Underfloor Heating Systems

Complete Underfloor Heating, One Factory Source

SunAura builds every layer of an electric underfloor heating system in one Qingdao factory: the heating element, the thermostat that controls it, and the installation accessories that hold it together. That means one specification, one warranty and one engineering team behind your floor — whether you are heating a single bathroom or a whole apartment building.

This category brings together our graphene heating film (ultra-thin far-infrared film for dry installations), electric heating mats (self-adhesive 160 W/m² mats for tile and stone), double-conductor heating cables (for screed, pipe antifreeze and snow melting), tile-floor and wood-floor system pages, and our 0.5 mm aluminium-film renovation mats for height-constrained refurbishments. Every element pairs with a SunAura thermostat from our Thermostats & Controls category.

How to Choose the Right Floor System

1. Graphene Heating Film — dry, fast, low-profile

Film is the most popular choice for renovations without screed: it installs directly under laminate, engineered wood, LVT or carpet with a floating-floor construction, warms up in minutes and radiates comfortable far-infrared heat. Choose film when floor height is limited and you want the thinnest build-up.

2. Electric Heating Mats — best under ceramic and stone

Mats are pre-spaced on a self-adhesive mesh, rated 160 W/m², and designed to be embedded in thin adhesive before tiling. They suit bathrooms, kitchens, entryways and anywhere porcelain or natural stone is the final floor.

3. Heating Cables — flexible for screed and specialist jobs

Single-run cables give installers maximum layout freedom in wet screed, and our double-conductor construction with IPX8 insulation also handles pipe antifreeze, roof and ramp snow melting, and equipment insulation.

4. Aluminium-Film Mats — the renovation specialist

At just 0.5 mm, aluminium-film mats fit where nothing else does: over existing floors, under laminate and engineered wood, in apartments where screed is not possible.

Energy Efficiency & Running Cost

All SunAura elements run at better than 99% electrical-to-heat conversion. Because radiant heat warms people and objects first, a room feels comfortable at a lower air temperature — typically saving 15–30% compared with convective heating. Combined with a weekly-programme thermostat and room-by-room zoning, you only heat the spaces you actually use, when you use them.

Installation & Safety

Every system page in this category includes step-by-step installation guidance, wiring diagrams and recommended insulation. Elements are IP67/IPX8 rated where relevant, EMF-free in normal operation, and carry CE and RoHS compliance. We supply complete DIY installation kits and our engineers support installers by WhatsApp during commissioning.

Quality & Warranty

SunAura has manufactured electric heating products since 2008, with in-line testing on every batch. Heating mats carry a 25-year structural warranty; film, cable and aluminium mats are covered by the product warranty with direct factory after-sales support in English, German, French and Chinese. OEM/ODM branding and custom dimensions are available for distributors.

FAQ

1. Can I install SunAura film under my existing floor?

Yes — graphene film and aluminium-film mats are designed for floating installations over existing subfloors. The aluminium-film mat at 0.5 mm is the thinnest option for renovation projects.

2. Do I need a thermostat with the heating element?

Every electric heating system needs a thermostat to regulate temperature and protect the floor. We recommend a SunAura thermostat matched to your load — see Thermostats & Controls for WiFi, touch, knob and RF options.

3. What is the running cost per square metre?

It depends on insulation, climate and programme. As a rule of thumb, a well-insulated room heated with film at 25 W/m² average running power costs roughly one-third of continuous full-power heating. Use the weekly timer to cut costs further.

4. Are these systems safe for bathrooms?

Yes — heating mats and cables rated IPX7/IPX8 can be installed in wet areas under the tiling, with the thermostat placed outside the splash zone and wiring carried out by a qualified electrician.

5. Can I order custom sizes?

Film is available in widths from 10 cm to 100 cm and any custom length; mats and cables are supplied in fixed kits with cuttable cable runs. Tell us your floor plan when ordering for a free layout and sizing.

Factory-Backed Quality: 17 Years, ISO and EU Compliance

Every SunAura system is manufactured at the Qingdao Huangdao factory, where the company has produced heating elements since 2008 — 17 years of continuous manufacturing. The factory operates under ISO 9001 (quality), ISO 14001 (environment) and ISO 45001 (occupational health and safety), and the product range carries CE, RoHS, LVD and EMC compliance for the European market. Products are exported to more than 50 countries, and each shipment leaves with the batch record and the compliance file, so a buyer can trace any film, mat or cable back to its production batch.

Underfloor Heating Systems for Apartments, Villas & Renovations

Whether you are outfitting a new-build apartment, a multi-room villa, or refurbishing a floor where screed is impossible, choosing the right element is what makes the project comfortable and economical. For dry-build apartments and villas finished in laminate, engineered wood, LVT or carpet, graphene heating film delivers a low-profile, fast-response radiant system that warms up in minutes and sits neatly under a floating floor build-up. For bathrooms, kitchens, entryways and any wet room finished in porcelain or natural stone, electric heating mats remain the proven choice — pre-spaced on a self-adhesive mesh and embedded in thin tile adhesive.

Where floor build-up is tight and the subfloor cannot be raised, our 0.5 mm aluminium-film renovation mats let you add radiant heat over an existing floor without major structural work. Long-run and specialist jobs — pipe antifreeze, roof and ramp snow melting, and equipment insulation — are covered by our double-conductor heating cables. Every element in this category is designed to work as one matched package with a SunAura controller, so you can design whole-apartment zoning, bathroom-only comfort heating, or a villa-wide system from a single specification and one engineering contact. Compare the graphene heating film range, the electric heating mat kits, and the aluminium-film renovation mats to check thickness, output and floor build-up before you specify.

How to Buy: Wholesale, Bulk & OEM

SunAura sells underfloor heating elements factory-direct to distributors, installers, contractors and online retailers. We welcome wholesale price enquiries for film, mats, cables and renovation mats, with bulk discounts that scale with your order volume. MOQ and pricing depend on model, width and quantity — send us your room sizes or product list and you will receive a same-day quotation. Typical lead time is 15–30 days for production orders after sample approval, and we offer free samples (freight collect) for qualified trade customers so you can verify film thickness, mat adhesive and cable feel before committing.

Our OEM/ODM and private-label programme runs across the whole range: custom film widths and lengths, printed branding on mats, coloured retail packaging and pre-matched thermostat options. We export on EXW and FOB Qingdao terms and supply CE, RoHS and compliance documentation with every shipment. For drop-shipping and e-commerce retail packaging, tell us your target market and we will propose the right model mix. Contractors running whole apartment projects can bundle elements and thermostats into one shipment with a free layout and sizing service.

We also supply the accessories installers reorder most — insulation underlay, aluminium tape, fixing clips and sensor extensions — alongside the main elements, so a repeat order never waits on a production run. Whether you are a one-room DIY installer or a contractor fitting a whole apartment block, the same factory support and layout service applies.
