A buyer's guide to gas boilers


As people become ever more "green" conscious, home owners look to their boilers as potential gas guzzlers in terms of energy, as well as a drain on the finances. Energy prices are at an all time high, and with gas boilers representing such a significant investment, it makes sense to know all you can when choosing a boiler.

Types of Gas Boilers

There are a number of gas boilers available in the market and they include:

- Combi boiler (also known as a "combination" boiler)
- Regular boiler (also known as a "traditional" or "conventional" boiler)
- System boiler

Combi boilers provide both heating and hot water directly from the boiler; whereas regular and system boilers heat your central heating system directly and produce hot water for your cylinder.

How to decide which type of boiler is most suitable to you

The following examples may help you choose which type of boiler is most suitable for your specific situation.

Combi boiler

- You looking to use your loft space as a room conversion or other functional purpose,
- You live in a maisonette, flat or bungalow, where you have very little or no roof space at all,
- You need to have hot water available as and when you require it without having to wait for the water to slowly heat up.

Regular or system boiler

- Your home features more than 2 bathrooms,
- Your water pressure is relatively low (e.g. your water flow seems weak; to confirm this check with a professional).

Regular, system or combi boiler

- You need to replace an old boiler in order to improve your central heating system and how it functions.

Factors to consider when buying a gas boiler

How environmental friendly is it?

The gas boilers of today are well known as being more environmentally friendly than ever given that they have to meet stringent government guidelines, this is none so surprising. That said however, they do vary from boiler to boiler, so be sure to ask or research each boiler's green credentials.

Taking care with installation

When having a gas boiler installed take care to choose a properly qualified professional with the correct certifications. Whilst you should ask them directly about their certification, you should also check directly with the relevantauthorities to ensure that they are truly a qualified professional.

Where you should buy your boiler from

Bearing the aforementioned point in mind (and never, ever attempting a gas boiler installation yourself) you are free to choose where you purchase from (e.g. you don't have to have an installation from where you purchase the boiler from). You should therefore undertake through research online as to what's on the market, what's suitable for your home and whether there are currently any deals or offers on.
