A condensing boiler is a modern type of boiler specifically designed for more efficiency. Since it is made from “condensing technology”, it is called a condensing boiler. Throughout the UK, condensing boilers are very common. People are reaping their benefits and saving energy. Majority of these boilers are gas-condensing combi boilers. So if you still haven’t replaced your old non-condensing boiler, do it right now through government grant for boilers.

Condensing boilers are not only efficient but also environmentally friendly. They help you reduce your heating and hot water costs. On top of that, they are safer than older non-condensing boilers. Moreover, in 2005, the UK implemented regulations that made it compulsory for all gas boilers to be condensing.

On the other hand, there are old G-rated non-condensing boilers. These are no so much efficient. Rather, they’re potentially more harmful. So, switching to a new high-efficiency condensing boiler is the need of the hour. Everyone is opting for condensing technology. This in fact, enhances your heating controls. And it can result in substantial savings of over £300 on year basis.

First Condensing Boiler in the UK

In 1970, the UK was going through oil crisis. Boiler manufacturing companies too coped with huge pressure. They wanted to design a boiler that did not consume lots of energy. Plus it wasn’t too expensive. So, these companies started testing and trying new technologies. They played with lower temperatures for boilers and looked at how the hot water inside the boiler could get hot. They also experimented on technology by keeping outside weather in due consideration.  

Finally, after a lot of struggle, in the 1980s, they came up with the first-ever special boiler from condensing technology. No doubt, this new kind of boiler was more energy-efficient. Also, it was not too expensive. As a result, condensing boilers became a reality.

How Many Types of Condensing Boilers Are There?

Well, fundamentally there are two kinds of condensing boilers. First, there are system or regular boilers that use the existing hot water cylinder. Next, we have got combi boiler. With combi boilers, we can take out the old tanks. What’s more, this boiler makes hot water whenever we need it. In other words, it fulfills our demand of hot water on urgent basis.

A system boiler on the other hand, works with a cylinder to give us hot water. It doesn’t have a separate hot water heat exchanger. Moreover, it comes with an expansion vessel and pump. So it makes system boiler more suitable for installation in a sealed system.

How Condensing Boiler Works?

Undeniably, non-condensing boilers wasted 30-50% heat. Moreover, the hot gases escaped into the flue. But, thanks to modern condensing technology, a condensing combi boiler is up to 99% efficient. So, how does it manage all this?

Well, it is chiefly because of condensing technology these boilers use. They outperform when it’s getting colder outside. This is the magic of the technology they use. And that’s how they got their name. A special pipe, the condensate pipe, takes away this condensation. It directs it to the waste water system.

Further, these boilers can catch more heat from the exhaust gases. For the same reason, they use a surface to transfer as much heat as possible from the boiler’s burner. So in this way they create useful heat and bound it stay inside, not escape.

What’s more, these boilers use the latest technology to emit nitrogen oxide and carbon monoxide. A condensing boiler gets the heat from the flue gases and then uses it again in the heating system. During this process, the flue gas cools down from around 130℃ to 50℃.

What’s interesting about condensing boilers is that they have the potential to recycle existing energy. This helps you save money on your energy bills. So by using these boilers, you’re doing your part to fight climate change by reducing CO2 emissions. Thus condensing boilers are not merely efficient; they’re good for your budget and the planet.

What size condensing combi boiler do I need?

Well, it depends on your need. When you’re picking a condensing combi boiler, you need to think about two important things. First, how much hot water you use. Second, how many rooms you want to keep warm.

For a house with 2-3 bedrooms and one bathroom, a 24-30 kW boiler is a good fit. It heats your water and keeps your home inviting. But, if you have more rooms or another bathroom, you better go for a bigger boiler, around 30-35 kW.

Moreover, if you want to replace your non-condensing boiler, ECO Energy Services can help you. They’re experts in helping people apply for free boiler grants.

How long do condensing boilers last?

No doubt, the lifespan of a condensing boiler depends on several factors. First, what’s the model, and how the company manufactured it? Second, how much you use it. Next, you can make it last longer through regular service. Further, always hire a Gas Safe registered heating engineer to service your boiler.

Also, it’s a good idea to check the warranty of your boiler. Make sure it’s a good quality one. For example, Worcester Bosch boilers often have warranties from 5 to 10 years. This gives homeowners peace of mind.

Condensing Boiler Prices

Condensing boilers cost around £1,500-2,500, plus installation. Truly, they cut 10%-12% off yearly heating bills. Although a new one seems expensive, it pays back over time. As a result, you can save more money on an annual basis. Usually, this investment usually pays off in 10 years.

Condensing boilers offer environmental benefits. They enhance efficiency by up to 12%. Next, they recycle waste gases. Consequently, they contribute to future energy bill savings.

Moreover, they save space as condensing combi boilers eliminate the need for a hot water tank. They come in various compact sizes. This makes them more suitable and convenient to fit into a kitchen cupboard compared to conventional boiler models. So prices may vary from brand to brand.

How to Choose the Right Condensing Boiler?

Choosing the right condensing boiler might feel a bit confusing, but we’re here to simplify it for you. Consider these key factors:

Firstly, there are three main types of boilers: combi boilers, system boilers, and regular or conventional boilers. While all combi boilers are condensing, there are slight differences between them.

Now, think about the fuel your boiler will use. It could be electric, gas, or oil. Check what’s available in your area, as it impacts efficiency and cost. Do a bit of research to make sure you choose the right fuel type. Also, ask yourself if you truly need a condensing boiler. So are you ready to handle its intricacies? Well, always consider the pros and cons we mentioned earlier.

Once you’ve covered the basics, compare different models. Furthermore, check the following:

  • Warranty Period: Look at the warranty and see to how long it lasts and what it covers. It is because many things can go wrong.
  • Efficiency Rating: This shows how well the boiler turns fuel into usable energy. Indeed, higher ratings are better.
  • Wattage Output: This is vital for any boiler, whether condensing or not. So match the wattage to your heating needs.
  • Customer Reviews: Reviews matter a lot. So see what others say. Reviews are like a sneak peek into what to expect.

So, these are the simple steps to choose the right condensing boiler for your home!

Conclusion

To sum up, condensing boilers are a good choice because they capture as much heat as possible from burning gas or oil. Moreover, they stop the heat to stay inside and does not escape into the air. However, these boilers stand out as efficiency champions compared to their non-condensing counterparts. They not only save money on heating bills. But they also contribute to the environment. Furthermore, in the UK, the government mandates that every new boiler is a condensing model in the country.

On the flip side, the lifespan of your condensing boiler depends on factors like its build quality plus usage. It is true regular care and an annual checkup can extend its life expetency. Nevertheless, concerning size, condensing boilers vary from 24 to 42 kW. In short, choosing the right size depends on your home’s heating and hot water needs. Without a doubt, its like finding the perfect fit for your home’s welcoming warmth.
