Buying Guide
FAQs
What is the most energy-efficient type of space heater?
All electric space heaters are 100% efficient at converting electricity to heat, but the best type for saving energy depends on your use case. For heating an entire room, an infrared heater is often best as it warms objects directly. For personal, close-range heating, a low-wattage ceramic or oil-filled radiator is more economical.
How can I tell if a space heater will be expensive to run?
Check the heater’s wattage, as this directly determines its power consumption. A lower wattage heater (e.g., 400-600 watts) will cost significantly less to run than a standard 1500-watt model, even if it runs for the same amount of time. Look for features like programmable timers and eco-modes to further reduce energy usage.
What safety features are essential for a low-energy heater?
Even low-wattage heaters can be a fire hazard, so safety is crucial. Look for overheat protection, which automatically shuts the unit off if it gets too hot. A tip-over switch is also vital, as it will turn the heater off if it’s accidentally knocked over.
What’s the difference between a ceramic heater and an oil-filled radiator?
Ceramic heaters use a fan to blow warm air into a space, providing quick, localized heat. Oil-filled radiators, on the other hand, silently warm the oil inside, which then radiates heat over a longer period, making them better for maintaining a consistent temperature in a small room. Radiators are generally quieter but slower to heat up.
Is an infrared heater a good choice for energy savings?
Yes, infrared heaters can be very efficient because they heat objects and people directly, rather than the air. This means you feel warm almost instantly without needing to heat the entire room, allowing you to keep the thermostat lower. They are ideal for spot heating in drafty areas or for personal use.
Are low-energy space heaters powerful enough to warm a room?
They are best suited for small spaces like a home office, bedroom, or for personal use at a desk. They are not designed to replace a central heating system or warm a large, open-plan living room. For supplementing heat in a small area, they are very effective and economical.
What features provide the best value for the money?
A programmable thermostat offers great value by allowing you to set a desired temperature and maintain it without wasting energy. An adjustable thermostat and multiple heat settings let you use only the amount of power needed. A simple timer is also a valuable feature for automatically turning the heater off when you leave the room or go to sleep.
