Buying Guide
FAQs
What is the most important factor when choosing a heater for a large room?
The most critical factor is the heater’s wattage and heating capacity, typically measured in British Thermal Units (BTUs) or the recommended square footage. For a large room, you should generally look for a heater with at least 1,500 watts. Always check the manufacturer’s specifications to ensure it is rated for the size of your room to ensure effective heating.
What’s the difference between a ceramic, infrared, and oil-filled radiator heater?
Ceramic heaters use a ceramic element to heat the air and are great for quick, focused warmth in a room. Infrared heaters warm objects and people directly, similar to the sun, and are very efficient for spot heating without drying the air. Oil-filled radiators use a heating element to warm oil inside the unit, which then provides a steady, long-lasting, and quiet heat.
Are there key safety features I should look for?
Yes, safety is paramount for any space heater. Look for models with an automatic tip-over switch that shuts the heater off if it’s knocked over and overheat protection that turns it off if it gets too hot. Additionally, a heater with a cool-touch exterior and a sturdy, non-tip base is essential, especially in homes with children or pets.
How much will it cost to run a large room space heater?
The operating cost depends on the heater’s wattage, your local electricity rate, and how long you run it. A standard 1,500-watt heater will use about 1.5 kilowatt-hours (kWh) of electricity per hour. To estimate your cost, multiply your utility’s rate per kWh by 1.5 to find the hourly cost of running the heater on its highest setting.
What does ‘Eco Mode’ or an energy-saving setting do?
An ‘Eco Mode’ or energy-saving setting helps reduce energy consumption and lower your heating bills. This mode typically allows the heater to cycle on and off or automatically adjust its wattage to maintain a set temperature. By using less power continuously, it provides more efficient and cost-effective comfort over time.
How important is noise level for a large room heater?
Noise level is a key consideration, especially if you plan to use the heater in a bedroom or a living room while watching TV. Fan-forced heaters, like ceramic models, will produce some noise from the fan. In contrast, infrared and oil-filled radiators operate almost silently, making them ideal for noise-sensitive environments.
What features add the most value to a space heater?
Beyond basic heating, features that add significant value include a programmable thermostat, a remote control, and a timer. A 24-hour programmable timer allows you to schedule the heater to run only when needed, improving energy efficiency. A digital thermostat provides more precise temperature control, leading to greater comfort and potentially lower energy costs.
Is it safe to leave a space heater on overnight or unattended?
While modern heaters have many safety features, it is generally not recommended to leave any space heater running while you are sleeping or away from home. The risk of fire, although low with certified models, is never zero. For overnight use, ensure it has all the key safety features like tip-over and overheat protection, and place it on a stable, clear surface away from flammable materials.
