Natural gas heats up quickly and releases far more energy than coal or oil.
For one thing, natural gas is much more environmentally friendly than coal or oil, it produces up to 45% less carbon dioxide (a major greenhouse gas that is thought to affect global warming) than burning oil. Using oil for heating also produces significant amounts of sulfur, which you will have to pay a specialist to come and clean out. Natural gas is also the most cost-efficient option, as many other methods require complex equipment and lots of it. The convenience of central gas heating, with an exception for the few areas that do not have gas main connections, makes it the most popular tool for central heating.
