Condensing boilers are a great option for home heating but they do have their drawbacks. Find out more in our guide.
Condensing boilers are light years ahead of older boiler types, meaning the get more heat from less fuel. When upgrading your heating controls and replacing a non-condensing gas G-rated boiler, you could save up to £380 per year. But does it make sense for your home?

If you are aware of the world’s environmental problems and want to save some money whilst doing your bit, an oil or gas condensing boiler might be right. Due to advances in engineering, these modern boilers are able to use heat more economically.
Most modern oil and gas boilers are condensing and unlike the older non-condensing type, they operate at 99% efficiency using multiple heat exchangers to squeeze all the heat possible out of the fuel.
Condensing Boiler Types
A modern condensing boiler comes in two different types: the system boiler and a combi-boiler. If you have a water tank to store hot water, you can easily combine it with a system boiler. System boilers are an efficient and beneficial solution for large households that have two or more bathrooms and a high volume of water consumption.
How A Condensing Boiler Works
The main principle of a condensing boiler, is that the vapourised steam condenses into heat instead of going through the flue and being wasted. After that, the steam passes through a heat exchanger which cools it off and condenses it back to a liquid form. The heat warms up the water that is pumped from the mains.
Among all the types of boilers available on the market, the condensing boiler is the most effective and energy efficient. Due to the advanced combustion technologies, condensing boilers reduce the level of nitrogen oxide and carbon monoxide thrown out into the atmosphere.
Condensing Boiler: Prices
The average price for condensing boilers, excluding the installation costs, can vary between £1,500-2,500. This is a significant investment, but it will pay off within the period of 10 years. Condensing boilers will help save between 10% and 12% on your energy bill every year.
Whilst the initial cost of a new condensing boiler can be a little high, in the long run, they are a wise investment that will pay off by reducing your energy bills and saving hundreds annually.
The Pros & Cons
Condensing boilers have come along way in recent years and with EU regulations encouraging more efficient central heating systems, the drawbacks to buying a modern gas or oil condensing boiler are minimal.
Condensing Boilers: The Advantages
Condensing boilers are designed to reduce the emissions of greenhouse gases which helps prevent the development of global warming.
By reducing energy waste a modern condensing boiler improves the home energy efficiency and helps reduce your home heating bills.
A condensing boiler heating system is completely sealed and the air that it uses comes from the outside. There are also safety measures installed on a condensing boiler such as heat sensors, which switch the system off if they detect any failure
Condensing Boilers: The Disadvantages
In very rare occasions, the condensation pipe which siphons off acidic waste water, can become frozen due to external weather conditions. This can be easily fixed by pouring warm water over the frozen area.
Find A Local Installer
Condensing boilers are a modern energy efficient, eco-friendly product, and provide you with multiple benefits. If you consider installing a condensing boiler in your home, it is crucial that the task is performed by experts. In this case, you will need to find a reliable company that can install a condensing boiler safely and will guarantee a high level of quality.
