Buying Guide
What you should look for in a space heater?
Room size
Space heaters are available in a wide range of heating technologies, which produce heat and provide you with targeted warmth where you need it. To find your ideal space heater, consider the size of the room or area you wish to heat.
You can use the BTU (British Thermal Units) rating to calculate how many watts of heating power the heater can produce. For every square foot of space in a room, you’ll need around 10 watts of heating power. Suffice to say:
- For large rooms (400 sq. ft and above) – You’ll need a heater with a rating of at least 5,000
- For small rooms (150 – 200 sq. ft) – You’ll need a heater with a BTU rating of around 1,500
Safety features
We can’t stress enough how important this is. Space heaters that are equipped with cutting-edge safety features prevent the risk of fires and overheating.
So, look for heaters with safety features as follows:
- Overheat protection: Look for space heaters with sensors that detect overheating.
- Tip-over protection: Regardless of the heater type you choose, this is a crucial feature, especially if you have young children or pets at home.
- Cool-touch exteriors: Prevents the risk of burn-related injuries or accidents.
- Safety certifications and warranties: Ensure that the heater you wish to buy is certified by a Nationally Recognized Testing Laboratory (NTRL), such as CSA, ETL-Intertek, and UL, and that it has been tested to guarantee that it does not contain faulty or hazardous electrical components. As for warranties, space heaters often come with 1–5-year warranties. It is worth taking the time to study the user manual to learn about the space heater’s reliability and what is covered under warranty by the manufacturer.
Types of Heaters
To help you make the best choice, let’s go through some of the most common types of space heaters and what they’re best suited for below:
Convection heaters
These heaters work by heating the surrounding air, which then circulates throughout the room. They are typically designed for larger rooms and are often more energy-efficient and quiet than other types of heaters. Examples of convection heaters include baseboard heaters, wall heaters, and panel heaters.
Radiant heaters
Radiant heaters (not to be confused with radiator heaters) use an infrared bulb, coil or quartz tube to warm objects rather than heating the air in the room.
They are often used for spot heating in small rooms, and can provide instant heat. Examples of radiant heaters include infrared heaters and quartz heaters.
Fan-forced heaters
All fan-forced heaters use an internal blower fan, to force and circulate warmed air throughout a room. They are often used for small to medium-sized rooms, and can provide quick and efficient heating. Ceramic heaters and forced-air heaters are some examples.
Oil-filled heaters
An oil-filled heater is ideal if you want to keep a room at a steady temperature. These heaters work by heating heavy metal fins filled with oil which is sealed inside the unit, which then radiates heat into the room, covering a larger surface area.
They are often used for larger rooms, and can provide long-lasting heat. They also include radiator heaters and column heaters. If you have children or pets, consider purchasing a shielded radiator.
Howver, there may be a few drawbacks – the oiled radiator may take longer to heat up and as a result, they aren’t effective at heating up a chilly room quickly.
Mica-thermic heaters
Mica-thermic heaters function similarly to oil-filled radiators, with the exception that they heat up thin sheets of mica rather than heavy metal fins filled with hot oil. The heater provides radiant heat in the form of electromagnetic rays. They can be more energy-efficient than other types of heaters.
These heaters typically have a slimmer and space-saving design which makes it ideal for small to medium-sized rooms. Some models can be wall-mounted. Examples of mica-thermic heaters include flat-panel heaters and tower heaters.
Safety Tips: How to Keep Your Space Heater Safe?
Though most modern space heaters have safety mechanisms that help prevent the appliance from catching fire, some precautions must still be taken when using them to keep yourself and your loved ones safe.
Here are some additional safety precautions:
1. Keep the heater on a level surface
Always place the heater on a level or flat surface, and at least 3 feet away from any flammable objects, such as curtains, bedding, papers, etc. Remember not to put anything on top of the heater as well.
2. Keep the heater away from water
If you need to put one in your bathroom, keep it away from the sink or bath tub, to prevent the risk of electric shock. And don’t touch the heater with your wet hands!
For more information on installing heaters safely in bathrooms, check out this How to Select a Bathroom Heater article.
3. Read the instructions and warning labels
To ensure safe usage, only operate the space heater as per the instruction and warning labels.
4. Use a grounded outlet
Always plug the heater into a grounded or wall outlet to reduce the risk of electric shock.
A grounded outlet is an electrical outlet that is designed to protect against electrical shock by providing a safe path for excess electrical current.
The grounding wire is connected to the earth, which provides a path for excess electrical current to flow into the ground if there is a short circuit or other electrical problem. This helps protect against electrical shock and can prevent damage to electrical appliances.
It’s also important to note that using an extension cord or power strip with a space heater is not recommended, as this can increase the risk of a fire. If you need to use an extension cord, be sure it is rated for the heater’s wattage and has a heavy-duty, three-pronged cord.
5. Unplug the heater when not in use
This is especially important when you leave the room. Always turn it off and never leave the heater unattended while it is running.
6. Keep children and pets away from the heater
To prevent accidental burns or other injuries, keep young children and animals supervised and away from the heater when it’s in use.
