Combi boilers aka combination boilers, are very efficient condensing boilers
that don't take up much room. They are now increasing popular due to their compact size and highly efficiency.
C
ombi boiler's are a unique kind of boiler because there's no
need to store hot water - which means you don't need a hot water cylinder
within an airing cupboard.
Why choose a combi boiler
They have in-built protection from rapid changes of water temperature
while you are in the shower due to thermostat controls (most combi
boilers have these controls and they often come as standard too).
If you don’t have much roof space for the installation of a
different type of boiler, then a combi boiler is likely your best bet. Also, combi boilers are a very efficient boiler and they can heat water on demand.
Advantages of a combi boiler
The advantages of combi boilers are the monetary savings
seen on the cost of hot water, plus the fact that you get water out of the
taps or shower at the same pressure as if it was from the mains. Also because there are no tanks being placed in the roofing and so less pipe
work to install. This results in a faster installation which can reducing initial costs as well. Also because combi's are so popular, boiler service costs should be relatively low whilst parts and boiler engineers really easy to find.
There are a range of central heating boilers of all shapes and sizes, from small and compact boilers that can fit in the space of a small kitchen cupboard to larger, high-output monoliths.
Different types of central heating boilers available have their own benefits and drawbacks. Boilers can run on gas, oil and even electricity ? Plus they differ in size and output - so it can be hard to know what you need, and what you can really have!
What boiler do I need?
Depending on your property (inc. size and number of bedrooms), there are a range of types of central heating boilers to think about - which differ in size, cost and output too. Whatever your need it’s vital that you get good solid professional advice and boiler quotes before you proceed.
How about a Combination Boiler ?
The most popular boiler is the combination boiler (often referred to as a ‘combi’ boiler) and half of boilers sold within the UK are new combi boilers. This is mainly due to their convenience, as most central heating systems use a copper cylinder to provide hot water, but a combination boiler will heat the water needed around the house within its unit. A combi system will not require a cold water tank or separate water cylinder to supply it, so that the costs of hot water will be a little lower than with a boiler that holds water in a cylinder.
What about a Wall Mounted Boiler ?
Most boilers are designed to be wall mounted, with more compact and lighter design. Wall mounted boilers come in many versions, such as with a Fanned Flue or Room Sealed. Lik most new boilers, the wall mounted type of boiler needs to have a “system by-pass” fitted, which is used to filter water throughout the boiler appliance to prevent problems later on like “kettling”.
Maybe a Condensing Boiler ?
This type of boiler has a “heat exchanger”, which allows heat to be re-circulated making it more energy efficient. One of the issues with condensing boilers is the pluming effect it creates from the flue terminal, which is often mistaken for steam. The pluming is not a danger, although is considered a nuisance and will occur for all the time that the boiler is running. Because of this, the placement of a condensing boiler can be more difficult.
