Heating

There are many types of heating systems. Often, central heating in cold climates to heat private houses and public buildings. This system consists of a boiler, furnace or heat pump water, steam or air in the middle, such as boiler rooms, mechanical rooms or the house is a large building. Water is known as hydraulic cooling fluid. The system consists of pipes and forced air heated fluid and radiators heat the air. Long radiator in this context is misleading, since most of the heat exchanger to exchange heat, not radiation. Heater can be mounted on walls or floors, underfloor heating.

All but the simplest boiler and radiant heating water circulation pump, and ensure equal treatment of all refrigerators. Hot water from the other (secondary) hot water heat exchanger.

Forced air system sends warm air upward. In hot weather, you can use the same air tube. Forced air filter or air purifier.

Heat, electric heating, resistance, leading to passage of the electric wire is heated. It is used for floor heating, radiators, portable, backup, or as an additional heat pump (heating or vice versa).

Heating elements (radiators or open) must be placed in the coolest rooms in most windows to reduce convection currents caused by the passage of air and air space under the window to get a cold glass of liquid negative results. Machine away from the window directly into the hole to prevent "wasted" heat defeat the proposed measure. Cold air can contribute significantly to the subjective feeling of cold and mean discharge of air from outside is important for the heating system project.

Establishment of district heating is often credited to the ancient Romans, known as conductors installed in walls and floors of public baths and private villas hypocausts.
