Heat pumps on the Silver Coast — air-to-water heating for the cooler, damper winter.
English-speaking heat-pump installation across the Silver Coast. If you're renovating an older house near Caldas or Óbidos, mid-works is the cheapest moment to fit an air-to-water heat pump for heating and hot water. It heats the whole house through the cooler, damper winter far more cheaply than a gas boiler or electric heaters, and a hot water heat pump replaces gas bottles or a gas boiler for about a quarter of the cost. We put the sizing, running cost and payback in writing — in English, with a fatura and your NIF.

Why expats on the Silver Coast are fitting heat pumps
🔧
Fit it during the renovation — while the walls are open
Mid-renovation is the cheapest moment to put in an air-to-water heat pump for heating and hot water, with the pipework accessible and the builder already on site. We size it for the older house, coordinate the timing, and replace the gas boiler in the same works. An air-to-water system is from €6,999 + VAT — and far easier to fit now than after the plastering's done.
Real heating for the cooler, damper Silver Coast winter
The Silver Coast is cooler and damper than the Algarve, so air-to-water heating is a genuine lever here, not just summer comfort. A heat pump takes the chill and the damp off the whole house far more cheaply than electric heaters or a gas boiler — typically 3–4× more efficient. A full air-to-water + hot water system is from €7,499 + VAT, and it works with your existing radiators.
If you're tired of swapping gas bottles, or paying a gas boiler just for hot water, a hot water heat pump does the same job for roughly a quarter of the cost, keeping your existing taps. From €2,099 + VAT, fitted in a day with no gas work — a simple swap for an electric cylinder, a gas water heater (esquentador) or bottled gas, and it pairs neatly with solar.
Honest sizing and payback — in writing, in English
We survey the house, 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 work happily with part-year owners abroad, through a key-holder.

Renovating near Caldas — air-to-water + hot water
website formCaldas da Rainha
Good morning. We've relocated and we're renovating an older house near Caldas, walls still open. We want to skip the gas boiler and put in an air-to-water heat pump for the heating and hot water — maybe adding solar later. Can you size it for the house, work with our builder on timing, and confirm our radiators and the power supply are suitable? We'd want the running costs in writing, in English, before we commit.
Mark & Jo · 10:20
Hello Mark and Jo. Mid-renovation is the ideal time — the pipework's accessible and we can plan it around your builder. We'd specify a full air-to-water + hot water system, for example a premium air-to-water monobloc 12 kW + a combined 200 L tank, from €7,499 + VAT, replacing the gas boiler in one go. Being honest about the physics: your existing radiators run at 50–55 °C, so expect a real SCOP around 3.0–3.2 in the cooler, damper Silver Coast climate (not the 4.0 in brochures, which assumes underfloor heating). We confirm in writing that the supply suits a heat pump and check each radiator — most are fine, and we'd only swap one or two for low-temperature ones if the figures call for it. It's the perfect base for solar later: we wire the controls to use your own production first.
€7,499 + VAT (air-to-water + hot water, fitted in the renovation) · payback ~6–7 years · warranty 3+1

Survey confirmed every radiator had headroom; we coordinated the install with their builder mid-works, before the plastering went back. Gas boiler gone, controls left solar-ready for the panels they're adding next year — full documentation in English.
Foz do Arelho holiday home — pool + hot water, from abroad
WhatsAppFoz do Arelho
Hello. We have a holiday house near Foz do Arelho with a small pool, and we live in the Netherlands most of the year. We heat the water with gas and the pool is only really usable in high summer. We'd like a pool heat pump and cheaper hot water, all sorted before our next stay. We are away now — could you quote, work with our key-holder and fit it while we're abroad, and email us the invoice? Simple clear English, please, and payment by transfer.
Hans & Greet · 11:28
Hello Hans and Greet. We do this regularly for part-year owners — we work through your key-holder, send photos at each stage and email the fatura; you pay by bank transfer. We'd fit a pool heat pump with a marine-grade casing for the salt air (from €2,999 + VAT), which with a thermal cover extends the season from about May to October — a real difference here, as the coast is cooler than the Algarve. Alongside it, a hot water heat pump to replace the gas (from €2,099 + VAT) cuts the hot-water bill to roughly a quarter. Together that's about €5,098 + VAT, both fitted while you're away so the house is ready the day you arrive.
