all objects emit electromagnetic radiation through empty space, as well as matter. So feel the heat from the electric heater due to radiation.
by radiation
Efficient, yes. But a poor choice for a heater. It's just a marketing gimmick. Every electric heater is nearly 100 percent efficient. Efficiency is a term not understood by many. Energy efficiency - useful work per quantity of energy. In other words, What is the job of an electric heater? To make heat. How much of the electricity fed to the heater is turned into heat? All of it. That makes it 100 percent efficient. In contrast an incandescent light bulb is only about 5 percent efficient, only 5% of the electricity fed to it is converted to light the other 95% is converted to heat.
Ceramic heaters are considered more efficient than electric conventional heaters, as they heat faster, are more stable when achieving the desired temperature, safer and if used in the lower power settings consume less energy
The purpose of a heater is to heat up the room when it is cold; by using gas
depends upon the square footage of the house or what devices will be operated from the house, if it is 1000 sq. ft. or lessand will havemostly gas appliances and gas heat a 100 amp but anything above that much sq. footage with a heat pump and electric stove/oven/ water heater and I would put in a 200 amp.
A fan.
by fire . an electric heater is a metal, and a metal is a good conductor of heat. so it can produce heat
The heat is being transferred by convection.
No, that is just for cooling. The heat from inside is transferred to the outside unit and removed by the fan.
With no water no heat can be transferred through the heater coils.
In a gas water heater: The gas flame warms the water, exactly the same way as a gas stove burner does for a pan of water on the stove. In an electric water heater, an element - same as an electric range element, but a different shape - heats up from electrical current, and transfers that heat to the water.
It's done with an electrical element inside the tank.It's the same principle as boiling water in an electric jug.Hope this helps.
heat is transfered through space by radiation.
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
An electric room heater may be used to heat a room when it is cold, they are commonly used in the winter. An electric room heater may also be used to discharge the heat outside and keep the house cool.
Frozen Mammoths.
I think So
In effect it does. Electricity applied to the heater produces heat. Heat applied to the thermocouple produces electricity.
