Boilers are expensive. Make sure you know what you’re looking for before making your decision.
Most people don’t looking forward to buying a boiler. It’s expensive and complicated, but it needs to be done. Choosing the right boiler can save you money in the long run, so here are a few things to think about before you buy.
Typical installations can cost between £3,000 and £5,000. It’s not something you can get cheaply, so don’t expect to get a deal below this range.
The more reliable (and probably expensive) your boiler is, the less money you’ll end up spending on maintenance. This is something to keep in mind if you’re reluctant to fork out for a better product.
2. The cost of fees
If your boiler is in working condition then it’s still important to get it regularly serviced and maintained. This helps future-proof your boiler from problems, while will support your insurance claim should things go wrong.
Boiler repairs cost anything from £80 to £300. As mentioned above, it’s sometimes worth going for a more expensive deal to guard against future outlays.
3. Which type of boiler to go for
There are three types of boiler:
A combination boiler. This is the most popular type. It heats water directly from the mains, allowing a constant flow of hot water. This way you don’t need a storage tank.
A heat-only boiler. Also known as a conventional boiler, this will store hot water in a tank for you to use later.
A system boiler. Similar to a heat-only boiler but often takes up less room in your home.
The good news is that you’ll likely save loads of money if you’re buying a new boiler. Chances are your old boiler was inefficient, with modern boilers capable of shaving hundreds off your average energy bills.
5. You need to get the right size boiler
The size a boiler needs to be varies from property to property. For example the number of people living at the property or the number of bathrooms can have an impact on getting the right sized boiler. Here’s a list of some common boiler sizes.
24-25kw – suits flats or houses with 2-3 bedrooms, with around 10 radiators
28-30kw – suits 3-4 bedroom house with around 15 radiators
33-35kw – suits large houses with around 20 radiators
40kw + – suits larger properties with more than 20 radiators
If you’re not sure what size you’ll need, it’s best to ask your heating engineer. But remember, they’re often incentivised to sell and install particular brands of boiler!
6. Choosing the right brand
You might be tempted by a good deal on a boiler from a lesser known brand. If you’re confident and trust your research, then by all means go for it. The last thing you want, however, is your heating to go out in the middle of winter. Here’s a list of some of the most popular brands as an indication of who to look out for.
