As the UK’s leading supplier of gas boilers, we know how important it is to find the right one for your home. That’s why we’ve put together this handy guide on what makes a great boiler, and what you should look out for when choosing one.

What is a gas boiler?

A gas boiler is a heating appliance that uses the heat of combustion to heat water. Gas boilers can be used to provide space heating, domestic hot water and central heating for a building.

Gas boilers are more efficient than electric or oil boilers because they have an extremely high thermal efficiency (typically around 93%) compared with other types of boiler. The use of natural gas in a typical UK home will reduce CO2 emissions by approximately half compared with oil burning systems.

  • Riello

Riello is one of the most popular boiler brands in the UK, thanks to its wide range of products and high-quality boilers. The company was founded in Italy back in 1814, when Giovanni Battista Riello started making heating systems for local farmers. More than 200 years later, it’s still one of the leading manufacturers in Europe and has expanded into other parts of the world—including North America and Australia.

  • Worcester Bosch

Worcester Bosch is another brand that makes high-quality boilers with an emphasis on energy efficiency (and thus reduced operating costs). The company was established 100 years ago by a German engineer named Carl Heinrich von Siemens; today it has more than 2200 employees across three continents (Europe, Asia Pacific and North America).

The best gas boiler for you is one that meets your needs, fits in with your lifestyle and does not cost more than it needs to. If you want reliability and efficiency, then consider a condensing boiler. But if you need a fast recovery from periods of low water flow, then an instantaneous system may be better.

If you want a boiler that is environmentally friendly, then condensing boilers are definitely your best option. If you want to save money on fuel bills, then consider a condensing boiler.

Choosing a boiler is not as easy as it seems. There are so many options on the market that it can be difficult to know which one is right for you. To help you make an informed decision, we’ve put together this guide to what makes a good gas boiler and why efficiency matters in terms of your choice of heating system.

Efficiency versus capacity

We often talk about boilers having high performance ratings when talking about their efficiency. You might have heard the term ‘80% efficient’ or ‘90%+ efficient’ before when discussing boilers, but what does this actually mean? In simple terms, efficiency refers to how much energy is delivered from your boiler compared with how much energy was used in heating your water in the first place (the latter figure being called input). So if a boiler has an input/output rating of 100%, then every single unit of gas will produce one unit of hot water at its outlet – no more and no less. If its output/input rating drops below 100%, however, then some heat will be lost during combustion and therefore wasted energy will be present within both ends of the pipe network – reducing overall efficiency further down stream still

What type of boiler is cheapest to run?

It’s important to consider how much your boiler will cost to run, as well as how efficient it is. This is because you’ll pay for the energy used in your home, whether or not the temperature remains at a constant level.

Your choice of heating system should be based on how much gas or oil you use, what heating systems are available in your area and what type of property you live in. There are many different types of boilers available:

  • A gas condensing boiler works by creating hot water from natural gas through a process called condensation. The heat pumps out into radiators or underfloor heating systems to keep rooms warm while reducing fuel consumption by up to 30%. However, they tend to be more expensive than other types of boilers.
  • A gas combi boiler combines hot water production with central heating so that one appliance provides both services (hot water supply and central heating). This reduces installation costs compared with having separate units installed separately but can still be quite expensive compared with other options such as heat pumps or solar panels

How long should a gas boiler last?

How long should a boiler last?

The average life expectancy of a gas boiler is 20-25 years, though it depends on the brand and model. If you want to know exactly how long your boiler will last, we recommend getting it checked by a professional once every 12 months.

Some boilers can last longer or shorter depending on the brand and model. If you’re in doubt about whether your current boiler needs replacing, call us today for advice from one of our qualified engineers.

How to choose the right gas boiler?

The first step is to determine how much you will be paying for your gas boiler each month. To do this, you need to consider the following:

  • How efficient is the boiler?
  • What are its maintenance and replacement costs?
  • Are there any extras that you might want or need from the manufacturer?


Now you know what to look for when choosing a gas boiler and can make an informed decision. A good quality boiler will last you many years, saving money on energy bills in the long run. It’s important that you take your time when making this choice as it will affect how much money you spend on heating bills every year!
