Domestic Immersion Heater Installation
Most immersion heaters live in an airing cupboard. They screw into a brass boss on a copper cylinder and are wired to a switch on the wall beside it. That arrangement has barely changed in decades, which is good news: a new immersion heater usually goes into the fitting that is already there.
A fresh installation starts at the switch. We check the double-pole isolator, the flex and the heat-resistant cable before anything goes near the tank, because a new element on tired wiring only moves the fault. Then we drain the cylinder, fit the element on a new fibre washer, and set and test the thermostat.
Some cylinders carry two elements, one near the top and one low down. The lower one heats the whole tank on off-peak electricity overnight. The top one boosts a smaller amount during the day. If your cylinder has both, we look at both, because one failed element often explains a tank that runs cold by teatime.
Most installs are that simple.

Water Heater Replacement
An immersion heater that has stopped working is rarely as dead as it looks. The element, the thermostat and the wiring each fail in their own way, and only some of those failures mean replacement. So we test before we quote.
These faults are repairs, and we treat them as repairs:
- A thermostat that no longer clicks in or out, or has tripped its safety cut-out
- Wiring scorched or loose at the terminals
- A connection at the switch or the flex that has worked loose
- A fibre washer weeping at the boss
These need a new part:
- A burnt-out element, which reads open circuit on a meter
- An element seized in the boss by limescale, where forcing it would risk the cylinder
- A unit where the element will not draw current at all, even with a sound thermostat
A meter reading across the element and a check of the thermostat decide it. Nobody guesses. A good element with a failed thermostat needs a thermostat, nothing more. Selling you a whole immersion heater for that fault would be the dearer option by default. If the cylinder itself is weeping around the boss, that is a cylinder conversation, and we say so before any work starts.
Maidstone and Royal Tunbridge Wells both sit inside the area we cover, and an immersion heater installation in Royal Tunbridge Wells gets the same order of testing: element, thermostat, wiring. Test first, then decide.

Installation and Repair Process in Maidstone
An airing cupboard tells you a lot before a tool comes out. Scorch marks on the switch plate, a damp shelf under the cylinder, a jacket pulled loose at the top: each one points somewhere. We read those first.
The job in a Maidstone home runs in a fixed order:
- A conversation about what the hot water is doing, then a quote from the plumber who will do the work
- Power isolated at the switch and proved dead
- Cold feed shut off and the cylinder drained down through the drain cock
- Element and thermostat out with an immersion spanner, boss cleaned, new washer fitted
- Refill, check every joint for weeps, then power up and test the thermostat through a full heat

Hot water faults rarely travel alone. A cylinder that runs cold often sits above a shower giving trouble too, so an immersion heater replacement and repair in Maidstone can share a visit with a bath and shower repair in Maidstone. One trip, one plumber.

Electric and Tankless Water Heaters
An immersion heater is an electric water heater that happens to live inside a stored tank. A tankless unit heats water as it passes and stores none. Most houses already own one of those: the electric shower on the bathroom wall.
The two fail differently. A stored tank with a dead element gives you a lukewarm cylinder and a slow reheat. An electric shower fault shows at the head, in pressure or temperature, and that work sits on the shower side of what we do. On the cylinder, our work is the immersion heater: the element, the thermostat and the wiring that feeds them. Unvented cylinders are a speciality of their own, and the checks on those follow the same habit. Find the fault, name it, then quote.
The airing cupboard often has company. A tap dripping on the landing basin, a stiff isolating valve on the cold feed: an immersion heater replacement and repair in Maidstone and a leaking tap repair in Maidstone fit into one visit. Homes in Maidstone and Sevenoaks call for the same work, and our page on immersion heater repair in Sevenoaks covers that town.

Do you cover Maidstone and the villages around it for immersion heater work?
Yes. Maidstone sits inside the area we cover, which runs from Sevenoaks across Kent, Medway, Surrey, East Sussex, West Sussex and south-east London. Anywhere north of the Thames is outside it.

Who actually comes out to an immersion heater job in Maidstone?
Norbert. Vision Plumbing is a sole trader, so the plumber who quotes your immersion heater is the plumber who turns up, drains the cylinder and fits the part. Nobody else is sent. You explain the fault once, to the person doing the work, and every job carries a one year warranty on parts and labour.
I rent out a house in Maidstone. Can you fix the immersion heater between tenants?
Yes. We work for landlords and letting agents as well as homeowners, and the visit is arranged around access to the property and the keys. The element, thermostat and wiring are tested, the fault is named, and you hear plainly if it was a repair or a replacement, so the next tenant moves in with hot water.
How much does an immersion heater repair cost?
It depends on the fault, so we never quote a figure blind. A failed thermostat is a smaller job than a seized element, and a loose connection is smaller again. Tell us the symptoms and we will talk it through. The quick quote follows from that conversation, and it covers the fault we actually find.
My immersion heater is leaking at night in Maidstone. Can you come out?
Yes. Water coming from the boss or the cylinder is an emergency, and the 24-hour emergency call-out covers it. Turn off the immersion switch at the wall first. Then shut the cold feed to the cylinder if you can reach it. Then call. We find out if the washer, the element or the tank is the source.
