The Smart Guide to Choosing a Space Heater
When cold weather sets in, a reliable heating solution becomes essential—whether you’re working in a workshop, garage, warehouse, or on a construction site. And as energy prices continue to put pressure on household budgets, many people are looking for affordable ways to stay warm.
That’s where electric heaters—often called portable heaters or space heaters—remain a popular, practical option. They’re easy to use, quick to set up, and many modern models are designed with efficiency and safety in mind. But with so many options available, how do you choose the right one?
Let’s break it down.
How to Choose a Heater
1) Set Your Budget First
Before comparing models, decide how much you’re willing to spend. On our website, you can filter heaters by price and quickly compare features to find the best option within your budget.
A good rule of thumb: more powerful heaters and models with advanced features (thermostats, timers, multiple modes) usually cost more upfront, but they can offer better comfort and convenience in the long run.
2) Match the Heater to Your Room Size
The size of the room you want to heat is one of the most important factors. Consider:
-
Room size and ceiling height
-
Heater wattage
-
Insulation and drafts
-
Other heat-producing appliances already in the room
-
Where the nearest outlet is (and how far the heater will sit from it)
-
Whether you have enough space to place it safely
A compact heater may be perfect for a small bedroom or office, while a larger space such as a workshop or warehouse typically needs a higher-wattage unit to warm up effectively.
3) Think About Portability
If you plan to move your heater from room to room, portability matters.
Look for:
-
Lightweight designs
-
Built-in handles
-
A compact shape for storage (EHG 5)
-
Wheels (especially helpful for larger, heavier heaters) - IDHG 40, IDHG 20, DHG 30
For big rooms, a larger heater with wheels can provide strong heating without being difficult to reposition.
4) Prioritize Safety Features
Heaters are built to generate heat—but they should also protect you, your home, and your workspace.
Modern heaters commonly include key safety features such as:
-
Overheat protection: turns the heater off if it gets too hot
-
Tip-over switch: shuts the heater down if it’s knocked over (especially important for homes with kids or pets)
These features are now considered essential for safe everyday use, and they add peace of mind in busy environments.
How to Use a Space Heater Safely
Even with built-in safety features, proper use is critical. Follow these essential guidelines to reduce fire risk and ensure safe operation:
Safe Placement Rules
-
Place the heater on a hard, flat, nonflammable surface.
-
Keep it at least 3 feet (about 1 meter) away from combustible materials such as:
-
furniture
-
curtains
-
bedding
-
paper or cardboard
-
-
Maintain a 3-foot kid- and pet-free zone around the heater.
Avoid High-Risk Locations
-
Don’t use a heater in a workshop or garage near:
-
paint
-
gas cans
-
matches
-
solvents or other flammable chemicals
-
-
Don’t use a space heater outdoors or on a patio where it can be exposed to wind, moisture, or debris.
Smart Usage Habits
-
Turn the heater off when you leave the room.
-
Turn it off before going to sleep.
-
Unplug the heater when it’s not in use by pulling the plug straight from the outlet (not the cord).
Cord and Outlet Safety
-
Never place a rug, carpet, or furniture over the cord (it can overheat or become damaged).
-
Check the cord periodically—don’t use the heater if the cord is frayed or worn.
-
Don’t plug another high-power device into the same outlet as the heater.
-
Avoid extension cords whenever possible, as they can overheat.
Bathrooms: If you’re using a heater in a bathroom, choose a model designed for bathroom use and equipped with additional electrical protection.
When It’s Time to Replace Your Heater
If your space heater is an older model, it may lack modern safety standards and efficiency improvements. If you notice unusual smells, overheating, unreliable switches, or worn cords, it’s often safer (and more cost-effective) to upgrade to a newer heater.
