Nunney Maintenance & Repair
A heating system fitted properly should be low-maintenance for years, which is why the detail in maintenance & repair matters more than it might seem at the time: correct sizing, clean pipework, and controls set up to suit how the household actually lives. We're Gas Safe registered, OFTEC registered and a Worcester Bosch Accredited Installer, and we fit accordingly from our workshop at 24 Bristol Road, Radstock BA3 3EE. Mains gas covers much of the area, with off-grid pockets, which changes the appliance shortlist. Conservation and listed constraints apply to parts of the area, so external work is checked first. In Nunney itself (BA11, Somerset) that usually means stone village homes with castle ruin, roughly 8 miles from the workshop.
Nunney: stock, water and fuel supply
Village lanes around here are sometimes narrow enough that arranging a specific arrival time matters more than it would on a wider suburban road, particularly if a new boiler, cylinder or radiators need to be carried some distance from where a van can park. We ask about this when scheduling the survey so the job itself isn't held up by something that could have been sorted in advance. Conservation and listed constraints apply to parts of the area, so external work is checked first. Most of what we open up here is stone village homes with castle ruin, which dictates flue routes and pipe sizing. Nunney is roughly 8 miles from our Radstock base via the unclassified. Typical property stock here: stone village homes with castle ruin. A meaningful share of properties around Nunney 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 Nunney usually get a same-week visit, with most common faults fixed on the first attempt.

Straight answers for Nunney homeowners
- Do you cover Nunney?
- Yes. Nunney is 8 miles from our workshop at 24 Bristol Road, Radstock BA3 3EE, reached via the unclassified, and it's a regular part of our working area. We're Gas Safe and OFTEC registered, so we cover both mains gas and oil work out here without treating it as a special trip.
- 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.
- What's actually checked during an annual boiler service?
- A service includes a visual and functional check of the boiler's casing and controls, flue gas analysis to confirm safe and efficient combustion, checking the flame picture and pressure, inspecting seals and condensate, and testing safety devices. It's a safety check as much as a performance one, and it's what keeps most manufacturer warranties valid.
- Do we need planning permission for a new boiler flue on a listed or conservation-area property?
- If the property is listed, Listed Building Consent can be needed for anything altering its appearance, including a new external flue terminal, even where the work itself would normally be permitted development. In conservation areas like parts of Nunney's setting, flue position and visibility from the street can also come under scrutiny. We flag this at survey rather than after ordering the boiler.
- We're a home attached to or near a small business premises — do you cover that kind of property?
- Where the heating system is a standard domestic boiler serving living accommodation, it's within our normal scope even if it sits next to or above a shop or workshop, which is a common layout around Nunney. Fully commercial systems and appliances are a different scope, so we'd confirm exactly what's being asked at enquiry stage.
- Do you cover all of Nunney?
- Yes — every street in BA11 that falls under Nunney, plus the lanes towards Frome and Trudoxhill. We're 8 miles away in Radstock, so most jobs are reached in well under half an hour.
Your next move in BA11
Finishing maintenance & repair isn't the end of the relationship — if something doesn't feel right once the system's been running for a while, get in touch and we'll come back and look at it. Annual servicing afterwards keeps the guarantee valid and the system running as it should. Call 07516 118198 and we will confirm a visit slot for BA11. homes alongside small commercial and agricultural premises make up most enquiries from this postcode. Access is lane access, so parking, spoil removal and delivery timing get planned in advance.

The parts of the job people rarely mention
Routing a flue through a listed or conservation-area property
Nunney falls within an area where listed building consent or conservation area rules can affect where a boiler flue is allowed to terminate — a plume on a principal elevation facing the street is often unacceptable even where it would technically clear manufacturer distances. Getting consent, where it's needed, has to happen before the flue is cut through a wall, not retrospectively. In practice this usually means routing the flue to a rear or side elevation even if that means a longer pipe run and an extra bend, or using a horizontal flue kit through a lower window reveal wall rather than the roof. We check with the relevant conservation officer's published guidance before quoting a flue route on a listed or Article 4 property rather than assuming the shortest run will be approved.
Chasing pipework into lime plaster and stone walls
Solid stone or cob walls finished in lime plaster, common in the older parts of Nunney, behave very differently to modern plasterboard when a pipe run needs chasing in. Lime plaster is softer and more porous than gypsum, so cutting a neat, consistent chase without blowing the surface needs a slower hand and finer disc than a stud-wall job, and any repair has to be made good in a lime-based skim rather than modern filler, which can trap moisture behind it and cause the patch to fail. On solid stone we sometimes surface-mount pipework in painted conduit instead of chasing, particularly where the wall is a significant structural thickness and chasing would weaken it. Knowing which approach a wall needs before starting avoids expensive plaster damage.
Low-loss headers on larger or multi-zone systems
On a system with several heating zones or a boiler oversized relative to any single zone's flow requirement, a low-loss header hydraulically separates the boiler's primary circuit from the secondary zone circuits, so each side can run its own pump and flow rate without one interfering with the other. Without it, a zone valve closing on a multi-zone system can starve the boiler of flow or force excessive pump pressure through the remaining open zones. It's most relevant on larger properties or ones with commercial premises attached, where several distinct heating circuits — perhaps a shop unit and a flat above — share one heat source. Getting the header sized to the boiler's actual flow rate, not just fitted as standard, is what makes it work rather than just adding another connection.
Wood-burning stoves with a back boiler alongside a main boiler
Some older rural properties around Nunney 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.
LPG as an alternative to oil off the gas grid
Properties around Nunney 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.
Radiator sizing after lowering the flow temperature
Running a boiler at a lower flow temperature — typically 55°C or below rather than the old default of 70-80°C — improves condensing efficiency measurably, but it also reduces the heat output of every radiator in the house, because a radiator's output falls roughly with the square of the temperature difference to the room. Radiators sized correctly for a 75°C flow can end up unable to heat the room properly at 55°C unless they're upsized or supplemented. We check each radiator against the lower design flow temperature before recommending it, and where a room falls short we look at whether a larger single panel, a double panel, or an additional radiator on that circuit closes the gap, rather than pushing the flow temperature back up and giving away the efficiency gain.
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.
Common boiler fault codes and what usually causes them
Most modern boilers display a fault code on the control panel when they lock out, and while the exact code differs between manufacturers, the underlying causes cluster into a small number of categories: low system pressure (often from a small leak or after bleeding radiators), ignition failure (a worn electrode, gas supply issue, or blocked condensate causing a safety shutdown), or a failed sensor reporting an implausible temperature reading. A condensate blockage or freeze specifically tends to show a distinct code from a genuine ignition fault, which is why checking the external condensate pipe for ice before calling out an engineer in a cold snap can sometimes resolve the issue without a visit at all. We ask for the exact fault code and any recent history — a bled radiator, a cold snap, a recent service — before attending, since it often narrows down the likely cause before we arrive.
