Condensing boiler overview

Condensing boilers extract the maximum amount of heat from the combustion process. In contrast to non-condensing boilers, which discharge waste gases into the environment, condensing boilers condense these gases into water, releasing additional heat in the process.

Hisory of Condensing Boilers

Condensing boilers have been available for over three decades. They started to gain popularity in the UK during the 1990s following changes made to building regulations. While initial condensing boilers were less efficient than current models, technological developments have resulted in boilers that can be up to 98% efficient.

Efficiency of Condensing Boilers

Condensing boilers are highly efficient, with a potential efficiency rating of up to 98%. This is because they can extract more heat from the combustion process by condensing waste gases into water. This means less fuel is needed to heat your property, while fewer waste gases are released into the atmosphere. Condensing boilers can achieve greater efficiency when installed with smart controls, such as a smart thermostat and smart radiator valves.

Cons of Condensing Boilers

Possible Condensate Issues

Condensing boilers produce condensate, which must be drained properly. If the drainage system becomes blocked and backs up to the boiler, it will stop the boiler operating. If the condense pipe is installed outside of the property it can freeze in very cold weather and also cause the boiler to stop operating.

Sensitivity to Water Quality

Condensing boilers can be sensitive to water quality, and hard water can cause scaling or other issues that can reduce their efficiency or lifespan.

Installation: Condensing boilers require professional installation to ensure they are installed safely and correctly.

 

Maintenance: Make sure you have your condensing boiler serviced regularly to keep it running smoothly and efficiently.

Summary of Condensing Boilers

In conclusion, anyone wishing to efficiently heat their home while simultaneously doing their part to protect the environment should choose a condensing boiler. They are frequently regarded as being more effective than air source heat pumps. They can also provide a more comfortable living or working area, as well as long-term cost savings on energy bills.

While gas is currently the most practical heating choice, it is crucial to remember that it will likely be phased out in the future. Condensing boilers are still the best option for heating your home at this time.

I had received an extortionate quote from another company and wanted to compare it to Master Gas London. I spoke with Ed and he was so knowledgable and honest. He took the time to explain the different boiler options and let me know the pros and cons of the different boilers. He was very patient and I am so appreciative of the time he took with regards to the choices I could make. It is such a shame I am located too far away to use this company, as their professional response and advice was outstanding.

Highly recommend. Could not fault Ed and Tamer. They were efficient, on time, went out of their way to ensure we were pleased with the work, and took time to explain the new system. The work was finished to a high standard and all pipework routed beautifully.

I was very anxious about my boiler to be fixed properly until I found Ed from the first telephone call, my anxiety has been eased off immediately because he was so polite, explained potential issues and he tried to book me in as quickly as possible even though he is very busy. He was so professional from beginning to end. At the site he investigated the problems and explained to me the issues and he didn’t leave until everything was sorted out properly. Today I was able to take a comfortable bath for the first time in a long time. Thank you Ed. Highly recommend and will definitely recommend to my friends!

Ed and team came to install a new boiler a few months back and I've been meaning to leave a review ever since because they were so great. Worked all day and didn't leave us until everything was working. They are more than happy to stay in touch if there's any follow ups too which is great.

FAQ'S

A condensing boiler, is a type of boiler that needs less fuel to produce heat. Heat that would ordinarily be lost while heating water is captured and recycled.

Condensing boilers function by capturing and recycling the heat that would otherwise be wasted during the water heating process. This is accomplished via a secondary heat exchanger, which enables them to attain superior efficiency levels.

Condensing boilers are typically more efficient compared to non-condensing boilers, with the capability to reach efficiency ratings of up to 98%. This can lead to noteworthy long-term energy savings.

The lifespan of a condensing boiler can fluctuate depending on multiple factors, including the frequency of usage, the installation quality, and the maintenance level it obtains. Nevertheless, a condensing boiler can last for up to 15 years or longer with adequate care.

Condensing boilers do require some special considerations when it comes to installation and maintenance. They require a condense pipe which must drain to waste.

Your property’s size, number of radiators and bathrooms will have an impact on the size of condensing boiler you need. To find the right size for your specific requirements, speak to a member of the team at Master Gas London or feel free to use our fixed price instant quote tool.

Yes, because they emit less carbon than non-condensing boilers, condensing boilers are considered an environmentally friendly heating alternative. They are also capable of achieving up to 98% efficiency. When combined with a smart thermostat and smart radiator valves, they can achieve even more efficiency.

Several variables, like the condensing boiler’s size, brand, and installation needs, will determine the price. The price for a condensing boiler will range from £500 to £2,500 or more.

Retrofitting a condensing boiler to an existing heating system is possible, but it may require adjustments to the current setup.
