Do I need a new boiler or should I repair my current one?

The question that we all juggle in our minds is do I really need to replace my current boiler and trade it in for a shiny new model has this current boiler not served me well? Can I not squeeze a few more years out of it maybe…  

Well the answer literally boils down to these main factors, has the boiler been having its annual service to keep them kilowatts on the clock and depending on the brand of your boiler has it reached its boiler lifespan of between 10-15 years?

Thinking of replacing your back boiler, look no further we have a guide on the main reasons why you should trade your old boiler in for a new combi boiler that will be more efficient and also save you money. 

A study was carried out by the BEIS (Department of Business, Energy and Industrial Strategy) which showed that if the system failed or had signs of deterioration that only 66% of homeowners would replace their existing boiler.

Reasons to replace your old boiler:


Switching from your old back boiler that is around 78% energy efficient to a new combi boiler which are 90% and above can save you up to £300 a year on your heating bill.


Modern boilers have been made with more advanced technology and safety features and have less chance of a gas leak compared to older boilers that were used 10-20 years ago.

Increase in property Value

It has been known that if you spend between £1,500 and £2,500 on a new boiler, it is one of the best home improvement investments you can make, that can increase your property value by up to £8,000 and this can also offer lower energy bills for rental property owners and tenants. 

Repair Costs

Many customers have wished that when a problem has occurred with their boiler and the expensive repair bills start coming in that they had just cut their losses and bought that new boiler instead of trying to bring the old one back to life, if your boiler is over 8 years old and has previously been repaired the chances of the number of repairs can increase, instead of racking up the repair bills of hundreds of pounds why not invest in a new boiler from Easy Boilers from £1795 Inc.

Increased kW Output

You may want to buy a boiler with a higher kW output, this can help your boiler service your heating and hot water needs more efficiently.

Better for the Environment

A higher efficiency boiler produces fewer carbon emissions and is also better for the environment as well as saving you money.

Do I need a system, regular or combi boiler?

So the next question is what type of boiler do i need, please see the guide below that will help you find out your boiler type if you aren’t sure what you need.

Combi Boiler

In the UK the most popular boiler type for households is the combi boiler, the combi boiler heats water directly from the mains supply which means it doesn’t heat the water you may or may not use and therefore doesn’t waste energy.   

You can identify the combi boiler as it is not connected to a hot water storage tank that is usually located in an airing cupboard or to a cold water storage tank usually located in the loft or attic.

System Boiler

System boilers are usually found in older houses that have one or more bathrooms, it has a hot water storage tank but no cold water storage tank; this is due to they cannot supply hot water to multiple bathrooms at the same time.

Regular Boiler 

A regular boiler can also be referred to as an open vent, traditional, standard or heat only boiler, like a system boiler they can supply hot water to multiple bathrooms but they have both a hot water cylinder that is usually located in the airing cupboard and a cold water storage tank located in the attic or loft and these tanks can take up alot of storage space.

Back Boiler (BBU)

Back boiler units are similar to regular boilers they have a hot water storage tank and a cold water storage tank but they are usually located behind an electric gas fire, these boilers are less efficient than the more modern boiler and are becoming less common to be found in houses as they are no longer installed.

What kW size boiler will I need?

When choosing your boiler you need to consider the kW (kilowatt) output this is the power of the boiler that will heat your home, the higher the kW of a boiler the more it can cope with the heating and hot water demands.

The factors to consider when choosing the kW of the boiler is the size of your home, how many baths you have and also how many radiators.

We have put together a guide located below that will help you choose the right kW boiler for your home.

24 – 27 kW Combi

Suitable for most apartments, flats, and smaller houses with up to 10 radiators and 1 bathroom.

28 – 34 kW Combi

How much does it cost to move my boiler?

Moving your boiler can depend on what type of boiler it is, where it is being moved to and how far it is being moved the cost of these factors can be anywhere between £200 and £600.

There could be additional costs for parts needed to move the boiler to the new location, if this is the case you will be quoted this when answering the survey questions.

If you are considering moving an older boiler to a new location it may be more beneficial to purchase a new boiler to move to your desired location, which can also save you up to £344 in energy bills by doing this and also getting you a great deal on your new boiler at the same time!

It can take between half a day to a day to install your new boiler in the same room or close to the old location, if you are moving your boiler from a different room such as kitchen, utility or garage to the loft then this can take a minimum of 1-2 days.
