System Boiler – Fireplaces & Heaters
A system boiler provides hot water for radiators and either a traditional copper hot water cylinder or an unvented stainless steel pressurised cylinder. It differs from a conventional boiler as most of the extra components found on a heating system are incorporated into the boiler case such as a pump, and expansion vessel.
All new Central Heating Boilers are of the ‘Condensing’ type to achieve the minimum efficiency standards.
