How To Pick the Most Efficient Space Heaters
If you are considering a space heater for your home or office you want to be able to get the most efficient and effective heater for your needs. To make sure that you buy the right device take the time to make a list of what size room you want to heat, the square footage in that room, and whether the heater will be the only heat or used as a supplemental heat source.
Then read the heater descriptions and use the following guide to help you pick through the features and descriptions. Check the heater features against your needs, and make a pros and cons list to consider.
When a heater has a programmable thermostat, you decide exactly how warm or cool the room stays. You can set the thermostat a little lower and cause the heater to not run as long. These heaters will automatically shut down when the temperature in the room meets the thermostat setting.
When a heater has more than one heat setting it will produce a multiple of watts. The lower settings produce fewer watts and it cost less to operate the heater on lower settings. Get a device that has at least two settings, but three is optimal.
The oil-filled space heaters are more efficient at heating larger rooms. If you need to heat a small space then the infrared heaters are more energy efficient. You have to judge the heater you choose by the way you will be using the device and determine what variety of heating appliance will do the job you need to be done.
The Heating Elements in the Devices
Different heater types use different heating elements.
Ceramic heaters have elements that work very quickly to warm the room. They are small and can easily be moved to another room if you need to.
Infrared heaters are not as durable as ceramic heaters and will only give you service for about 5,000 to 7,000 hours. The heat they create warms the objects around them and those heated objects increase the temperature in the room.
These units distribute the heat more evenly and even when the unit is switched off the device keeps radiating heat.
Safety Tips for low-cost energy-efficient heaters
Safety is the primary concern with any heating appliance. You want to make certain that the device you have is not going to pose a threat to your home or family. The latest technology is improving the safety of all heating units, but there are certain things you can do to make sure that your heater does not cause a fire or a severe contact burn.
Energy Efficient Infrared Heater vs Oil Filled Heater
Infrared heaters are designed to heat more quickly than the standard oil-filled unit. Oil heaters are designed to heat rooms more evenly and can usually be used as the primary source of heat in a room due to their strength.
Infrared Heating Appliances
- These appliances are made to heat quickly and they are very efficient at heating small areas in a short amount of time.
- Compared to most other electrical heat sources the infrared devices are 40% more energy efficient. The big problem is they are simply not designed to heat larger rooms or areas.
- These devices are more portable than the oil-filled styles because the oil-filled units are larger and heavier
- No maintenance is required to keep the heater functioning
- They come in a wider variety of styles, shapes and colors
- They are easy to store in the summer months
Oil Filled Appliances
- Oil-filled heaters are capable of providing a more even distribution of heat than the infrared units do. This makes it possible for an oil-filled device to heat a larger area and maintain that heat.
- Oil-filled units do not have to run as long as some other heaters so they are efficient at using their electric, but infrared devices actually make better use of their fuel consumption.
- These appliances may cost more than the infrared style
- They cannot be used outside because the wind will move the warmed air away from where you want it
- These devices are safe to touch when they are in operation so they are safer in homes with children or pets
Frequently Asked Questions
1. Do oil-filled heaters use a lot of electricity?
An oil-filled is more energy-efficient than many other electric heater styles because they do not have to run as long to produce the same amount of heat. These devices usually have two or three settings and if they are operated on the low or medium settings, they will consume less electricity than when they are operated on high.
2. Is micathermic efficient?
Mica thermic, or mica panel heaters are the most efficient electric heaters available today. 100% of the electricity they take in is converted into heat for your space.
3. How efficient is an electric heater?
These heaters are very efficient at converting the electricity they require for fuel into heat. The amount of heat these units produce will be determined by the style of heater, size of the heater, and age of heater.
If you want a space heater that you do not have to sit right beside to feel the heat then we suggest you check out the Lasko 5790 Oscillating Ceramic Tower Heater. The oscillating fan will blow the heat farther into the room.
