System boilers are great for homes with a larger output of hot water, such as homes with 3+ bedrooms.
This type of boiler has the water supply from the mains and supplied via a large tank or cylinder so they have water available on demand.
On the other hand, because they store water in a cylinder, (which needs alot of energy) they will sometimes leave you waiting for it to refill before you can access hot water.
A system boiler also requires the hot water tank to be stored somewhere in the household, so it takes up more space.
They are more expensive than combi boilers to buy initially however they have a better reliability. Combi boilers are also cheaper to install.
Make sure your boiler has a stainless steel heat exchanger! Why? let’s discuss….
Boilers demand the most energy efficient and reliable components. A key component in choosing the right system is the heat exchanger within the boiler.
Heat exchangers are one of the most likely failure concerns in most boilers.
This is because maintenance costs, durability and product lifetime should all be considered when buying a boiler.
Stainless steal exchangers provide a high resistance to corrosion and increase the life of your boiler.
Due to these key factors this provides long term value for money and requires less downtime in your house hold due to boiler maintenance.
They are also self cleaning and no not require inhibitors for the water to be able to drink.
Our recommendation is the Viessmann boilers range as they feature stainless steel heat exchangers.

Combi Boiler vs. System Boiler – Which One is Best for Your UK Home?
This completely depends on the type and size of home that the boiler is to be installed.
We would recommend a combi boiler for homes that have 1-2 bathrooms or showers however if a home has multiple bathrooms and showers then a system boiler is a better solution to provide enough hot water.
System boilers actually store hot water in a cylinder, making more available when and if you need it.
Combi boilers on the other hand heat hot water on demand which means if there are 3-4 showers running at the same time in a home then your combi will struggle to meet the demand.
This will find you the right boiler for your home, at the perfect size and performance and even a fixed price that you can purchase online by card or get an instant finance decision.
