The Research Report on Application of Low-Carbon Technology at Home!

Low-CarbonA research on the application of low-carbon technology at homes almost covered on space heaters. As opposed to perceptions of many people, even a 100% energy efficient electric heater will not offer full efficiency as long as it is using a non-renewable electricity source. According to the report, this was pointed out factoring in the entire energy consumption of the power plant and the heater itself.

Even the geothermal electricity converts about 35% of its heat into electricity, and thus an electric heater that uses geothermal electricity will not offer 100% efficiency. In short, you can achieve full energy efficiency if the electricity source is renewable. The electrical heat is probably the most expensive and least efficient for space heating unless your electrical consumption rates are significantly subsidized.

The study found that all the energy efficient heater ratings do not ‘exist’ because the heater elements are converting electricity to heat energy. The fundamental concern starts from the energy conversion right at the source. If you are looking for the most energy-efficient electric heater, it is advisable to start seeking for one that is more ‘effective’ – not really efficient, according to the study results analysis.

How Electric heaters Work

Low-Carbon LivingAn electric heater passes current through a wire, which is electrically-resistant. Through this resistance, the electrical energy is converted into heat energy. And that is how they are said to be energy efficient. However, given that some models use fans to blow air around, the energy used for powering the fans is not actually converted into heat. According to the study, this is true unless all aspects of the law of entropy are factored in.

According to the study done for the space heaters for heating large rooms, there is more energy lost during the generation at the plant. For instance, a coal or fossil fuel powered plant, about 55% of energy is lost during the production of electricity. During the electricity transmission, a maximum of 6% of energy is also lost. Therefore, a 100% electric heater will be at most 45% efficient. The exception of the issue of 100% efficiency for electric heaters is the heat pump. Heat pumps usually provide more heat than the resistant-based electric heater, and that is why many people say they are 100% efficient.

Types of Electric Heaters

Since you have an overview of how electric heaters operate, now I will outline the types of electric heaters. So, you can continue reading so that you can understand about each of them.

Central electric heaters

These involve either the use of air-electric furnaces with room vents and ductworks or air-electric boilers with radiators installed in every room. For the air electric furnace heating system, air is heated by a heating element, then compelled through a furnace by a fan, and then pumped through various ducts that are installed throughout a house. On the other hand, forced-air boiler heating system involves heating water by a heating element, and then the hot water starts circulating with the help of an electric pump or on its own.

Baseboard electric heaters

These ones spread heat by both convection and conduction. Convection occurs when heated air expands, becomes light, rises, and draws some colder air in from underneath. The air currents draw the heat into and around the house. Conduction occurs when heat is transferred from a heating element to the surrounding air in the house.

Movable energy saving space heater

Low-Carbon Technology at HomeThese can operate by radiation or convection. The most common types are the movable convection heaters and movable radiative heaters. The radiative heaters use a very hot heating element that is enclosed in a bulb-like glass tube. A reflective metal strip at the back of the tube directs the radiative energy to the surrounding space. The convection heaters are like baseboard convection heaters, though a fan may be used to propel heated air in a specific direction in order to be distributed throughout a room.

In conclusion, the study provides broad information about resistant-based electric heaters. Typically, the resistant-based electric heaters are energy efficient electric heaters. However, different heaters distribute heat energy in different ways that can be less or more effective for the intended job. According to the research, it will be more appropriate to talk about energy effectiveness with which the heaters satisfy your heating needs rather than speaking of efficiency!
