Efficiency of Space Heaters
When it comes to space heaters, efficiency is a crucial factor to consider. A heater’s energy efficiency is calculated by how much heat it produces per unit of energy (usually expressed in BTUs) and is known as the heater’s efficiency rating. A higher efficiency rating means that the heater can produce more heat using less energy. Inefficient heaters could end up costing more in electricity bills in the long run.
- One of the most efficient space heaters is the ceramic space heater. These heaters use ceramic plates to heat the air and have a fan that distributes the warm air throughout the room. Ceramic heaters are energy efficient because they can retain heat for a longer period, and only consume energy when the thermostat needs to be triggered to maintain a specific temperature.
- Infrared heaters are also a good choice when it comes to energy efficiency. These heaters work by emitting invisible radiant heat, which warms up the objects in the room, including furniture and people. Infrared heaters do not use air to transfer heat, which means there is no heat loss. They are also quick to heat up and do not require preheating like other types of heaters.
- Fan heaters and oil-filled heaters are less efficient than ceramic and infrared heaters. Fan heaters use electricity to heat up a metal coil and then blow the hot air into the room using a fan. However, these heaters tend to dry out the air and can cause respiratory problems with prolonged use. On the other hand, oil-filled heaters have large oil reservoirs that absorb heat from the heating element and transfer it to the air. These heaters are slow to heat up, but they are safer to use than other types of heaters because they do not have exposed heating elements.
Factors Affecting Efficiency
The efficiency of space heaters can be affected by various factors, including the size of the room, insulation levels, and outdoor temperature. A heater’s output should match the size of the room to ensure that it works efficiently. In an un-insulated room, heat easily escapes, and the heater will struggle to maintain a constant temperature. Similarly, in extremely cold weather, the heater will consume more energy to maintain a specific temperature.
Efficiency Comparison Table
| Heater Type | Efficiency Rating | Heat Output | Pros | Cons |
|---|---|---|---|---|
| Ceramic Heater | 95% | 5,000 – 7,000 BTUs | Energy efficient, quick to heat up, and safe to use | Costly when compared to Fan and Oil-Filled Heaters |
| Infrared Heater | 90% | 1,500 – 6,000 BTUs | Energy efficient, quick to heat up, and do not dry out the air, good for allergy/asthma sufferers, Safer than other Heater Types | Expensive than oil-filled and fan heaters |
| Fan Heater | 80% | 1,500 – 7,000 BTUs | Cheaper than Ceramic and Infrared Heater, Portable, Heats up quickly | Heated Air Dries out Air, Less safe when compared with Ceramic and Infrared Heater, Only heats nearby Objects and People |
| Oil-Filled Heater | 70% | 5,000 BTUs | Energy efficient, Silent when Operating, Safe to use, No Exposed Heating Elements | Slow to heat up, less power, costly in the long run than other Heater Types |
When choosing a space heater, it is essential to consider a unit’s efficiency, output, and safety features. Ceramic and infrared heaters are generally more efficient and safer than fan and oil-filled heaters, albeit at a higher price. However, various factors, such as insulation levels and room size, can affect a heater’s efficiency, so it’s essential to also factor these into your purchasing decision.
