Condensing Boilers Prices & Reviews 2022

Condensing Boilers Prices

Condensing boiler prices can be expensive, but did you know that it’s entirely possible to find a good quality condensing boiler for less than £700?

That said, buying the right condensing boiler is important and the one you choose is ultimately dependent on many different factors. One of the most important factors is finding the appropriately sized condensing boiler that fits your budget and services your needs.

But why should you consider buying a condensing boiler in the first place?

There are many different options on the market, but a condensing boiler has unique advantages such as having the highest energy efficiency ratings and complying with new legislation – both important reasons to choose this type of boiler for yourself.

Important note: All new combi boilers are condensing boilers, this was made law many years ago, so there’s really no need to be too concerned about securing one with condensing technology as all modern boilers have it by default.

What is a Condensing Boiler?

Between April 2005 and 2007, the UK government passed laws stipulating that all new or replacement gas and oil-fired boilers installed should be condensing boilers.

This simply means that they use condensing technology, which compared to old boilers makes them far more energy efficient and in turn helps to reduce heating bills and carbon emissions.

How do Condensing Boilers Work?

It’s called a condensing boiler because of the condensing wastewater vapour process that occurs within the boiler. The condensing of this heated wastewater allows the boiler to retain its latent heat for longer, thus making it more efficient.

In old boilers this waste water vapour was lost via the exhaust fumes and rendered them only around 60% efficient, while new condensing models are now always at least 90% efficient.

This drastically cuts the amount of energy used and positively affects your carbon footprint.

Naturally, these laws and raising the standard of boiler efficiency were part of an initiative to make better use of energy in the UK, with many other European countries following suit.

It’s a good thing, despite the fact that it may cost a bit. This spurred the development of a new energy efficiency ranking system, in which condensing boilers take the lead position with their ‘A’ grade.

Condensing Boilers vs Traditional Boilers

Is there a difference between a condensing boiler and the traditional boiler you have always had? The answer is a great resounding, “yes!” Traditional boilers simply heat the water without any measures in place to catch the water vapours released.

These vapours are responsible for heat loss and unnecessary energy consumption. Condensing boilers condense these escaping vapours and trap the latent heat. This increases the thermal and energy efficiency by a surprisingly large margin.

This is an extremely simplified explanation of how a condensing boiler differs from a traditional one. There are many more variables that have to be taken into account to maximise efficiency, reliability, cost and durability.

These factors include but are not limited to design, materials, and installation methods. Innovations in technology mean an ever-evolving condensing boiler that can be described as ‘super-efficient’ and ranking as ‘AAA+’ in the European Union ranking system.

Condensing Boiler Efficiency

The main selling point of a condensing boiler is its thermal efficiency, with many manufacturers claiming to provide thermal efficiency levels of up to 98%.

On the lower end of the spectrum, condensing boilers can achieve at least 90% thermal efficiency. This is in stark contrast with traditional oil-fired and gas-fired boilers, which only have a thermal efficiency of around 70-80%.

But how much of an impact does switching to a higher thermal efficiency boiler really have on your carbon footprint? The answer is much more of an impact than you think!

Traditional boilers produce a whooping one-sixth of the UK’s carbon dioxide emissions. Switching over to a condensing boiler would have a colossal effect on the UK’s carbon footprint.

To give you a quantitative idea of the impact, the changing boiler standards and laws within the EU stand to cut carbon emissions by 400 million tonnes per annum.

How Does This Benefit Me?

An obvious benefit to having a thermal and energy-efficient boiler in your home is the reduced energy bill – so yes, it does benefit you!

As outlined above, the impact of switching to a condensing boiler on the environment is excellent. It’s a relatively easy way to change the impact of your lifestyle and reduce your carbon footprint.

You’re saving hard-earned money and the planet; it’s a win-win situation.

Power Output and Condensing Boilers Pricing

Logically, your energy bill will be higher if your boiler produces more energy. Therefore, the energy output of a boiler is an essential factor to consider when choosing a boiler that will suit your needs.

Other factors that strongly influence condensing boiler prices include the boilers dimensions, flow rate and efficiency rating.

When it comes to pricing, you will notice that the higher the output, the higher the cost. In the UK, top brands of condensing boiler prices are Valliant, Potterton, and Worcester Bosch and the prices vary from £500 to £1,700.

Here is a table comparing some of the most popular condensing boiler models, along with their power outputs and the condensing boiler price:

Worcester Bosch Greenstar Highflow 440CDI 44/55 £1,644.39
Glow Worm Flexicom sx 31 £900
Valliant EcoTec Pro 24 NG 24 £744.86
Baxi Duo-Tec 24 HE 24 £726.48
Potterton Promax 12HE Plus Slimline 11.8 £553.72

It is important to consult with a Gas Safe engineer to determine precisely what boiler suits your needs before making a purchase.

Why Do I Need a Condensing Boiler?

To put it simply, it’s the law. New properties are required to have a high energy efficient condensing boiler under new building regulations.

Enforcement of this law may seem harsh, but the reasoning behind it is that you’ll save tons in money and energy over time and as the country aims to become increasingly more environmentally aware, it’s simply the right thing to do.

There are many brands and makes on the market to suit your specific heating needs. With the guidance of a qualified heating engineer, you can find the perfect condensing boiler price to suit your budget.

Condensing Boiler Pros and Cons

Still not convinced that you should make the leap? Let’s weigh the pros and cons!

The cons:

  •  Condensing boilers can cost more than other types of boilers, including traditional oil and gas-fired boilers.
  • If not properly maintained, future maintenance and repair costs can be high.

The pros:

  • On the brighter side, condensing boilers can drastically cut your energy bill. You can potentially save hundreds of pounds every year.
  • Not to mention, condensing boilers have the highest energy efficiency SEDBUK rating of up to 90%. And to top things off, buying a condensing heater is compliant with new legislation.

Condensing Boilers Prices Final Thoughts

With condensing boiler prices starting at around £500 and with the energy and cost saving implications of getting one, it’s a sound decision to make for your finances and the environment.
Bear in mind that all new, modern boilers are now condensing by law, but if you do have an older G-rated model that’s more than 10 years old, it’s likely worth making the upgrade sooner rather than later.

In fact, according to the Energy Saving Trust swapping your old G-rated model for a new boiler that’s A-rated can make a huge difference:

“By trading your old boiler in for a modern boiler, you could save around £340 and a hefty 1,500kg of carbon emissions a year.”
