Carbon fibre wall heating is the thinnest, fastest-installed and most solar-friendly way to warm a home in South Africa. Synergy designs, installs and commissions complete 48 V DC systems nationwide, saving homeowners up to 90% on heating costs when paired with a solar PV installation, and working invisibly behind any standard wall or ceiling finish.
Book a Free Site Assessment See How It WorksSynergy Energy Solutions installs carbon fibre wall and ceiling heating across South Africa from three branches: Centurion (Gauteng HQ), Cape Town (Western Cape) and Polokwane (Limpopo). All branches share one phone number, 010 601 6464. Whole-home systems start from approximately R1 150 per square metre, save 50 to 90% on heating costs, and couple directly to solar hybrid inverters. SAPVIA-aligned, PV GreenCard accredited, ECA-affiliated. Installed to SANS 10142 electrical standards using safe 48 V DC, with Certificate of Compliance issued on every job.
Carbon fibre wall heating uses a patented conductive carbon film bonded to the wall or ceiling surface. A safe 48 V DC current passes through the film, which radiates infrared warmth directly into the room, like sitting in winter sunshine. There are no hot elements, no fans, no ducts and no moving parts. The film disappears behind plaster, paint, tiles, wallpaper or Rhino-lite, making it the only heating system that truly leaves your interior design untouched.
Who this suits best: homeowners retrofitting older homes without lifting floors, sectional-title flats where structural work isn't permitted, solar-first builds, families with asthma or dust allergies, and anyone tired of noisy aircons, gas fumes or oil heaters. If you're building new on a slab and want toasty feet on tiles, hydronic underfloor heating may suit you better, we install both and will recommend honestly.
The Synergy difference. Every system is engineered room-by-room: we calculate heat loads, map panel layouts, confirm your inverter's DC capacity and select the panel coverage and thermostat zoning sized for your actual living patterns, not a one-size-fits-all package.
A single system delivers comfort, dramatic energy savings, healthier indoor air and total design freedom, without the noise, dust, ducting or running costs of traditional heating, and with no floor lifting required.
Carbon fibre radiates infrared warmth directly into the room with zero downward loss and zero ducting loss. Running cost is 50 to 90% lower than conventional electric heating, and effectively zero on sunny winter days when coupled to your solar PV.
Radiant heat doesn't blow dust, pollen or pet dander around the room, a meaningful comfort upgrade for households with asthma or allergies, particularly in pollen-heavy Gauteng and Cape Town winters.
Schedule heating per zone, monitor runtime and tweak temperature from your phone. Wi-fi thermostats integrate with modern smart-home platforms and with Synergy's solar monitoring, so you only heat rooms when they're used.
The thin carbon film disappears behind plaster, paint, tiles, wallpaper or Rhino-lite. No radiators, no bulky heaters, no visible ducting and no floor build-up, the only heating system that truly leaves your interior untouched.
Runs natively on 48 V DC. Couples directly to Victron, Sunsynk, Sigenergy and Tesla Powerwall 3 hybrid inverters, no extra inverter losses. Your solar generation heats the home in real time, and a modest battery covers load shedding.
48 V DC is below the SANS 10142 shock-hazard threshold. No exposed elements, no hot surfaces, no fans, no moving parts. Safe to install behind a child's bedroom wall, and completely silent in operation.
Every carbon fibre wall heating system we install is built from five precision components, each chosen for reliability in South African conditions and certified for solar-direct operation.
The radiant heart of the system. The 0.3 mm film bonds directly to the wall or ceiling substrate; total installed build-up including the finish layer is approximately 1 mm.
The transformer is what makes the system safe and code-compliant. When you have a hybrid inverter, the transformer becomes a backup, the inverter feeds the panels DC-direct.
When connected to a solar hybrid inverter, daytime solar power feeds the heating directly, effectively free heat. Overnight, a modest battery bank covers low-draw heating cycles.
From simple dial thermostats to fully programmable wi-fi controls. Set schedules, create scenes and monitor energy use from anywhere, so you only pay to heat occupied rooms.
Every Synergy install is technician-installed and electrician-certified, with a Certificate of Compliance issued on every job, protecting your home insurance and the resale value of the property.
The carbonic film element ships at 0.3 mm thick. Once Synergy bonds it to your wall or ceiling and your plasterer or tiler covers it, the total installed build-up is approximately 1 mm, thin enough to disappear behind any standard finish, anywhere in the home.

Retrofit or new build? Carbon fibre is the rare heating system that suits both. For new builds we typically install on ceilings before final plaster. For retrofits we install one room at a time on existing walls, then cover with fresh plaster or Rhino-lite, no floors lifted, no screed cure time, the home stays liveable throughout.
