Vented and Unvented Hot Water Cylinder Installation
A vented cylinder is fed by a cold-water storage tank in the loft, so the pressure at your shower depends on how high that tank sits. An unvented cylinder takes its water straight from the mains and stores it under pressure. No loft tank. We install both, and we convert one to the other.
Before any cylinder is ordered, four things get measured or settled:
- Mains pressure and flow rate, tested at the incoming supply, because an unvented cylinder can only deliver what the mains gives it
- Capacity in litres, matched to the number of bathrooms and hot water outlets running at once
- Direct or indirect: a direct cylinder heats by immersion heater, an indirect one through an internal coil, with twin coil models where the design needs them
- The discharge route: the pipe from the tundish has to fall to a safe, visible outlet, and that decides where the cylinder can stand
Get those wrong and the new cylinder disappoints from day one. A strong vessel on a weak supply gives you weak hot water, only more expensively. So the measuring comes first, and we talk you through the readings before anything is quoted.

Hot Water Cylinder Servicing and Maintenance for Royal Tunbridge Wells Homes
An unvented cylinder holds hot water under mains pressure. Its safety comes from a small set of valves that only protect you if they are tested. That is what the annual check is for, and we work through it in order:
- Isolate the cold supply and the heat inputs, then relieve the pressure
- Check the expansion vessel charge and top it up if it has dropped
- Manually ease the expansion relief valve and the temperature and pressure relief valve, confirming each opens and reseats
- Check the pressure reducing valve is holding the working pressure steady
- Clean the line strainer on the cold inlet
- Inspect the tundish and discharge pipe for any sign of water passing
- Test the immersion heater thermostat and cut-out, and look over every joint for weeps
Skip it for a few years and the first sign of trouble is usually water running from the tundish. The check is the same in Royal Tunbridge Wells as it is alongside hot water cylinder installation in Sevenoaks, and the same plumber does it in both towns. If you want a cylinder plumber close to home in Royal Tunbridge Wells, the annual check is the easiest job to start with.

Vented and Unvented Cylinder Repairs
Most unvented cylinder faults sit in the controls, not the vessel. That matters. A valve is a repair, and a split stainless steel vessel is a replacement.
- Water dripping from the tundish: usually an expansion vessel that has lost its charge, or a relief valve letting by
- Pressure rising and falling at the taps: a pressure reducing valve that has started to fail
- Poor flow on a good mains: a blocked inlet strainer
- No hot water: an immersion heater element, its thermostat or a tripped cut-out
- Water at the base of the cylinder: a weeping joint, or on an old unit, the vessel itself
Vented cylinders fail differently. Copper thins with age, the ball valve in the loft tank sticks, and a pinhole leak in the cylinder wall means a new one. We repair what can be repaired and say plainly when it cannot.
A dripping pipe is not always the cylinder. One visit can cover an unvented cylinder installation and repair in Royal Tunbridge Wells, or move on to water leak detection in Royal Tunbridge Wells if the water is turning up somewhere the cylinder does not explain. Landlords with cylinders in tenanted flats get the same work through our commercial plumbing in Royal Tunbridge Wells, arranged around tenant access.
Benefits of Mains-Pressure Hot Water
Mains-pressure hot water reaches every tap at a working pressure set by the pressure reducing valve on the inlet. The practical gains:
- A shower that holds its force when a second tap opens
- Two bathrooms running together without one going weak
- No cold-water storage tank, so nothing in the loft to freeze, overflow or collect debris
- Balanced hot and cold pressures at mixer taps and thermostatic showers
- A cylinder that no longer relies on gravity, so it can sit wherever the discharge pipe can run
Every one of those gains depends on the mains. That is why the survey reading matters so much. And once the cylinder is in, the plumber who fitted it carries out our hot water cylinder repair services, so its history stays with one person.
Unvented Cylinder Installation Process
Across the trade, an unvented cylinder installation usually takes one to two days, depending on the existing pipework. It runs in four stages.
1. Survey and measurement
We measure mains pressure and flow, check the cylinder position and plan the discharge pipe route. Size and type are settled here.
2. Drain-down and removal
The old cylinder is isolated and drained. On a conversion from vented, the loft tank and its pipework come out and the cold feed is rerouted from the mains.
3. Fitting the cylinder and controls
The new vessel goes in with its inlet group: line strainer, pressure reducing valve, check valve and expansion relief valve, plus the expansion vessel. The temperature and pressure relief valve and tundish are fitted, and the discharge pipe is run to its outlet.
4. Filling, testing and handover
We fill the system, purge the air and check every joint under pressure. The relief valves are tested, the immersion heater is connected and checked, and you are shown where the isolating valves are. Done.

Unvented Cylinder Installation And Repair in Royal Tunbridge Wells: Your Questions Answered
How much does it cost to install an unvented cylinder in Royal Tunbridge Wells?
That depends on the cylinder size, whether a loft tank is coming out and how far the discharge pipe has to run, so we do not publish prices. We measure your mains pressure, look at where the cylinder will sit and then quote. A quote follows a conversation. Get a quick quote and we will start there.
How long does it take to fit an unvented cylinder?
Across the trade, usually one to two days, depending on the existing pipework. A straight swap of one unvented cylinder for another sits at the shorter end. Converting from a vented system takes longer, because the loft tank comes out and the cold feed is rerouted. We tell you when the hot water will be off before work starts.
Do unvented water cylinders need servicing?
Yes, once a year. The check tests the expansion vessel charge, both relief valves, the pressure reducing valve and the immersion heater cut-out, and cleans the inlet strainer. Those valves protect a vessel holding hot water under mains pressure. Left untested, the first warning is often water running from the tundish.
Can I fit my own unvented cylinder?
We would not advise it. An unvented cylinder is a pressurised vessel, and its safety depends on the inlet group, relief valves and discharge pipe being fitted and tested correctly. It is also work that building regulations control. Get it wrong and the risk is water damage, or worse. Leave it to a plumber who installs them.
Do you cover the whole of Royal Tunbridge Wells?
Yes. Vision Plumbing covers Sevenoaks and the towns around it across Kent, Medway, Surrey, East Sussex, West Sussex and south-east London, and Royal Tunbridge Wells sits inside that area. Wherever you are in the town, the plumber who quotes your cylinder job is the one who turns up to do it. There is no call centre in between.
Can my Royal Tunbridge Wells home switch from a loft tank to an unvented cylinder?
Often, but the mains decides. We measure the pressure and flow rate at your incoming supply first, because an unvented cylinder can only give back what the mains provides. If the readings are good, the loft tank comes out, the cold feed is rerouted and the new cylinder goes in with its safety controls.
