Combi, system, and regular boilers
Before you choose a boiler brand, you need to choose the type of boiler that suits your lifestyle. All new boilers that are fitted in the UK after 1st April 2005 must be condensing models.
Condensing boilers are designed to minimise the heat that is lost up the flue, making them much safer, efficient, and better for the environment.
A professional boiler installer will be able to help you decide which system will be best for you.
But what are the choices?
A combi or ’combination’ boiler takes its name from the fact it is a hot water and central heating system together in one unit. Water is heated via the mains so there is no need for water tanks.
System and regular boilers
A system boiler takes water directly from the water supply, which is then heated using your homes energy source. The hot water is stored in a tank until it is needed in the home. It is also used to provide heat for your central heating system.

Finding and comparing boiler installers
As the homeowner, it is your responsibility to arrange for the boiler to be installed once it has been purchased from the manufacturer.
The manufacturer may give you a list of trusted installers or will suggest one that they work closely with.
Should I choose a local or national installer?
There are a variety of companies to choose from when it comes to installation of your boiler. You may feel more comfortable choosing a well-known national company, or you could choose a local installer that may offer a more personalised service.
You are likely to get a longer warranty with a national brand, but local installers may be cheaper and will be able to respond to any problems quickly.
Gas Safe engineer
Whoever you choose to install your boiler, they must be gas safe registered. It is particularly important to check their qualifications as this means they will have the knowledge and experience to complete the installation safely.
Using an engineer that is not gas safe registered will also invalidate your warranty.
Guarantees and warranties
Guarantees and warranties are technically very similar. You will have different warranties and guarantees for the parts and the installation, so ensure you check the T’s and C’s when making your purchase.
- Check what the manufacturer is offering and look for a minimum of 10 years.
- Warranties and guarantees may come with certain conditions such as annual servicing.
- A warranty is more like an insurance policy for the reliability of the parts.
- A guarantee is a contract that means the manufacturer will sort any repairs or replacements within a given time period.
- A guarantee gives you peace of mind that your boiler will be repaired if there are any issues.
