an electric furnace runs off of 208/230 Volts while a typical gas furnace runs off of 120 also a gas furnace will have a valve for the gas relay where the gas enters the furnace.
Yes, An Electric Furnace is Cost effectivecomparison with gas and fuel.
A "gas furnace" is called a furnace, an "electric furnace" is called an Air Handler
Because it has to produce an electric ark to ignite the gas that heats the furnace.
Gas ovens do save more money than electric ovens. But the drawback to a gas oven versus electric is that you do not get even heat exchange with gas as you do with an electric oven.
Yes,It depends if it is gas fired or electric.
There are a variety of gas furnaces that can without much effort be converted from one type of gas to the other, Natural gas and propane gasses work at different pressures; one gas is denser than the other.Converting gas to an electric furnace, you would be gutting almost the entire furnace, and replacing the gas components with electric heating coils, diodes and relays. This will take a lot of man-hours, fabrication, engineering, and parts. while not imposable, the conversion would be very expensive.
A furnace can be heated by fossil fuels like coal, coke, or natural gas, which is chemical energy or it can be electric.
This is a tricky question. Some homes may not have a gas line. Some cities may not allow gas furnaces and thus only electric is possible. Check with a local heating specialist for information.
Electric base board heater and gas furnace.
An ignitor on a gas furnace is an electric spark. An electric current is sent along a conductor, when it reaches the end the electric energy jumps across a gap to another conductor. This jumping electricity (think of it as a really tiny lightning bolt) creates a spark hot enough to ignite fuel.
Not knowing what kind of furnace you have makes answering this difficult. What type of furnace do you have (gas,electric, oil) and how old is it?
