Farmhouse oil boiler replacement across the Mendips
Mendip farmhouses tend to have long oil-line runs, generous but under-insulated cylinders, and boilers half-hidden in a boot-room or outbuilding. Replacing sensibly means rethinking the boiler location as much as the boiler itself.
For: Mendip farmhouse owners on oil

Why external usually wins
Moving to an external Grant Vortex frees up a room, kills the combustion-air arguments, and turns the flue into a non-issue. On a farmhouse with an old oil-line, external boilers also let us shorten the run and add a modern Tigerloop for de-aeration.
What the farmhouse replacement covers
- Boiler-location review — internal, external, boiler-house
- Oil-line assessment and Tigerloop where distance demands
- Tank clearances checked (bunded, fire-rated boundary)
- System flush, magnetic filter and re-balancing
- OFTEC CD/11 completion certificate and Building Notice
Frequently asked
- Can you replace a boiler in an outbuilding?
- Yes — provided it has adequate ventilation. Often the honest answer is to move to an external Vortex and free up the outbuilding entirely.
- What about heating a barn extension too?
- We size for whole-house heat loss including any extension. Sometimes a second zone valve and a rebalancing sorts it; sometimes an upsize is needed.
- Do you handle the tank as part of the same job?
- Yes — if the tank is out of clearance or past its life, we quote both in one line so nothing lands as an unexpected extra.
Book the farmhouse survey
We'll walk the site, measure oil-line lengths, look at flue options, and quote a replacement that solves the pre-existing problems rather than inheriting them.
