Whether you are a new homeowner or you are updating your current heating, selecting the correct unit for your needs is often an overwhelming task.

Choosing the right system will improve energy efficiency, reduce heating costs, and ensure a reliable supply of hot water, so it’s vital to get things right. Read on to understand the different types of boilers and some key considerations.


  • Combination: Combi units provide hot water and central heating directly from the component. They don’t require a cold-water storage tank or a hot water cylinder, making them great for smaller houses and compact spaces.
  • System: Only works alongside a hot water cylinder, as they are designed to provide a continuous supply of hot water. This is why they are ideal for larger properties that have higher demands.
  • Conventional: As they need a cold-water storage tank and a hot cylinder, these are recommended for longstanding buildings that have traditional heating systems and old radiators. They work with existing pipework but require more space due to their additional necessities.


  • Electric: These boilers use electricity to heat water and are very easy to install due to their minimum requirements. They are great for homes where a gas supply is not available.
  • Oil: These reliable units are necessary for houses that don’t have access to the main gas supply. They are available as combi, system or conventional, and are perfect for larger properties in rural areas.
  • Gas: This traditional type is the most popular in the UK due to its reliability and the availability of gas. They are offered in the same forms as the soil type, making them accessible to most homes.
  • LPG: Powered by liquid petroleum gas that is stored in a tank, this is similar to a gas one, yet they are also good for properties that aren’t connected to the gas grid. They are powerful sources that cause less environmental damage than oil, yet they require higher maintenance and, subsequently, more money.


  • Home Necessities: You need to prioritize the needs of your household. For example, a combi boiler is great if you need to save space yet cannot supply a hot water demand. Size, storage space, and water/ heating requirements are the main things to consider.
  • Costs: The cost includes installation fee, fuel type, and running fees. The bigger and more components it needs, the more expensive it will be to install. For this reason, combination units are less pricey than conventional and system. When it comes to continuous costs, the electric boiler is the most expensive to run, and gas is the cheapest.
  • Environmental Impact: It’s no secret that heating is harmful to our environment, so you may want to factor this into your decision. Combis have reduced energy consumption, and electric units are the overall greener fuel type.

Installation and Maintenance

Hire a certified heating engineer to install your system to ensure maximum efficiency and safety. You also need to obtain any necessary certifications to protect you if there are any future issues.

Scheduling annual servicing from a professional is vital to extend the lifespan of your boiler. If you notice any unusual noises or inconsistent heating, don’t hesitate to consult a specialist.
