Most people think that central heating is a modern invention. This could not be further from the truth. One of the earliest forms dates from 67 BC and comprises excess heat air from cooking stoves was piped to other portions of a dwelling. The Roman Empire employed the technique of central heating by conducting heat under floors and through pipes in order to heat individual rooms. In the 13th Century monks in Europe were using these same methods, which were referred to as hypocaust. Using water for central heating began to be used in Russia and Europe in the 1700s. By the 1830s steam heat was invented and the first radiator followed in the 1850s.

Today there are a variety of central heating systems in use. In Europe and the UK it is common to find the hot water for taps and appliances incorporated into the central heating system by use of a heat exchanger. In a sealed system, which is more common to the US, the hot water for taps and the water for heating purposes are located in separate systems of circulation.

Steam central heating is accomplished by heating the water in a boiler, followed by the hot steam being circulated to the radiator. The water is usually heated by gas, coal or oil. Under floor water heating works in a very similar fashion. The difference is that the heated water is circulated through pipes under the floor; warming the floor and the air above it. In these central heating hydronic steam or water systems the same water is used over and over. This technique is also employed under some public areas such as sidewalks or parking lots in order to melt ice and snow. Outdoor applications require a type of antifreeze to be added to the water.

Heat pumps are another form of central heating. Where winter temperatures are mild heat pumps extract the heat from the outside air. In colder zones geothermal pumps are used; they pull heat from the ground. The only problem with a heat pump is that in extremely cold conditions, some form of supplementary heat is required.

Typical gas or electric central heating units are similar to the way a stove works, either one heats burners with their respective fuels and then a forced air system of ductwork and a fan circulate the heat.

Today the concentration is on energy efficiency. In most areas heat pumps are considered to be the most energy efficient, even though they may require a backup heating source at certain times of the year. Gas is generally, named as the second most efficient. However, it depends on where you live, the type of home that you are heating and the energy costs in your area. In some cases, all electric heating systems may be the best choice.

Before deciding on a new heating system for your home, you should have an energy check up by a professional. They can explain how you can improve your energy efficiency and reduce the loss of heat from your home. No matter how efficient the central heating furnace, your home will ultimately decide how warm or cold it is indoors and how much it is going to cost to heat it.
