Central heating ensures that your entire house is warm, and not just the room that you're in, so that you can feel free to move around your home without fear of the biting cold. Central heating is the even distribution of heat throughout your home from a central heat source. Warm water distributes heat evenly to every room in your house through the use of a network of pipes. Even if you live in an area where the temperature is moderately warm, your home can become very cold in the winter months because of insufficient insulating and ineffective heating systems.
