Frequently Asked Questions
Can radiant heating be the primary heat source in Ontario?
Yes, radiant floor heating can serve as the primary heat source in Ontario homes, provided the system is designed to meet the full heat loss calculated per CSA F280-12. In well-insulated new construction, radiant-only systems are practical. In older or less-insulated homes, a supplemental heat source may be needed.
What heat sources work with hydronic radiant systems?
We design for condensing gas boilers, cold-climate air-to-water heat pumps, ground-source heat pumps, and solar thermal with backup boilers. The best choice depends on your fuel costs, project budget, and OBC compliance path.
Do you design radiant systems for renovations, not just new builds?
Yes. We design for both new construction slab-on-grade and above-floor systems (thin-slab, staple-up, or aluminum plate track systems) suitable for renovation projects.
Can radiant heat be combined with a forced air system?
Yes. Many Ontario homes use radiant heat as the primary heating system paired with a ventilation-only forced air system for HRV distribution and cooling. We can design both systems in a coordinated package.
