Aerotermia with Radiators
and Fan Coils in Valencia
Not every home needs its floors dug up to enjoy a heat pump. If your house already has a radiator circuit — or you want emitters that can blow cool air in August as well as warm it in January — we build the aerotermia system around what makes sense: low-temperature radiators where they earn their place, fancoils where cooling matters, and an honest verdict on every panel you already own. The quote is fixed and written before we start, and a 2-year workmanship warranty covers everything after.
Aerotermia con Radiadores y Fancoils
Your Radiator Circuit
Is an Asset, Not a Problem
The pipes buried in your walls already know how to move heat around the house — they have been doing it for decades. A heat pump just asks them to carry gentler water, and the question becomes which emitters at the end of those pipes can work with it. That is a measuring job, not a demolition job.
So we measure. Every panel gets its output calculated at heat-pump temperatures; the ones that pass stay, the undersized ones are swapped for low-temperature models, and where you want summer cooling we fit fancoils on the same circuit. The result is a full aerotermia conversion with the building work kept to a minimum.

How a Radiator Conversion Works
Six Steps from Old Caldera
to Low-Temperature Comfort
Connecting a heat pump to the wrong emitters is how aerotermia earns an unfair bad name. Our sequence is built around one idea: measure the radiators you own before deciding anything else.
Step 1
Room-by-Room
Audit
We measure every radiator and check its real output at heat-pump water temperatures.
Step 2
Emitter Plan
& Price
A keep-or-upgrade verdict for each room, itemised in one fixed written quote.
Step 3
Heat Pump
Goes In
Outdoor unit and hydraulic module installed and tied into your existing circuit.
Step 4
Radiators
& Fancoils
Undersized panels swapped for low-temperature models; fancoils fitted where you want cooling.
Step 5
Flush, Fill
& Wire
The circuit is flushed clean, refilled with inhibitor and wired to a protected supply.
Step 6
Balance
& Tune
Every emitter balanced, the heating curve matched to your panels, controls explained.

Fancoils para Aerotermia
Homes Where Radiators and Fancoils Shine
The south metro is full of houses built around a radiator circuit — and increasingly full of owners who also want cooling. These are the six situations we get asked about most.
Flats That Want Cooling Too
Fancoils give a city flat winter warmth and summer cool without stacking splits on the façade.
Homes That Can't Lose Their Floors
Finished interiors, hydraulic tiles, no appetite for works — emitters that reuse what's there.
Bedrooms That Need Quiet
Low-temperature panels and whisper-mode fancoils for rooms where silence is the spec.
Mixed-Emitter Layouts
Radiators in bathrooms and halls, fancoils in living spaces — each room gets the right tool.
Older Village Houses
Thick-walled homes in Picassent or Silla where generous old panels often pass the audit.
Keep What Works
Aerotermia with Radiators: Most Panels Can Stay
Cooler Water, Bigger Surface, Same Comfort
A gas caldera shoves water around the house at 60–70 °C because it can. A heat pump earns its efficiency at 35–50 °C — and the cooler the water it has to produce, the less electricity it uses. The job, then, is not to replace every radiator but to find out which of yours can deliver comfort at those gentler temperatures. In a typical Valencia townhouse, the honest answer is: more of them than you'd expect.
- ✓ Output of every panel calculated
- ✓ Keep-or-upgrade verdict per room
- ✓ Low-temperature models where needed
- ✓ Existing pipework put back to work
- ✓ Full flush before connection
- ✓ Magnetic filter protects the pump
- ✓ Balancing so no room lags behind
- ✓ Heating curve tuned to your emitters

