Unvented Cylinders in Chislehurst
Chislehurst is exactly the sort of area where unvented cylinders are the norm — substantial detached and semi-detached family homes across BR7, a lot of period property around the Common and Camden Park, and plenty of houses with three or four bathrooms that simply cannot run on a gravity-fed tank in the loft.
I am roughly ten minutes away in Orpington, so Chislehurst is genuinely local for me — which matters when a cylinder fails and you have no hot water.
Period properties and awkward siting
Older Chislehurst houses often have cylinders in unusual places following extensions and conversions. The discharge pipework routing is where I find the most non-compliance, particularly undersized manifolds where two relief valves have been combined.
Larger homes, higher demand
Three or four bathrooms running at once puts real demand on the cylinder and its controls. Annual servicing matters more here, not less — and it is exactly where a neglected expansion vessel shows up first.
Hard water and scale
Chislehurst sits in a hard water area. Scale in the inlet control group and on immersion heaters is routine, and a blocked strainer is the usual reason hot water pressure drops while the cold stays fine.

Almost every cylinder I attend had been dropping hints for months. None of these are dramatic, which is exactly why they get ignored.
Visible corrosion or damp around the base
Sometimes condensation, sometimes a genuine weep. Either way it wants identifying before it marks a floor or a ceiling below.
Rusty or discoloured hot water
Worth investigating quickly. On an indirect cylinder it can point at the coil; elsewhere it may be pipework rather than the vessel.
Hot water runs out sooner than it did
Often a failing immersion, a scaled coil, or a thermostat that has drifted out of calibration. All repairable, all cheaper caught early.
The pressure gauge keeps falling
Topping up regularly is not normal. Water is escaping somewhere, and each top-up brings in oxygenated water that corrodes from the inside.
Reduced flow at every hot outlet at once
Points at the cylinder or its controls rather than an individual tap, and is usually the pressure reducing valve or the strainer.
What You Will Pay
Servicing a cylinder and an air source heat pump in the same visit is £270 instead of £170 and £140 separately. That is £40 saved, and it makes sense because one heats the water the other stores.
Repairs are quoted separately at a fixed price agreed before I start — typically a combination valve, an expansion relief valve, a T&P valve, or re-priming a vessel. None are expensive jobs.
A full G3 annual service is £140 with no VAT — I am not VAT-registered, so that is the whole price rather than a figure with twenty percent waiting behind it.
