ThermaCurve mounted at the wall-ceiling junction of a modern room, almost indistinguishable from the coving
Coving & Corner Heating

Heating that lives where furniture doesn't.

ThermaCurve is an electric far infrared heater that mounts at the wall-ceiling junction like a piece of coving, or vertically in the corner of a room. Up and out of the way, safe from knocks and liquids, and a natural fit for rooms where every inch of wall and floor is already in use.

Where it goes

For rooms that have run out of wall space.

Panel heaters need a clear stretch of wall. Skirting heating needs a clear run at floor level. Some rooms have neither. Fitted wardrobes, floor-to-ceiling bookshelves, bay windows with built-in seating, compact studies, tiny bedrooms. ThermaCurve solves that by mounting in the one place nothing else is using: the top corner of the room.

Fitted horizontally, it looks like a piece of coving running the length of the wall. Fitted vertically, it tucks into the corner from floor to ceiling. Either way it's up and out of the way, doesn't steal any useable space, and is well clear of children, pets, and anything that might get kicked, spilled or leaned against.

How it works

Far-infrared, directed downward into the room.

An aluminium polymer profile houses a fire-safe heating cable on the rear face. Switch it on, and within moments the whole front face gives off far-infrared radiant heat, warming walls, floors and people directly rather than heating the air and letting it rise into the ceiling.

The curved geometry of the profile projects that warmth in a broad 90–180° beam, spread across the full length of whichever wall it's mounted on, often the entire room perimeter in a small space. That's a completely different experience from a point-source panel heater blowing hot air in one direction, or an overhead panel beaming down onto your scalp.

Safe by design

Out of reach, out of mind.

Panel heaters rely on a thermal fuse to stop themselves overheating if something gets draped over them. ThermaCurve's Fire Sure™ element uses a self-regulating cable that physically can't exceed its maximum temperature, even fully covered. Combined with an out-of-reach mounting position and a robust, earthed aluminium shell, it's a safer answer than a panel heater in any room with children, pets, or a real-world amount of furniture.

Safety & Lot 20 compliance

PTC element with intrinsic temperature limit.

The Fire Sure™ heating element is a PTC (positive temperature coefficient) cable: electrical resistance rises with cable temperature. At any point along the run where heat is being trapped (draped soft furnishings, fitted curtains or a covered section) local resistance increases and current draw at that point is throttled at the conductor itself. The element cannot exceed its rated maximum temperature anywhere along the run. There is no thermal fuse in the safety chain and no ignition path from items resting against the profile.

ThermaCurve is CE marked to EN 60335 (LVD) and meets the appliance-side requirements of Lot 20 of the EcoDesign Directive. It is Lot 20 compliant when paired with any qualifying control set (24/7 programming, open-window detection and adaptive-start controls). Heatmiser, Drayton Wiser, Hive, Nest and Tado all have qualifying control sets. The optional Eco-Start PCB controller adds gentle ramp-up and proportional power modulation, reported to deliver up to 40% energy reduction against an equivalent thermostatically-switched on/off panel heater.

Two versions

Standard or Low-Surface-Temp.

Even though it's well out of harm's way, the same profile is available in a standard version (130 W/m, surface temperature 65–75°C) and a Low-Surface-Temp version (65 W/m, surface temperature around 43°C) for where the vertical corner profile is used in nurseries or special-needs schools.

ThermaCurve profile render. The same profile is used for the standard and the low-surface-temp version.

The profile is identical for both versions. Pick the standard for most rooms; pick the LST where the surface needs to be touch-safe.

What it actually looks like on the wall.

ThermaCurve blends seamlessly as an architectural detail, a slim band of coving near the ceiling or a subtle vertical panel in the corner. Most visitors will never register it as a heater at all.

How it compares

ThermaCurve vs the usual options.

Panel heaters, electric underfloor and ceiling radiant panels are all valid electric heating choices, they just come with trade-offs ThermaCurve doesn't have. Here's the side-by-side.

