Four main reasons people fit a heat pump in the Algarve
🏊
Heat the pool and swim from spring to autumn
A pool in Carvoeiro, Lagos, Vilamoura or Alvor is usually only warm enough from June to September. A pool heat pump with a cover keeps it swimmable from roughly April to November, four to eight extra weeks of use, for a fraction of what direct electric heating would cost. Near the sea we fit units with proper anti-corrosion protection.
In the inland Algarve, Silves, Monchique, São Brás, Alte, there's no mains gas, so hot water often comes from gas bottles or expensive immersion heaters. A hot-water heat pump runs at roughly a quarter of the cost (COP around 4: about 4 kW of heat for every 1 kW of electricity), ends the bottle swaps, and pairs nicely with solar panels you may already have.
If you let your villa, guests constantly ask whether the pool is heated. A heat pump fills the shoulder months (April–June, September–October) and justifies a higher rate, so on a well-marketed property it often pays for itself in 18–30 months. We quote with the payback maths and can handle the whole job while you're abroad.
Whole-home heating and hot water, run off your solar
Many Algarve homes have no real heating beyond the AC, and winters can be cold and damp. An air-to-water heat pump heats the home and the hot water from one unit, works with existing radiators, and runs largely off your own solar panels. We'll explain air-to-water vs air-to-air plainly and size it to your house, not over-sell.
We have a villa in Carvoeiro with an 8×4 pool, and we're here much of the year. The pool is only really swimmable June to September and we'd love to use it for longer. What does a pool heat pump cost to install and to run here, and is it better than solar? And do we really need a cover?
Paul & Linda · 2:22pm
For an 8×4 pool we'd fit an inverter pool heat pump with anti-corrosion protection for the coast, plus a thermal cover. The cover is the key: without one, heat escapes overnight and any system is uneconomical. With it, you'll swim comfortably from about April to November. A heat pump is cheaper to run than solar is to fit for a pool this size, and it works on cloudy days too. Running cost is roughly €120–220/month in the cooler months only.

I live in a farmhouse near Silves. Hot water and heating come from gas bottles and an old gas heater, and last year I paid a lot for gas. I'm tired of swapping bottles. I have old cast-iron radiators and a few solar panels already. Can a heat pump give me hot water and heating more cheaply, does it work with the old radiators, and does it use my solar? Please explain simply.
Andreas · 5:40pm
Good news: cast-iron radiators are ideal for a heat pump, the thermal mass works well. We'd fit a high-temperature air-to-water unit made to retrofit old radiators, with no pipework changes, plus a 300-litre hot-water tank, and a simple thermostat (no app required). It runs largely off your solar in the daytime. A heat pump uses roughly a quarter of the energy of gas for the same heat, so against your current gas bill the saving is large and it typically pays back in about 6 years, then years of clean saving after that.

I let a villa near Lagos and live in Dublin. Bookings drop off outside July–August and guests keep asking if the pool is heated. If I add a heat pump, will the extra shoulder-season bookings pay for it? And can you survey, quote and install while I'm in Ireland, with an invoice for my NIF?
Ronan · 11:08am
Yes to both. We'd fit an inverter pool heat pump with a thermal cover and anti-corrosion protection for the coast. A heated pool typically adds bookable weeks in April–June and September–October and lets you charge a higher rate; on a well-marketed villa the extra revenue is often €4,000–7,500 a year, so it pays back in roughly 18–30 months. We survey by video with your cleaner, email you the quote with the payback maths, install while you're in Dublin, and send photos plus a fatura with your NIF.

I live near Loulé full-time and have solar panels. The house has no real heating beyond the AC and it's cold and damp in winter. I'd like proper heating and hot water for the colder months, run as much as possible off my own panels. What's the difference between air-to-water and air-to-air, and which suits a house like mine? I'd like clear advice, not a hard sell.
Marloes · 11:15am
For your house an air-to-water heat pump is the right choice: it heats the home (through radiators or underfloor) and the hot water from one unit, unlike air-to-air, which only heats the air in a room like an AC unit does. We'd fit an air-to-water unit with a 200–250 L hot-water tank, sized to your house, and set it to run mainly in the daytime so it uses your solar. We'll show you the running cost in writing first, and we won't fit a bigger system than you need.

2026 figures: electricity €0.21/kWh, bottled/bulk gas around €0.175/kWh. A heat pump delivers roughly 4 units of heat per unit of electricity. In a heavy-use case (bulk gas in an inland home) the saving can reach about €1,800/year. We calculate the exact payback for your property on the survey.

