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.
Is a space heater more efficient on the 800W or 1500W setting?
Efficiency has nothing to do directly with the wattage selection. Efficiency would be calculated based on the amount of power used to deliver a specified amount of heat. In your case you have stated the power requirements by indicating 800 and 1500 watts are available. Assume the1500 W setting gets to your desired temperature in 5 minutes and then cuts off and the 800 W setting takes 9 minutes. If the heater delivered the exact amount of power of the setting then if it took 5 min at 1500 W. it should take (15/8) x 5 = 9.375 min at 800 W. If the 800 W setting got to the heat setting desired in anything under 9.375 min you could say the 800 W setting was "more efficient". Any anything over 9.375 "less efficient".
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.
What yields a higher heat output a electric heater with a higher or lower voltage?
Does not matter. But in a practical sense Its cheaper to get heat from high voltage because smaller wire, smaller breakers, and definitely less heat loss from the circuit wiring. It's called ixiR loss. Same reason overhead transmission lines are obcenely high voltage values. It is all relative. Heat equals this times that. Lower this, raise that. Horsepower equals this times that. Lower rpm, raise torque or vice versa. Navy wants planes to fly faster, lose weight, raise hydraulic pressure, reduce hydraulic line size. Electric, hydraulic, mechanical, it's all equal.
Is the heater gas or electric, and how does it affect the bill?
The heater is either gas or electric. Gas heaters typically cost less to operate than electric heaters, resulting in lower energy bills.
Can electric thermal storage heater consume less than its rated capacity?
Yes if it is run at a lower votage than it is designed for.

Why does electric bulb become dim when electric heater in parallel circuit is switched on?
The electric heater draws some of the electrical current in the circuit, which reduces the current available for the electric bulb. This leads to a decrease in the brightness of the bulb as it is receiving less power.
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.

What are the benefits of installing a high efficiency electric water heater in terms of energy savings and cost effectiveness?
Installing a high efficiency electric water heater can lead to significant energy savings and cost effectiveness. These water heaters use less energy to heat water, resulting in lower utility bills. Additionally, they often have longer lifespans and require less maintenance, reducing overall costs in the long run.
What are the benefits of using an electric inline water heater in a residential setting?
Electric inline water heaters offer several benefits in a residential setting. They provide instant hot water, are energy efficient, and take up less space compared to traditional water heaters. Additionally, they have a longer lifespan and can be easily installed closer to the point of use, reducing heat loss in the water distribution system.
What are the key differences between a hybrid water heater and an electric water heater, and which one is more energy-efficient and cost-effective in the long run?
A hybrid water heater combines heat pump technology with traditional electric heating elements, while an electric water heater solely relies on electric heating elements. Hybrid water heaters are generally more energy-efficient and cost-effective in the long run compared to electric water heaters, as they use less electricity to heat water.
Gas pool heater?
There are many gas pool heaters. Most are efficient and cost less to run than electric heating.
What are the differences between a tankless water heater and an electric water heater?
A tankless water heater heats water on demand, while an electric water heater stores and heats water in a tank. Tankless heaters are more energy-efficient and provide unlimited hot water, but may have higher upfront costs. Electric water heaters are cheaper upfront but have limited hot water capacity and may be less energy-efficient.
