What’s the Difference between Combi and System Boilers?

Deciding on which boiler will be the right fit for your home can be a tough nut to crack.

It doesn’t have to be that way. For instance, knowing how a domestic boiler functions and the differences between a combi and system boiler can make all the difference when you are searching for a boiler for your home.

Differences between a Combi and System Boiler

Have you ever wondered what’s the difference between a combi and system boiler? The following are some of the things to keep in mind when it comes to choosing between a combi and system boiler.

Combi Boiler

A combi or combination boiler is a highly efficient heater and central heating boiler that comes in a single unit. This boiler is able to heat water directly from the mains whenever the tap is turned on. This takes away the need for storing water in a storage cylinder or a water tank. A combi boiler is also extremely cost effective mainly because it does not require the water to be pre-heated and stored. If you are looking to find the best combination boiler you will find it here.

System Boiler

A system boiler does require a water cylinder for storing the water which has been heated. The heating system is built into the system, hence the name system boiler. This makes it quick and easy to install the system boiler as compared to the traditional boilers. Furthermore, there is no need for a storage tank so they can be used in houses that have less space.

Size isn’t Everything

Contrary to popular belief, it is not necessary for the size of your home to determine the type of the boiler you require. While the size of your home is one of the factors that have to be considered when deciding on the type of boiler you choose, it is not the only factor. For instance, the amount of water your family uses also makes a major difference, along with when they are using it. This is the reason why the size of your home and the type of boiler that should be used does not always correspond. For instance, in a home with two showers you can use a combi boiler, but you will soon find that when running both showers at the same time, the water pressure is reduced significantly.

Keeping that in mind

If you do live in a big house that has large rooms, tall ceilings and more than two showers then it is advised to go for the system boiler. This is because the system boiler allows you to run as much hot water as you want without having an impact on the temperature of the water or your home. A system boiler is also your best option if you have a large family and are in need of more hot water as a result. On the flip side, a combi boiler is your best option for smaller families who don’t require hot running water as often.
