What to Consider Before Installing a New Boiler

A boiler can last for over ten years in your home, so choosing one that doesn’t suit your needs will haunt you well into the future. We’ve outlined several questions that you should be asking yourself before you think about installing a new boiler...

What type of boiler do I need?

All modern boilers are condensing, but it's important to think about which type of boiler you should install in your home. There are several options at your disposal, but here are the three most common types of boiler...


Combi boilers are great for smaller homes as they require no components other than the boiler itself. They heat water at mains pressure as and when it is needed; making them great for the environment. A downside of combi boilers is that they struggle to keep with a high demand for hot water, so maybe aren't suited to homes with multiple bathrooms.


System boilers require a water storage cylinder and the boiler unit itself. They can meet a high demand for hot water so are great for larger families or homes, while not taking up too much space. However, you need to wait for the hot water to be heated and energy may be lost through the cylinder.


Conventional boilers require two water tanks, a boiler and a water storage cylinder; meaning they require the most space out of the three. They can meet a high demand for water, making them suitable for homes that have space for the components. Similar to system boilers, energy can be lost through the cylinder.

What size boiler do I need?

The size of your boiler depends on which type you choose and how much demand you have for hot water. Choosing a boiler that is too large can cost you excess money to run over the years, wasting a considerable amount of money. Choosing a boiler that is too small means it will struggle to meet your demand for hot water. This decision sounds very tricky, but our gas engineers in Swindon can easily assist when given information about your home.

Where will my boiler go?

A lot of boilers are positioned in kitchen cupboards, keeping them out of sight and out of mind. While this suits most homes, those with smaller kitchens may struggle with this, so consider alternative locations. Airing or storage cupboards are also ideal.

Which boiler manufacturer should I choose? 

From Worcester Bosch, to Vaillant & Viessmann to Glow-worm and Baxi, there are lots of different manufacturers to choose from. Each manufacturer has its benefits, from extended warranties to great customers service to low running/installations costs; you need to consider which is most important!
