Which is the Best Boiler Type for My Home?
Broadly, these water heating systems fall into 1 of 3 groups and would normally be referred to as Combination or “Combi” boilers, Condensing System boilers or Conventional (heat only) boilers with each type having its own merits and one type will be better suited to certain situations than others, which are explained below.
Your system will also receive the water supply in one of these ways:
Gravity Fed – you will likely have a cold water & an overflow tank, usually situated in the attic (loft space)
Direct Supply – sometimes called “High Pressure, unvented” sytems, typically a combi boiler will be like this.
