What the buildings in Cranmore change about the job
Stone cottages and farmhouses around here were mostly built long before central heating existed, so pipework and boiler locations have usually been retrofitted at some point, sometimes more than once. Thick stone walls, uneven floor levels and low ceilings can all affect where a boiler or cylinder can practically go, and older stonework doesn't always take fixings the way modern block or brick does. We work around those constraints on site rather than assuming a straightforward install. Terrain is level, which matters for condensate runs and tank siting. Cranmore is roughly 8 miles from our Radstock base via the A361. Typical property stock here: stone cottages. A meaningful share of properties around Cranmore are off the gas grid, so oil boiler installs and tank swaps make up a fair part of what we do locally. Repair calls in Cranmore usually get a same-week visit, with most common faults fixed on the first attempt.

Straight answers for Cranmore homeowners
- Who actually carries out the work?
- A Gas Safe and, where relevant, OFTEC registered engineer from our own small team carries out the job — we don't sub the install out to a third party after quoting. You deal with the same people from survey through to commissioning and any aftercare calls.
- Could we switch from oil to mains gas if it's nearby?
- It depends entirely on whether a gas main actually runs past the property — some parts of the Somerset patch we cover have gas on one side of the road and none on the other. We can check with the network on request; if it's there, a conversion is a bigger job than a swap but often worthwhile long-term.
- Stone cottages seem to lose heat fast — does that change what boiler we need?
- Solid stone walls and older windows do increase heat loss compared to cavity-wall construction, so we size the boiler and radiators around a proper heat loss calculation for the property rather than just matching what's there already. Getting this right matters more in a cottage than a modern house, where an undersized system will never quite keep up.
- What support do I get after the install is finished?
- Once commissioning's complete we talk you through the controls, leave the paperwork, and register the manufacturer warranty on your behalf. If anything doesn't feel right in the first few weeks — a fault code, an odd noise, a control setting you're unsure of — call us during office hours and we'll talk it through or come back out.
- Is it worth upgrading the heating controls when we replace the boiler?
- Where the existing controls are an old mechanical timer and single room thermostat, replacing them alongside the boiler with weather compensation or a modern programmable thermostat usually improves comfort and efficiency more than the boiler swap alone. It's not compulsory, but it's often the single best-value addition to a new install.
- Is a boiler install a noisy, disruptive job?
- There's unavoidable noise — drilling for the flue, pipework, sometimes moving a cylinder — but a straightforward swap is usually done within a working day with the mess kept to the immediate work area. We dust-sheet the route in and out and clear away pipe offcuts and old parts before we leave.

Things we check around Cranmore
Signs a boiler repair is no longer the right call
A boiler that's failing repeatedly, needing a different part replaced every service, or over roughly ten to fifteen years old is approaching the point where continued repair costs more over time than replacement, particularly once a heat exchanger — the most expensive single part — starts to show signs of failure through leaks or reduced output. Efficiency is the other half of the calculation: an older non-condensing boiler running at 70-80% efficiency against a modern condensing combi at over 90% means a meaningful chunk of every unit of fuel burned in the old boiler is simply lost up the flue. We give a straight answer on repair versus replace based on the fault found and the boiler's age and condition, rather than defaulting to whichever is more profitable to us on the day.
Choosing a boiler location that satisfies both planning and practicality in Cranmore
On a property within a conservation area, AONB or World Heritage designation, the boiler's physical location is often decided as much by the acceptable flue route as by where the homeowner would naturally put it — a kitchen wall facing the street may need ruling out even before considering pipe run length, simply because the flue outlet would be visible from a protected streetscape. Working back from an acceptable flue position to find a viable boiler location sometimes means a longer pipework run through the property than would otherwise be chosen, adding to the job's cost and complexity. We assess planning constraints on the flue before finalising the boiler's proposed location, rather than picking the location first and discovering the flue route is unacceptable afterwards.
LPG as an alternative to oil off the gas grid
Properties around Cranmore that sit off the mains gas network aren't limited to oil — bulk LPG, stored in an above-ground tank on a concrete base with the same OFTEC-style clearance and access rules as oil, runs standard gas-rated boilers with only a change of injector and pressure setting rather than a different boiler entirely. It suits households that want a gas hob and gas-style modulation rather than an oil burner's on/off firing pattern. The tank still needs delivery access for a tanker, which on some rural driveways is the deciding factor over oil. We check the access route for the largest realistic delivery vehicle before recommending LPG over oil, because a tank that can't be filled easily causes more disruption than the fuel choice was meant to solve.
Wood-burning stoves with a back boiler alongside a main boiler
Some older rural properties around Cranmore run a wood-burning stove with a back boiler feeding heat into the same central heating circuit as an oil or gas boiler, usually through a thermal store or a cylinder with two coils. Getting this combination to work safely means the stove's back boiler circuit has its own means of dissipating heat if the pump fails or a valve closes while the stove is still burning — a stove can't simply be switched off the way a boiler can if its heat has nowhere to go, so a gravity-fed safety circuit or heat leak radiator is normally required. It's a more involved design than a single-boiler system and needs planning at the point either appliance is replaced, not treated as an afterthought once the new boiler is already fitted.
Nozzle replacement and baffle cleaning on oil burners
An oil burner's nozzle atomises fuel into a fine spray for combustion, and it wears from constant fuel flow at pressure, gradually changing the spray pattern away from the burner manufacturer's specification even before it visibly fails. A worn nozzle burns less cleanly, producing more soot that coats the heat exchanger's baffles, and a sooted heat exchanger loses efficiency in the same way scale does on a gas boiler's plates. Standard practice on an annual oil service is to replace the nozzle as a matter of course, rather than wait for a fault, and to remove and clean the baffles so the heat exchanger surfaces are exposed to combustion heat properly again. Skipping nozzle replacement to save a service visit's minor parts cost is a false economy against the fuel wasted by a poorly atomising burner.
Plume management kits for restricted flue positions
Where the ideal, shortest flue route would discharge too close to a boundary, a window, or onto a neighbouring property — a common constraint on tight plots in Cranmore — a plume management kit extends the flue's discharge point away from the boiler's own wall penetration, directing the visible water vapour plume and flue gases to a compliant location instead. It adds ductwork and sometimes a small additional fan to overcome the extra resistance, and it has to be specified against the specific boiler's approved kit range rather than improvised, since flue certification only covers tested combinations. It's a legitimate way to fit a boiler on a plot where the compliant flue route and the sensible boiler location aren't the same wall, without compromising on clearances to solve it.
Pumped-oil versus gravity feed: does it matter?
Older oil systems sometimes still rely on gravity feed, where the tank sits higher than the burner and oil flows down to it under its own weight; a pumped system uses the burner's internal pump to draw oil up from a tank at any level, including below the boiler. Gravity feed limits where a tank can be sited and is more prone to airlocks if the line runs dry, while a pumped system is more flexible on tank position but needs the pipe run and lift height kept within the burner pump's rated capacity — usually no more than a few metres of lift and a set maximum run length. When we replace an oil boiler we check which type the existing tank and pipework support before assuming a straight swap, because a tank sited for gravity feed may need repositioning or a different pump to suit a modern burner.
