Fundamentally, boilers are a furnace that are built in an accessible spot in a house and are fuelled by gas. They heat water, that they next pump to numerous outlets around the property whether they be showers, taps or radiators (boilers which supply both radiators and taps are classified as combination boilers).
Boilers are the most important part of any central heating system. If there was no boiler - no warm would be created. Most central heating boilers are attached to a mains gas supply, which means that there is a continuous availability of gas to burn. If you want to heat your house, the boiler is switched on - typically with an electrical switch - which usually opens a valve that enables the fuel (gas) to get in a chamber in which it's captivated. This ignited fuel then heats pipes running through boilers containing water, warming it during the process.
These pipes running thru central heating boilers are all part of a constant cycle of pipe work which is fitted through the building and it is linked to every radiator within the system. An electrical pump motor fitted within the heater pushes the heater water produced by boilers throughout the system which warms the radiators which heat the rooms in which they are fixed. By the time this water returns to the boiler it has cooled noticeably, so it's heated once again and the entire process begins once again.
Radiators are effectively made up of copper pipe that is coiled together so there is much more area meaning the area where the radiator is fitted will get heated quicker. Standard radiators fed from boilers may either be switched on or off and maintain a constant temperature, thermostatic radiators have particular heating controls on them and boilers function when required to keep them at the desired temperature. Thermostatic heaters let you control the temperature closely and just warm the parts of the property you desire meaning that they will save you money.
Basic central heating boilers are manually managed and are basically turned on and off when needed. Nowadays though in advanced houses, boilers are controlled by electronic programmers which permit you place the heating system to come on / off when required, these electronic timers allow consumer to heat their house only if needed - you certainly don't need to heat a property while no-one is in.
Boilers come in three main types - open vent, mixture and system - all of these work on the basic principles explained above. The main differences come once the boilers are used to warm water for taps - many of them use tanks to store warm water (system and open vented), and others produce hot water when needed direct from the mains supply (combination).
When looking at boilers and deciding which will match your property best it will always be good to contact a trustworthy dealer of boilers who will be capable of giving you expert advice and information. Only attempt to set up a central heating system inside your residence if you're a properly trained skilled with all the relevant safety qualifications.
