The heat load for, say, an industrial production space is calculated by summing the heat loads of the electrical equipments installed. The environmental and HVAC engineering crew obtains the information directly from the equipment manufacturers. In the case of motors, pumps, ovens, dryers, etc., each manufacturer has the statistics available. They are usually not included with the equipment, but may be obtained from the folks who make the units when more precise and detailed workspaces are being considered or set up. It usually only takes a few phone calls or faxs to get the ball rolling.

it the level of heat....generated
Heat is generated by energy absorbed by element. Temperature co-effecient of the element and mount of electrical power excerted on the element determine heat energy output.
Heat generated by electrical resistance. Thermal mass of a metal plate.
Heat generated by overloading and improper current protection at the voltage supply source can cause electrical cords to ignite.
What is the heat generated by a typical fridge or freezer
Heat is generated in a working ballast because of the current flowing through it. Heat is bad for any electrical/electronic device and will eventually cause it to fail.
Good electrical conductors are useful because they allow electricity to be transmitted greater distances with less loss. This greater efficiency allows more of the electrical energy generated to be used, reducing the amount that must be generated. Good heat conductivity is less useful than good electrical conductivity, but it does make it easier to keep wires and cables cool, which further increases their electrical conductivity.
Heat generated in a nuclear fusion depends on the resistance of the plasma and the current.
If heat is generated during a chemical process, this indicates that it is an exothermic reaction.
Heat sink helps take out or dissipate the heat that gets generated from a device. If the heat that generated is not dissipated, it might burn out the device itself.
To calculate heat rate of a diesel generator set you need to divide the energy content of the fuel burned by the amount of electrical energy generated from it. The heat rate degrades over the years.
The energy in a star is generated by nuclear fusion.
That depends on the type of lighting . Fluorscent lighting for example , will give of little heat and fillament with generate far more .
The refrigeration equipment runs constantlty, heating the room. A fridge just removes heat from the inside area and pushes it out the rear coils. Any heat generated by the compressor is added to this.
It means that heat is being generated (created).
infrared ray from electromagnetic spectrum can creat heat directly ,heat is generated when photons are interact with matter. Due to vibration of molecules and electrons heat is generated.
Heat is heat. No matter how it is generated you will make steam. It will not effect you very differently because of a different heat source. A heated rock near a fire can exhibit a similar infrared light emission as electrical radiant heat does.
The root cause is usually based on the heat generated by poor or broken contacts in equipment or wiring. Certainly an electric arc will create a lot of heat, and it will cause insulation and anything else close to begin to burn. The cause may not disappear right away, too. An arcing wire can sustain a fire, even if it is extinguished. It can re-ignite at the next arc. We usually de-energize affected equipment or circuits ASAP after we extinguish the fire.
heat is in the electrical and this is useful
Fission of uranium nucleus with thermal neutrons release an enormous quantity of energy; this heat can be converted in electrical energy in a nuclear power reactor.
A battery consists of a group of 2 or more primary or secondary cells which convert chemical energy into electrical energy. One portion of the chemical energy is transformed into heat energy and the other portion into an electrical current.
electrical energy produces heat energy
The reactor core produces heat as a result of the nuclear fission chain reaction, and the heat is used to produce steam to drive a conventional steam turbine/generator.
The heat is generated by the body's metabolic processes, and the various reactions are regulated by the hypothalamus in the brain. Most of the heat is generated from the internal organs, about 16% by the brain itself.
electric generated heat is 70% more expensive than gas generated heat .