Fancoils: The Emitter That Works Both Seasons
Warm Air in January, Cool Dry Air in August
A fancoil is what you get when a radiator learns new tricks: warm air on demand in winter, chilled dry air in summer, all fed by the same aerotermia unit outside. Wall-mounted models resemble a modern AC split; console versions sit where a radiator once stood; ducted ones vanish into a false ceiling. If you're choosing emitters during a renovation — or simply refuse to sweat through another Valencian summer — this is the one that does both jobs.
- ✓ Wall, console and ducted models
- ✓ Heats a room in minutes
- ✓ Cools and dehumidifies in summer
- ✓ Quiet low-speed night settings
- ✓ Individual control per room
- ✓ Condensate drains routed cleanly
- ✓ Happy alongside existing radiators
- ✓ One outdoor unit feeds them all

Radiator and Fancoil Conversions Across Horta Sud
Based in Torrent — Your Town Is Minutes Away
Our base in Torrent makes the towns of l'Horta Sud neighbours rather than a trek: Paiporta, Picanya and Benetússer are a few minutes out, and the string of towns down the V-31 — Catarroja, Massanassa, Albal, Beniparrell, Silla — is territory our vans cover daily. Much of the housing here is exactly what this service was made for: two- and three-storey family homes with a gas caldera and a radiator in every room, ready to change fuel without changing pipework. Further inland in Picassent, where plots grow bigger and homes stand detached, we tend to add fancoils for summer cooling alongside the panels that pass the audit.

Local Insight
Oversized for Gas Is Right-Sized for Aerotermia
There's a quiet advantage hiding in many Valencian radiator circuits: because serious cold is rare here, the original installers often fitted generous panels that spend their lives loafing along at half output. A panel with spare surface can match its old gas-era comfort on much cooler water — which is precisely what a heat pump wants to supply. It's why our audits in Horta Sud townhouses so often end the same way: keep most of them, swap two or three, and spend the difference on a fancoil for the summer.

Radiators & Fan Coils
Valencia FAQ
Can aerotermia really run my existing radiators?
Usually a good share of them, yes. A heat pump sends out cooler water than a gas boiler, so each panel needs enough surface area to deliver the same warmth. During our audit we measure every radiator, calculate its output at heat-pump temperatures and give you a room-by-room verdict: keep, upgrade, or add a fancoil.
+
What makes a radiator 'low-temperature'?
Mostly surface area. Low-temperature models pack in extra panels and fins so they can shed the same heat from 45 °C water that an old single panel needed 70 °C to deliver. They look much like normal radiators, fit the same wall positions and connect to the pipes you already have.
+
What exactly is a fancoil?
A fancoil is a slim unit — wall-mounted, floor-standing or hidden in a false ceiling — with a water coil and a quiet fan. In winter it blows warm air within minutes of switching on; in summer the same unit runs chilled water and cools the room. It is the emitter we suggest when a home wants heating and cooling from one aerotermia system.
+
Will you have to rip up my floors?
No — that is the point of this approach. Radiators and fancoils use the pipe runs already in your walls, or short new runs we chase in and make good. It is the retrofit route for homes where underfloor heating would mean losing the floors, the doors and a month of your life.
+
Do fancoils cool as well as a normal air conditioner?
They cool the same way — moving air across a cold coil — so the room feels just as fresh, and the coil pulls humidity out of the air too. The practical difference is plumbing: each fancoil needs a small condensate drain, which we plan into the design from day one.
+
Do radiators feel different on a heat pump?
They run gentler and longer. Instead of blasting hot for an hour and going cold, the panels sit pleasantly warm for most of the evening, and room temperatures stay steadier. Most clients tell us the house feels more evenly heated than it ever did on gas.
+
Can I mix radiators in some rooms and fancoils in others?
Yes, and it is often the smartest layout: fancoils in the living room and bedrooms where summer cooling matters, radiators in bathrooms and hallways where they already do the job. We separate the circuits hydraulically so each emitter type gets the water temperature it works best at.
+
Which towns south of Valencia do you work in?
All of Horta Sud is close to our Torrent base: Paiporta, Picanya, Benetússer, Sedaví, Alfafar, Massanassa, Catarroja, Albal, Beniparrell, Silla and Picassent, plus Valencia city itself. If your town is not on the list, message us anyway — we are rarely far.
