Combi Boiler System
A combi boiler system does not require attic tanks or hot water cylinders.
It produces central heating and hot water within the boiler unit itself.
What do we mean by a Combi Boiler System?
This may be confusing for some people, because essentially there are three types of boiler configurations:
- Open Vent/Conventional/Regular Boiler (Requires tanks in attic for storing cold water, and cylinders to store hot water)
- Sealed System Boiler (Requires a cylinder to store hot water. Doesn’t require attic tanks)
- Combination (or Combi) Boiler (Does not require any additional tanks or cylinders)
Not to be confused with a Sealed System boiler, we believe why some people call it a “combi boiler system” is simply to illustrate that a combi boiler does a lot within the same compact unit.
