Your boiler keeps you and your family warm, clean and healthy. Without exaggeration, the boiler is the heart of your home. So when the time comes to replace your boiler or central heating system, it’s not a task to be taken lightly or a time to cut corners.

Whether you are looking for a like for like replacement or a complete system overhaul, it’s a good idea to do your own research. Sticking with the existing heating system and simply upgrading the boiler may be all that is needed, but it could be worth considering a change.

New Boiler Deals: What Do You Need to Know

What can you afford to spend?

Get a budget sorted early on so you are not persuaded to overspend. There are installers that offer finance agreements to spread the cost if this is an issue so it’s worth checking if this is an option.

How much water do you need?

This will be directly linked to the size of your home and how many bathrooms you have, but the installer should also ask you questions about your lifestyle. With this information they can work out how much hot water you will need and what system is best for you, so be prepared with some answers.

Where will the boiler live?

If you want to put the new boiler in the same position as the old, you need to consider that modern condensing boilers produce steam which needs to be carried to the outside via a pipe (called a flue). Depending on where your boiler is, steam clouds might be an irritation. There may be a higher cost involved in relocating the boiler so it is worth asking if there are any other options like adding extra piping or a pump so the steam can escape elsewhere.

What does the future hold?

There’s no getting away from the fact that this is a significant amount of money to spend and not an expense you’ll want to repeat for a while. If you’re planning a refurbishment, extension or loft conversion then this will impact your choice as some boilers require space for tanks and cylinders. Is there a chance you might want to embrace renewable heating technology at some point? If so your boiler may need to be compatible to avoid another installation down the line.

Choosing a New Boiler Deal

What type?

There’s no one size fits all answer to this question which is why you need to get the opinion of at least 3 professionals. The type of boiler and heating system you choose should suit your home, family and lifestyle and is usually dictated by the property you live in. For example, a small 1-2 bedroom house or flat usually needs an all-in-one Combi that heats water on demand, while bigger homes with multiple bathrooms and radiators will have a higher demand that is best met with either a System or a Regular/Conventional boiler.

What brand?

Not all boilers are created equal and that is reflected in the range of price tags on the market. It can be tempting to opt for the cheapest, but they are the cheapest for a reason. Lower quality materials and parts will not deliver the same efficiency and will not last as long meaning more expense in the long term. For example, heat exchangers can be made of either stainless steel or aluminium. Aluminium is cheaper to manufacture but it will corrode over time while stainless steel will not. If you can afford to spend more, it really is worth the investment.

What size?

The size of a boiler, also known as output, is measured in kW. In basic terms the higher the number the better the supply of hot water, but this doesn’t mean everyone should be buying the highest output available. Your boiler’s output should suit the size of your home, number of bathrooms and number of radiators. This is something that installers will be able to advise you on but some less reputable installers may try to sell bigger boilers than you need to maximise profit. For example, when purchasing a Combi boiler, here is a rough guide:

24-27kW = small house (1-2 bedroom) or flat, up to 10 radiators, 1 bathroom
28-34kW = medium house (3-4 bedroom), up to 15 radiators, 1-2 bathrooms
35kW-42kW = large house (4 or more bedrooms), up to 20 radiators, 2 or more bathrooms*

*Combi boilers are not generally recommended for larger homes with 2 or more bathrooms as they only provide a single flow of water that weakens when split between outlets.

It’s also worth noting that an electric shower doesn’t take its water supply from the boiler so doesn’t need to be included in the calculation.

Choosing an Installer

It’s usually recommended that you compare 3 quotes from different installers. This will give you a good price range and enable you to compare their expertise and advice. A good idea is to get quotes from both local and national installers as local companies may offer lower costs but national suppliers provide better aftercare services.

Boilers are complicated machines and can be dangerous if installed incorrectly. To make sure you’re dealing with the real deal, there are a few checks you can make:

  • Make sure they are Gas Safe registered (OFTEC registered for oil boilers). You can check this yourself online and ask to see their ID card when they visit
  • In addition to confirming they are registered, the ID card will specify what kind of work they are qualified to carry out
  • Ask them to provide references from previous customers. If they can’t, ask why not?
  • Are they accredited or specially trained by any manufacturers? If they are then you may receive a longer manufacturer warranty on your boiler.

Check out our list of questions to ask boiler installers BEFORE you commit to a quote in the free Getting the Best Deal on Your New Boiler PDF here.

Compare Boiler Prices

Costs will vary from installer to installer which is why we advise getting multiple quotes with detailed breakdowns. Only then can you compare like for like.

A quote will usually include:

  • Cost of boiler
  • Labour costs
  • Any additional elements, materials, e.g. pipes, radiators, Powerflush, TRVs, magnetic filter, temperature control system, pumps
  • Ongoing maintenance/servicing packages.

Many installers are able to offer finance options so you can spread the cost via monthly payments and these can often include annual servicing.

Planning for the future

A good deal will not only include the initial work but should also include some form of after sales service.

After Sales Service

Some installers are perfectly competent to advise and install but not so keen (or qualified) to diagnose and repair a breakdown. Will they be at the other end of the phone if something goes wrong?

Servicing

To keep any new boiler running efficiently and safely, to increase its lifespan and keep the manufacturer’s warranty valid, the boiler needs to be serviced by an engineer every year This ensures potential problems are nipped in the bud before they cause other problems or damage the system over time.

Warranty

If the quote you’ve received includes a charge for a boiler warranty you need to check what the manufacturer offers as standard. Some boiler manufacturers offer warranties which include both the replacement parts and the provision of a qualified engineer out to carry out the work, so taking out another warranty with the installer may be unnecessary. It’s also worth knowing that some manufacturers will increase the length of warranty included if the boiler is installed by an engineer who has been specially trained to work with their models, so check your installer’s credentials.

Boiler Cover

It is possible to take out boiler insurance but if you are already paying for a servicing plan and the boiler is covered by a warranty, it may well be redundant.

Think About Renewable Heating

You may have assumed that introducing renewable technology into your heating system would be too expensive or ineffective, but more and more manufacturers are now offering systems that work seamlessly with solar thermal panels or heat pumps. Prices are more competitive than ever and could significantly reduce your heating bills, so it’s worth asking your installer about it your options.
