Buying Guide
FAQs
What does ‘low wattage’ mean for a space heater, and why is it important?
Low wattage typically refers to heaters under 750 watts, compared to the standard 1500 watts. This is important because they consume less electricity, which can lower your energy bills and reduce the risk of overloading a circuit, especially in older homes or offices.
Will a low-wattage heater be powerful enough to warm my room?
These heaters are best for personal spaces or small, well-insulated areas like a desk cubicle, a small bedroom, or a bathroom. They are designed to provide direct, personal warmth rather than heating an entire large room.
What is the difference between a ceramic and an infrared low-wattage heater?
Ceramic heaters use a fan to blow air over a hot ceramic plate, warming the surrounding air. Infrared heaters emit radiant heat that warms objects and people directly, similar to the sun, making them feel warmer instantly but without heating the air.
What key safety features should I look for in a low-wattage heater?
Prioritize heaters with tip-over protection, which automatically shuts the unit off if it falls. Overheat protection is also crucial, as it turns the heater off if its internal components get too hot.
Are low-wattage heaters more energy-efficient and will they save me money?
Yes, they are more energy-efficient simply because they use less electricity to run. Your savings will be significant if you use it to warm only your personal space instead of turning up the thermostat for the whole house.
What are the main benefits of a low-wattage model over a standard 1500W heater?
The primary benefits are lower energy consumption and a reduced risk of tripping a circuit breaker. They are also typically smaller and more portable, making them ideal for use under a desk or in tight spaces.
Do I need to sacrifice features like a thermostat or timer with a low-wattage model?
Not necessarily. Many modern low-wattage heaters include useful features like an adjustable thermostat for maintaining a set temperature and a programmable timer for automatic shut-off, adding convenience and control.
