Heating

What Heating does

Calefactio (legal entity Les Solutions Calefactio) is a privately held Canadian manufacturer of hydronic heating system components, headquartered in Blainville, Québec, and operating in both Canada and the United States. The company designs, produces, and sells a comprehensive portfolio of plumbing and hydronic components — including ASME-certified and non-coded expansion tanks (ASME-Expanflex line), Cal-X-Tract air and dirt separators, Calbalance hydraulic separators (including 4-in-1 units that combine water, air, dirt, and ferrous debris separation with coalescing media), Calman air separators, Calvent automatic air vents, the ΔP dielectric pump flange valve line, pressure relief, service, and drain valves, tankless water heater valve kits, CondenSAFE condensate neutralizers, glycol make-up packages (GMP), and NSF61-compliant flow regulators. As the original manufacturer of GMP systems, Calefactio's value proposition centers on corrosion prevention, circuit isolation, and water quality management in closed-loop hydronic systems used for space heating, radiant floors, snow melting, and domestic hot water.

The business model is straightforward industrial OEM hardware sales: products are priced via quote (no public list pricing), sold direct to mid-market accounts and through regional representatives/agents serving commercial and industrial buyers, with a 24-hour inquiry response commitment and supporting tools including an online product sizing/selection tool, downloadable CAD files, and an annual product catalog (2026 edition). Customer segments span Commercial (primary), Residential, and Industrial, with all three segments addressed by the same component platform differentiated by pressure ratings, ASME code compliance, lead-free certification, and form factor. The company holds ASME Section VIII, NSF61, and lead-free brass certifications, which function as regulatory gating requirements for many bid contexts.

Strategically, Calefactio has expanded its platform over ~10 years (founded ~2013–2016, celebrating 10 years in 2026) by broadening its component portfolio and launching the Calefactio Radiant sub-brand for hydronic radiant floor heating and snow melting applications. Sales operations extend across Canada and the United States through regional agents and a direct inquiry channel. The company remains privately held, has not disclosed outside funding, and operates with a sub-50 headcount from a single manufacturing location.

Core offering

Calefactio manufactures hydronic heating system components for commercial, residential, and industrial applications. Its portfolio includes ASME-certified expansion tanks, hydraulic separators (including proprietary 4-in-1 models), air and dirt separators, condensate neutralizers (CondenSAFE), glycol make-up packages (GMP), and a complete valve family (dielectric pump flange valves, tankless water heater valve kits, pressure relief, service, and drain valves). The company also operates the Calefactio Radiant sub-brand for hydronic radiant floor heating and snow melting systems.

Product overview

Calefactio (Les Solutions Calefactio) is a Quebec-based manufacturer specializing in plumbing and hydronic heating products. The company offers a comprehensive portfolio of components for commercial, residential, and industrial hydronic systems. The core product lines include: condensate neutralizers (CondenSAFE), glycol make-up packages (GMP), flow regulators, expansion tanks (both ASME-certified and non-coded), air/dirt/hydraulic separators (Cal-X-Tract, Calbalance, Calman, Calvent), and a full range of valves (ΔP dielectric pump flanges, tankless water heater kits, pressure relief, service, and drain valves). Products are complemented by a sizing tool and the Calefactio Radiant sub-brand for radiant floor heating and snow melting applications. The portfolio follows a platform architecture approach where hydraulic separators and expansion tanks serve as foundational components, with complementary valve and separator products designed for integration in hydronic heating, cooling, and snow melting systems.
