Innovative Thin-Film Radiant Heater Elements

Program: ECT-NB
Priority Research Theme: Power Challenges Post 2030
Awarded: Winter 2026

Overview

Conventional radiant heating systems produced by ThermaRay Inc. (Fredericton, N.B.) rely on bulky components and external thermostats, which can reduce efficiency, complicate installation, and lead to uneven heat distribution. These challenges are compounded by the company’s dependence on imported heating elements, often supplied without complete electrical specifications—creating performance uncertainty and, in some cases, potential safety risks.

To address these issues and strengthen domestic capabilities, ThermaRay has partnered with the Thin Films & Photonics Research Group (GCMP) at the Université de Moncton. Using its expertise in nanotechnology, GCMP has developed a next-generation thin-film heater prototype designed for seamless integration into floors, ceilings, curved surfaces, and other complex structures. Early testing shows strong heating uniformity and promising scalability for large-area applications.

The goal of this project is to optimize the performance, stability, and energy efficiency of this thin-film radiant heater, which is based on Positive Temperature Coefficient (PTC) conductive materials. At the same time, the team will develop scalable coating and deposition processes to enable consistent, large-area manufacturing with controlled thickness, durability, and cost efficiency.

This work will allow ThermaRay to move from reliance on imported components to in-house production of advanced heating elements—improving product reliability, safety, and supply chain resilience.

Expected outcomes include a validated and scalable technology for producing flexible, lightweight, nanotechnology-based radiant heaters. These systems will offer improved energy efficiency, built-in safety through PTC self-regulation, and greater design flexibility across residential, commercial, and industrial applications.

Overall, the project will strengthen ThermaRay’s competitive position, support regional economic growth, reduce dependence on foreign suppliers, and advance clean, efficient, made-in-New Brunswick heating solutions for an electrified future.
