Barrow Gurney's Local Oil Tank Replacement Specialist

LPG as an alternative to oil off the gas grid

Properties around Barrow Gurney 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.

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.

How a condensing boiler recovers extra heat

A condensing boiler passes flue gases through a secondary heat exchanger before they leave the flue, extracting additional heat by condensing water vapour in the exhaust back into liquid, which is expelled as the mildly acidic condensate water down the drain. This is why every condensing boiler needs a condensate drainage route as part of its installation, unlike older non-condensing boilers, which simply vented hot dry gas straight out. The efficiency benefit only fully materialises when the boiler is actually condensing regularly, which needs a return water temperature low enough — generally below 55°C — for water vapour to condense in the first place. A condensing boiler run permanently at a high flow temperature can spend much of its time not actually condensing, which is one of the main reasons flow temperature settings matter as much as the boiler model chosen.

What a proper heating quote should include

A quote worth relying on states the specific boiler or equipment model, the labour and materials it covers, whether a system flush and magnetic filter are included, what happens to old equipment removal and disposal, and what's excluded — an unexpected gas pipe upsizing or asbestos-containing material discovered during removal, for example, which can't always be known before work starts. It should also state who's completing the Gas Safe or OFTEC notification and Benchmark commissioning record, since that's the paperwork that protects both the manufacturer's guarantee and the property's compliance history when it's sold. A vague one-line quote makes comparing genuinely different offers difficult, because two prices that look similar can cover very different scopes of actual work.

• Specific make and model, not just "combi boiler"
• Flush and magnetic filter stated as included or excluded
• Old equipment removal and disposal covered
• Notification and Benchmark record responsibility stated

Wood-burning stoves with a back boiler alongside a main boiler

Some older rural properties around Barrow Gurney 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.

Single-pipe circuits in older stone cottages

A lot of the stone cottages and farmhouses around Barrow Gurney were plumbed decades ago on a single-pipe gravity circuit, where each radiator draws from and returns to the same loop rather than having its own flow and return. It works, but radiators furthest from the boiler receive water that's already cooled after giving up heat to the ones before it, so the far end of the house is always the coldest. Converting to a two-pipe layout means new pipe runs, which in a stone cottage often means chasing lime plaster or lifting flagstones — not a trivial job. Where a full rewire of the pipework isn't wanted, we sometimes improve balance instead by oversizing the radiators nearest the end of the run and fitting TRVs to hold back the ones nearest the boiler.

What voids or protects a Worcester Bosch extended guarantee

Worcester Bosch's longer guarantee periods on qualifying installations are conditional on the boiler being installed and commissioned by an Accredited Installer, on an annual service being carried out (by any Gas Safe registered engineer, not necessarily the original installer) within the required window each year, and on system water quality being maintained to the standard set out in their published guidance — meaning a system flush at installation, correct inhibitor dosing, and in hard water areas a scale reducer or filter as specified. Missing a single annual service, or installing without the required water treatment, can reduce cover back to the manufacturer's standard guarantee period even if the boiler itself has had no faults. Keeping the Benchmark record and service history together is what lets a claim be assessed quickly if it's ever needed.