Every system Synergy installs uses the same independently certified carbonic film element, CE-marked, TÜV Rheinland certified, compliant with EU low-voltage and EMF safety directives, and backed by a 10-year manufacturer warranty.

The Carbonic Film Heating element installed by Synergy is independently certified by TÜV Rheinland and CE-marked for the European Union market. It complies with the following international directives and South African electrical standards:
What 220 W/m² means in practice. The rated power figure is the draw when the element is actively heating, roughly equivalent to a small hair dryer per square metre, but spread invisibly across the entire wall or ceiling. Under thermostat control in a well-insulated South African home, the panels heat the surface quickly, then cycle off, so the time-averaged draw is significantly lower than the rated figure.
Why 48 V DC matters. The element runs natively on 48 V DC, well below the SANS 10142 shock-hazard threshold, safe to install behind any standard wall or ceiling finish, including behind a child's bedroom wall. The DC input voltage also lets the element couple directly to the DC side of a hybrid solar inverter (Victron, Sunsynk, Sigenergy, Tesla Powerwall 3) with no double-conversion losses, so 99.97% of the solar electricity generated becomes radiant warmth in your home.
10-year manufacturer warranty. The Carbonic Film Heating element is backed by a 10-year factory warranty from the manufacturer, in addition to Synergy's installer warranty. With no moving parts, no compressors and no maintenance requirements, the expected service life in normal residential use is 25 years or more.
Every heating technology has a use case. Here's how carbon fibre wall heating stacks up against the most common alternatives in South African homes, honestly, including the trade-offs.
| Feature | Carbon Fibre Wall | Hydronic Underfloor | Electric Underfloor | Aircon "Heat Mode" | Gas / Oil Heater |

The honest answer. If you're building from scratch and laying floors anyway, hydronic underfloor heating is hard to beat. If you're retrofitting, want solar-direct heat, or care about preserving existing finishes, carbon fibre is the better fit. Synergy installs both and will recommend whichever genuinely suits your project.
We coordinate closely with your builder, plasterer and electrician to deliver a fully commissioned carbon fibre wall heating system in days, not weeks, without lifting a single floor or delaying any other trade.
Our technician visits your home to measure each room, assess wall and ceiling construction, confirm solar inverter compatibility (Victron, Sunsynk, Sigenergy or Tesla Powerwall 3) and recommend panel layout and thermostat zones. We also confirm whether the project is a retrofit or new build, that drives the install sequence that follows.
Zone-by-zone design, room-by-room heat-load calculations, solar-coupling potential analysis and a written, fixed-price quote with running-cost estimates. Panel coverage, transformer sizing, inverter coupling strategy and thermostat zoning are all locked down before any panel arrives on site.
Our specialist solar technicians bond the carbon fibre film panels to the wall or ceiling surface using specialised adhesive. A PV GreenCard accredited electrician then wires the panels into the 48 V DC circuit. The home stays liveable throughout, rooms are typically fitted out one at a time so daily life continues uninterrupted.
Your plasterer or tiler finishes over the panels. Paint, wallpaper, tiles, Rhino-lite or even decorative cladding can all be applied as normal, the panels add only about 1 mm of build-up and disappear completely behind any standard finish. There is no screed, no cure time and no floor lifting.
Thermostats are configured, the system is load-tested against the design, a Certificate of Compliance is issued, and we walk you through the app and schedule settings. From then on, our Centurion, Cape Town and Polokwane branches provide ongoing support for the lifetime of the system.
Cost per square metre depends heavily on heated area. Smaller systems carry a higher rate per m² because the transformer and controls remain similar in size regardless of heated area, larger systems spread those fixed costs across more wall and ceiling space.
Common request, but the cost per m² is the highest of any configuration. We'll happily quote it, and often recommend extending into adjacent rooms.
A good balance of comfort and budget, heat the rooms you live in, leave the rarely-used spaces unheated.
The lowest cost per m² for residential work, and the configuration that maximises solar-PV savings. Best long-term value for retrofits and new builds alike.
Guesthouses, lodges, retirement-village clusters, offices, churches, every commercial brief is designed and quoted individually after a site visit.
What drives the price? Heated area is the biggest factor, followed by panel coverage density (W per m²), the control system you choose (single thermostat vs multi-zone wi-fi smart controls), and whether you bundle a solar PV installation. Multi-zone smart controls add meaningful cost but typically pay for themselves quickly through reduced runtime, you only heat occupied rooms.
How does this compare to hydronic underfloor heating? On a like-for-like area basis, carbon fibre wall heating works out approximately 20% more than hydronic water underfloor heating per m², but it installs in days instead of weeks, doesn't require lifting any floors, and couples directly to your solar inverter. For most retrofits, the total cost of ownership is lower.
