How Space Heaters Are Made To Help You Challenge Winter’s Chill

Nov 6, 2025
Now that November’s colder temperatures have arrived, Canadians are looking for ways to keep warm. This is an every-year occurrence, of course. Naturally, the use of long coats, scarves, toques and gloves generally come into play. But what about keeping warm while indoors? Sure, many people will turn up the temperatures of their homes. However, many others will choose to reduce their overall energy costs by making use of space heaters.
Let’s walk through the manufacturing process of a typical electric space heater, shall we?
Design and material selection.
Manufacturers begin by specifying the wattage output, size, type of fuel, safety features and target environment. For electric heaters, key components include a heating element. They are often made from nickel-chromium alloy wire or PTC ceramic. As well, insulation materials such as mica, ceramic or magnesium oxide must be considered.
The outer casing materials are often made from sheet steel, aluminium or heat-resistant plastic. Materials are also needed for control circuitry. The core heating element is usually made from materials like nickel-chromium or iron-chromium-aluminium alloys.
Component fabrication.
The heating element wire is wound into a coil or spring shape to maximize surface area and heat transfer. The outer tube or casing is then formed. Steel strips are welded or rolled into tubes, or stamped into housings. Pipe making is mainly done by machines to form steel strips into metal outer tubes.
For tubular heaters, after coil winding, the inside of the tube is filled with magnesium oxide powder. This is for insulation and heat conduction. Magnesium oxide powder is an important component because it provides both electrical insulation and thermal conductivity.
Assembly.
The wound coil and terminals are welded into place. The assembly is filled, rolled or mechanically treated to compact insulation, then formed to correct dimensions. Additional components are fitted, including thermostats, tip-over switches (for portable heaters), casings, control panels and safety cut-offs. For more complex industrial units, additional control systems, ventilation fans, mounting hardware and sensors may be included.
Testing and quality control.
Each unit must pass electrical safety tests for grounding resistance and leakage current. Heating performance tests are also needed to assess temperature output and distribution. Durability tests are done via cycling the heater on and off for extended periods. Materials and workmanship are inspected, including tube geometry, insulation density and weld integrity.
The diameter of tubing must conform to regulations and end cuts must not have any burrs. Compliance with safety certifications for both Canadian and North American markets is verified. Electric heaters must have overheat protection mechanisms, as well as proper grounding and insulation.
Packaging and distribution.
Finished heaters are labelled with heating capacity, voltage, wiring instructions and safety warnings. For facility or heavy-duty models, crates or pallets may be used. For consumer models, retail packaging, user manuals and warranty cards are included. Logistics teams coordinate seasonal demand, ensuring heaters reach distributors and customers before the cold truly sets in.
