What exactly is a condensing boiler, and how does it differ from other options? This article will walk you through the steps and explain why they are so good for both your house and the environment.
What is the definition of a condensing boiler?
A condensing boiler is a kind of boiler that is often seen in today’s houses. The boilers may collect gas produced by the combustion of fuels such as gas and oil and utilise it to heat water entering the system, saving money and lowering carbon emissions. The sole difference between a condensing and a non-condensing boiler is the quantity of usable heat it generates, as well as the fact that they can attain energy efficiency of over 90%.
What is a condensing boiler and how does it work?
Your boiler will run on either gas or oil, and once ignited, it will begin to burn. It achieves this by transferring heat from the burner to a main heat exchanger. The heated air passes through the heat exchanger and is held there as long as possible to raise the temperature. This heat will subsequently be transferred to your radiators.
In addition, the heat passes via a secondary condensing region, which is not present in other kinds of boilers. The heated air condenses, resulting in droplets of water vapour, which are collected and carried away to be disposed of by a drain. This is one of the most significant benefits of a condensing boiler, since no other boiler can match its efficiency.
Condensing boilers are designed to recover more heat before it escapes the system. The heat that exits the chimney of an older boiler is likely to reach above 200 degrees Celsius. It’s down to roughly 55 degrees Celsius now, thanks to a modern, condensing boiler. Condensing boilers are excellent at recycling heat to raise the temperature of the returned cold water.
So, how can I determine whether or not my boiler is condensing?
Whether you have a boiler in your house and aren’t sure if it’s a condensing boiler or not, there are a few things you can look for in your present system or in the handbook for your boiler.
When was it put in place?
If your boiler was placed in your house after April 2005, it will be a condensing boiler due to the restrictions in place at the time. After this date, all boilers produced are condensing.
Examine the flue.
If your boiler has a metal flue for expelled gases, it is most likely non-condensing. Condensing flues are normally located on the outside of your home or on your roof.
Drainpipe and steam.
If you can see steam pouring from the flue through an exterior wall (or roof) and there’s a white plastic line running to a drain, you’re dealing with a condensing boiler.
If you don’t have a condensing boiler or if your present system is more than 10 years old, you should think about upgrading. You’ll be considerably more secure if you replace your system with a newer, more efficient one. This manner, you can be certain that your boiler will function properly during the chilly winter months.
What are some of the advantages of using a condensing boiler?
When opposed to earlier boilers, a condensing boiler offers a slew of advantages. As previously stated, there is a greater energy efficiency rate of over 90%, which instantly jumps out as a significant advantage. Here are a few more reasons why you should choose a condensing boiler:
- Money savings – as a result of the energy and heat saved and recycled, your energy costs will be reduced.
- Wireless programming – for convenience, your thermostat may be operated wirelessly. They can detect the temperature of the air and adjust your heating as required.
- Space-saving – your boiler may be easily concealed and will not take up a lot of room.
- Reduce your carbon footprint – the 90 percent efficiency rate will once again reduce your carbon impact.
Is it true that all new boilers are condensing?
All new gas boilers installed in the United Kingdom must be condensing boilers from April 1, 2005. For oil boilers, the same regulation has been in place since April 1, 2007. The new laws were put in place to address climate change, with families accounting for an estimated 40% of UK emissions*.

If you’re still using an older boiler, it’s well worth the expense since every newly installed boiler is condensing. We’ve gone into great depth about how efficient it may be, not just for your home but also for the environment. The advantages are undoubtedly many!
