What to Consider When Choosing the Best Space Heater for Bedroom Warmth
Before purchasing a space heater for a bedroom, keep in mind some important considerations. Give each point some thought to help choose the best space heater for bedroom warmth in your home.
Several types of space heaters are on the market, each of which produces heat differently.
- Fan heaters have electric coils that produce heat and spinning fan blades that push warm air into the room. Position these electric heaters on a desk or dresser and aim them toward the bed while you sleep.
- Convection heaters produce heat with electric coils, ceramic plates, or oil-filled fins. As the heat rises, it pushes cold air down toward the heater. The heater then warms the cold air, which rises and pushes colder air back down.
- Infrared heaters warm objects in front of the heater, not the air around it. Infrared heaters are excellent for producing localized heat, but some models struggle to produce a uniform amount of heat. Moreover, the bright glow of the coils can affect light sleepers.
- Micathermic heaters use electric coils to warm a sheet of mica sandwiched between them. They produce both convection and radiant heat.
Safety is the most important consideration when using a space heater. For example, a heater placed too close to a curtain, bedspread, or other combustible object could cause a fire. It’s critical to keep space heaters away from objects. Aso ensure that smoke and carbon monoxide detectors are working.
To help mitigate danger, many manufacturers install safety features on their space heaters, the most important of which may be the tip-over switch, which shuts off the unit if it falls over. Also, space heaters that use combustible fuels sometimes feature low-oxygen cutoffs that disable the unit when enough oxygen isn’t available for safe combustion. Prior to using any type of space heater, read and understand the manufacturer’s instructions.
Nearly all heaters complete some type of convection cycle, which means they can heat most rooms if sized correctly. Luckily, most bedrooms are relatively small compared to wide-open great rooms or the primary living space, which means nearly any space heater will do.
Space heaters come in either watt ratings (labeled “W”) or British thermal units (described as BTUs). Almost all electric space heaters are rated for either 750 or 1,500 watts; the smaller size is suitable for small rooms, and the larger size for larger spaces. As to BTUs, a heater that produces 9,000 BTUs is typically plenty for even a large bedroom.
Whether the heater uses electricity, a fossil fuel, or some other type of fuel source, energy efficiency should be a factor when choosing the best space heater for bedrooms. While heating an entire home with space heaters would not be an efficient use of energy, using one to heat a bedroom while the rest of the house stays at a lower temperature can actually save money.
In homes without heating zones, the temperature throughout the entire home might need to be quite high to make the bedroom comfortable overnight. With a space heater, the rest of the home’s heating system can hover at energy-efficient temperatures while the bedroom stays toasty warm.
Any extra noise in the bedroom can affect a light sleeper’s rest. On a space heater, typical fan levels measure about 35 to 45 decibels, equivalent to a quiet background conversation. Oil-filled heaters usually make bubbling sounds that are clearly audible within the room.
Product labels don’t often list noise level, so if absolute silence is necessary, a micathermic heater might be the way to go. This type of heater doesn’t use a fan or oil, so the heat is produced quietly and comfortably.
