What is best condensing or combi boiler?

Is there a difference between a condensing and a combi boilers?

Customers frequently ask us this topic, as well as what the difference is between a combi boiler and a condensing boiler.

The first question is answered in the no. The answer to the second question is that there are several distinctions since a combi boiler is a type of boiler, whilst a condensing boiler refers to the procedure that a boiler employs to boost efficiency. All combi boilers installed in the UK must now be condensing boilers; however, not all condensing boilers are combi boilers; they can also be system or ordinary boilers.

If your boiler has suddenly failed after 20 years of service and you’ve never had to shop around for a new boiler, we don’t blame you for being perplexed and mistaking combi boilers with condensing boilers. Don’t worry, we’ve produced this blog to address all of your concerns. You can also visit our guide what is boilers how do they install and works.

 There is no distinction between a combi boiler and a condensing boiler; they are virtually interchangeable. All new boilers use condensing technology, so you won’t have to choose between a combi and a condensing boiler when purchasing your future boiler. You will receive both! Ideal Heating provides all you need to know about combi condensing boilers in this article.

What Exactly Is a Condensing Boiler?

A condensing boiler absorbs waste gas heat and uses it to warm up the water returning to the boiler, using less energy to reheat the water that circulates through your central heating system. It also produced a considerable quantity of carbon emissions, a greenhouse gas that contributes to climate change. Boiler Plus regulation was enacted in 2005 in response to rising energy costs and environmental concerns. This meant that all new boilers had to be condensing, which dramatically increased boiler efficiency.

How Do They Work?

To generate heat, a condensing boiler consumes fuel. Hot water heated by a condensing boiler circulates via pipes in your central heating system to warm your home’s radiators. When this procedure is finished, the cooled water is fed back into the boiler and passed through a heat exchanger to reheat it again. The heat created by the flue gases powers the heat exchanger. As a result, less fuel is required to power the burner – but how does this work?

Waste gas is swiftly cooled as it is created during combustion and as the water is heated. Don’t worry, none of this heat is going to waste. Instead, the waste gas’s heat energy is dissipated by condensation. This thermal energy is needed by your condensing combi boiler to keep your central heating running.

So, what becomes to the waste gas and water vapor? The cooled waste gases are discharged into the atmosphere via the flue pipe, and the water vapors from the flue gases is caught and converted into a liquid. The waste water exits the system via the condensate line of the boiler.

That’s all there is to it! As you can see, condensation is important in the technique that provides the term “condensing boilers.” A condensing boiler’s key advantage is that it loses far less energy, making it a more efficient heating system. A condensing boiler not only reduces your carbon impact, but it also reduces your energy expenditures.

What exactly is a combi boiler?

The most prevalent kind of boiler installed in UK homes is a combi boiler or combination boiler. The name “combi” boiler refers to its ability to deliver both hot water on demand and heating water from a single unit. Combi boilers, unlike system boilers and conventional (heat-only) boilers, do not require a separate hot water storage cylinder or an overhead tank in the attic, and all components are internal. This means they take up less room and are therefore excellent for smaller homes, with some even fitting into the typical sized kitchen cabinet.

What is a Condensing Combi Boiler?

Condensing technology is currently used in all modern household boilers, including combi boilers, system boilers, and conventional boilers.

All household boilers emit hot waste exhaust gases that escape the boiler through the flue; however, all new boilers include a Flue Gas Heat Recovery System, making them condensing.

All condensing boilers are at least 90% energy efficient, making them 40% to 50% more efficient than older non-condensing ones. They can reuse heat from flue gases, are healthier for the environment, and can help you save money on your heating expenses.

Advantages of a Condensing Combi Boilers

  • Reduce your energy waste and heating costs.
  • greater energy efficiency
  • Lower your carbon impact.

Disadvantages of a Condensing Combi Boilers

To summarize, a combi boiler may not be appropriate if:

  • You have a large need for hot water, such as more than one bathroom.
  • Your mains water pressure is low.
  • Your plumbing is incompatible.

Which Is Better: Combi or Condensing Boilers?

Condensing boilers, particularly combi boilers, are extremely efficient since they utilize less energy during the heating cycle.

So, if you’re asking whether combi boilers are superior than condensing boilers, the answer is no. The only thing you need to think about is the sort of condensing boiler you want: a combi, conventional, or system condensing boiler. If you want to learn more about combi boilers. If you are looking to improve your energy performance or want to upgrade your old boiler to new one then you are on the right place. Contact us and we will happy assist you.
