This case study examines a residential villa heating project completed by SunAura Thermal in collaboration with a local installation partner. The project, located in a premium residential development, involved the installation of graphene underfloor heating throughout a 300-square-meter villa, demonstrating the capabilities of our products in a luxury residential setting.
Project Overview
The villa, a newly constructed two-story residence, required a comprehensive heating solution that would provide consistent comfort across all living spaces while maintaining the aesthetic integrity of the interior design. The homeowner, a family of four with young children, prioritized safety, energy efficiency, and the ability to control the heating system remotely. The project encompassed six heated zones: living room, dining room, kitchen, master bedroom, children bedrooms, and four bathrooms.
System Design
The heating system was designed using SunAura Thermal graphene heating film with a power density of 220W/m2 for bathrooms and 150W/m2 for living spaces. The total heated area was 240 square meters, representing 80% of the total floor area. The system was divided into six independent zones, each controlled by a SunAura Thermal WiFi thermostat with floor temperature sensing. This zoning strategy allows the family to heat only the rooms in use, maximizing energy efficiency.
The graphene heating film was selected over traditional water-based underfloor heating for several reasons. First, the ultra-thin profile (0.4mm) meant minimal floor height increase, which was critical for the renovation project where ceiling heights were already constrained. Second, the rapid heat-up time (3-5 minutes) was attractive to the family, who preferred on-demand heating rather than continuously operating systems. Third, the zero electromagnetic radiation was a key factor for the family with young children.
Installation Process
The installation was completed over 5 days by a team of three installers. The process began with subfloor preparation, ensuring all surfaces were clean, dry, and level. Six-millimeter XPS insulation boards were installed over the entire floor area, with joints taped with aluminum tape to create a continuous vapor barrier. The graphene heating film was then laid out according to the design plan, with careful attention to maintaining consistent coverage and avoiding overlaps.
Electrical connections were made by a licensed electrician, with each zone wired to a dedicated circuit protected by a 30mA RCD. Floor temperature sensors were installed in conduit tubing positioned between heating film runs. The WiFi thermostats were mounted at 1.5 meters height in each zone, with the master bedroom thermostat serving as the system controller. After electrical testing confirmed all circuits were functioning correctly, the laminate flooring was installed by the flooring contractor.
Performance Results
After commissioning, the system was monitored for 12 months to evaluate performance. The results exceeded expectations. The average energy consumption was 4,200 kWh for the heating season (October to April), representing a 35% reduction compared to the projected consumption of a traditional electric heating system. The rapid heat-up time allowed the family to use setback temperatures of 16 degrees during unoccupied periods, with the system reaching comfort temperature within 5 minutes when activated.
The WiFi thermostats provided the family with complete control over the heating system from their smartphones. The mother particularly appreciated the ability to pre-heat the bathroom floor before her morning routine, and the father valued the energy monitoring feature that allowed him to track consumption and optimize the heating schedule. The geofencing feature automatically adjusted the heating when the family left for or returned from school and work.
Client Feedback
The homeowner provided overwhelmingly positive feedback. They reported that the heating was more comfortable than any system they had previously experienced, with even, gentle warmth that permeated the entire space without the dry air associated with forced-air systems. The floor temperature in the bathrooms was particularly appreciated, providing a luxurious comfort experience. The energy bills were significantly lower than expected, and the smart control features exceeded their expectations.
Conclusion
This 300-square-meter villa project demonstrates the capabilities of SunAura Thermal graphene heating film in a premium residential application. The combination of rapid heat-up, energy efficiency, smart control, and safety features provided the family with a heating system that exceeded their expectations in every aspect. The project serves as a reference for future luxury residential installations and highlights the advantages of graphene heating technology over traditional heating solutions.
