When utilized in a small space, convection heaters were energy efficient. When used to heat extensive areas or even a whole home, they are not exceptionally energy efficient. Convection heaters are perhaps the most energy-efficient alternative for providing heat in some situations. However, there will be times when they are not ideal for reducing winter energy expenditures. Please continue reading to learn how convection heaters work and how to get the most out of yours.
How does a convection heater heat a room?
Behind what most would think a simple heater is a lot of science. “To comprehend convective heat, you must first understand the three main methods of heat transfer: Conduct, radiation, and convection,” explains Chuck Schwartz, Ferguson’s HVAC Director for Training and Technical Support. “When one thing comes into contact with another, this is known as conduction. When someone grabbed the hot handle of the pot, almost everyone has experienced conduction.” This is in contrast to radiation, which “travels via wave without any intermediary like the pot handle,” he explains. So, would this reaction operate in terms of heating a room?
“First, it uses electricity to heat an essential element inside the unit, then it uses a fan or natural ascending warm air to transfer the hot air, ensuring that the warm air is dispersed uniformly around the room,” explains Light.
Is it expensive to run a convection heater?
While the cost of heating the apartment and home in the winter might be inconvenient, convection heaters are relatively inexpensive and can help you save money on your heating bill. A typical convection heater consumes 1500 watts of power per hour. Local electricity rates determine the cost of using the heater. According to national norms, a convection heater might cost roughly $0.20 per hour,” Light explains. He also says that, compared to conventional heaters, this could save a great deal of money because you’ll just be heating one room rather than your entire house.
Convection and radiant heaters
The distinction between the two types of heaters was based on heat transfer; one requires a medium for heat to pass, while the other does not,” Schwartz explains. “A convection heater generates heat by allowing air to circulate through it. It will ascend as it warms and migrates from hot to cold on the molecules in air or water. The air passing through a convection heater is either natural or pushed through the use of a fan. Typically, the term “convection heater” connotes “natural convection of air flowing without the use of a fan.
A radiant heater does not require air to flow from across the surface; instead, it moves by radiating heat waves until it is absorbed by something (like you). But, of course, heaters are more than that; there are other types of subcategories within radiant & convection heaters. The Light also dissolved these distinctions.
Precautions to take while using convection heaters
- Install smoke and fire alarms in places where convection heaters would be utilized. Look for heaters with an auto shut sensor that activates when the device becomes too hot.
- Never leave a heater unattended or even in a room with just an unattended child.
- Keep items like curtains & furniture at least three times away from the heater since a system malfunction and short-circuiting can cause a fire.
- Keep flammable items such as flammable liquids, rugs, and plastics as far away from the space heater.
It’s also worth noting that certain older homes and apartment complexes may be unprepared to handle these heaters, as they have the potential to trip electrical breakers. Before using a new convection heater, reading the safety handbook is usually good.
Is it true that convection heaters make a lot of noise?
Convection heaters with built-in fans are generally louder than heaters without fans. And, in most cases, the greater the heater’s temperature setting, the noisier it will get. The altering current passing thru the electrical transformer’s bands, which have an iron core, produces a faint “humming” noise in non-fan types. The system’s expansion and contraction produce a faint buzzing sound, which may be firmer on less costly heater types.
A convection heater is indeed the most excellent option in this situation. When you only need to warm up a room for a short or long time, convection heaters are the way to go. The heater would naturally circulate air throughout the room, and its thermostat and timer will allow you to manage the temperature (most come with these options). This will save you money and keep the room from overheating.
What should you consider before buying a convection heater?
Before choosing a convection heater for your home, there are two crucial considerations. Let’s have a look at what they have to offer.
1. The Amount of Heat You’ll Require
Assess your home’s heating requirements before investing in a new convection heater. This will assist you in determining what is ideal for your individual living needs. Most space heaters have a rating that indicates the size or approximate square footage of the space they are best suited for.
If your heater is just too tiny for the warming room, it’ll have to work extra hard merely to keep the room warm, resulting in more energy consumption and a more excellent electric bill. A decent general rule is that in every single centimeter of floor space, you’ll need roughly 10 watts.
2. Energy Costs You Might Face
Take a look at your most recent power bill and note the money you pay in electricity per “kilowatt-hour” to get an idea of how much your convection heater would cost to run. The cost will differ depending on the state and location. Next, calculate the number of hours the heater uses per day and convert that to kilowatts per hour. For example, if your pay $0.15 per kilowatt for electricity and your heater has a wattage of 1,500, using the device for 24 hours will cost you $5.40.
How much electricity are convector heaters using?
Convection heaters often have a 2000W power output, which does make running them extra expensive. Additionally, you could tend to run convection warmer for more extended amounts of time (compared to radiant heaters).
Hopefully, this article has given you a better understanding of convection heaters and their operation. Convection heaters are a terrific option for tiny heating spaces or just a few rooms in a house. On the other hand, central heating systems are more energy-efficient for large rooms or entire homes.
