    Unvented Cylinder Installation & Servicing in Bromley

    Installation, servicing and repair of unvented hot water cylinders, carried out by an engineer holding the G3 qualification.

    Unvented cylinder work for Bromley homes

    Bromley mixes Victorian and Edwardian terraces near the town centre with post-war semis and newer apartment blocks around Bromley South. Older properties often still run on aging copper pipework and first-generation combi boilers, while the newer flats tend to use sealed heating systems and unvented cylinders.

    Bromley is where London Flow is based, so it is the quickest area for us to reach for both booked appointments and urgent call-outs.

    Whatever the property, the approach is the same: find the real cause, explain it in plain terms, and agree the price with you before any work starts. Bromley is part of our Bromley and South East London coverage.

    Unvented Cylinder Installation & Servicing in Bromley: common questions

    Why does an unvented cylinder need servicing?

    Safety components such as the expansion vessel and relief valves wear over time. Annual servicing keeps the system safe and protects most warranties.

    Who is allowed to work on one?

    Unvented hot water work requires the G3 qualification, which we hold, so Bromley homeowners can have the cylinder serviced or replaced correctly and legally.

    My hot water pressure has dropped, is the cylinder at fault?

    It can be, though a failed expansion vessel or a partly closed valve is just as common. We test rather than guess.
