Throughout Europe, boilers are the most popular appliance for providing central heating and hot water in the home.
Depending on what fuel is available in the home, boilers can run on natural gas, liquid gas, oil or electricity.
Boilers can be wall hung or floor standing. Wall hung boilers are more popular because they take up less space than floor standing boilers. However, traditionally, floor standing boilers have a higher output and are especially suitable for larger properties.
Types of boiler:
Open vent boilers - Sometimes known as heat only boilers, provide central heating and hot water using a boiler, a hot water storage cylinder housed in an airing cupboard and water tanks in the loft.
Combination boilers - Combination boilers or combis, provide central heating and instant hot water so they do not need a separate water storage cylinder.
System boilers - System boilers are often referred to as sealed system boilers. They provide central heating and hot water via a storage cylinder housed in an airing cupboard. However, there is no need for water tanks in the loft, as with an open vent boiler.
Some boilers have an integral hot water storage tank. These combination-store, or combi store, boilers are usually floor standing.
Boilers can be either conventional or condensing.
The term condensing, or high efficiency, means the boiler recovers more heat from the amount of oil or gas that is burnt, making it more efficient than conventional boilers. By recovering and using heat that would otherwise be lost up the flue, the best condensing boilers are more than 90% efficient. Although condensing boilers cost more initially, they are very economical to use, and can pay back the initial extra cost in fuel savings. Condensing boilers also have lower emissions of toxic gasses making them much better for the environment. - Description added by: Baxi + Add your own description
Buildings are where the majority people in modern societies spend most of their time, whether in homes, commercial buildings, industrial facilities or retail complexes. The design and construction of buildings require a large investment of time, money and other resources. Then they require additional resources for running costs and maintenance. Bad design can greatly increase energy consumption over the whole lifetime of the building. Fortunately, good building design can greatly reduce energy consumption during construction and ongoing throughout a building's life. - Description added by: David Lockie + Add your own description
