A combi boiler, or combination boiler is a single unit appliance that produces heating and hot water on demand when you need it. Combi boilers are the UK’s most popular choice of boiler. I am going to be talking about the pro’s & con’s of having a combi boiler installed in your home and exactly what you need to know when thinking of purchasing a new combi boiler.
Combi Boilers are more economical as you only heat the hot water that you actually require
As a combi boiler runs off your cold water main then you get more powerful hot water, as long as your cold water main is adequate
You get an unlimited amount of hot water. As long as there is a demand i.e a tap is open, then the combi boiler will keep producing hot water
You do not have any tanks or cylinders with a combi boiler so they are great at saving you space
As all the components are inside a combi boiler, when having a new one fitted will mean everything within the boiler will be covered by the manufacturer’s warranty as oppose to external pumps, zone valves, vessels etc
A combi boiler is usually quicker to install as they have less boiler parts than other heating systems
Central heating systems are usually cleaner with a combi boiler fitted as it is a sealed system with no storage tank where rust and debris can build up
No back up hot water, as a combi boiler is a single unit appliance it has no cylinder (stored hot water) with an immersion so if your combi boiler breaks down you will have no heating or hot water (un less you have an electric shower fitted)
Limited hot water use, as a combi boiler runs off your cold main you will not be able to operate more than one tap at a time without it effecting the other outlet, e.g if you are in the shower and someone runs a tap downstairs it will effect the flow and temperature of the shower
Dependence on Cold Water Main Supply, because a combi boiler runs off your cold water main you need to have a good flow rate coming in to your property to achieve the combi boilers hot water outlet
So if your house has more than one bathroom and you often use more than one tap/outlet at the same time then you may need some stored water instead of a combi boiler as this will give you enough hot water when multiple outlets are being used.
If you have one bathroom or even an en-suite as well with an electric shower then a combi boiler will be more than adequate. Just remember you CANNOT run more than one tap with a combi boiler without effecting another taps flow rate.

Our recent boiler conversion was entrusted to Platinum. I was quite nervous about this job given both the complexity and the fact we are in the depths of Winter. I needn't have worried. Matt's professionalism put me at ease and made sure we were without heating for as little time as possible. All carpet surfaces were covered before any work was done and everything was left spick and span at the end of the job. Highly recommended.
I have employed Matt to carry out all of my plumbing work to the past two house renovations that I have done. Most recently he fitted a new bathroom, boiler, kitchen and radiators throughout my house. I found Matts work to be of an excellent standard. He was professional, tidy and always showed up when he said he would.I have also recommended Matt to three of my friends who he has also fitted boilers for. Would highly recommend.
Matt has always provided a fantastic service for the properties we rent out. He fitted a Worcester Bosch boiler at very short notice for one of our tenants who had no heating or hot water very close to christmas.
We use Matt now for all our Plumbing problems, he fitted our new boiler and has done all the services on it too. He is always friendly, efficient and provides a great service. Matt is always reliable, and comes when he says he is going to, unlike others we have used in the past. We have had terrible experiences in the past with other companies, so would choose Matt every time!!! Highly recommend!
Just had a new boiler and pipe work redone by Matt from Platinum and he’s done a fantastic job, He kept his whole work area tidy whilst working and went round the whole house checking the existing radiators were working properly and all the taps were giving us hot water, Great job ...
Have used Matt from Platium Boiler Installations twice now and he’s already looking at more work for me. Great service and he’s prices are competitive. Very knowledgeable, and takes time to explain the different options.I love the extra back up that comes from using a Worcester Bosch approved installer and the reviews they have are a credit to the standard this company operates to.Would highly recommend Platinum
