Top Things to Consider When Purchasing a New Boiler

Your boiler is one of the most robust appliances in your home as it usually stays strong for around 10 to 15 years. However, nothing lasts forever and your boiler will need to be replaced at some point, so it’s important to do your research when looking for a replacement.

Here are some of the top consideration to think about.

Which type of boiler should you buy?

Combi boilers

In the UK, combi boilers are one of the most popular choices and account for over half of all domestic installations. They heat water directly from the mains so they are not only energy-efficient but affordable to run. Additionally, these boilers do not require a bulky storage tank so the installation is quick and you’ll be provided with good water pressure.

Gas boilers

A gas boiler burns natural gas to generate heat for the central heating and domestic hot water. Natural gas is cleaner than oil to burn, produces less soot, and the way it is obtained is better for the environment. Plus, since natural gas is gathered from pipes that run deep underground, no oil wells or drills are required.

LPG boilers

LPG stands for Liquid Petroleum Gas. These types of boiler need a supply of stored gas to generate heat so they’re ideal for properties that do not have direct access to the main gas grid. LPG boilers can be supplied by a central or individual bulk storage tank which holds a typical capacity of between 1,000 and 2,000 litres which can be easily replaced when needed.

Oil boilers

Gas boilers and oil boilers work in a similar way but the fuel is stored differently. Whereas gas boilers enjoy a constant supply from the National Grid oil boilers need a tank of oil that is kept somewhere on the property.


Purchasing a cheap boiler comes with a high risk of problems occurring later down the line. You should always consider if you’re getting value for money. Your boiler should be an investment, not a quick fix!
