Aerotermia Hot Water
(ACS) in Valencia
The heating season in Valencia is short; the shower season never ends. We put your domestic hot water — the ACS — on aerotermia: a cylinder warmed by heat drawn from the Mediterranean air, sized around how your household actually showers, with the old butano or electric termo gone the same day. Fixed written quote before we start, 2-year workmanship warranty when we finish.
Agua Caliente Sanitaria con Aerotermia
Hot Showers, Powered
by Valencian Air
Every hot water system is really a savings account: you pay energy in, you draw showers out. Aerotermia changes the exchange rate — the cylinder is warmed by a small heat pump harvesting warmth from outside air, so a large share of every shower's heat comes from the sky rather than the meter.
We install the full range: ACS cylinders tied into complete aerotermia systems, standalone termo aerotérmico units for flats, and straight swaps for tired butano calentadores. Whatever the starting point, the finish is the same — steady hot water, a smaller bill, and no more bottles.

Del Butano a la Aerotermia
Who Calls Us About Hot Water
From beach flats still married to butano bottles to villas where the shower goes cold by the third teenager — these are the households we help most weeks.
Busy Family Bathrooms
Cylinders sized so the fourth shower of the morning runs as hot as the first.
Flats Wanting One Simple Upgrade
A termo aerotérmico swap: same cupboard, a fraction of the consumption, done in a day.
Holiday & Rental Homes
Hot water that guests can't break and owners can check from another country.
Coastal Villas Going All-In
Full aerotermia in Puçol or El Puig, with ACS designed in from the start rather than bolted on.
Kitchens Ditching the Gas Heater
That wall-mounted calentador over the sink? We remove it, cap the gas and free the wall.
Get the Litres Right
Aerotermia ACS: The Tank Matters More Than the Pump
We Size Around Showers, Not Square Metres
Ask how big someone's home is and you learn little about their hot water; ask what happens between 7 and 9 in the morning and you learn everything. Teenagers who shower daily, a bathtub that actually gets used, a rain-head shower that pours generously — each changes the cylinder we recommend. Undersize it and the last shower runs cool; oversize it and you pay to keep water hot that nobody uses. The survey exists to land exactly in between.
- ✓ Litres matched to your real routine
- ✓ Reheat windows set around your day
- ✓ Anti-legionella cycles automated
- ✓ Expansion vessel and safety group
- ✓ Cheap-tariff charging where it helps
- ✓ Recirculation for distant bathrooms
- ✓ Well-insulated tanks that hold heat
- ✓ Flow and pressure checked at every tap
The Square Meter Difference
Water Is Our Family
Business — Literally
Square Meter Air shares a workshop and a surname with Square Meter Plumber, so an ACS installation here is done by people who think about pipework, pressure and drains as much as compressors. That combination shows in the finish.
- A survey that maps your actual hot water day
- One fixed written price for the whole job
- Plumbing-grade pipework, valves and lagging
- Coastal placement that respects the salt air
- Old termos and butano gear taken away
- Anti-legionella programming as standard
- Controls explained until they make sense
- Two years of written cover on our workmanship

Just the Hot Water, Please
Termo Aerotérmico: A Heat Pump for Your Cylinder Alone
The Flat-Friendly Upgrade That Skips the Building Work
Plenty of Valencia flats don't need a heating revolution — winter is handled, summer has its splits, but the electric termo is quietly eating the bill. A termo aerotérmico swaps that resistance heater for a compact all-in-one unit that pulls warmth from the air in your galería or trastero. No outdoor unit, no comunidad conversations, usually installed in a morning — and far gentler on the electricity meter than the tank it replaces.
- ✓ All-in-one unit, no outdoor module
- ✓ Fits galerías and utility rooms
- ✓ Runs on a normal household circuit
- ✓ Uses far less power than a termo
- ✓ Duct options for intake and exhaust
- ✓ Same-day swap from an electric tank
- ✓ Butano heater removal included
- ✓ Smart timers for off-peak heating

Aerotermia ACS from the Beach to the Northern Coast
Salt Air Respected, Distances Short
Hot water jobs cluster along the sea: in El Cabanyal and La Malvarrosa we're often swapping butano heaters in reformed fishermen's houses, while Patacona and Port Saplaya bring newer flats where a termo aerotérmico slots neatly into a galería. The salt air is part of every survey here — outdoor units get sheltered positions and a sensible maintenance habit. Up the coast road, family homes in Puçol, El Puig and La Pobla de Farnals usually pair a full aerotermia system with a generously sized ACS cylinder.

Local Insight
Here, Hot Water Is the Marathon — Heating Is Just a Sprint
Valencia flips the usual heat-pump logic on its head: heating might run a couple of months a year, but the shower runs every single day, so ACS quietly becomes the biggest energy line in many households. The same mild air that makes winters easy also keeps a hot water heat pump in its comfortable working range all twelve months — a January morning here is warmer than an October one in much of northern Europe. Size the tank around the family's real rhythm and the cost of hot water stops being something you ever think about.

Aerotermia Hot Water
Valencia FAQ
How many litres of hot water cylinder do we need?
We size it from your routine, not a table. Two showers back-to-back at 7:30, a bath for the kids at night, a dishwasher on a hot feed — those details decide the litres. The cylinder should cover your busiest stretch of the day comfortably, because the heat pump quietly refills it afterwards.
+
What is a termo aerotérmico?
It is a hot water cylinder with its own small heat pump built into the top. Instead of resistance coils it extracts warmth from the surrounding air, using far less electricity than a classic termo eléctrico. For flats that only want to fix their hot water bill — no heating changes — it is often the smartest single upgrade.
+
Can you replace my butano water heater?
Gladly — it is one of our most requested jobs near the beach. We remove the gas calentador and the bottle setup, fit an aerotermia cylinder or termo aerotérmico in its place, and you stop hauling orange bottles up the stairs for good. Most swaps are finished within a day or two.
+
What about legionella in a hot water tank?
Every system we install runs an automatic anti-legionella cycle: at programmed intervals the tank is raised to a high disinfection temperature, then returns to its efficient everyday setting. It happens on schedule, typically overnight, without you touching anything.
+
Will the shower go lukewarm when the whole family piles in?
Not if the cylinder is sized honestly — which is exactly why our survey asks so many questions about mornings in your house. We also set sensible reheat windows so the tank recovers between the morning rush and the evening one, and cheaper tariff hours can do much of that work.
+
Does salt air near the beach affect the outdoor unit?
It can if you ignore it. In Cabanyal, Malvarrosa and Patacona we position outdoor units away from direct sea spray where possible, favour sheltered mounting spots, and recommend a rinse and inspection as part of annual maintenance. Handled that way, coastal units live long, useful lives.
+
How long does an aerotermia hot water installation take?
A standalone termo aerotérmico is usually fitted and heating water the same day. A full ACS cylinder connected to a new aerotermia system typically needs a day or two more, depending on where the old equipment was and where the new tank is going. The written quote states the schedule.
+
Which coastal areas and towns do you cover?
The beach districts of Valencia — El Cabanyal, La Malvarrosa and Patacona — plus Alboraya, Port Saplaya and the coast road north through Puçol, El Puig, La Pobla de Farnals, Massamagrell and Rafelbunyol. Inland Valencia is covered too, of course.
