Aside from how complicated the work can be, three main steps are necessary for your new boiler installation.

Before a heating engineer can start with the installation of your new boiler, the old line will need to be removed.

For a more complicated boiler fitting or the relocation of a boiler, the heating engineer may need to remove old pipework and radiators, before installing the new boiler.

Second Step: The installation of your new boiler

After the removal of the old boiler and pipework, the heating engineer will start with the installation of your new boiler and its pipework. This step might be extremely quick, depending on how much work is needed and how complex the job ahead might be. It will not take a long time if you are getting a like-for-like boiler.

Third Step: New boiler product tour

Then he will show you the ropes. You will be instructed on how to use the controls, the features of your new boiler and how to set a schedule for your boiler to be turned off and on. Make sure to ask the heating engineers about anything that you might need help with. Taking notes might also help you in the long run to maintain your new heating system.

  • Perfect for areas with low water pressure from the mains
  • Suitable for homes with older heating systems that may not be able to tolerate high pressure
  • They take space since they need a cistern tank
  • A tank in the attic can freeze in winter and might cause many problems if it starts leaking

System boilers

What is needed for a boiler installation?

Installing a boiler is not something you should carry out yourself. It should be done by a fully qualified professional to make sure that it is installed safely and legally. So the first thing you will need is a Gas Safe registered heating engineer (OFTEC for oil boilers). This is all you will need to do to get a boiler fitted. Our heating engineer will often source the appropriate boiler and needed components themselves.

If you would rather source a boiler yourself to cut costs, it is possible to do so. However, you will still need to hire a Gas Safe registered heating engineer to install your boiler.

Some important factors to consider for a boiler replacement:

As has been noted, a new boiler replacement might not be that cheap. So it’s important to consider some key factors before making your final decision.

The size of boiler you need (kW output)

When we talk about boiler size, we do not mean its dimensions, but rather its power output. The unit of measurement, used for boilers, is the kilowatt (kW).

To clarify, the higher the output of your boiler, the more powerful it will be. Nonetheless, it’s never a great idea to get the boiler with the highest output rating. A too high output rating would increase your energy bills. And a too low output rating will not meet your demand.

Through counting the number of bathrooms and radiators in your home, you can find the most appropriate output rating for you. This information can also help you have an idea of the level of demand for domestic hot water and central heating.

With this purpose in mind, we advise you to get a quote from a Gas Safe registered engineer. If you have a brand in mind, then you should check their website and guidelines. A lot of manufacturers, nowadays, offer advice on their websites.

To point out, small homes with one bathroom and little or no space for a cylinder should consider getting a combi boiler.

Location of the new boiler:

It will cost you less if you install your new boiler in the same location as the old. Moreover, it will make the job more straightforward.

On the other hand, you can move your new boiler to a different location if you want to. But it goes without saying that you will have to pay more. 

The process of moving your boiler requires more work and materials. You will need a new flue installed and new pipework re-routing through your home. This process can be very messy though. 

Energy efficiency:

If you want to reduce your carbon footprint, save some money and keep your house warm and fuzzy, then it’s important to get an energy-efficient boiler. 

At Let’s Heat, we offer modern A-rated boilers that can be bought with a smart thermostat in order to reduce energy wastage.

You can save about £340 and 1,500kg of carbon dioxide a year if you replace your old boiler with an A-rated boiler and set of heating controls according to the Energy Saving Trust.

Best Installation Time:

Some replacement boiler installation takes longer than other. Some are just more complicated than others.

For instance, replacing your combi boiler with another combi boiler might take around 1 day. 

Oh the other hand, converting, for example, a combi boiler to a system boiler is probably going to take 2 days.

What are the regulations of boiler installation?

There are several building regulations that should be followed when installing a boiler. These regulations include finding an acceptable locations for the boiler to be placed, where the flue can and can’t be located, whether the right size of gas pipe has been installed, and whether the boiler has a high efficiency rating. And the list goes on.

There are so many building regulations to follow when installing a boiler. That is why it is best to let an accredited professional do about. You will know that all of the proper regulations have been followed once you get a Building Regulations Compliance certificate from the heating engineer.

The best way to make sure that your boiler installation follows all of the necessary building regulations is by using a Gas Safe registered heating engineer.

Energy regulations:

Over the last few years, the UK has passed some guidelines for boiler installation and energy efficiency:

  • Gas boilers should have at least a 92% ErP efficiency regardless of boiler type.
  • A Combi boiler installation should have one energy-saving feature.
  • You should have functioning time and temperature controls.

How long does it take to install a boiler?

Installing a boiler can take between 1 to 3 days to complete, depending on the complexity of the installation. In short, the more complicated the installation is, the longer it can take. Longer installation can also increase the cost of labour.  Quick installations might take as little as 4 to 6 hours to complete, especially for like-for-like boiler installation jobs.
