Oil-fired boilers and systems

Worcester’s oil-fired boilers are available in combi, regular and system models. We offer high efficiency Greenstar condensing models, which operate to at least 90% efficiency (compared with many older boilers that can be as little as 50% efficient). All of the regular and system boilers are also compatible with Worcester Greenskies solar panels.

Free 5 year oil-fired boiler warranty. Find out more…