€5,098 + VAT (pool heat pump + hot water) · fitted before arrival, fatura by email
VentoFix · 14:36
Surveyed with the key-holder, quote and photos sent to the Netherlands, approved by email. Pool heat pump and hot water fitted while they were away; the fatura went out by email and they paid by transfer. House warm and the pool ready the week they flew in.
Good afternoon. I am retired in São Martinho do Porto and I heat my water with gas bottles, which I am tired of carrying and changing. I would like a hot-water heat pump — something simple and good value, nothing complicated, made to last many years. Could you explain it to me in English, and tell me what it costs and how much I would save? Nothing I don't need.
Ingrid · 16:54
Hello Ingrid. A hot-water heat pump is exactly right for you — simple, reliable kit, no gadgets and no more bottles to carry. We'd fit a 200 L unit (from €2,099 + VAT) in the place of your cylinder, keeping your existing taps; it's a one-day job with no gas work. The controls are physical buttons on the unit itself — on, off, temperature — no app, no internet. On the figures: gas bottles cost roughly €50/month for hot water, the heat pump does the same for about €17/month — around €395 a year saved, paying back in about 5 years, and it lasts 15+ years. Near the coast we add a marine-grade casing so the salt air doesn't shorten its life. A fair single price, explained in plain English.
€2,099 + VAT (200 L hot water heat pump, installation included) · payback ~5 years
VentoFix · 18:22
A quick survey confirmed the spot and the connection. Fitted in one day, the gas bottles gone for good. Ingrid got a single clear price and a simple unit she can run herself, with the fatura and her NIF the same week.
Caldas family — cold, damp winter on electric heaters
WhatsAppCaldas da Rainha
Good afternoon. We moved to Caldas with the family and the house is cold and damp this first winter — we're heating with electric heaters and it's costing a fortune. I want an air-to-water heat pump for the whole house and the hot water, to replace the electric heaters for good. Can you size it properly, tell me honestly if my existing radiators are fine or need changing, and give me one fixed price in English? People said the Silver Coast was mild — it's cooler and damper than we expected.
Conor · 14:05
Hello Conor. You're right — the Silver Coast is cooler and damper than people expect, which is exactly why air-to-water heating makes sense here. We'd specify a full air-to-water + hot water system, for example a premium air-to-water monobloc 12 kW + a 200 L tank, from €7,499 + VAT, to heat the whole house and the water and replace the electric heaters. On the physics: existing radiators run at 50–55 °C, so expect a real SCOP of about 3.0–3.2 — still 3–4× cheaper than electric heaters. On your bills, electric heating runs near €1,990/year against about €1,000/year on the heat pump — roughly €1,000+ a year saved. We measure each radiator at the survey; most are fine, and we swap only the odd tight one (about €250 each). You get one fixed price in writing, in English.
€7,499 + VAT (whole-home air-to-water + hot water) · payback ~6–7 years

2026 tariffs: electricity €0.1885/kWh · off-peak €0.1085/kWh · mains gas ~€0.089/kWh · bottled/bulk gas (LPG) €0.15–0.18/kWh · heating oil ~€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 the Silver Coast, each with a different answer: older houses being renovated (Caldas da Rainha, Óbidos, Bombarral) — fit an air-to-water heat pump while the walls are open, replacing the gas boiler on the existing radiators; homes that are cool and damp in winter — a full air-to-water + hot water system to heat the whole house far more cheaply than electric heaters; part-year holiday homes on the coast (Foz do Arelho, São Martinho do Porto, Nazaré, Peniche) — pool heat pump and hot water with a marine-grade casing, fitted before you arrive; retirees and simple-value buyers — a hot water heat pump to replace gas bottles, with plain physical controls. Always the Silver Coast — towns include Caldas da Rainha, Óbidos, Foz do Arelho, São Martinho do Porto, Nazaré, Peniche, Bombarral, Lourinhã and Alcobaça.
