HOW DOES CENTRAL HEATING WORK?
The hot water systems that keep your home warm and comfortable
WORDS AILSA HARVEY
As the winter months descend in temperate climates, returning home to a place of warmth and relaxation can become crucial. Heat doesn’t come freely, however, and its production relies on the use of either gas, electricity or renewables such as solar energy. You can think of a home’s central heating system almost like the circulatory system in your body, which regulates your temperature. In this comparison, the activity of your home’s boiler is a bit like the chemical reactions that take place in your organs, producing heat. In a standard gas boiler, a controlled furnace is produced to heat the water that flows into it. This water is the ‘blood’ of the home, ready to be pumped through the walls and floors into the radiators of each room.
