What are the features of an efficient electric heater?

The main feature of an efficient electric heater is, that is used up to 30% less engery than a conventional electric heater. This reduces the cost of the heater.


What is least expensive to run a heater with 750 watts and 7.1 amps or 600 watts and 12.5 amps?

The heater with 750 watts and 7.1 amps is less expensive to run. This is because it has a lower amperage, meaning it requires less electric current to operate. The 600-watt heater with 12.5 amps requires a higher electric current, which could translate to higher electricity costs.


Why is it important that the resistance of an extension cord used to power an electric heater be kept low?

An electric heater is one of the high-power appliances in a house, commonly taking 1.5 to 3 kilowatts of power. The current is high, and therefore there is a drop in the voltage applied to the heater equal to the current multiplied by the resistance of the cord. There is probably little power wasted, because any heat from the cord goes to heat up the same room. But a voltage drop causes the heater to draw less current because its resistance is constant, and therefore less total power is provided to heat the room. If the heater is thermostatically controlled so that it is not working all the time, the difference is small because any reduction in the heater's power would cause the thermostat to keep it going for longer, to compensate.


Why it is impractical to connect an electric light bulb and an electric heater in series?

It would not work because when two things are in series the same current has to pass through both. Normally an electric light takes much less current than an electric heater and therefore the light has more resistance. Most of the voltage would appear across the light bulb, so you would have a slightly dimmed bulb and a heater giving out very little heat. It would work if both devices were identical. Electricity supplies use a constant voltage, e.g. 120 v or 240 v, and all applicances are connected in parallel across the supply.


Why are electric motors more efficient than combustion engines?

electric motors lose very little power from friction, they also make more torque at a lower rpm than gas engines, they also require little maintenance and pollute less.

Does electric cooktop use the same amount of power no matter how high and how low you turn the controller?

NO. The amount of electric energy consumed varies depending on how high or low the setting is. Low setting will use less electric than high setting just as a 100 watt bulb uses less electric than a 200 watt bulb.

Gas pool heater?

There are many gas pool heaters. Most are efficient and cost less to run than electric heating.


Have A Lower Electric Bill?

In today's economy, everyone is looking for tips to help save money. Using less energy in a home or office is one guaranteed way to have a lower electric bill, thereby saving money. Try setting the thermostat a few degrees lower during the day in the winter months. Then at night, lower the setting a few more degrees. This will significantly lower a utility bill. Additionally, if there are any gaps or cracks around exterior doors or windows, those openings should be filled with a caulk product to help prevent the escape of warm air inside the home. Keeping cold air out and warm air inside will help lower bills.


Which electric heater is the most efficient?

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 Ups and Downs of an Electric Wall Heater?

An electric wall heater is the perfect solution for houses in areas that have mild winters. The heater will provide heat for the rooms around it, and it should be installed on a wall that is central to the whole house. Electric wall heaters have some good features and some bad features. Targeted Heat Usually an electric wall heater is a panel that runs from just below the ceiling to just above the floor. It radiates heat to all of the air that directly surrounds it. If you need to heat a three bedroom house, an electric wall heater may not have the strength to reach every room. If your house or apartment is smaller, however, an electric wall heater may be just what you need to keep a couple of the bedrooms and the bathroom warm. Where you place the heater will have a definite impact on how well it heats your rooms. Uses Less Electricity than Central Heating Central heating is designed to heat your entire house. It uses the thermostat to determine when to turn off and on, and it pushes warm air into every room through a ducting system. An electric wall heater doesn’t attempt to warm the entire house. It only warms the air in a radius around the heater. Heating is more immediate with an electric wall heater, so you don’t have to wait hours for it to heat the room. Since you have tighter control over when an electric wall heater is off or on, the heater consumes less electricity and delivers targeted heat when you need it. Easy to Control An electric wall heater is a very straightforward device. When the house is cold, all you have to do is turn it on. The room will start to get warmer immediately. When a room is too warm, all you have to do is turn off the wall heater and the room will begin to cool immediately. The air around an electric wall heater is not pushed around the room, so it remains warmer than if it were blowing through a vent. Electric wall heaters become very hot when they are in use, so keep children a safe distance away from the heater.


How do electric cars save money?

They save money because the maintenance on electric vehicles is lower. Also the price of Kwh vs mpg is lower meaning you pay less to drive on electricity then you would to drive on gasoline.


What kind of fuel is required for tankless water heaters?

How do you save money with a gas water heater?

If you are asking how you can lower your gas bill with an existing gas water heater with a tank, there are two things that you can do that will save lots of money. One is to insulate the tank with standard closed bat insulation. Simply wrap the insulation around the tank to keep the heat from escaping through the metal skin. The other way is to turn the heater down so the water isn't kept as hot, but still plenty hot for regular usage. a 10° drop in temp will save a ton of money over a year. If there are long periods of time that you do not need hot water, you can also turn off the water heater until about 30 minutes before you need it. If you are asking how a gas water heater is less expensive to use that an electric heater, this depends on your location and the price of the utilities. However a well maintained gas heater is much more efficient at producing BTUs (british thermal units) than electricity. Given similar costs of gas and electricity the gas heater will cost much less than electric over time.
