Much of the built-up core has mains gas, but climb towards Overtown, Hackpen and the properties spread along the downland lanes and you are firmly in oil country. Those homes are typically older, larger and more exposed, which makes getting the installation right far more important than simply swapping one appliance for another. BTD Plumbing & Heating is OFTEC registered (business C11108, technician 28212) and a Grant UK G1 approved installer. Ben Davis carries out every installation personally, with 18 years' experience across oil, gas and plumbing, so there are no subcontractors and no handovers between trades. Our quotes cover the whole job: heat loss assessment, boiler specification and position, tank condition and siting, fuel line and fire valve, system cleansing, filtration, controls and commissioning paperwork.

Based in Broad Town, near Royal Wootton Bassett Gas Safe 529962 OFTEC C11108 Manufacturer accredited ## Grant UK G1 Approved Installer, fitting oil boilers in Wroughton Our Grant UK G1 approval is the reason most of our Wroughton oil work is Grant kit. On the older stone and brick properties climbing towards Barbury and the plots off Ellendune and Overtown Hill, boiler siting, flue routes and tank runs all need thinking about individually, and G1 assessment covers exactly that standard of install work. Every eligible Grant boiler fitted in Wroughton is registered for Grant's extended manufacturer guarantee at commissioning, and serviced by the same engineer who installed it, which keeps the guarantee valid without you having to arrange a separate contract. - New installations & replacements - Annual servicing & maintenance - Extended manufacturer guarantees on eligible models - Installed to Grant UK's exact specifications Local detail ## Wroughton, specifically Exposed downland properties Homes above Wroughton towards Overtown and Hackpen sit high and exposed. Heat loss is higher than a comparable house in a sheltered village centre, and boiler sizing needs to reflect that. Equally, external installations and tanks in these positions need proper thought about wind-driven rain, frost and condensate routing, which is where generic quotes tend to come unstuck. Mixed period and post-war housing The village runs from period stone and brick properties around Church Hill and the High Street, through substantial post-war family homes, to converted farm buildings and newer plots on the outskirts. Pipework in the older stock is often a patchwork of microbore and 15mm added over decades, and that has a real effect on how a modern condensing boiler performs. Hard water and system contamination Wroughton's chalk-fed supply leaves scale, and decades-old radiator circuits leave magnetite. Between them they will wreck a new condensing oil boiler's heat exchanger if the system is not cleansed first. Every installation we carry out includes a proper cleanse, inhibitor and a magnetic filter, and we will recommend a full power flush where the system warrants it. What goes wrong here ## The faults we see most in Wroughton Old boilers limping through winter Repeated lockouts, sooting and rising oil consumption usually mean an appliance at the end of its life. We give a straight opinion on repair versus replacement rather than automatically selling a new boiler. Tanks past their service life Split plastic, corroded steel, sinking bases and tanks sited too close to buildings are all common around the village fringe. Tank replacement is priced honestly alongside the boiler. Condensate freezing in exposed positions A poorly routed condensate pipe on a high, exposed Wroughton property will freeze and lock the boiler out in the coldest week of the year. Correct sizing, insulation and internal termination where possible prevent it. Undersized radiators after a boiler swap Fitting a condensing boiler onto radiators sized for a 1980s system means it rarely condenses. We check the emitters and flag what actually needs upgrading. How it works ## From first call to handover in Wroughton - Step 1 Survey the property Heat loss, existing pipework, radiator sizing, hot water demand, flue routing, tank condition and access, all assessed on site. - Step 2 Free written quote A specified proposal covering boiler, tank, fuel line, controls, cleansing and filtration with one clear total. - Step 3 Install Old appliance stripped out, new boiler positioned and piped, flue and condensate routed for an exposed site, fire valve and filter fitted. - Step 4 Cleanse and dose System cleansed, inhibitor added and a magnetic filter installed to keep the new heat exchanger clean. - Step 5 Commission and register Combustion analysed and set, OFTEC paperwork completed, Grant guarantee registered where eligible, and controls demonstrated before we leave. Why BTD ## What Wroughton customers actually get Grant UK G1 approved installer Eligible Grant Vortex installations can be registered for Grant's extended 10 year guarantee. Oil is core work, not occasional OFTEC C11108 and technician 28212, with oil-fired heating forming a large part of our week across rural north Wiltshire. One contract, one engineer Boiler, tank, pipework, controls and commissioning handled by the same person from survey to handover. Aftercare from the installer Annual servicing and any warranty attention comes from Ben, not a rota of unfamiliar engineers. In detail ## Oil Boiler Installation in Wroughton, properly explained The technical decisions behind a Wroughton job done once and done right. ### Sizing for an exposed site Heat loss on a detached property above Wroughton is materially different to the same floor area in a sheltered terrace. We calculate rather than estimate, because an oversized boiler short-cycles, wastes oil and shortens its own life, while an undersized one never recovers the property on a cold morning. The calculation also informs whether existing radiators can deliver the required output at condensing flow temperatures. ### Internal, external or outbuilding External boilers are popular where utility space is tight, and they simplify flue and combustion air. Internal installations keep the appliance protected and make condensate routing easier. Outbuilding and boiler house installations suit farm properties around Overtown. Each has consequences for noise, frost protection, servicing access and pipe runs, and we set them out at survey stage. ### Tank replacement and OFTEC siting Where a tank needs replacing we specify to current OFTEC guidance: adequate fire separation from buildings and boundaries, appropriate bunding, a level base sized for the tank, and a fill point that a delivery tanker can actually reach. Doing tank and boiler together avoids paying twice for isolation, draining and commissioning. ### Controls that let the boiler condense A modern oil boiler paired with sensible controls, proper zoning, a programmable room thermostat and correctly set flow temperatures, delivers noticeably lower running costs than the same appliance on a legacy time clock. We specify controls as part of the installation rather than treating them as an afterthought, and explain how to use them at handover. ### Commissioning, documentation and servicing Every boiler is set with a flue gas analyser and documented on OFTEC commissioning paperwork. We register the appliance with the manufacturer, register the Grant guarantee where applicable, and set out the annual service requirement clearly, since manufacturer guarantees depend on it being kept up.
