Not if it was disconnected properly
if your heater just went out in your house and you need a really good electrical furnace you should really consider getting a whole new furnace from a hardware store or a heater store.

Good question.A furnace is a enclosure in which energy in non thermal form (e.g. a fuel) is converted into heat. The inside of the enclosure becomes an intensely hot place.A heater is an apparatus that heats or provides heat.In refineries, the terms "furnace" and "heater" are used interchangeably, sometimes with the word "fired" in front of heater.
Furnaces have no RPM ratings
A hybrid heater system combines the efficiency of a heat pump with the reliability of a traditional furnace. This results in lower energy costs, reduced environmental impact, and improved comfort and control over indoor temperatures.
A furnace water heater combo can save space, reduce energy costs, and provide efficient heating and hot water for your home.
The air heater in a boiler system preheats the combustion air before it enters the furnace, enhancing the efficiency of the combustion process. By raising the temperature of the incoming air, the air heater improves fuel combustion, leading to reduced fuel consumption and lower emissions. This increased efficiency helps the boiler operate more effectively, ultimately providing better energy output and overall system performance.
When choosing a sauna heater for your home sauna, consider the size of the sauna, the type of heater (electric, wood-burning, or infrared), the heating capacity, the materials used in construction, safety features, and energy efficiency.
Yes you can do that. I had an oil fired furnace that also heated the hot water in a coil inside the furnace. I got an electric hot water heater and had a plumber disconnect the coil in the furnace and hook up the electric hot water heater. No problems after four years.
