Signs You Need a New Cylinder

Signs Your Kensington & Chelsea Home Needs a New Hot Water Cylinder

Cylinders typically last 10 to 15 years, and many properties across Notting Hill and Holland Park are still running original units well past that age. Here are the signs our engineers see most often.

 

Leaking from the cylinder or fittings

Water pooling around the base of the cylinder or damp patches in the airing cupboard usually means the tank itself has started to corrode and fail — a clear sign replacement is needed, and particularly important to address quickly in mansion blocks where it could affect the flat below.

Inconsistent or insufficient hot water

A cylinder that can't keep up with demand, or produces lukewarm water where it used to run hot, often points to a failing heating coil or a cylinder that's simply too small for the household.

Rumbling or banging noises

Scale build-up inside an older cylinder can cause kettling and banging noises, particularly in the borough's older systems that have never been serviced or descaled.

Cylinder is over 10–15 years old

Even without an obvious fault, an older cylinder becomes more prone to sudden failure over time. Many Kensington & Chelsea homeowners choose to replace proactively rather than risk a leak.

Vented vs Unvented

Choosing the Right Cylinder for Your Kensington & Chelsea Home

The right cylinder type depends on your existing system, available space and hot water demand.

 

Vented cylinders

Fed by a cold water tank in the loft, vented cylinders are typically the lower-cost option and suit properties without the space or budget for an unvented upgrade — common across Notting Hill and Holland Park's period townhouses.

Unvented cylinders

Fed directly from the mains, unvented cylinders deliver strong, consistent pressure to every outlet without needing a loft tank — a popular upgrade for mansion block flats in South Kensington and Chelsea without loft space for a tank.

Old cylinder in our Notting Hill airing cupboard had started leaking. Replaced same day with a like-for-like unit, tidy job and explained the warranty clearly.

No space for a loft tank in our South Kensington mansion flat, so a compact unvented cylinder was fitted instead. Water pressure is fantastic now compared to before.