Four kinds of project across the Algarve: coastal homes (Burgau, Sagres, Praia da Luz, Alvor, Carvoeiro), where units need proper anti-corrosion protection for the salt air; resort villas and rentals (Vilamoura, Quinta do Lago, Vale do Lobo, Albufeira), pool heating and hot water with seasonal servicing; rental portfolios (Olhão, Tavira), several hot-water heat pumps installed together; and inland homes off the gas grid (Alte, Monchique, Salir), high-temperature air-to-water to retrofit old radiators plus a 300 L hot-water tank.
Heat pumps in the Algarve: common questions
Yes, and the payback is one of the quickest. Heating a 50 m³ pool with a direct electric heater costs around €116/month in season. A pool heat pump (from €2,199 + VAT) does the same for around €23/month, a saving of about €650 a season and payback in 3–4 years. It also stretches the swim season from June–September to roughly April–November, more use of the property, and for rentals, more shoulder-season bookings with a heated pool. A thermal cover is essential to keep it economical.
One of the best cases in the Algarve. Bulk gas is expensive, and a heat pump delivers roughly four units of heat per unit of electricity. For a home spending €2,000–2,500/year on gas (heating + hot water), the saving can reach about €1,800/year. A high-temperature system with a 300 L tank is typically from €10,500 + VAT, paying back in about 6 years, then years of clean saving. Old cast-iron radiators actually suit a heat pump well, with no pipework changes, and we confirm in writing that your power supply is enough (it usually is).
Ideal for a 200 L hot water heat pump. Gas bottles cost roughly €35/month in hot water for two people; a hot water heat pump does it for around €12/month. The system is from €1,899 + VAT, fitted in one day with no gas work, keeping your existing taps. Simple controls on the unit (no app required), 3-year equipment + 1-year labour warranty, and it lasts 15+ years. It also pairs well with solar panels.
It depends on what you're replacing. Bulk gas (inland home spending €2,000+/year): payback 5–7 years, then years of clean saving. An oil boiler with existing radiators (part-year home): around 8 years. A pool heat pump for a rental: roughly 3–4 years on energy, or far quicker counting the extra bookings a heated pool brings. Gas bottles for hot water: about 7 years. In every case we calculate with current tariffs and a correctly sized system, and put the numbers in writing before you commit.
The Algarve is the best climate in Portugal for heat pumps, in both seasons. In summer they run at peak efficiency; in the mild winters (averaging 10–14 °C in Faro) an air-to-water unit still performs very well, better than in Lisbon or the north. It's an ideal climate, and installers here have more experience with pools and holiday villas than elsewhere in the country.
For typical Algarve use, a seasonal pool (April–October) and a house used in winter too, two separate systems are usually cheaper overall and more efficient. The house unit runs low-temperature for radiators, a different job from a pool unit moving large amounts of heat into a body of water. A combined system only makes sense in a year-round home where both run at once. We price each: air-to-water for the house around €7,500–12,000 + a pool heat pump around €2,500–4,500, typically €10,000–16,500 + VAT in total.
Yes, it's real within about 2 km of the coast (Albufeira, Lagos, Praia da Luz, Portimão, Vilamoura, Carvoeiro). For those areas we fit anti-corrosion (marine-grade) units, treated coils and a marine-painted casing. It adds roughly 5–10% to the equipment but can double the life in salt air, from about 8 years to 15+. Inland (Silves, Monchique, São Brás) standard equipment is fine. We advise based on your distance from the sea on the survey.
We work with many overseas owners. A pre-season visit in spring (before you or guests arrive): gas and filter checks, controls, a remote-operation test, with a report emailed to you. Annual servicing is around €120–150/year and keeps the warranty valid. If something fails during your stay, an engineer is there within 24–48h. We arrange access with whoever holds the keys, your cleaner, a neighbour or your manager, so you don't need to be here.
A modern inverter unit is about 45–55 dB at 1 metre, roughly a quiet conversation. Outdoors we keep the legal minimum distance from neighbours' windows; pool units go in the plant area away from seating; a hot-water unit in a garage or outbuilding is inaudible indoors. In tighter historic streets we can use extra-quiet models (under 35 dB) at little extra cost.
It's the ideal pairing, even more so in the Algarve with 2,800+ hours of sun a year. Panels peak at midday, exactly when a hot-water or pool heat pump can run. You can set the heat pump to run mainly during solar production, so in summer the electricity is close to free. If you already have panels, we coordinate the setup and program the controls to prioritise your own solar.
The same: 3 years on the equipment + 1 year on our labour, above the legal minimum, and it holds on the coast with the anti-corrosion units. Annual servicing keeps it valid, and we include a spring pre-season visit on rental contracts. If something fails, an engineer is there within 24–48h. For the remotest spots (Sagres, Aljezur, Alcoutim) a €30–60 call-out may apply, always shown in the quote up front.
