Trianco oil boilers: a UK manufacturer with rural heritage
Trianco is a UK manufacturer focused specifically on oil and biomass heating for off-grid rural properties, giving it a similarly deep specialism to Grant in that particular corner of the market. It's less prominent in general marketing but well regarded among engineers who work regularly with oil systems.
Understanding a Trianco oil boiler before you spend money
Trianco's product range spans both floor-standing and other formats aimed at the same off-grid rural market Grant and Worcester's oil ranges serve, so the practical comparison for a homeowner often comes down to specific output, siting requirements and confirmed local parts support rather than one brand being categorically superior. As a UK manufacturer, parts distribution for common wear items is generally reasonable through OFTEC supply channels.
