If you're thinking about getting a new boiler, it's important to know the different types and how they work.
The size, type and make of boiler can all affect how much energy you use and how your home and hot water is heated.
When it comes to what type of boiler, there are three main types to consider:
Gas Boilers (assuming they are a quality brand, installed correctly) are very reliable and theres not much that can go wrong.
However when they go wrong, parts can cost £££'s and waiting for parts can be days.
This is another reason why Installers will advise on Boilers being serviced annually and insome scenarios (care homes for example) bi-annualy.
Servicing must be carried out by a Gas Safe registered engineer, this allows them to ensure your Boiler is running safely and also gives them a chance to insoect the components and advise on wear and tear components which are starting to fail.
Replacing these parts before they decide to give up causes less disruption and means your not caught short.
There are various types of system avaiable, Below is a brief explanation of the most common types of Central Heating Boiler found in Domestic property's-
A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combination boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.
They are also very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump.
Compact sizes make combi boilers perfect for smaller properties
Ideal where there is little or no loft space
No need for a hot water cylinder allows increased living space
No cold water storage tank frees up a loft for conversion
No risk of loft pipework freezing
Less pipework in the home makes installation typically cheaper
System boilers require a cylinder for storing hot water, however the major heating and hot water system components are built into the boiler itself, making it quicker and easier to install. In addition, there is no need for a tank in the loft, so it can be an option in a home with little or no loft space or where the space is earmarked for a conversion.
These boilers are also compatible with solar water heating systems, which deliver environmental benefits as well as lower energy bills.
Regular boilers (sometimes known as traditional, conventional or heat only boilers) are ideally suited to homes that already have a traditional heating and hot water system which is linked to a separate hot water cylinder. These boilers also need a cold water storage tank in the loft to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.
A regular boiler may be the best option for replacing an existing boiler if the property has an older radiator system, as it might not be able to cope with the higher water pressure that is delivered by system or combi boilers.
