What’s the difference between the available boiler types?
The most common boiler type in UK households is a combi boiler. As the name suggests, a combi boiler contains both a water heater and central heating system, so that you don’t need a separate water tank. They’re generally cheaper and easier to install.
A system boiler needs an external tank to store the hot water but the heating is carried out by the boiler.
A standard boiler needs a hot and a cold water tank. They’re usually found in older homes with pre-existing heating and water storage systems.
How do I choose between brands?
It could seem overwhelming at first as there are lots of brands out there. Each brand has its own advantages.
Consider your budget, as different brands will sit in different price ranges.
Look to your fellow consumers, by researching the brands and their reviews on sites such as ‘Which?’.
The decision to buy a new boiler should be driven by facts, figures and unbiased reviews over personal preference, as a lot of people make decisions based on pride, historical reputation and looks, which are not backed up by facts.
How often will my boiler need replacing?
On average, a boiler should last between 10-15 years. It may last longer if you take good care of it and have it checked regularly.
When repairs begin to cost too much or mount up, it’s time to consider a replacement. A good engineer should be able to help you decide when the time is right and point you in the direction of the best type of replacement for your home.
Replacing at this time will ultimately save you money in the long run.
What if it develops a fault?
When an issue occurs with your boiler, it’s not always simple to understand whether it’s serious or not. The best option is always to consult an expert engineer. Most often, it’s a common problem with a known fix however, on the rare occasion it’s something more serious, it may be unsafe to continue using it. An expert engineer will easily be able to assess the situation, giving you peace of mind.
To service, or not to service?
It may seem unnecessary and inconvenient to have your boiler serviced when there doesn’t appear to be anything wrong with it, but having it serviced once a year will help to prolong its life. A yearly service will also prevent unforeseen issues with the boiler and make sure it is running as efficiently as possible.
Is my boiler economical?
You can get a good idea of whether or not a boiler is economical by looking at the ErP, SEDBUK 2009, and SEDBUK 2005 ratings. A well rated boiler will run very efficiently, whereas a poorly rated boiler will run up more costs and may well cost you more than a replacement would. An old boiler will never be as efficient as a newer model and nearly all modern boilers are A rated, which means they’re highly efficient.
