Types of Boiler ExplainedPosted on 4th July 2017
There are many different types of boiler on the market. This can be confusing, especially as government legislation states that all new gas-central heating boilers must be what is known as a ‘condensing’ boiler. In this week's blog, we give an overview of the main types of boiler that you will encounter.
Q. What is a ‘condensing boiler’?
A. This isn't strictly a model of boiler but it is a feature of boilers that makes them particularly efficient. The legislation around condensing boilers has been put in place due to their energy efficiency, as condensing boilers use over 90% of the heat from the fuel they burn.
Q. What is a ‘conventional boiler’?
A. Conventional boilers (also known as open vent or regular boilers) operate with both a cylinder and a tank, which means they can take up a lot of space. A downside of these boilers is that they can lose heat easily if the tank is not well insulated and once the hot water runs out you will need to wait a while for it to reheat.
Q. What is a ‘system boiler’?
A. System boilers (also known as a sealed system) have no water tank but they do utilise a water cylinder which will usually be fitted in an airing cupboard. With this system, the water is not heated on demand and you will have to wait for it to heat up if the hot water runs out.
Q. What is a ‘combi boiler’?
A. Combi or combination boilers are so called as they combine both water heating and central heating as one unit. One of the most popular boiler choices in the UK, this type of boiler heats water directly from the mains, so you won’t need a water storage tank taking up space in your loft. Because they heat water on demand and only heat what you need, this makes them very cost effective and reliable.
