Hot water for about a quarter of the cost of gas
In a city apartment the biggest win is hot water. A hot water heat pump replaces a gas water heater (esquentador), an old electric cylinder or bottled gas, keeping your existing taps, and runs for around €24/month instead of ~€92 — roughly 60% less. From €1,899 + VAT, fitted in a day, no gas work, and it pairs neatly with solar.
On the Cascais–Estoril line we plan one integrated system for a villa: an air-to-water heat pump for heating and hot water, plus a pool heat pump to extend the swim season. It replaces an old oil or gas system in one go. We size each part honestly, price them separately so you can see the numbers, and never over-sell.
Lisbon winters are mild but damp, and an air-to-water heat pump takes the chill off the whole house far more cheaply than a gas boiler or electric heaters. Modern units work well with your existing radiators (a couple may be swapped for low-temperature emitters). Replacing a gas boiler with air-to-water is from €6,299 + VAT — ideal on a renovation, especially paired with solar.
Honest sizing and payback — in writing, in English
We survey the property, size it for real and put the running cost and payback in writing before you commit — no over-selling, no brochure figures. Everything is handled in English, you get an official fatura with your NIF for NHR or IRS, and our technicians are F-Gas Cat. I certified. We also help with condominium permission for an outdoor unit.

Cascais villa — one system for everything
website formCascais
Good morning. We have a villa in Cascais, about 180 m², with a pool and an old oil/gas system feeding the radiators and the hot water. Last winter the fuel bills were painful — close to €3,200 on the year. We'd like one heat pump for hot water, heating and the pool, and we'd want the running costs and payback in writing before we commit. English-speaking, please, and not over-sold. Will it work with our existing radiators?
Geoffrey & Susan · 10:45
Hello Geoffrey and Susan. This is exactly the Cascais villa case we plan most. We'd put in one integrated system: a premium air-to-water monobloc 12 kW unit + a 200 L hot water tank for the house and hot water, plus a separate pool heat pump so each does its job efficiently. Being honest about the physics — your existing radiators run at 50–55 °C, so expect a real efficiency around 3.0–3.2 (not the 4.0 you'll see in brochures, which assumes underfloor heating). On your fuel use that's roughly €1,020/year of electricity for heating and hot water, against about €3,200 today — a saving near €2,180/year. We size each part, price them separately and give you the payback in writing before you decide.

Survey on the Saturday confirmed every radiator had headroom; the pool heat pump was specified separately. Installed before Christmas. The first full January bill came in around €178 for the whole house — heating, hot water and all.
Hi. I have a one-bedroom apartment in Príncipe Real with a gas water heater (the esquentador) and the gas bills are high. I read that a hot water heat pump runs at about a quarter of the cost — can I fit one instead in an apartment? Will I need condominium permission for the outdoor unit, and can you do it in English with an invoice for my NIF?
Megan · 19:32
Hello Megan. Yes — this is the most popular job we do in the city, and it's straightforward in an apartment. We'd fit a 200 L hot water heat pump on your balcony, keeping your existing taps; no gas work. The outdoor part is small, and on a private balcony you generally don't need a building (condominium) vote — we give you a short technical note for the building just in case. It runs for around €24/month against roughly €92 at the winter peak today — about €430+/year saved. Everything in English, and you get an official fatura with your NIF for IRS/NHR.

Survey on the Thursday evening, fitted the following Saturday in a single day. Megan kept her taps, the old gas water heater was removed, and she had the invoice with her NIF the same week.
Good afternoon. I am retired in Estoril and I heat my water with gas bottles, which I am tired of changing. I would like a hot water heat pump — something simple and good value, nothing complicated. Could you explain it to me in English, and tell me what it costs and how much I would save?
Brigitte · 18:42
Hello Brigitte. A hot water heat pump is exactly right for you — simple, reliable kit, no gadgets and no more bottles to change. We'd fit a 200 L unit on the balcony, keeping your existing taps; it's a one-day job with no gas work. Bottled gas costs roughly €35/month for hot water; the heat pump does the same for around €12/month — about €430/year saved, paying back in 3–4 years, and it lasts 15+ years. The controls are on the unit itself, no app needed. Fair price, explained in plain English.
A quick survey confirmed the balcony spot and the connection. Fitted in one day, the gas bottles gone for good. Brigitte got a single clear price and a simple unit she can run herself.
Hello. I'm renovating an older house near Sintra and I want to replace the gas boiler with an air-to-water heat pump for heating and hot water, working with my solar panels. Can you size it properly for the house, confirm my radiators and electrical supply are OK, coordinate with my builder, and explain it all in English with proper documentation?
Lars · 9:47
Hello Lars. A renovation is the best time to do this. We'd specify an air-to-water heat pump for heating and hot water — for example an air-to-water monobloc 7 kW — sized to your house's heat load, from €6,299 + VAT. We confirm in writing that your electrical supply suits a heat pump and check each radiator; most work fine as they are, and we'd only suggest swapping a couple for low-temperature emitters if the figures call for it. It's the ideal pairing with solar: we program the controls to use your own production first, so much of your hot water is close to free. We coordinate timing with your builder and give you full English documentation.

We confirmed the supply and radiators in writing, coordinated the install with Lars's builder mid-renovation, and tied the controls into his new solar. All-electric house, gas boiler gone, documentation in English.

