What actually is a combi boiler?

A combi boiler, or a combination boiler, can do multiple jobs at once, as the name suggests. This kind of combi boiler will control both your hot water and your heating, which is why they are more efficient and reliable.

Combi boilers will deliver hot water and heating instantly on-demand as they do not require a hot cylinder to be heated up beforehand.

These kinds of boilers are preferred nowadays as they can really make a difference to your home and ensure that you will always be warm and cozy whenever you need to be.

With this information in mind, it is very likely that you will want to replace your old boiler with a shiny new combi model instead.

If this applies to you, then you will be looking to convert your regular boiler to a combi one; which is essentially industry-speak for replacing your boiler.

Converting a boiler can cost between £2,500 and £4,500 depending on the company you choose and other needs we mentioned earlier.

Replacing your combi boiler is something that is top of the priority list for most homeowners in the United Kingdom, so we know what kind of demand we are dealing with here.

What am I paying for here?

When it comes to replacing an old boiler for a new combi one, there are a lot of steps involved, which is why it can be quite expensive.

To keep things simple, replacing a boiler includes:

  • Full removal of your old boiler system and water cylinder
  • Upgraded and new pipework fed into the existing location or a new one if required
  • The cost of your new boiler itself

There are some other fees that can come with this service but that doesn't mean that it isn't worth it.

Replacing a combi boiler is a big job that can take a couple of days and two or more engineers in your home, for simple combi swaps this can be done in as little as half a day.

Types of boilers available

There are lots of different brands and models available and it can be quite overwhelming for a novice to wade through.

The boiler engineer should be able to guide you to the best model for your home, so make sure you take their advice. They will consider the kind of house you have, but may not necessarily consider your budget so make this clear.

When looking into new boilers, there are lots of different complicated names out there.

iHeat have lots of models on offer, but here are some of their main brands that you will probably have to choose from:

How much do new regular/system boilers cost?

A new regular boiler (also known as a system boiler in the industry) can cost between £1,500 and £3,000 depending on the factors we have already mentioned.

You will not be able to get a clear quote unless you speak directly with the boiler company and give them information regarding your own personal situation.

The final amount of installing a regular boiler into your home can be affected by various different factors:

  • The brand of the boiler
  • The warranty length (iHeat offers form 5 - 10 year warranties)
  • Required controls (wireless or wired)
  • Any additional pumps or valves needed
  • The complexity of the job (such as removing of an old tank)

Regular or system boilers require a water cylinder in order to work, which is one of the main differences between these and combi boilers.

This means that a water cylinder will also have to be installed into your home, which will, of course, come with additional costs.

The figures we have given, as well as those that you will likely be given from a boiler company, only cover the installation of the regular boiler, not the water cylinder.

So you will need to sure that you have enough in the bank to cover your new boiler installation and then some if you are looking to get a regular or system one.

How much does a back boiler to combi conversion cost?

If you are currently dealing with a broken back boiler in your home, then you really need to get someone in to sort it out. This is a problem that no modern home should be dealing with.

Back boilers have had their days in the sun, but now they are causing more problems than they are worth.

These kinds of boilers can no longer be repaired in accordance with the modern regulations boilers now need to keep up with, so there really is nothing you can do about this problem other than replacing it with a new combi boiler.

In most cases, replacing a back boiler with a combi one can cost anywhere between £3,000 and £5,000.

Most companies will also have an additional fee on top of this when it comes to replacing a back boiler.

This is because this is such a complicated process and the pricing needs to reflect that.

The quote that you receive from some boiler companies may not include this additional fee, so make sure you have a bit more in the bank than they are asking for to keep yourself covered.

The actual process of converting a back boiler system to a combi boiler one is quite similar to any other replacement, as it also includes the entire removal of your current boiler before the new one can be installed, just the cost may differ.

This includes replacing the pipework and all of the other complicated bits that go with a boiler, you wont get any hidden costs with us.

However, the fact that a back boiler is inconveniently located behind your fireplace makes this a very complicated task and one that most companies do not enjoy doing.

This is why you can expect a much higher cost of boiler for this kind of boiler service, as there are more steps involved than replacing the system.

Most boiler companies will charge such high prices for this kind of service as it makes the task slightly easier to bear when you know there will be a nice pay-check at the end of it.

How long should a boiler last?

As you can see, replacing or installing a new boiler can cost a lot of money, so you want to make sure that it is worth it.

Luckily, gas combi boilers aren't something that you need to be buying on a regular basis as they are made to last around 10-15 years.

This is an average figure and one that applies to standard homes who use their boilers as regularly as you would expect a normal family home to do so.

Of course, there will be some exceptions to this, but as a standard rule of thumb, your boiler should last you at least a decade.

This lifespan applies to all fuel boilers, such as oil, gas, and LPG, as well as all combi and standard.

This means that no matter what kind of boiler you choose for your home, you should be able to keep it warm and cozy for at least a decade before forking out for it all over again.

Typically you should be aiming for a 5-10 year warranty on your boiler, this will cover you through the manufacturer if there are any faults on your new boiler.

However, this doesn't apply to everyone and, as you can imagine, there are some strict requirements in place to see whether it is something that you actually need.

This can come free of charge or at a cost that has been significantly cut based on your circumstances and how you qualify.

If you do qualify for this service, the government will arrange for a local engineer to come round your house and install a new (probable combi) boiler system in your home.

This is a plan that has been aimed at those who are the most worse off in our society to ensure that everyone has access to a warm and safe home - which is vital in our ever-changing weather conditions!

There are various regulations in place, as we have mentioned, including the kind of benefits that are supported and the postcodes that qualify.

You may qualify for a free or vastly reduced new combi boiler in your home, so make sure you take some time to fill out the relevant applications as this isn't something you want to miss out on. This is a free to use service, so there really is nothing to lose.
