Aerothermal heat pumps in Catalonia: efficient heating, cooling and hot water
Catalunya Servei designs and installs air-to-water aerothermal systems for heating, cooling and domestic hot water across Catalonia, with a prior consumption study and registration included.
From €6,500 installed
Is an aerothermal heat pump worth it in Catalonia?
Yes for homes in daily use: with a COP above 4, it cuts heating and hot water consumption by 50-60% versus gas and pays for itself in 6-9 years.
Since 2019 we've completed over 200 aerothermal installations in Catalonia, and the pattern repeats: it performs best in homes with underfloor heating or low-temperature radiators and continuous use. In small flats with little heating use, payback takes longer — and we'll tell you so honestly in the free preliminary study. If you have roof space, pairing it with solar panels is unbeatable: the solar surplus powers the heat pump.
Air-to-water vs. air-to-air: which do you need?
Quick answer: Air-to-water feeds radiators or underfloor heating and produces hot water; air-to-air only conditions room air. To replace a boiler, you need air-to-water.
| Criterion | Air-to-water | Air-to-air (splits) |
|---|---|---|
| Indicative price | €6,500 – 12,000 | €750 – 2,400 |
| Domestic hot water | Yes, with integrated tank | No |
| When to choose it | Boiler replacement, new build | Room climate control only |
Many clients combine both: air-to-water for heating and hot water, plus a split in the living room for occasional summer cooling.
Frequently asked questions
How much does an aerothermal installation cost?
Between €6,500 and €12,000 depending on power, hot water tank and existing emitters. The preliminary study with savings simulation is free.
Are there grants for aerothermal systems?
Depending on the current schemes there are energy renovation grants and municipal rebates. The study tells you what you can apply for, and we help with the paperwork.
Does aerothermal work with old radiators?
It works, but performs worse with high-temperature radiators. During the visit we calculate whether replacing some emitters keeps the COP high.