2026 tariffs: electricity €0.1885/kWh · mains gas €0.11/kWh · bottled/bulk gas (LPG) €0.15–0.18/kWh. Real efficiency depends on your emitters: existing radiators = 2.8–3.4 · low-temperature fan-coils = 3.4–3.8 · underfloor heating = 3.8–4.2. For hot water, the certified COP (EN 16147) is 3.0–3.5. Actual figures depend on exposure, insulation and habits — we cross-check against your own bill at the survey and give the payback in writing.

Four kinds of home across Greater Lisbon, each with a different answer: central Lisbon apartments (Príncipe Real, Estrela, Avenidas Novas) — a hot water heat pump replaces a gas water heater or an electric cylinder, with help on condominium permission; the Cascais–Estoril villa belt — one integrated system for hot water, heating and the pool, replacing an old oil or gas setup; villas off the mains-gas network (Cascais, Sintra, Mafra and the hills) — air-to-water with an integrated hot-water tank to replace bottled or bulk gas; the coast (Cascais, Carcavelos, Oeiras) — pool heat pumps with an anti-corrosion casing. We also cover the Silver Coast and the Algarve from sibling pages.
Heat pumps in Lisbon — common questions
Yes — English from the first call to the written report. We survey the property, explain the options in plain English, and put the sizing and payback in writing before you commit. You get an official fatura (invoice) with your NIF for NHR or IRS. Our technicians are F-Gas Cat. I certified, and we work across Greater Lisbon — central Lisbon (Príncipe Real, Estrela), the Cascais–Estoril line, Sintra and Oeiras.
Yes — this is the most popular job in the city. A hot water heat pump replaces a gas water heater (esquentador, very common here), an electric cylinder or bottled gas, keeping your existing taps and showers. A 200 L unit is from €1,899 + VAT, fitted in one day with no gas work, and a city apartment usually doesn't need a vote of the building (condominium) because it sits on a private balcony. It runs at about a quarter of the electricity of an old electric cylinder and far less than bottled gas.
A 200 L hot water heat pump is from €1,899 + VAT (300 L from €2,399 + VAT for a larger household). On a typical Lisbon apartment heating water with an electric cylinder, the bill runs about €92/month at the January peak; a hot water heat pump does the same job for around €24/month — roughly €430–€816 a year saved. That pays back the €1,899 in about 3–4 years, then it's years of clean saving. Against bottled gas the saving is even clearer. It pairs well with solar panels.
For a Cascais or Estoril villa we plan it as an integrated system: an air-to-water heat pump for the heating and hot water, plus a dedicated pool heat pump (from €2,199 + VAT). A full air-to-water bundle with a 200 L hot water tank — for example an air-to-water monobloc 12 kW + 200 L DHW tank — is from about €9,098 + VAT and replaces an old oil or gas system in one go. We size each part honestly, price them separately so you can see the numbers, and put the running cost and payback in writing — no over-selling.
Yes — coastal Lisbon is one of the easiest climates in Europe for a heat pump. Lows are mild (roughly 2–6 °C on the coast, a little colder up in the Sintra hills), and modern R290/R32 air-to-water units hold their efficiency well. Real efficiency depends on your emitters: underfloor heating gives the best figures, low-temperature fan-coils are next, and existing cast-iron radiators still work at a slightly higher water temperature. In every case it's 3–4× more efficient than electric heaters or an electric cylinder, and it takes the damp chill off the house through the winter.
It depends where the unit goes. On a private balcony or enclosed terrace — which is how most hot water heat pumps are fitted in apartments — you generally don't need a building vote, as it's within your own apartment. On a shared wall, façade or roof — typical for a larger air-to-water unit — you do need the condominium's agreement. The outdoor unit is no bigger than a normal air-conditioning condenser. We give you a technical dossier (photo, install plan, a short note) to take to the building; handling the actual permission is the building manager's job, but we make it easy.
Very well — it's the ideal pairing for a renovation or an all-electric home. Solar output peaks in the middle of the day, which is exactly when a hot water or pool heat pump can run, so you heat your water and pool largely on your own free electricity. If you already have, or are planning, solar PV, we coordinate the setup and program the controls to use your own production first. For a renovating owner near Sintra dropping a gas boiler, air-to-water + solar is the obvious all-electric route.
It depends on what you're replacing, and we calculate it on your own bill before you commit. Replacing an electric cylinder or gas water heater with a hot water heat pump (from €1,899 + VAT): about 3–4 years. Replacing a gas or oil boiler with an air-to-water system: roughly 7 years, then 15+ years of clean saving. Replacing bottled or bulk gas at a rural villa (the most expensive fuel) with an integrated bundle from €9,098 + VAT: around 4 years. A pool heat pump for the season: about 4 years. We size correctly and put the figures in writing.
Yes. On a renovation we coordinate with your builder and confirm the practical points up front: that the electrical supply suits a heat pump (it usually does), and whether your existing radiators are fine as they are or whether a couple should be swapped for low-temperature emitters. Modern air-to-water units run existing radiators well, and most homes need little or no pipework change. An air-to-water system replacing a gas boiler is from €6,299 + VAT, and we'll tell you honestly which option gives the best efficiency for your house.
Always. Every job comes with an official fatura (invoice) showing your NIF, which you need for NHR or IRS. Prices on this page are shown + VAT. You also get the written sizing and payback estimate, a 3-year equipment warranty plus 1 year on our labour, and the option of a simple annual service to keep everything running and the warranty valid — €99/year for one visit, or €199/year for two visits including F-Gas registration where it applies.
