 years |
| When to choose it | Planned replacement, new build or renovation | Urgent breakdown on a limited budget |
As we tell our clients: if the boiler has already died in mid-January, we fit a condensing boiler within 48 hours and you are warm again; if you can plan the change calmly, a heat pump with a grant is the best energy investment available in Andorra today.
Frequently asked questions about heat pumps in Andorra
What grants exist for heat pumps in Andorra?
The Andorran Government runs energy-improvement schemes that include replacing fossil-fuel boilers with heat pumps. Amounts and conditions depend on each call; Andorra Servei prepares and submits the complete application for you at no extra cost.
Does aerothermal heating work at -15 °C?
Yes. The units we install are rated to operate down to -20 °C or even -25 °C depending on the model, still outperforming electric resistance heating. At high altitude we size the power with a margin for cold spells.
How long does the installation take?
In a home with existing radiators, 3 to 5 working days: boiler removal, mounting of the outdoor and indoor units, hydraulic and electrical connection, and commissioning. In new builds or renovations it fits into the overall schedule.
What maintenance does a heat pump need?
Very little: a check-up every one to two years with evaporator cleaning, pressure checks and regulation verification. Our maintenance contracts can cover it together with the rest of the home’s installations.
