The right way to heat a detached garage or workshop in Metro Vancouver depends on insulation, how often you use the space, and whether gas or electrical service already runs to the building.

Quick answer: For most Metro Vancouver homeowners, a ductless mini-split heat pump is the best all-around option for a detached garage or workshop, since it heats and cools efficiently without ductwork. If the space isn't insulated or you only need occasional heat, an electric unit heater is a cheaper starting point, and a gas unit heater makes sense if you already have a gas line and want lower-cost heat for heavy daily use.

Before picking any heating equipment, look at the building envelope. A detached garage or workshop is often uninsulated, has a single-pane window or two, and a door that doesn't seal well. Any heater you install has to fight those losses every time it runs, so insulating the walls, ceiling, and especially the garage door (with rigid foam or an insulated door panel kit) will cut your heating cost more than upgrading the heater itself. Sealing air gaps around the door frame and any wall penetrations also makes a noticeable difference in a Metro Vancouver winter, where damp cold and wind are more of an issue than deep freezes.
Once the space is reasonably sealed, the heating choice becomes much simpler and the equipment can be sized smaller, which saves on both installation and operating cost.

📞 (604) 359-1081Request a free quoteElectrical capacity is usually the limiting factor. A ductless heat pump or an electric unit heater both need a dedicated circuit, and if your detached garage is only fed by a single 15 or 20-amp circuit shared with lighting and outlets, you'll likely need an electrician to run additional capacity from the main panel first. If you're considering gas, confirm whether a line can reasonably be run from the house or meter to the garage, since trenching and permitting add to the cost.
For occasional-use spaces, an electric option is often the more practical choice simply because it avoids gas permitting and line extension costs. For a workshop you're in most days, a ductless heat pump usually pays for itself over time through lower operating costs and the added benefit of summer cooling.
A ductless heat pump installation for a detached garage or workshop typically falls in the $6,000-$18,000+ range depending on unit size, electrical work needed, and installation complexity. FortisBC and CleanBC rebate programs periodically offer incentives for heat pump installations, and the Canada Greener Homes Loan program is still active for eligible upgrades — but program details and amounts change, so check current eligibility directly with FortisBC or CleanBC rather than assuming a specific dollar figure applies to a detached structure. Electric unit heaters and gas unit heaters vary too much by size and installation complexity for us to quote a number without seeing the space.

⚠️ Safety note: If you're considering gas heat for a detached structure, running a new gas line and installing a gas-fired unit heater requires a Technical Safety BC permit and must be done by a licensed gas fitter — never attempt this yourself or use an unlicensed installer.
