Is it cheaper to turn electric heat off and on to heat a house or just keep it at a low temperature?

The question asked is based on an urban legend, back from when cars used carburetors (e.g., before 1996). In the olden days, cars would use more gas upon start up due to carburetor usage. Because carburetors are now largely defunct, turning on and off your car (or computer, or house heating) will not cause more oil/gas consumption than leaving it running. Therefore, it is best for your wallet and the environment to turn off things you aren't using.

What does the trapping of heat energy by the earth's atmosphere maintain?
Its called the greenhouse effect!Surface temperature.
What is the relationship between heat and water?
The process of changing one form of energy into another form of energy is called work (symbol: W). For example, when an electric motor changes electric energy into kinetic energy, it is doing work.Heat (symbol: Q) describes energy in transit (i.e. the flow of energy) from a warmer body to a cooler body.So, for example, when an electric kettle is switched on, electrical energy is converted into the internal energy of the water (and of the kettle itself) -in other words, work(W) is being done to the kettle. As the internal energy* of the water and the kettle increases, its temperature rises above the abient (surrounding) temperature, so energy is then lost from the kettle to its surroundings by heat(Q) transfer. So, the change in the water/kettle's internal energy is the difference between the work done on the kettle, and the heat transfer away from the kettle. To summarise:change in internal energy = W - QSo, we can say that a change in internal energy is the difference between work and heat. And this is the relationship between work and heat.(*'Internal energy' is the sum total of the various energies associated with the vibration of the molecules of any body. All bodies have internal energy. Lower internal energy is associated with lower temperatures, and higher internal energy is associated with higher temperatures.)
What are the similarities between light and heat energy?
They are both forms of energy They have wave length and frequency.
Which warms up slower and holds it heat longer water or land?
Given equal volumes and equal temperature changes without any change of state, no substance requires as much heat for a given temperature increase or expels as much heat during the equivalent temperature decrease than water.
How electric geyser works?
A electric Geyser has a Element screwed in the side of the inner water container, with the heated side submerged in water, parallel to the element (sometimes center) is a thermostat unit to control the temperature by switching the element off once the desired temperature has been reached. The element itself is made with nichrome wire, which is a resistive wire, When a Electric current is passed through the nichrome wire the resistance of the wire restricts the current causing a pressure of electrons and protons (as water builds pressure in a hose pipe when the end is restricted) and intern creates heat as a byproduct.
What is difference between auxiliary heat and emergency heat?
None. There is no difference. Auxiliary heat and Emergency heat are synonymous. It is the electric heat strips that kick on whenever the outside temperature drops too low (below 30 degrees or thereabouts) for the heat pump to efficiently heat the house. The electric strips are a little more expensive to run, but they will heat the house.
Is electric fireplace cheaper on electric than central heat?
any type of electric used for heat is expensive. but heating the home is cheaper in the long run because it use's 220 volts of electric heat. were as a fireplace would use 115 volts. which draws more amps then running on 220 volts
Whats cheaper electric or oil hot water?
As of 2014, electric is much cheaper than oil to heat a home. The oil costs has went up considerable in the last few years.
Why not just use that energy consumed running the heat pump to run electric heaters inside the house and heat it directly that way?
Heat pump is more efficient. If you use electric heaters, 1 joule of electric energy will produce 1 joule of heat energy. If you use heat pumps, 1 joule of electric energy can pump several joules - perhaps up to 5 or 6, depending on the outside temperature, and the efficiency of the heat pump - of heat, from the outside to the inside.
What do you set your heat at?
The temperature you want your house to be.
Will an electric fireplace reduce oil costs?
A 1500 watt Electric fireplace will heat 400 square feet to a comfortable temperature within 30 minutes. Thus you won't have to turn on the house heat or be able to keep it at a lower setting. A Electric Fireplace cost about $30 a month to run 5-6 hours a day.
What is auxiliary heat?
Usually a backup heating unit. For instance in a heat pump when the temperature drops below the temperature where the heat pump cannot extract heat from the existing air electric heating elements kick in.
Are gas cooktops cheaper than electric cooktops?
The difference between gas cooktops and electric cooktops it the type of energy used to produce the heat used to cook the food. The electric cooktop needs electricity while the gas cooktop uses natural gas or propane.
Which is better Electric heat or heat pump?
Heat pump - lots more efficient and dramatically cheaper to operate. Heat pump is definitely better as it not only saves electricity bills but is also easy to maintain and install.
What are three types of energy used to heat the house?
electric, fossil fuels and geothermal
Do the electric furnaces operate the same as a gas furnace?
The simple answer is yes it produces heat and is distributed to the rooms in your house; unless however, you are using electric baseboard heat which works on convection, or electric radiant heating panels.
What should temperature be for heat?
the temperature mat should be around 76 c unless if it is new to the house, that temperature should be 76c.
