This new construction project in Orangeville, Ontario, involved installing a complete electric radiant floor heating system into a sizable concrete slab addition. The client, ATP Electric LTD, sought a high-performance, energy-efficient in-floor heating solution to ensure the large, new 511 sq. ft. area, which would feature an exposed concrete floor finish, remained comfortable and warm year-round. WarmlyYours delivered a robust Slab Heat Cable system designed to be embedded directly into the new concrete pour, providing reliable, primary heat for the entire space and eliminating the cold shock of walking on concrete.

The Comfort Solution
ATP Electric LTD required an ultra-reliable electric radiant floor heating solution that could handle the high thermal mass of a large, newly poured concrete slab. The challenge was two-fold: not only was the space large (511 sq. ft.), but the exposed concrete floor finish is notoriously cold. Standard HVAC is often inefficient at heating from the ceiling down, leaving the floor cold.
WarmlyYours designed a high-output system using the Slab Heat Cables and Slab Heat Mats, spaced at a tight 3.0 inches apart to maximize heat delivery into the substantial concrete mass. By embedding the heating elements directly into the slab, the entire floor surface becomes a massive, low-temperature radiator, distributing consistent, comfortable, and highly energy efficient heating from the ground up. This method ensures the concrete floor is perpetually warm to the touch, making the large addition a cozy, usable space even during the cold Ontario winters.
The installation involved laying 3 units of 3' x 56' Slab Heating Mats and 1 unit of a 323 ft. Slab Heating Cable, totaling 627 sq. ft. of coverage area, all controlled by four SmartStat Programmable Thermostats. This high-level coverage guarantees the system can function as the primary heat source for the entire area, meeting the demanding heating requirement for the new construction.
Featured Products
To deliver high-performance, in-slab heating for this large new addition, the following WarmlyYours products were utilized:
- Slab Heat Cables & Mats (WSHC & WSHM Product Line): These robust, shielded heating cables are specifically designed for embedding directly into concrete slabs. They are built for durability and provide a reliable, high-output heat source ideal for primary heating in large spaces and over surfaces with high thermal mass like concrete.
- SmartStat Programmable Thermostat (TH115-AF-GA-08): Four of these advanced thermostats were specified to manage the large heating load. The SmartStat offers GFCI protection, a dual-sensing floor and air sensor, and an easy-to-use programmable schedule. This allows the homeowner to optimize the heating schedule to align with their lifestyle and take advantage of Ontario's off-peak electricity rates, further enhancing the system's efficiency.
