Grant Vortex oil boiler installation across rural Somerset
Grant's Vortex range is the workhorse of rural Somerset — quiet, ErP-A rated, and available as internal, external, boiler-house or utility versions. As OFTEC-registered installers we can pick the right variant for your tank distance and flue route before quoting.
Why the Vortex suits Somerset properties
Stone farmhouses and cottages around Mendip and Chew Valley often have long oil-line runs, poor combustion-air paths, or awkward flueing near listed structures. The Vortex external, in particular, sidesteps most of those issues by moving the boiler outside entirely.
What a Grant Vortex install includes
- Site survey with OFTEC combustion-air and flue checks
- Fire-valve on the oil supply and Tigerloop de-aerator where needed
- Old-boiler decommission, oil-line purge and system flush
- Grant guarantee registered (up to 10 years with annual service)
- OFTEC CD/11 completion certificate — no council paperwork for you
Blue-flame vs yellow-flame burners
Blue-flame Vortex models run cleaner, quieter and produce less soot on the heat exchanger. On some rural sites with older kerosene deliveries, we still recommend yellow-flame for its tolerance of variable fuel quality — the survey decides.
Frequently asked
- Can I keep my old oil tank?
- If it passes an OFTEC inspection (no bulging, valid bund, correct clearances) then yes. If it's out of clearance from a boundary or building, we'll price a replacement alongside the boiler.
- How long does the swap take?
- A like-for-like Vortex swap is normally a single day. A first-time internal-to-external move is usually two days because of the flue and oil-line reroute.
- Do you cover Wells and Shepton Mallet?
- Yes — those are core patch. Everything inside a roughly 20-mile radius of Radstock is same-week response.
