Boilers are a staple of every home, and yet many people know very little about these devices. Below, our team of experts have put together a helpful FAQ, with everything you need to know about boilers, so you can make informed decisions when it comes to understanding, purchasing, replacing, or upgrading your boiler.
Which boiler is best for me?
There are three main types of boilers: Combination (combi), Condensing, and System.
Combination or combi boilers are the most popular model of domestic boiler in the UK. They provide instant heat and hot water without needing the space for a large hot water cylinder or supply tank in the airing cupboard. However, the water pressure may be reduced if more than one water outlet is used at any one time.
Condensing boilers are far more efficient than older models. They convert the water vapour condensation into heat. As highly efficient devices, not only are they cheaper to run, but they also reduce carbon emissions. However, hot water is not available as instantly as with a combination boiler, as the water needs to heat up first.
System boilers, also known as ‘sealed systems’ are like conventional boilers, as they have a hot water tank, but they do not have a supply tank. They are filled directly from the cold feed. These boilers are great if you need hot water available from multiple taps at the same time. However, instant hot water is not available, and the hot water cylinder takes up space, so they may not be best for smaller houses.
What boiler size do I need?
Choosing the correct boiler for your home depends on many factors, including how much space you have. For those who are short on space, a combination (combi) boiler is better as it doesn’t require a hot water cylinder. For those in larger spaces, a conventional boiler may be better for efficiency.
How often do boilers need servicing?
To ensure that your boiler is running safely and efficiently, it should be serviced once a year. Not having your boiler serviced could lead to faults, higher energy bills and potential breakdowns. Our BoilerCare cover includes a FREE annual boiler service and safety check as well as 24/7 call outs in case of breakdowns.
Why check your boiler?
A poorly maintained appliance runs the risk of leaking carbon monoxide – known as the silent killer. All boilers should be checked by a gas safe registered engineer. If you take out one of our BoilerCare plans, your boiler will be serviced annually by one of our heating engineers.
Why is my boiler leaking water?
A boiler that’s leaking water needs the urgent attention of a qualified heating technician.
High pressure, loose joints, corroded pipes, or simple old age are all possible causes of a leaking boiler. If your boiler was only recently installed, it could be down to faulty installation.
With our 24 hour BoilerCare Cover, if your boiler is leaking water, one of our certified engineers will be on hand to help. Our plans offer 24/7 emergency callouts, with 98% of calls being responded to on the same day.
Are boilers covered on home insurance?
In most cases, standard home insurance will not cover the cost of fixing or replacing a boiler. Don’t get caught out with unexpected repair bills. Be prepared with our boiler cover, starting at just £10 a month, with the price fixed for the first 2 years.
