However, it is important to understand the laws of physics which remain unchanged in spite of what ads might claim.
Most people do not realise that direct acting heaters are, in fact, 100 percent efficient. These heaters include radiator heaters, infrared heaters and panel heaters. In any of these units, one kilowatt of electrical energy produces one kilowatt of heat.
Many manufacturers claim that infrared heaters produce the same amount of heat as a radiator but uses less electricity. It should be noted that there is no evidence to support this. In order to improve the energy efficiency of a direct acting electrical heater, the laws of physics would need to be rewritten. That would be a true miracle!
Heat Transfer Methods
When it comes to heat transfer methods for electrical heating, there are two methods- convection heating and radiation heating. Convection heating involves heat being circulated through the room via air circulation. Radiation heating, on the other hand, directly transfers heat energy to objects or people.
A heating expert, Tony, at Electric Heating Expert elucidates this for us, “Infrared heating panels produce radiant heat while electric radiators produce both radiation heat and convection heat. To help you better understand, the heat produced from electric radiators are similar to a boiler-fired wet radiator heating system.”
Some infrared heating manufacturers have claimed that their heaters can save up to 50 percent on your heating bills compared to other forms of electrical heat. They propose that radiators must use 2 kilowatts of electrical power to heat the same amount of space as an infrared heater that only uses 1 kilowatt of power. Although it may seem plausible to receive this 50 percent energy savings, physics states that 2 kilowatts of power will produce twice as much heat.
There are other flaws to infrared heating panels. First, these panels only heat using radiant heat. The infrared waves travel in a straight line and the heat is absorbed by objects and people. In order to feel the heat, you must be directly in front of or underneath the infrared panel and there cannot be any obstructions. Most homes will have cold spots when using infrared heaters. To counteract this effect, more heating panels will need to be installed, which can increase energy usage.
Most electric radiators have a thermostatic control that helps to regulate energy consumption. Infrared heat panels, on the other hand, continue to draw full wattage while the unit is running.
Once the room reaches the desired temperature, an electric radiator will only use energy intermittently and proportionally. The amount of electricity needed is related to the air temperature of a home. A well-insulated home that has little heat loss can lower the amount of energy needed by a radiator to maintain the set temperature by as much as 30 to 40 percent.
Infrared heaters continuously draw power. Radiation heat only heats up objects and air, not the air, which makes a temperature sensor or thermostat redundant. If an infrared panel is turned off, the heat dissipates and the room can quickly become cold.
Uses of Infrared Heating Panels vs Electric Radiators
Infrared heating panels can be hard to place in a home; however, there are certain applications where this type of heat is useful. For example, infrared heating panels are great in traditional churches with their large sizes, lack of insulation and vaulted ceiling. Most of the occupants at the church will be seated. If the infrared panels are suspended overhead, the radiant heat will beam downward and warm attendees.
Modern radiators are the best solution for most places, including homes and commercial properties. These systems are reliable, easy to install and control and keep the entire space warm. Radiators can heat large and small areas very effectively and inexpensively.
If you want a heating system that will keep you warm and comfortable at an affordable price, look no further than electric radiators.
