Vented hot water cylinder replacement and repair
Vented hot water cylinders are what we work on: the normal tank in the airing cupboard, fed by gravity from the cold water tank in the loft. We replace them and repair them. Send us photos on WhatsApp and we reply with a fixed quote.
What we do
Photos first, fixed quote, then the work
Four steps, so you know where you stand.
Step 1: Send photos
WhatsApp photos of the cylinder, its label, the pipes around it and the airing cupboard.
Step 2: Fixed quote
We reply with a fixed quote that says what is included, before any work starts.
Step 3: Old out, new in
We drain the old cylinder, take it out and fit the new one, then reconnect the pipework.
Step 4: Filled and checked
We refill from the loft tank, check every joint for leaks and test the hot water.
What is a vented cylinder?
A vented cylinder is the traditional hot water tank, usually copper, sitting in an airing cupboard. It is fed with cold water from a tank in the loft, and a vent pipe runs back up to that tank. The water is delivered to your taps under gravity from that tank.
If that sounds like your cupboard, you are in the right place. If you are not sure, send a photo and we will tell you.
Signs a cylinder needs attention
Water on or under the cylinder, damp in the airing cupboard, a ceiling stain below it, or hot water that runs out quickly can all point to a failing cylinder. A leak at a joint or fitting can often be repaired. If the cylinder itself is leaking, it needs replacing.
An older copper cylinder that is weeping, noisy or no longer holds its heat is worth looking at before it fails. Send photos and we will say whether a repair will do.
Heating the water
Many vented cylinders also have an immersion heater and thermostat. If that is what has failed, see immersion heater replacement, which we can do on its own.
