Question

Why do we need central heating system in houses?​

Answer 1

Human beings can manifestly live without central heating. I know you don't think you can, but you can. It is in your genes. Let us imagine you are now living in a very cold place, and you cannot buy heating fuel - or it isn't available, and you are facing a long, cold winter.

Answer 2

Oil based central heating systems have been used around the world for many decades. These heating systems function much the same way as the gas type heating system; an oil fueled boiler heating water to the correct temperature, then sends the heated water via radiators throughout the house.
