A Guide to Buying a New Boiler

It may well be time for a new boiler, but you should never jump in wallet first and buy the first thing that is offered to you. There is a lot to consider, and having a bit of background knowledge could really help. So read this new boiler guide first, then you will be in a much better position when you buy a new boiler!

Boiler Types

Whilst there are a small number of exceptions to the rule, generally all new and replacement boilers must be high efficiency condensing boilers. Despite a slightly higher initial outlay, these new boilers do have their benefits. Better for the environment, they can reduce Carbon Dioxide emissions by up to 30%; even better for your wallet, they can reduce heating bills by some 40%.

There are three types of condensing boilers: conventional or traditional; system or combi. When your boiler engineer carries out their inspection they will advise you on the best choice for your property but as a rule, generally combi boilers suit flats and apartments and traditional or system boilers are chosen for larger properties with more space.

The Inspection

It is best to be fully prepared for the engineer’s inspection visit as you will be asked lots of questions. Answering these questions as fully and accurately as possible will mean that the boiler selected will be the very best choice for your property and lifestyle. Here are some questions you might be asked:

1.     What is your budget?

Decide how much you want to spend and stick to it. You may want to consider finance options; look into these before the engineer’s visit.

2.     Where will the new boiler be situated?

Note that the new condensing boilers emit steam because the exhaust gases are of a lower temperature. This could mean that you may want to reconsider the location of your flue as it could prove a nuisance in its present location.

3.     What level of demand will there be on the boiler?

Think about how many people need to use hot water at the same time, for example a larger family all getting ready for work or school at the same time in the morning using more than one shower at any one time. The engineer will need to make sure that the boiler is of a specification that can cope with the demand that will be placed on it.

4.     Do you have any plans to alter your property in the future?

If so you must let the engineer know because they could have an effect on the choice of boiler. For example, if you are planning a loft conversion then your engineer may steer away from suggesting a conventional boiler as their expansion tanks require space in the loft. If you are thinking about extending your property then it will of course be necessary to take the additional space, its planned use and potential increase in demand into consideration.

Think about Alternatives

A solar heating system can provide a reasonable share of domestic hot water energy. Solar heating is often considered expensive but if it is combined with a new boiler installation then the costs can be cut substantially and the long-term savings on fuel bills, as well as the knowledge that you are contributing to the welfare of the planet, suddenly become a realistic option.

What you should ask the Engineer

You should never be afraid to ask your engineer as many questions as you need to give yourself peace of mind. Here are some examples to get you started:

• Are they CORGI registered?




• Are they fully insured and is their work guaranteed?




• Can they provide testimonials from satisfied customers?




• Are they a well established business?




• Do they offer a dependable after sales service?




• Do they offer a reliable service and maintenance programme?




• Will they give you a full written quotation including parts, labour and the precise details of the boiler (make, capacity and efficiency) to be supplied?

A boiler is a large purchase and an investment for the future yet many people fail to grant it the consideration they would when buying, for example, a new car.

If you are in the market for a new boiler then take your time, study this guide and never be afraid to ask as many questions of your chosen engineer as you like. A boiler has an important job to do – so make sure your decisions are made wisely so that it carries on doing its job for years to come.
