FAQ

Electric underfloor heating uses electric heating elements (film, mat or cable) installed beneath the floor surface. It produces radiant heat that warms the floor and rises evenly through the room — quiet, invisible and easy to control with a thermostat.

Heating film systems typically warm up within 15–30 minutes because the element sits close to the surface. Mats under tile warm within 30–60 minutes. Cable systems embedded in thicker screed take longer to reach temperature but hold heat longer.

Yes. SunAura products are double-insulated, shielded and EMF-free, tested to IEC 60335 and CE / RoHS compliant, and protected by thermostats with floor sensors that prevent overheating.

No. Electric underfloor heating has no moving parts, no filters and no boiler service. Once installed and commissioned, it is effectively maintenance-free for the life of the system — one of its biggest advantages over wet systems.

Running cost depends on room size, insulation and usage. As a rule of thumb, electric underfloor heating costs about $0.10–$0.20 per square metre per hour at full output. With good insulation and smart-thermostat scheduling, consumption can be reduced by up to 30%.

DIY installation is possible for heating film and mats using our installation kits and step-by-step guides. For safety and warranty, electrical connections should be made by a qualified electrician, and we recommend professional installation for large or complex projects.

Most flooring works: tile and stone give the best heat transfer, followed by laminate, engineered wood and vinyl. Carpet works but reduces efficiency because it insulates. Wood and laminate should respect the floor manufacturer’s maximum surface temperature (typically 27–28 °C).

The installed cost depends on the system type, floor build-up and your local electrician rates — film under laminate is the thinnest and fastest option, while cable in screed covers larger open areas. We return transparent manufacturer pricing on request, with no hidden markups: send your room sizes and floor type through our contact form and our sales team will reply within one business day. You can compare film, mat and cable options first on the underfloor heating collection page.

Yes — film under laminate is one of our most common installations because the film is only a few millimetres thick and sits neatly under 2–3 mm foam underlay. Keep surface temperature within the laminate manufacturer’s limit (usually 27–28 °C) and always run the included floor sensor beneath the film. See room-by-room install photos in the applications gallery, and pick up replacement sensors, junction boxes and cable from the underfloor heating accessories page.

Film: fastest warm-up, thinnest profile, ideal under laminate/wood and for renovations. Mat: self-adhesive 160 W/m² under tile and stone, 25-year warranty. Cable: for screed, wet rooms, pipe trace heating and industrial snow melting. Send us your project details and we will recommend the best fit.

SunAura smart thermostats support both electric floor sensors and boiler or hydronic valve actuators, with app scheduling, open-window detection and voice-assistant compatibility. A 16 A relay suits heating film and mats, while a 3 A or dry-contact model pairs with gas boilers and zone valves. Explore the full line on the thermostats and controls range, and read our buying guides on the blog for a step-by-step selection walkthrough.

Yes. Our graphene heating film is double-insulated, shielded to near-zero EMF, IP67 water-resistant and tested to IEC 60335 with CE and RoHS compliance; it reaches only gentle surface temperatures (typically 25–35 °C) controlled by a floor-sensor thermostat. Certificates and SGS test reports are available on request from the certifications page, and every batch ships with a QC PASS record from our Qingdao factory.

Yes — samples are available for evaluation. Sample cost is deducted from the first production order, and lead time for standard samples is 3–7 days after confirmation.

Absolutely — SunAura has manufactured heating film in Qingdao since 2008 and exports to 50+ countries, serving distributors, HVAC contractors and e-commerce resellers with tiered wholesale pricing. Standard film widths, custom cut lengths and private-label packaging are all supported, and evaluation samples ship within 3–7 days. Start the conversation on WhatsApp with our export team or request a price list through the contact page.

Yes. As the manufacturer, we offer OEM/ODM services across the whole range — custom widths, lengths, wattages, thermostats, branding, packaging and multilingual manuals. Minimum order quantities are flexible and samples are available.

MOQ is flexible — sample cartons are available for evaluation, and standard distributor MOQs are kept low enough for new partners to test the market. Lead time is 7–15 working days for stocked models and 20–30 days for custom private-label versions, depending on cable length and packaging. Browse the current smart thermostat catalogue for in-stock models, and pair them with self-adhesive heating mats for complete project quotes.

It is a straightforward four-step flow: send us your logo and packaging artwork, we produce engineering samples for approval, you confirm a pre-production run, then mass production begins — typically 20–30 days. OEM covers custom housing colours, firmware, app branding, multilingual manuals and retail boxes, supported by our in-house R&D team in Qingdao. Message our WhatsApp line with your target order volume, or discuss options on the thermostats and controls page.

We export to 50+ countries by sea, air and express (DHL/FedEx/UPS) with FOB, CIF and EXW terms. Payment is typically 30% deposit and 70% balance before shipment via T/T, or L/C for larger orders.

We support EXW Qingdao, FOB Qingdao, CIF and DDP to most major destinations, by sea, air or express courier (DHL/FedEx/UPS). DDP is popular with resellers who want a landed-price quote with customs duty handled, while EXW suits forwarders who prefer to book their own containers; payment is typically 30% deposit and 70% before shipment. Small-parcel items such as the pet and plant heating range ship easily by express, and our shipping guides on the blog walk you through the first-order process.

Heating mats carry a 25-year warranty, heating film 15 years, and other products 15–25 years depending on the line, covering manufacturing defects under normal use. Warranty cards ship with every order.
