Central Heating Repairs& System Installations inHigh Wycombe

Sealed combi systems suit smaller properties with a single bathroom and mains pressure good enough to deliver a decent shower. They are simple, compact and lose nothing to cylinder standing heat, but they cannot serve two showers at once.

System boilers with an unvented cylinder are the usual answer for family houses with two or more bathrooms, giving mains-pressure hot water to every outlet simultaneously. Open-vented systems with a loft tank are still common in older Buckinghamshire homes and remain perfectly serviceable when maintained.

Choosing between them is about how your household actually uses hot water, not about what is fashionable. We calculate the demand and tell you which option genuinely fits.

Microbore (8mm and 10mm) pipework was fitted widely in the 1970s and 80s. It works, but its narrow bore silts up quickly and a partially blocked microbore tail is one of the most common causes of a single stubbornly cold radiator.

Standard 15mm and 22mm copper remains the backbone of most installations, with barrier plastic used where runs are buried in floors or need flexibility. Whichever is used, joints are kept accessible where possible and buried sections are pressure-tested before anything is covered up.

On full installations, pipe routes are planned to keep index runs short and balanced. That planning is invisible once the floors are back down, and it is the difference between a system that balances easily and one that never quite does.

Modern controls do more for running costs than almost anything else. Thermostatic radiator valves set each room individually, a room thermostat governs the main zone, and a cylinder thermostat stops hot water being reheated needlessly.

Zoning splits upstairs from downstairs, or a home office from the rest of the house, so you are not heating empty rooms to warm one. On larger properties this is where the savings genuinely accumulate.

Smart and programmable thermostats can be fitted where you want them, and we will set them up and show you how they work rather than handing you a manual on the way out.

A magnetic filter fitted on the return catches circulating magnetite before it reaches the boiler, and it is cleaned at each service. On any system that has been running for years without one, it is one of the cheapest upgrades available.

Corrosion inhibitor is dosed after any drain-down and its concentration should be checked periodically, because it depletes. Systems with strong inhibitor levels and a filter simply do not sludge up at the rate untreated ones do.

Where a system is already heavily contaminated, a power flush clears it before new components go in; otherwise the debris simply migrates into whatever is newest and narrowest.
