Vented and Unvented Hot Water Cylinder Installation
Most cylinders we're asked to replace are vented ones, fed by a cold-water storage tank in the loft. They've done their job for years, but the pressure at the shower rarely impresses anyone. An unvented cylinder takes its water straight from the mains instead. That's usually the swap people have in mind.
It's a hot water cylinder replacement with a bigger change behind it. The loft tank can go, the airing cupboard gets a sealed cylinder, and the pressure comes from the mains. Unvented cylinders are Norbert's own speciality. He's the plumber who quotes it, and he's the plumber who fits it.
Some homes suit a like-for-like swap better. If your mains pressure won't carry an unvented cylinder, we'll tell you. Plainly.

Unvented Cylinder Installation Process for Maidstone Homes
Nobody wants a plumber camped in their house. So the job's staged to keep the work in one place and the rest of the home running.
Looking first
We'll look at the airing cupboard, the loft tank and the incoming mains before anything's quoted. That's when we check the pressure and flow, and where the discharge pipe can run. No surprises. You'll know what's happening before a single pipe's cut.
The day of the swap
The water's turned off, the old cylinder's drained and it leaves by the same route the new one comes in. Dust sheets go down along that route. It's one man working, so it's a quieter job than you'd expect. Your kitchen and living room don't change hands.
Living with it
So what's it like to live with? Mostly, it's one cupboard out of action and no hot water while the cylinder's changed. Your cold water's back on as soon as the work allows. Once it's commissioned, the loft tank can come out, and that's space you get back.

Vented and Unvented Cylinder Repairs
A cylinder that's misbehaving usually tells you how. Water in the tundish, a drip outside, a shower gone lukewarm. Each one points somewhere.
Water from the discharge pipe
If water's running from the pipe outside, a safety valve is opening. That's often an expansion vessel that's lost its charge, or a relief valve that's worn. It's a hot water cylinder repair, and it's fixable, but don't leave it.
Pressure that comes and goes
Uneven pressure often traces back to the pressure reducing valve on the incoming mains. When it fails, you'll feel it at every tap. We'll test it, and replace it if it's past saving.
No hot water at all
With no hot water, we'll check the cylinder's controls and its immersion heater first. We repair and replace immersion heaters too, so that's covered. And on an older vented cylinder, leaking joints and tired valves are straightforward plumbing we're happy to sort.
Benefits of Mains-Pressure Hot Water in Maidstone
Mains pressure changes how the house feels at seven in the morning. That's the honest reason to switch.
- Showers that don't fade when somebody runs a tap downstairs
- A loft that's free of the cold-water storage tank
- There's no tank up there to freeze in a cold Kent winter
- Hot water that's stored in a sealed cylinder, not an open tank
It's not a gadget. It's a better daily routine, and the work's backed by a one year warranty on parts and labour.
Hot Water Cylinder Servicing and Maintenance
An unvented cylinder runs under pressure, so its safety parts need checking every year. That's what the annual check is for. It's not paperwork.
On the visit, we'll check:
- the expansion vessel's charge, topped up if it's dropped
- the temperature and pressure relief valve, operated so it doesn't stick
- the pressure reducing valve and the strainer that's in front of it
- the tundish and discharge pipe, so you'll see any water that's escaping
We don't touch the boiler that heats the water. That's for a registered gas engineer. The cylinder, its valves and its pipework are what we're there for.
How Unvented Hot Water Cylinders Work
There's no tank in the loft feeding it. Cold water comes in from the mains, it's heated inside a sealed cylinder, and it leaves at mains pressure.
Direct and indirect heating
A direct cylinder's heated by its own immersion heater. An indirect one carries heat in through a coil inside it. Twin coil cylinders take two heat sources. It's the same sealed vessel either way.
The safety parts
Heated water expands, and in a sealed cylinder it's got nowhere to go. The expansion vessel takes that extra volume. If something fails, the temperature and pressure relief valve opens and sends water safely through the tundish. That's why they matter.

Common Questions About Unvented Cylinder Installation And Repair in Maidstone
How often should a hot water cylinder be serviced?
An unvented cylinder should be checked every year. It's under pressure, so the expansion vessel, the temperature and pressure relief valve and the pressure reducing valve all need looking at annually. Checking unvented cylinders is Norbert's own speciality, and he tells you plainly what's wearing. Simple, and worth doing.
Do you cover Maidstone and the rest of Kent?
Yes. We cover Maidstone and the towns around Sevenoaks across Kent and Medway, as well as Surrey, East Sussex, West Sussex and south-east London. Everything north of the Thames is outside the area. Wherever you are in Maidstone, the plumber who quotes your cylinder is the plumber who turns up to fit it.
What should I do if my unvented cylinder starts leaking in Maidstone at night?
Turn the water off at the stopcock, switch off the cylinder's immersion heater, then call. We run a 24-hour emergency call-out across Maidstone. Don't ignore water from the discharge pipe either. It usually means a safety valve is opening, often because the expansion vessel's lost its charge, and it's a repair worth doing quickly.
Can you fit an unvented cylinder where my vented one is now?
Usually, yes. If your mains pressure and flow are good enough, the new cylinder often goes in the same airing cupboard and the loft tank can come out. Norbert quotes every job himself, once he has seen your supply. If it won't carry an unvented cylinder, we'll say so. Every installation carries a one year warranty on parts and labour.
