Electric costs about 50% more than natural gas.

a woodstove. they are really effective. i have one and it is so warm. you even save money using it instead of your furnace.
Garn WHS with radiant floor heating. simple, effective, economical.
the most effective way to do so is to reduce the flow of the heat exchanger
If the wood stove is in the basement it will heat up the rest of the house but if it is not in the basement you have to find some way to vent it down there.

The most efficient way to heat a house using electricity is by using a heat pump system. Heat pumps transfer heat from the outside air or ground into the house, providing efficient heating without relying solely on electricity for generating heat. This method is more energy-efficient than traditional electric resistance heating methods.
The average baseboard heaters are designed to help heat your home in the most efficient way possible. Starting at the bottom of the house. This is the best way to make your house warm.
It is not always the case that cooling is more expensive than heating. It depends on the type of system you have and your utility rates. It also varies based on your location. You can find out the most cost effective way to heat and/or cool your home with an advanced load calculation. Then you can decide what type of equipment to use.
Heat pump. (electricity)
Oil is the most expensive way to heat anything. Check your cost per kwh on your electric bill- easy way= forget all the blah blah and divide the total $ by the total kw. The most efficient heat source is a heat pump. For $400 worth of heat with electric or gas equipment, the same heat may cost you as little as $100.

By Air
Increasing the temperature of the heat source is the most effective way to improve the efficiency of a heat engine.
I assume you want a way that would actually be a legitimate way of connecting a hard drive, as opposed to unnecessary silliness. SCSI controllers can be fairly expensive, most over $100.
Geothermal heat pumps use the Earth's constant temperature underground to heat a house. Heat from the Earth is extracted through a series of pipes buried underground with a fluid that absorbs the heat. This heat is then transferred to the house via a heat exchanger, providing a sustainable and efficient way to heat a building.
The easiest way would be to use solar heat from large windows or solar panels.
