	Central heating - Wikipedia, the free encyclopedia
		Central heating is a common method of providing warmth to the whole interior of a building, or portion of a building, from one point to multiple rooms.
		The most common heat source is through combustion of fossil fuel in a furnace or boiler.
		In this case, the heated water in a sealed system is allowed to flow through a heat exchanger in a hot water tank or hot water cylinder where water from the normal water supply is heated by it before being fed to hot water outlets in the house.

	Romans in Britain - Central Heating - Hypocaust
		To most people, their knowledge of the Romans was that they 'invented central heating.' Not the type we know today, but a form of underfloor heating that also warmed the walls.
		The danger from such a method of heating was not only from the materials in their homes, but also from the smoke that could become trapped and suffocate the dwellers through smoke inhalation.
		The furnace was the heating source of the system and this was placed on the outside of the house, below the floor that ran under the room that was to be the hottest room in the house.

	ACM: Central Heating
		Central Heating systems are typically a complete mixture of different metal types, including copper, aluminium, mild steel, brass and cast iron.
		Customers who develop corrosion inhibitors for central heating systems are best served with an instrument such as the single channel Gill AC or the multiple channel Gill 12 fitted with the AC and DC Weld Test Option.
		An important consideration, as in some areas of the central heating system, for instance in the middle of a mild steel radiator connected by plastic pipes, the steel is likely to corrode as if it isolated but still in contact with ions emitted by the other corroding elements.

	central heating
		Central heating has its origins in the hypocaust heating system introduced by the Romans nearly 2,000 years ago.
		From the 18th century, steam central heating, usually by pipe, was available in the West and installed in individual houses on an ad hoc basis.
		Central heating systems are usually switched on and off by a time switch.

	CENTRAL HEATING
		The popular notion is that heat pumps are not economical for the climate we live in.
		Flame is established in the combustion chamber and the heat exchanger.
		A central unit heats water either with oil, gas or electric and circulates the water through piping to radiators, baseboard, convectors or duct coils.

	Seattle City Light Conservation \| Home Heating \| Central Heating
		A central heating system has three parts: 1) a device that creates heat (furnace, boiler, or heat pump), 2) a means of moving the heat from the source to all the rooms in the house and 3) something to control the whole system.
		The heat mover we call a distribution system, which is usually comprised of ducts through which warm air moves or pipes through which hot water moves.
		If your home has a heat pump the amount of heat it puts into the distribution system includes both the heat it pumps from outside your house to inside and the heat contained in the electricity used to run the heat pump.

	Central Heating Systems - bleeding the system and radiators (via CobWeb/3.1 planetlab2.cs.unc.edu) (Site not responding. Last check: 2007-10-03)
		When new water is added to a central heating system, a certain amount of air also enters the system.
		With the central heating switched on, feel the top and then the bottom of the radiator - if the top is noticeably cooler than the bottom, there is a good likelihood that there is air in the radiator.
		If the Central Heating system is a sealed system, check the pressure and, if necessary, top up to the pressure as required (often 1 bar but check the instructions).

		Upon inspection, any heating systems are found to contain corrosion and sludge even if no flow problems have yet shown themselves, and it is prudent to power flush a heating system immediately before fitting a new boiler to prevent possible future problems.
		PowerFlushing your central heating system will remove any internal corrosion or sludge but will not cure any inherent faults within your system, but will bring these to our attention so as they can be dealt with in due course.
		Central Heating Clean have been using the PowerFlush system for more than 3 years and in that time we have transformed over 50 systems.

	HomeTips Guide: Central Heating and Cooling Systems
		A central heating system has a primary heating appliance such as a furnace or boiler located in an out-of-the-way spot such as a basement or garage.
		Homes without central heating normally utilize electric baseboard heaters or, in some cases, in-the-wall or in-floor gas heaters or radiant heat.
		Radiant heat is a comfortable, even type of heat that is radiated into living spaces by hot water, steam, or electric elements.

	Central Heating on the Costa Blanca North
		When a Central Heating system is installed and is fired by large gas bottles or gas tank then a Heating "Memoria" must be submitted to the Ministry of Industry.
		A Heating Memoria is a detailed report of your individual heating system with radiator outputs & sitings sketched onto a plan of the property and also appliance outputs and consumption.
		A Heating Memoria must be presented in the Ministry of Industry for every central heating installation whether gas or oil fired.

		A central heating system is only as good as its controls, the better the controls, the less wear and tear on the boiler and system.
		All central heating systems should have a Room Thermostat fitted, this will shut the heating circuit off, allowing the boiler and system to rest once the air has reached the desired temperature.
		Inside the valve is a wax capsule which expands when heated and stops the flow of water to the radiator.

		The water in the central heating system is separate from the water from the hot taps.
		In some older central heating systems water is circulated through the radiators by gravity rather than by a pump.
		Water can be manually added to the central heating system as required via a filling loop which is connected to the mains water supply.

	Central Heating FAQ
		Q: I have been told that the case gasket has failed, and a spare cannot be obtained, and it is leaking fumes and carbon monoxide.
		A: With regards to kettling, banging or popping noises in the central heating boiler, this is usually caused by either lime scale and corrosion debris becoming baked onto the inside surfaces of the heat exchanger, leading to localised boiling (due to hot-spots).
		Provided that the heat exchanger is not too scaled up, or damaged, then by following the procedure below, may restore it back to normal, for a few years more.

	Central heating: Pump overruns
		My house has gas central heating, with a Myson Economist boiler in the kitchen, and a pump, timer, etc in the airing cupboard upstairs.
		Your heating system is not as you describe, first of all the stat on the boiler has no effect on the temperature of your hot water.
		Hence when the boiler overrun circuitry kicks in to cool down the water in the heat exchanger, there is no where for the water to flow, unless a bypass circuit has been fitted.
