These establishments manufacture non-electric, non-warm-air heating equipment — including heating boilers, heating stoves, floor and wall furnaces, and baseboard or wall heating units — for residential and commercial end markets. Operations involve metal fabrication, welding, assembly, and quality testing of components that will be installed in occupied structures and connected to fuel or steam systems.
Questions to investigate
- What specific product types are manufactured — heating boilers, wall furnaces, baseboard units, heating stoves, or a combination?
- What fuel types do the products use — gas, oil, propane, solid fuel — and what are the operating pressure ranges?
- What quality control and product testing protocols are in place, and do products carry third-party certifications such as UL or CSA?
- What are the primary distribution channels — wholesale, OEM supply, retail — and does the insured distribute internationally?
