There are three primary types of residential boilers available on the market today: , system , and regular (conventional) boilers . Most modern units across all three categories utilize condensing technology to maximize energy efficiency. Main Types of Residential Boilers
: Also known as "traditional" or "heat-only" boilers, these systems require both a hot water cylinder and a cold water storage tank (usually located in the attic). Types Of Residential Boilers Available In Marke...
: These require a separate cylinder for storing hot water, but the major heating and hot water components are built into the boiler itself, making installation cleaner. There are three primary types of residential boilers
: Common in rural areas where the main gas grid doesn't reach. Summary Comparison Table Boiler Type Storage Tanks Needed Best Home Size Main Benefit Combi Small / Medium Space-saving & hot water on demand System Hot water cylinder Supports multiple taps at once Regular Hot & Cold tanks Large / Older Ideal for low-pressure pipework : These require a separate cylinder for storing
: Older homes with traditional heating systems that may not handle the high water pressure of a combi or system boiler. Modern Efficiency & Fuel Sources
: This is not a "type" like the ones above, but rather a feature. Modern boilers are required to be condensing , meaning they capture and reuse heat that would otherwise escape through the flue, significantly lowering energy bills. Fuel Types : Gas : The most common and typically the cheapest to run.
