Warmth that wraps around you
Heat rises evenly from the whole floor, not from one spot. No cold zones, no cold feet and none of the dry air of radiators.
Underfloor heating · Mallorca
We're Joaquín and Juan. We've been installing underfloor heating across Mallorca together since 1998: warmth that rises evenly from the floor in winter; the cooling, with fan coils. Powered by aerothermal heat pumps to keep running costs to a minimum. A RITE-certified company: we install, repair and certify. Juan comes, Joaquín comes, or we both come — we never subcontract.

Why JSL
Comfort starts beneath the floor. What you see is a clean floor; what you feel is a warm, even home.
Heat rises evenly from the whole floor, not from one spot. No cold zones, no cold feet and none of the dry air of radiators.
In Mallorca the floor doesn't cool: with the summer humidity it would condense. The same heat pump delivers the cooling through fan coils, and the underfloor system gets on with what it does best, heating.
It works at a low temperature (35-40 ºC), exactly where aerothermal heat pumps perform best. The perfect pairing for a lean bill.
No units on the walls and no visible grilles. You gain space, freedom to decorate and a cleaner, quieter home.
As it doesn't move air, it doesn't stir up dust or dry out the room. A comfortable option for people with allergies and for homes with children.
Installations carried out and, where applicable, certified before the Industry authority under the RITE, with an invoice and the 3-year legal guarantee plus each manufacturer's warranty.
Before you decide
Beneath the flooring runs a network of pipes laid out in circuits. Low-temperature water circulates through them, spreading heat across the whole floor surface, and from there it rises naturally into the room. Here are the key points to decide wisely.
This is the system we install: circuit pipework on an insulating panel, manifolds that distribute water to each zone and a thermostat per room. Compared with radiators, it heats more evenly and at a lower temperature, so it uses less for the same comfort.
In summer the cooling doesn't go through the floor, it comes from fan coils, driven by the same aerothermal heat pump that heats the floor in winter. With Mallorca's summer humidity a cold floor would condense; a fan coil cools the air and takes moisture out of it as well.
Underfloor heating runs at 35-40 ºC, exactly the range where aerothermal is most efficient. That's why they go hand in hand: with a single machine you get heating through the floor, cooling through fan coils and hot water, harnessing the energy in the air and — if you add solar panels — running on your own sun during sunlight hours.
In new builds, underfloor heating is practically the standard. In renovations it's possible too: there are low-profile panels that raise the floor level by only a few centimetres, so you don't have to do more building work than necessary. We look at your case and tell you what fits.
How we work
You send us photos and details by WhatsApp or email; with them we see your home, measure rooms and needs and calculate the circuits. We recommend the right system and heat pump and give you a fixed quote. If we need to see it, we come.
We lay the insulating panel, circuits and manifolds, pressure-test everything and leave it ready for the screed and your flooring. Clean, well-finished work.
We balance the circuits, program the thermostats and show you how to get the most out of it. 3-year legal guarantee, each manufacturer's warranty, and maintenance if you want it.
What we do
From a complete installation to repairing a circuit that has stopped heating.
Water-based underfloor heating for new builds and renovations: panel, circuits, manifolds and thermostats, sized to your home.
Underfloor heating powered by an aerothermal heat pump: the floor heats in winter and fan coils cool in summer, all from one machine.
We repair circuits that won't heat and manifold faults in existing installations, and renew what has had its day, with a quote before acting.
Annual check of the manifold, valves and heat pump, circuit bleeding and water-quality control so it lasts for years, on top of whatever the RITE and the manufacturer require.
Real work
A real job we did ourselves: a home in Llucmajor fully climated with aerothermal underfloor heating. We laid the circuits across the whole floor, connected them to balanced manifolds and built the plant room with its heat pump, valves and thermostats.
The result: even warmth in winter and a home without a single visible radiator. All carried out and certified before the Industry authority under the RITE, with its documentation and warranty.
New build or fitting it into a renovation? We look at your case and propose what truly fits your home and your budget.
Real work
Circuits, manifolds and plant room from our own installations. Comfort starts beneath the floor.
Each circuit leaves the manifold balanced and pressure-tested.
Pipework spread across the whole living room before the screed.
The layout reaches every room to leave no cold zones.
The perimeter edge strip prevents thermal bridges and cracks.
Each room has its own circuit and valve, so it can be balanced and controlled separately.
Each zone at its own temperature, stable and efficient.
Before the screed goes down we leave the system under pressure with the gauge in front of us: if there were a leak, it shows up now and not under the floor.
Common questions
Hydronic underfloor heating is a pipe network beneath the floor finish, usually supplied with water at about 35-40 °C. That low flow temperature suits a heat pump; in Mallorca we size the loops, insulation and finish for each room. Technical source: IDAE guide to heat pumps in renovation.
No. In Mallorca we never cool through the floor: with the summer humidity, a cold floor condenses and gets wet. AEMET's normal values for Palma Airport show high monthly relative humidity, while Spain's RITE uses summer design conditions of 23-25 °C and 45-60% relative humidity. So the underfloor system works in winter and the cooling comes from fan coils, fed by the same heat pump. Sources: AEMET and RITE (BOE).
In Mallorca the price depends on usable m², loop count, insulation, floor finish and whether it is a new build or renovation. The emitter system does not necessarily include the heat pump, screed or finishes; we give you a fixed price from your photos and details.
Yes, but door clearances, steps and finished levels must be measured. Low-profile systems used in Mallorca renovations can raise the floor by only a few centimetres; the exact build-up depends on panel, pipe, screed and finish and is checked against UNE-EN 1264 system data before specification.
Tile, stone and other conductive finishes generally transfer heat well; wood can be used if its manufacturer approves it for underfloor heating. In Mallorca we check the thermal resistance of the complete build-up and adjust the flow temperature, commonly around 35-40 °C, to the chosen finish.
The concealed loops need little direct intervention, but the heating system still needs the maintenance specified for its equipment and applicable programme. In a Mallorca home we check the manifold, valves, pressure, venting, water quality and heat pump; Spain's RITE regulates maintenance and requires access for cleaning, servicing and repair.

It has more thermal inertia than a radiator, so response can take several hours depending on screed, flooring, insulation and flow temperature. In Mallorca we set schedules and weather compensation for stable low-temperature operation, commonly around 35-40 °C, without promising the same warm-up time for every home.

On its own, without a heat pump, there is no specific grant. With a new heat pump, yes: the Balearic Government's FACTOR 2026 call counts underfloor heating as a new distribution system, and the eligible cost rises from at most €1,000 to €1,450 per kW of heating output of the heat pump, with a 70% grant for individuals resident in the Balearics and a cap of €25,000 per installation. And if it is your main home or a home you let, and its energy certificate improves by what the law requires, it may also qualify for the income-tax (IRPF) deduction for energy-efficiency improvements (additional provision 50 of the IRPF Act), with one certificate before the work and another after. We prepare the paperwork and, with your authorisation, file and justify the grant; you sign the application and the grant is paid into your bank account. Source: BOIB no. 83, 2 July 2026.
