Air-to-Water Heat Pump
Installation in Valencia
"Air-to-water" means the heat pump doesn't blow air around your rooms — it heats and chills water, and the water does the work: warm floors, gentle radiators, cool fan coils and a full tank of hot water. We install monobloc and split hydronic systems across Valencia and the towns to the north, with a fixed written quote up front and a 2-year workmanship warranty behind every job.
Bomba de Calor Aire-Agua Valencia
Water Carries the Heat.
That Changes Everything.
An air-to-air split can only condition the room it hangs in. Pipe the energy through water instead, and suddenly the whole house is connected: every floor loop, every radiator, every tap. That's what an air-to-water heat pump does — and why one machine can retire your boiler, your electric water heater and most of your splits in a single move. Our job is matching that machine to your building: we survey, calculate, recommend monobloc or split hydronic with honest reasoning, and install the lot ourselves.

Homes That Suit Air-to-Water
Where Air-to-Water Heat Pumps Earn Their Keep
The technology adapts to the building: a compact monobloc on a Meliana rooftop is a different animal from a split hydronic system tucked into a Rocafort garage. Six situations we meet every week.
Houses with a Plant Room
Split hydronic setups shine when a garage or utility room can host the module and cylinder.
Huerta Village Houses
Low-rise homes in Meliana, Foios and Museros with easy roof or patio access for the unit.
Chalets on the Northern Line
Detached homes in Godella and Rocafort combining heating, cooling and ACS in one system.
Homes Ditching Electric Heaters
Swap plug-in radiators for water-borne warmth at a fraction of the running cost.
Larger Homes with Fan Coils
Warm and chilled water feeding discreet fan coils, zoned room by room from one unit.
Air-to-Air vs Air-to-Water
What "Air-to-Water" Actually Means
The Difference Is in What Leaves the Machine
Every heat pump harvests energy from the outdoor air. The question is what it does with it next. An air conditioner hands that energy to refrigerant and blows it into one room; an air-to-water unit transfers it into a water circuit that can reach every corner of the house — floor loops, radiators, fan coils and the hot water cylinder. Water holds heat superbly and moves it in silence, which is why an aerotermia home feels evenly warm rather than gusty, and why the same machine can also fill your morning shower.
- ✓ Whole-house heating from one unit
- ✓ Cooling via fan coils or floor loops
- ✓ Domestic hot water (ACS) included
- ✓ Even temperatures, no air blast
- ✓ Silent distribution through pipes
- ✓ Works with existing wet radiators
- ✓ R32 units — the current standard
- ✓ One electricity meter, no gas contract
Why Choose Square Meter Air?

Monobloc vs Split
Monobloc or Split Hydronic — An Honest Comparison
Two Ways to Build the Same Result
A monobloc packs the entire refrigerant circuit into the outdoor unit and sends ready-heated water indoors: fewer boxes, a faster install, no refrigerant work on site. A split hydronic system runs refrigerant lines to an indoor module instead — useful when the outdoor unit must sit a long way from your plant room, and it keeps the water circuit entirely inside the warm envelope. In Valencia's frost-free winters both perform beautifully, so the choice comes down to your building's layout — and we'll tell you plainly which one we'd fit in our own house.
- ✓ Monobloc: one outdoor box, simple install
- ✓ Monobloc: no on-site refrigerant handling
- ✓ Split: indoor module in garage or utility room
- ✓ Split: longer runs without water heat loss
- ✓ Both: heating, cooling and ACS covered
- ✓ Both: quiet, inverter-driven operation
- ✓ Frost risk minimal in our climate
- ✓ Recommended per building, never per stock

Where We Work
Air-to-Water Installations Along the Northern Corridor
From the City Line to the Huerta Villages
This page's territory runs up the northern side of the metro area: the leafy residential streets of Godella and Rocafort, Moncada with its mix of townhouses and newer blocks, and on through Alfara del Patriarca and Vinalesa. Along the huerta, the low-rise village houses of Meliana, Foios and Museros suit monobloc installs particularly well — short pipe runs, easy roof access, patios with room for the outdoor unit. Massamagrell, Almàssera and Tavernes Blanques round out a patch we can reach quickly for surveys, installs and any warranty visit afterwards.

Local Insight
Valencia Is One of the Few Places Where the Monobloc Question Is Easy
In Germany or Britain, choosing a monobloc means worrying about the outdoor water circuit freezing during a winter power cut — installers add glycol, protection valves and extra insulation, and the maths gets complicated. Here, January air rarely goes anywhere near zero, so that whole chapter of heat pump anxiety more or less disappears. Valencia homeowners get to pick between monobloc and split on the merits that actually matter locally: where the unit physically fits, how far the water has to travel, and how the comunidad feels about the façade. We still fit frost protection as good practice — we just never let it drive the design, and that freedom is a quiet local luxury.

Air-to-Water Heat Pumps
Valencia FAQ
What is the difference between an air-to-water heat pump and normal air conditioning?
A standard split AC is air-to-air: it blows warm or cold air into the one room it hangs in. An air-to-water heat pump heats or chills water instead, and that water feeds underfloor loops, radiators, fan coils and your hot water cylinder. One outdoor unit quietly runs the whole house rather than blasting air at a single sofa.
+
Should I choose a monobloc or a split hydronic unit?
A monobloc keeps the entire refrigerant circuit in one outdoor box, so installation is simpler and no refrigerant work is needed on site — ideal where a terrace or garden sits close to the house. A split hydronic system runs refrigerant lines to an indoor module, which helps when the outdoor unit must sit far from your plant room. We look at your building first and then recommend one, with the reasons in writing.
+
Do monobloc units need antifreeze in Valencia?
In colder countries the water inside a monobloc's outdoor pipes can freeze during a power cut, so installers add glycol or protection valves and the design gets complicated. Valencia's winters make that scenario extremely rare. We still fit anti-freeze protection as good practice, but here it is a small detail rather than a design headache.
+
Where does the outdoor unit go?
On a balcony or terrace for flats, on a flat roof with the comunidad's blessing, or on a garden slab or wall bracket for houses. We keep it away from bedroom windows and neighbours, mount it on anti-vibration supports, and keep the water runs short so the system stays efficient.
+
Can one air-to-water unit really handle heating, cooling and hot water?
Yes — that is the point of the technology. In winter it sends warm water to your floor or radiators, in summer it sends chilled water to fan coils or the floor loops, and all year round it keeps an ACS cylinder hot for showers and taps. One machine, one electricity bill, no gas contract.
+
How efficient is an air-to-water heat pump in Valencia?
Efficiency depends on the outdoor air temperature, and Valencia's mild winters are close to ideal. Modern units typically deliver three to four kilowatt-hours of heat for each kilowatt-hour of electricity in conditions like ours. The exact figure also depends on your emitters and settings, which is why we tune the heating curve during commissioning.
+
Do you install north of Valencia — Godella, Moncada, the huerta villages?
Yes, the northern corridor is core territory for us: Godella, Rocafort, Moncada and Alfara del Patriarca, plus the huerta villages of Meliana, Foios, Museros and Massamagrell, along with Almàssera, Vinalesa and Tavernes Blanques. If your town isn't on the list, message us anyway — we're rarely far away.