Pair it with solar to unlock the 90% saving. The pricing above covers the heating system only. To achieve the full up-to-90% running-cost saving, the system should be paired with a Synergy solar PV installation, which we quote separately. Many homeowners stage the project: solar first, then carbon fibre once the inverter is in place.
Ten of the most common questions we field from homeowners in Gauteng, the Western Cape and Limpopo. Don't see yours? Send it through and we'll answer personally.
For most South African homes, carbon fibre wall or ceiling heating is the most energy efficient option because it radiates heat directly into the room with no downward loss and no ducting losses. Typical running cost is 50 to 90% lower than conventional electric heating, and the system can be powered directly from a solar hybrid inverter, meaning on sunny winter days you pay Eskom nothing at all.
A low-voltage 48 V DC current passes through a thin carbon fibre film embedded behind the wall or ceiling finish. The film heats the surface, which then radiates warmth into the room, similar to sitting in winter sunshine. There are no moving parts, no fans and no hot elements that can be touched.
Yes. The system runs on 48 V DC, well below the 50 V AC shock-hazard threshold under SANS 10142. There are no exposed resistance wires and no hot surfaces. It is installed by our specialist solar technicians and certified by a PV GreenCard accredited electrician, with a Certificate of Compliance issued on every job.
In almost every case, yes. Most hybrid inverters sold in South Africa, Victron, Sunsynk, Sigenergy, Tesla Powerwall 3, can power the heating panels directly. Synergy will assess your current system, confirm capacity, and if needed retrofit a DC coupling to give you effectively free winter heat during daylight hours. See our solar PV range if you don't yet have a hybrid inverter installed.
Carbon fibre wall heating is priced per square metre of heated wall or ceiling area, and on a like-for-like area basis works out approximately 20% more than hydronic water underfloor heating. Whole-home installations typically run from approximately R1 150 to R1 800 per m², partial-home configurations from around R1 450 to R2 150 per m², and bathroom-only zones from about R1 800 to R3 100 per m² because transformer and controls costs stay similar regardless of area. These figures cover the heating system only, to achieve the full up-to-90% running-cost saving, the system should be paired with a solar PV installation, which we quote separately. A fixed written quote is provided after a free on-site assessment.
Both. The carbon film element is only 0.3 mm thick (approximately 1 mm total installed build-up with finish layer) and bonds to raw brick, plastered walls or painted surfaces. For retrofits we typically install one room at a time, covering the film with fresh plaster or Rhino-lite, then finishing with paint, tiles or wallpaper. Unlike hydronic underfloor heating, no floors need to be lifted and there is no screed cure time, the home stays liveable throughout.
Hydronic underfloor heating circulates warm water through pipes in the floor screed, ideal for new builds or major renovations, and excellent under tiled floors. Carbon fibre is thinner, faster to install, solar-direct, and works on walls or ceilings, making it the better fit for retrofits and solar-first homes. Synergy installs both and will honestly recommend which suits your project. Compare hydronic underfloor heating →
Most whole-home installations are completed in 2 to 4 working days, depending on room count and the plastering schedule. A single-room retrofit is typically finished in a day. Because there is no floor lifting and no screed cure time, the home stays liveable throughout.
Almost any standard wall or ceiling finish: fresh plaster, Rhino-lite, paint, wallpaper, tiles and even decorative cladding. The 0.3 mm carbon film bonds directly to the substrate, with total installed build-up of approximately 1 mm including the finish layer, completely invisible once the wall or ceiling is complete. There is no minimum cover thickness for paint or wallpaper finishes, and only a thin tile-adhesive bed for tiled walls.
Yes. Because the system runs on 48 V DC directly off a hybrid inverter and battery, it continues to heat your home during load shedding when paired with a battery-backed solar PV system. The panels are rated at 220 W per m² but cycle under thermostat control, so the time-averaged draw on a small heated zone is well below the rated figure, modest battery banks can cover several hours of load shedding, and far more efficiently than running a portable oil heater continuously.
Carbon fibre wall heating works best as part of a complete energy strategy. Pair it with a hybrid solar PV system, battery storage and heat pump water heating for maximum savings. We install hydronic underfloor heating, Tesla Powerwall 3, Sigenergy SigenStor and Deye & Sunsynk hybrid solar, so your entire home energy stack is designed and maintained by one accountable team.
If you're laying floors anyway, hydronic underfloor heating is hard to beat for new builds and major renovations.
Pair your heating with a solar PV system to unlock the full up-to-90% running-cost saving and load-shedding resilience.
