In the case of a gas boiler, the gas is burned on-site. Depending on the design of the gas boiler, around 60% to 85% of the heat from combustion is used for heating the room. So the fuel used is (room heat demand) ÷ (boiler efficiency).
In the case of an electric heater, the electricity is produced at a central generating plant. Some of these are powered by nuclear fuel, some by renewable resources such as hydro, wind or sun, but most of them burn fuel (gas, or oil, or coal) to create heat that is then turned into electricity. The laws of thermodynamics set a limit as to how efficient this conversion can be, and generally well under 50% of the heat from combustion can be turned into electricity. Also a substantial fraction of the power that is generated is lost in the process of transmission from the power plant to the home. Therefore the fuel used is (room heat demand) ÷ (conversion efficiency x transmission efficiency.)
Since the denominator in the second case is usually smaller than the first, the use of electricity for heating requires more fuel to be burned than local combustion.
Large institutions often have co-generation facilities, in which a boiler generates heat that is used to produce electricity. The waste heat from generating electricity is then used for space heating of the buildings. While this is an excellent solution as far as energy efficiency, it has high capital costs and usually can be made to work only in a limited area with a dense population of buildings that are under a common management.
What else can I help you with?
What energy does an electric heater fire converts to?
An electric fire converts electrical energy into electromagnetic energy. In the form of heat and light.
What energy transfers in an electric fire?
In an electric fire, electrical energy from the power source is transferred into thermal energy, which produces heat and light. This process occurs as the electric current passes through the heating elements in the fire, causing them to heat up and radiate heat and light into the surrounding area.
What are the energy transfer in an electric fire?
In an electric fire, energy is transferred from the electricity supply to the heating element through the flow of electrons. The heating element then converts this electrical energy into heat energy, which radiates out into the room to provide warmth.
Energy Efficient Electric Heaters?
When it comes to heaters, electric versions have not had the best reputations in the past. They have been known for sucking electric and being major fire hazards. Thankfully, for the most part, those days are over. The newer versions of electric heaters that have been put on the market are a very energy efficient way to heat your home or office. Furthermore, thanks to quality standards that have been majorly changed in recent years, electric heaters are no longer as risky to use indoors as long as you follow safe using guidelines.
What is difference between vertical and horizantal boiler?
there are two types of boilers water tube and fire tube. fire tube boilers are divided in to two categories vertical and horizontal. this according to the construction of fire tubes. it is said that vertical boilers are inefficient than horizontal boilers. The vertical boiler is small capacity, and horizontal boiler is higher capacity, well, the horizontal boiler have many types according the drums, there are single drums boiler, and double drums boiler, while, the single drums boiler have fire tube boiler and water and fire tube boiler, double drums boiler is usually water tube boiler.
What energy conversion is in an electric fire?
In an electric fire, electrical energy is converted into thermal energy. The electricity flowing through the heating element causes it to heat up, emitting heat and radiating warmth into the surrounding area.
Which is better fire tube boiler or water tube boiler?
The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
What energy change takes place in a electric fire?
In an electric fire, electrical energy is converted into heat energy. The electricity passes through a resistor which generates heat through resistance, thus producing warmth and light in the process.
An electric fire has what kind of energy?
adictonal pull that forms the electric fire then when you let the arrow go it zooms fast but is all depends on the kind of energy you use and how much push you put in it. so you are looking for how much energyv is done by electric fire0
Where is the energy that enters an electric fire transferred to?
The energy input into an electric fire is primarily transferred to heat, warming up the surrounding air and objects in the room. Some energy is also lost through other means such as conduction, convection, and radiation.
What is a back boiler?
A back boiler is a heating unit installed behind a fireplace that heats water for central heating or domestic hot water, often using the heat from a fire or gas. It is commonly used in older homes as a space-saving and efficient heating solution.
I have heard that a gas stove is not as energy efficient as an electric one, is this true?
Gas stoves are dangerous and get really hot. Really in my opinion they are a fire hazard and are not safe but at the same time they are really great and simply uses gas.
