Buying Guide
How to Buy a Space Heater
This short guide helps you pick the right electric space heater quickly. It covers what matters most, the main heater types, the specs to check, where to buy and practical tips so you can act with confidence.
1. Key factors to consider
Match heater size to room size and use. A 1500 W unit is common and ideal for small to medium rooms; some tower models claim coverage up to 100 270 sq ft for larger living areas. Prioritize safety for bedrooms and homes with kids or pets. Look for tip-over protection, overheat/thermal cut-off and cool-touch surfaces. Consider noise if you need quiet overnight operation; some models run as low as about 32 dB. Think about energy controls like a programmable timer, an ECO mode and a reliable thermostat so the heater cycles instead of running full-power non-stop.
2. Main heater types and when to choose them
- Oil-filled radiator - Best for gentle, long-lasting background heat. Very quiet and allergy friendly since there is no fan. Great for bedrooms, basements and places where you want steady warmth.
- Ceramic tower / PTC heater - Heats up quickly, often includes oscillation to spread heat and precise digital thermostats. Good for quickly warming large or frequently used rooms and for directional heat.
- Convector panel - Slim profile, fast convection heat and often offers wall-mount or freestanding installation. Good where floor space is tight or you want a discreet heater on a wall.
3. Important features and specifications to check
- Rated power - 1500 W is the common maximum for portable electric units in Canadian homes. Confirm your circuit capacity before use.
- Thermostat accuracy - Digital thermostats with 1°F increments give better comfort and energy savings than simple high/low switches.
- Energy functions - Look for ECO mode and programmable timers (12 or 24 hours) to reduce runtime and cost.
- Safety - Mandatory: tip-over switch, overheat cut-off, child lock, cool-touch housing, and certified markings (ETL, CSA or equivalent).
- Noise - If quiet is essential, look for models rated in the low 30s dB for sleep or office use.
- Portability and installation - Wheels, handles, or wall-mount kits matter. Check if the unit supports both floor and wall mounting if you need flexibility.
- Extras - Oscillation angle (for example 70 degrees), anti-freeze mode that kicks in below about 5°C, and a sealed oil reservoir for oil-filled models.
4. Where to buy, common mistakes and quick expert tips
- Where to buy - Shop online for the widest selection and price comparisons. Buy from reputable retailers or authorised sellers and check shipping, returns and warranty details. Try a local store if you want to test noise and controls in person before buying.
- Common mistakes to avoid - Do not use extension cords or power bars rated below the heater's amperage. Avoid units with exposed heating elements for indoor bedroom use. Do not buy only on price; skip models lacking basic safety features or certification.
- Expert tips - For constant background heat choose oil-filled types. For fast, directional warmth pick a ceramic/tower model with oscillation. Use the thermostat and ECO mode rather than running at max power. Place the heater on a flat, hard surface away from curtains and furniture. Keep an eye on cord length and choose a model with a built-in handle or wheels if you move it frequently.
Final Thoughts
Choose a heater that fits the room size and how you will use it. Prioritize certified safety features, a programmable thermostat and an ECO mode for efficiency. If you need quick heat choose a ceramic tower, for silent steady warmth choose an oil-filled unit and for space-saving options consider a wall-mountable convector. Buy from a trusted seller and test noise and controls where possible before finalising your purchase.