FeatureThermaCurveElectric panel heatersCeiling radiant panels
Wall & floor space usedNone. Mounts up at the ceiling or tucks into a corner.Takes a full stretch of clear wall.None, but often clashes with lights and services.
Heat distributionBroad 90–180° radiant beam across the whole wall.Hot air blown from a single point, rises to the ceiling.Downward beam directly above occupants.
Response timeFast. Warms objects and people almost immediately.Fast air-side, slow to feel comfortable.Fast overhead, but can feel oppressive.
Fire safety if coveredSelf-regulating cable physically can't overheat.Relies on a thermal fuse; ignition risk from draped fabric.Low risk, out of reach.
Overheating / comfortBroad, gentle infrared. No hot spots.Prone to hot-cold zoning in the room.Can trigger discomfort or distress if directly overhead.
Install impactDry install, push-fit connections, no plumbing.Dry but needs fused spur behind the unit.Needs ceiling void, strengthening and careful service coordination.
AestheticReads as coving or an architectural corner detail.Visible white box on the wall.Usually a surface-mounted panel overhead.
Installation

Up on the brackets, clip shut, switch on.

ThermaCurve is a one-trade install: an electrician runs a fused spur to the room (usually on a dedicated ring main), brackets go on the wall, the profile snaps onto them, and it's done. No plumbing at any stage, and most rooms are finished in a day.

Frequently Asked Questions

Everything you need to know

Where exactly does ThermaCurve mount?
Two options: horizontally, at the junction between wall and ceiling (the way coving sits), or vertically, tucked into the corner between two walls from floor to ceiling. Both put the heater up and out of the way, free of furniture and out of reach of kicks, spills and leaning furniture.
Is it better than a standard panel heater?
For the spaces ThermaCurve is built for, yes. Panel heaters take up a full stretch of clear wall, concentrate their heat in one place, and rely on a thermal fuse to stop themselves overheating if covered. ThermaCurve sits out of the way, spreads radiant heat across the whole length of the wall, and uses a self-regulating Fire Sure™ cable that physically can't overheat. In a small or fully-furnished room, it also just looks better, an architectural detail rather than a white box.
Is it better than electric underfloor heating?
They do similar jobs but react differently. Electric UFH is hidden and lovely to walk on, but it's slow to respond, held back by thick rugs or heavy furniture, and a nightmare to retrofit without lifting the floor. ThermaCurve installs in a day without touching the floor, responds in minutes rather than hours, and cools quickly when the room gets too warm, which is often an issue in well-insulated modern rooms that UFH tends to overshoot.
Is it better than a ceiling radiant panel?
For most home rooms, yes. Ceiling panels project heat directly downward onto whoever's beneath them, which many people find oppressive and which can trigger distress in children and anyone with sensory sensitivity. Ceiling panels also fight for space with downlights, alarms, fire detection and other services, and usually need local strengthening. ThermaCurve fixes to the top of the wall with conventional plugs and screws and projects its warmth outward into the room rather than down at you.
How efficient is it?
100% efficient at the point of use, every watt of electricity becomes heat in the room. With the optional Eco-Start PCB controller it's cleverer than that: it ramps up gently over the first five minutes, then spends most of its time hovering at half-power or off rather than flipping fully on and off. In tests, Eco-Start kept the system in half-power or off for 80% of the programmed run time, while holding the room at 21°C.
Will it work with Hive, Nest, Tado and other smart thermostats?
Yes. ThermaCurve switches on and off with any 16A-rated thermostat, which covers every major smart control: Hive, Nest, Tado, Drayton Wiser, Heatmiser. You get full scheduling and room-by-room zoning.
Is it safe to have close to children or in a nursery?
The Low-Surface-Temp (LST) version is built specifically for when installed vertically in a corner, in areas where LST is a requirement. It runs at around 43°C on the front face, so it's safe to touch even for occupants with sensory deprivation. If mounted at coving level, it's a much safer option than a standard panel heater in any child's room, nursery or care setting.
What if something gets pushed up against it or draped over it?
It self-regulates. The Fire Sure™ heating cable physically can't exceed its maximum temperature. Where most panel heaters rely on a single thermal fuse to stop a fire if something gets draped on them, ThermaCurve can't start one in the first place.
What colour is it?
As standard it's powder-coated semi-gloss in Cricket White (RAL 9010). It can be ordered in any RAL colour to match the wall or ceiling, which is what most homeowners do. The whole point is for it to read as part of the architecture rather than an object.
How long does a length come in?
Lengths are cut to your room, up to 6 metres as a single profile. Where a run needs more than that, sections join together with push-fit connections, so there's no soldering or sealant on site.
Does it need servicing?
No. There's no pipework to bleed, no fan or filter to maintain, and no consumable parts. Once it's installed, there's nothing to do.
What's the warranty?
Five years on the heating element. The aluminium profile itself has no moving parts and is built to outlast the building.