Heat pumps on the Silver Coast — 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 right across the Silver Coast — Caldas da Rainha, Óbidos, Foz do Arelho, São Martinho do Porto, Nazaré and Peniche.
Yes — mid-renovation is the cheapest moment to fit an air-to-water heat pump, while the walls are open and the pipework is accessible. We coordinate with your builder, confirm the electrical supply suits a heat pump (it usually does) and check your emitters. An air-to-water system that replaces a gas boiler is from €6,999 + VAT, or a full air-to-water + hot water bundle from €7,499 + VAT. We size it for the house, plan the install around your works and give you the running cost and payback in writing, in English.
Yes — both are common here. To replace a gas boiler, an air-to-water heat pump connects to your existing radiators (from €6,999 + VAT, or €7,499 + VAT with a combined 200 L hot water tank). To replace gas bottles or a gas water heater (esquentador) just for hot water, a hot water heat pump is from €2,099 + VAT, fitted in a day with no gas work and keeping your existing taps. Both run for roughly a quarter of the cost of bottled gas.
Yes — and this is a stronger reason here than on the Algarve, because the Silver Coast is cooler and damper. An air-to-water heat pump takes the chill and the damp off the whole house far more cheaply than electric heaters or a gas boiler. Real efficiency depends on your emitters: existing radiators run at 50–55 °C and give a real SCOP of 2.8–3.4, low-temperature fan-coils a little more, underfloor heating the most. In every case it's 3–4× more efficient than electric heaters.
It depends on what you're replacing, and we calculate it on your own bill before you commit. A hot water heat pump (from €2,099 + VAT) replacing an electric cylinder or gas bottles pays back in about 5 years. A full air-to-water + hot water system (from €7,499 + VAT) replacing a gas boiler or an electric-heater/wood mix pays back in roughly 6–8 years, then it's 15+ years of clean saving. We size correctly and put the figures in writing — no brochure numbers.
Yes. A pool heat pump is from €2,999 + VAT and, with a thermal cover, comfortably extends the usable season from about May to October — useful here, where the coast is cooler than the Algarve. It's far cheaper to run than an electric heater (around €530 a season saved). For a coastal holiday home near Foz do Arelho or São Martinho do Porto we fit a marine-grade unit so the salt air doesn't shorten its life. We can sort the pool and your hot water at the same time.
Yes — we do this regularly for part-year owners. We can survey, quote and fit while you're away, working with a key-holder, send photos at each stage and email you the fatura. You can pay by bank transfer. It's the easy way to have the pool heat pump and hot water sorted before you next arrive at the holiday home, so the house is ready the day you land.
Very well — it's the ideal pairing, especially on a renovation. 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 dropping a gas boiler, air-to-water + solar is the obvious all-electric route.
Usually they're fine. Older Silver Coast houses tend to have cast-iron radiators that are generously sized, which gives a modern air-to-water heat pump enough margin to run at 50–55 °C (a real SCOP of 2.8–3.4). We measure the heat load against your installed radiators at the survey; in most houses it's a straight changeover. If one or two rooms are tight, we swap just those radiators for low-temperature ones (about €250 each) — rarely more than a couple.
Certified brands we can stand behind and service locally, for air-to-water and hot water; for hot water alone, a simple unit with physical buttons (no app needed) is a good-value choice. We recommend the unit that suits your house and budget, not the most expensive — and you get a 3-year equipment warranty plus 1 year on our labour.
Quieter than people expect — a modern heat pump runs at about the level of a normal air-conditioning condenser, a low hum you barely notice a few metres away, and quietest at night when it works hardest on hot water. We position it sensibly (garden, side wall or rear terrace), keep it clear of bedroom windows and away from a neighbour's boundary, and fix it on anti-vibration mounts. On the coast it gets the same marine-grade casing so the salt air doesn't shorten its life.
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.
Paying high gas or oil bills is no longer the only option. A written payback on your own bill, in 48h.
Bring us your electricity or gas bill, we size it for the cooler, damper Silver Coast climate, and we give you the payback in writing — in English — before you commit.
