Heat Pumps: Efficient Comfort All Year Round
A heat pump is now the most efficient way to heat and cool a home and to produce domestic hot water. Rather than generating heat by burning something, it moves heat that already exists in the outside air — which is why it delivers several times more energy than it consumes. In the mild Algarve climate, where winters are gentle, aerothermal systems perform particularly well, and that translates into a very significant saving compared with gas water heaters, immersion cylinders or boilers. Visky installs heat pumps for homes, holiday lets and commercial premises across the region.
Replacing an old system with a heat pump is often the single efficiency upgrade with the biggest impact on your bill. We assess your case — your need for heating, cooling and hot water — and propose the right equipment, sized to your property, with nothing wasted.
What a Heat Pump Does for You
- Domestic hot water — a heat pump water cylinder typically uses around a third of the electricity of a conventional immersion heater.
- Heating in winter — gentle, even warmth, ideal for the damp evenings that catch newcomers to the Algarve by surprise.
- Cooling in summer — reversible units cool as well as heat, so one machine covers the whole year.
- Pool heating — a dedicated pool heat pump extends your swimming season by months. See pool heating and spas.
Why Aerothermal Works So Well Here
Heat pump efficiency drops as the outside air gets colder. That is the limitation that makes them a compromise in northern Europe — and it is precisely the limitation the Algarve does not have. With mild winter temperatures, a well-specified unit runs near its best efficiency for most of the year. For a household coming from the UK, where a heat pump is often a difficult retrofit, the equation here is far more favourable.
Damp is the other factor worth naming. Many Algarve properties, especially older village houses and villas that stand empty part of the year, suffer from humidity in winter. Steady background heat from a heat pump does more for that problem than an occasional blast from a portable heater.
Solar and Heat Pump Together
A heat pump typically delivers three to four times more heat energy than the electricity it consumes. Powered by solar panels, its daytime running cost approaches zero. This is why we almost always recommend the combination: it is the basis of a genuinely efficient and comfortable Algarve home, and both systems come from the same team.

- 3 shops in Lagos, Almancil and Aljezur, with our own technical team.
- Aftercare and servicing from the people who did the installation.
Frequently Asked Questions
A heat pump water cylinder typically consumes around a third of the electricity of a conventional immersion heater, because it moves heat rather than generating it. For a family household that is usually the fastest-paying efficiency upgrade available.
Very well. Heat pumps lose efficiency in hard frost, which is why they are a compromise in northern Europe — but Algarve winters are mild, so a properly specified unit runs near its best efficiency almost all year.
Yes. Reversible heat pumps provide heating in winter and cooling in summer from one machine, which keeps both the installation cost and the maintenance simpler.
Yes, and it is the combination we recommend most often. The heat pump consumes most during daylight hours, which is exactly when the panels produce, so a large part of its running cost disappears.
