Boilers unfortunately don’t last forever. Old boilers have a habit of breaking down when you’re least expecting it, leaving you with the unwelcomed hassle and expense of replacing them without warning.
Can you remember when you last replaced your boiler? For many it was way before they even moved in so they often have no idea how old it is or when it’s due to be replaced until it’s too late.
We’ve put together a quick guide to replacing your boiler to help you make the best decision.
Common types of boiler
These are the most common types of boiler installed in the UK. You may choose to stick with what you know and get the same type of boiler. This means it’ll probably be easier to install but you may be missing out on features that other types can offer.
Combi-boilers are the most common boilers for new installations in the UK. They can produce both hot water and central heating quickly, making them ideal for busy people. The boilers are often compact and don’t need a tank installed so can save space in even the smallest of homes.
If you live in an old home you may have a conventional boiler. They work by supplying heat to radiators and also heat up a tank for hot water. The main downside is that hot water can run out and you’ll have to wait for it to reheat.
The upside is that water pressure isn’t affected by using multiple taps in the house so it may be better for bigger homes and families.
A system boiler is similar to a conventional boiler in that it uses a tank to heat up water. However, it differs from a conventional boiler as most of the components are built into the boiler itself. This makes installation quick and easy.
Hot water is actively pumped around the radiators and the hot water tank rather than the convection method that conventional boilers use. This means that they’re often more responsive and economical. The downside is that hot water won’t be instant and will take time to heat up.
Most new boilers have been condensing for the past decade or so, whether they’re combi boilers, conventional or system boilers. They work by retaining heat ordinarily lost in the form of hot gasses released from heating up the system.
This means that they’re more efficient and will require less heat and gas from your boiler, saving you money.
However, they do require an external drain that may need re-positioning. You’ll also need a condensate pump and drainage pipe which can become a problem if it freezes over so you’ll likely need some form of insulation.
How big does your boiler need to be?
Boilers come in different sizes depending on whether they’ll be in a big house or just a flat. This is something a qualified gas engineer will be able to help you with by looking at both the size of the property and the space available to install a boiler.
It will also depend on the quality of insulation as this will affect how much heat is likely to be lost through windows, walls and doors. If your home loses a lot of heat, it’ll need a more powerful boiler to heat rooms sufficiently. Looking into insulation will help to reduce your heating bill and the size of boiler you require.
For flats and small houses, a typical sized combi-boiler is around 24kW-28kW. For a 3 bed house, it can start at around 28kW onwards. This will depend on the size of the house and how many bathrooms and radiators there are. Large properties with multiple bathrooms will need boilers at around 33kW-42kW.
Getting your boiler installed
Once you’ve made your choice your new boiler will be fitted by a boiler engineer who will be able to take you through how to use it. They’ll also be able to tell you how this boiler differs from your previous if you’ve made the switch to a different type.
Once your new boiler is installed you can enjoy saving money with a more energy efficient system that will last years to come.
