The AA has produced a straightforward boiler guide to help householders better understand their boiler, hot water and central heating system. Covering everything from boiler types and controls to how to effectively use the system, the guide is designed to help householders save energy by using their system properly and encourage them to get it regularly checked and serviced.
The guide explains how combi, sealed systems and open vent systems work using simple diagrams. Other advice addresses boiler controls, temperature timings, room thermostats and the pilot light. There is also a section on how to achieve cost-effective heating.
