What is condensate and why does its routing matter?

Condensate is the mildly acidic water produced by a modern condensing boiler as it extracts extra heat from the flue gases, and it needs a route to an internal drain or, less ideally, an external soakaway. In colder or more exposed locations an external condensate pipe can freeze and shut the boiler down, so internal routing is worth prioritising where the layout allows it.

Being 13 miles out, does that add much time to booking a job in?

Distance from our Radstock base doesn't change how the job's priced or scheduled — we build travel into the working day rather than tacking on a surcharge. It can mean a very early or later start slot to fit the return journey around other bookings, which we'll confirm when we schedule.

We're on mains gas — is a boiler swap a fairly simple job?

Where the new boiler goes in the same place with the same flue route, a mains gas swap is usually the most straightforward job we do — often completed within a working day. It gets more involved if you're relocating the boiler, changing from a heat-only or system boiler to a combi, or the existing pipework needs upgrading to suit.

How do you decide whether to repair or replace a boiler?

We weigh the age of the boiler, whether parts are still made for it, how many faults it's had recently, and its running efficiency against a like-for-like or upgraded replacement. If a straightforward part fixes it and the boiler's otherwise sound, we'll say so rather than push a new install you don't need.

Do you cover Glastonbury?

Yes. Glastonbury is 13 miles from our workshop at 24 Bristol Road, Radstock BA3 3EE, reached via the A39, 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.

Do you cover all of Glastonbury?

Yes — every street in BA6 that falls under Glastonbury, plus the lanes towards Street and West Pennard. We're 13 miles away in Radstock, so most jobs are reached in well under half an hour.

Glastonbury Boiler Installation

Working across Radstock, Bath and the surrounding Mendip villages day to day means we see plenty of variation in how boiler installation needs to be approached — different building ages, different water supplies, different access. That local experience feeds into how we survey and quote, rather than working from a single generic template. Gas Safe registered, OFTEC registered, 24 Bristol Road, Radstock BA3 3EE. Nearest neighbours on our round are Street, West Pennard, Meare. a mix of owner-occupied and rented homes make up most enquiries from this postcode. In Glastonbury itself (BA6, Somerset) that usually means stone terraces, georgian and victorian housing, roughly 13 miles from the workshop.

Glastonbury: stock, water and fuel supply

Most properties in this settlement sit on the mains gas network, which keeps the fuel choice straightforward and generally opens up the widest range of boiler options. That doesn't remove every complication — flue routing, existing pipework diameter and how the property currently distributes heat still need checking — but it does mean the conversation usually starts from a simpler baseline than in the off-grid villages further out. We're Gas Safe registered for exactly this kind of work. Conservation and listed constraints apply to parts of the area, so external work is checked first. Access is narrow terrace, so parking, spoil removal and delivery timing get planned in advance. Glastonbury is roughly 13 miles from our Radstock base via the A39. Typical property stock here: stone terraces, Georgian and Victorian housing. Mains gas covers most of Glastonbury, so the usual choice is between a modern combi or a system boiler with a cylinder — we'll size it correctly for the home, not just swap like-for-like. When we quote boiler installation here we factor in flue routing, condensate fall and gas-supply pipe sizing before the price is fixed.

How to get this priced

Correct sizing matters more than most people realise for boiler installation: an undersized system struggles to keep up, and an oversized one costs more to run and buy than it needs to. We size against the property's actual heat loss and hot water demand, not a rule of thumb. Gas work is signed off Gas Safe; oil work is signed off OFTEC. Conservation and listed constraints apply to parts of the area, so external work is checked first. Mains gas is available across most streets, which changes the appliance shortlist.

The parts of the job people rarely mention

Gas pipe sizing and working pressure drop

Swapping to a higher-output combi or adding an extra gas appliance means the existing gas pipe has to be checked against the new total demand, not just the boiler's own rating plate. Gas Safe installation procedures require a working pressure test at the appliance under full load, and IGE/UP/2 tables set the maximum permitted pressure drop over the pipe run length and diameter. A run that was adequate for a 24kW back boiler can be undersized once a modern combi with a larger instantaneous hot water draw is fitted on the same 15mm supply. Where the test shows an unacceptable drop, the fix is upsizing to 22mm or shortening the run — not turning the boiler down, which just masks the underlying restriction.

Chasing pipework into lime plaster and stone walls

Solid stone or cob walls finished in lime plaster, common in the older parts of Glastonbury, 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.

Chimney liners for boilers using an existing flue

Where an older boiler used the property's original brick or stone chimney as its flue route, a replacement condensing boiler usually can't use the same masonry flue unlined, because the flue gases are cooler and wetter and will attack unprotected brickwork and mortar over time. A correctly specified stainless steel liner, sized to the boiler manufacturer's flue length and diameter tables, carries the flue gases safely and lets the existing chimney be reused rather than needing a new wall or roof penetration — often the only realistic option on a listed or solid-wall property in Glastonbury where an external flue run isn't permitted. The liner has to be inspected and swept as part of ongoing servicing exactly as an open-fire flue would be, which is easy to overlook once it's hidden inside the chimney.

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.

Oil tank de-sludging: why it's not optional

Oil sitting in a tank for years accumulates water from condensation and fine sediment that settles at the bottom, and over time this forms a sludge layer that can be drawn into the fuel line, particularly when the tank is nearly empty and the outlet pulls from lower in the tank than usual. Sludge blocks fine oil filters and burner nozzles, which shows up as burner lockouts or a boiler that won't fire cleanly rather than as an obvious tank problem. De-sludging drains and cleans the tank base without necessarily removing the whole tank, and it's worth doing when a tank is inherited with a property, before switching to a new boiler, or if lockouts recur despite the filter and nozzle being replaced. It's a preventative job that's cheaper done on schedule than after a burner failure it caused.

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.
