condensing gas boiler price


A good condensing gas boiler is a key component of your home heating system. It’s responsible for heating water, which is used to heat your home and provide hot water. This article provides an overview of how much it costs to replace a condensing gas boiler, including the average cost of new condensing gas boilers and how much they cost to run. There are many benefits associated with having an efficient boiler installed in your property; however, if you’re thinking about replacing your current model with one that incorporates a condensing function then it’s important to understand why this may be beneficial for you before making any decisions.

How much is a condensing gas boiler?

The price of a condensing gas boiler can range from around $1,000 to over $50,000. The price depends on the size and efficiency of the boiler, as well as how many features you want.

The size of the condensing gas boiler is important because they come in different sizes depending on how much hot water needs to be heated and how many radiators are being heated by it. If you have a large property with multiple rooms and bathrooms, then you will need a larger model than if you’re just using it for one room or bathroom.

Other things that affect its cost include brand name, installation costs (if needed), warranty (if any) and more. Each item listed above has an effect on pricing so make sure to look at these carefully when comparing models before making your purchase!

Is a condensing gas boiler worth it?

If you have a gas boiler, then it is likely that your boiler is not a condensing boiler. A non-condensing gas boiler will have an efficiency of around 65%, which means 35% of the heat produced by your heating system is wasted. Condensing boilers are much more efficient as they can extract 85% or even more of the heat from combustion and transfer it into your heating system.

There are a number of other options available to homeowners who want to reduce their energy bills and help protect the environment. Combination boilers combine a hot water supply with space heating into one unit, so there’s no need for two separate appliances in your home – this means you can choose either electricity or natural gas as fuel sources depending on what suits your needs best at any given time (and whichever gets cheaper!). Electric boilers are also becoming more popular among homeowners because they don’t require any ventilation; however, they do tend to be slightly less efficient than traditional gas-fuelled models due to smaller flues being required

What is the average cost of a new condensing gas boiler?

The average cost of a new condensing gas boiler is around £2800. This includes the installation, the price of your new boiler and any other associated parts such as flue pipes or radiators.

If you’re looking to buy a combi boiler from a manufacturer like Worcester Bosch or Vaillant, then you can expect to pay around £2200 for one installed. The actual price will depend on which model you choose and whether or not it includes all the necessary components such as an expansion vessel and flue kit.

A new condensing boiler typically costs around £2500 but this may vary depending on your specific requirements and whether or not there are any additional items that need installing such as extractor fans etcetera.

What are the disadvantages of a condensing gas boiler?

A condensing gas boiler is more expensive to install and run than an equivalent conventional boiler. It’s also not as efficient, which means it will be using more gas than a regular boiler would. Condensers are noisy, so you may find that your condensing boiler makes more noise than an equivalent non-condensing model.

Finally, the size of a condensing boiler is larger than comparable conventional models because there’s no need for header tanks or other bulky items that aren’t needed when all the heat produced by combustion is used to power your household appliances—so you have less room left in your home for furniture placement!

How much cost is a condensing gas boiler to run?

The running cost of a condensing boiler is the average cost to run a boiler, based on the amount you pay for your heating bills. The average running cost of a condensing boiler can vary from year to year depending on variables like gas prices and whether or not there are any government-funded incentives in place.

The average running costs range between £1,150 and £1,200 annually (about $1,370 – 1,440). However, if you want to know exactly how much it will cost per month or per week then we recommend using our calculator at the bottom of this page.

Is a combi boiler cheaper to run than a condensing gas boiler?

A combi boiler is more efficient than a condensing boiler. Therefore, you will use less fuel to heat your home.

Combi boilers produce less carbon dioxide when compared with condensing boilers. Carbon dioxide is one of the main causes of global warming, so this is another reason why a combi boiler may be more environmentally friendly than its competitor.

The running costs of a combi are lower because they don’t require an external venting pipe and flue to carry away fumes from combustion like condensing boilers do; these items add to the overall cost of installation and maintenance over time, which makes them more expensive in the long run (and not just for you).

How long do condenser gas boilers last?

A condensing gas boiler will last for 15-20 years.

This is a significant length of time, and it is why they are more expensive than a normal boiler. They are also more efficient with the use of heat, and they create less pollution in their production of heat.

What is the advantage of a condensing gas boiler?

A condensing gas boiler is an efficient option for heating your home. This is because it condenses the water vapour in the flue gases and then recycles it back into the boiler where it’s heated again before being dispersed through your central heating system. The result of this process is that you get much more heat from a smaller amount of fuel than would be possible with an ordinary boiler, reducing both energy bills and carbon emissions.

There are many other benefits to installing a new condensing gas combi-boiler:

  • It’s quieter than non-condensing boilers because there’s less noise in the flue system due to low levels of combustion air pressure (often as low as 0.3 bar). This means it’s easier on those living inside your home too! You’ll also notice reduced condensation build up on windows or walls during cold weather conditions around windows/doors which eliminates wet patches that can lead to mould growth over time if not kept under control effectively; in turn making sure they’re always kept clean so no one slips when walking by them either!

Replacing a condensing gas boiler costs?

The cost of replacing a condensing gas boiler is approximately:

£3,000 to £7,000 (combination boilers)

£3,000 to £7,000 (condensing boilers)

£4,000 to £10,000 (combined boiler systems)


The bottom line is that if you have an older boiler, then you may be able to save money by replacing the old one with a new condensing gas boiler. This will help to reduce your heating costs and make your home more comfortable. However, it is important to remember that there are some disadvantages of switching to this type of heating system such as higher installation costs and increased noise levels so it’s important for homeowners to weigh up all options before making their decision.
