Urgent service when your water heater fails completely
Most water heaters in Dubai last around 8 to 10 years. Some go longer if they've been serviced regularly and the water quality in your building isn't too harsh. But Dubai's hard water is brutal on tanks — the limescale build-up alone can cut years off the lifespan. And the heat doesn't help either.
These are the signs we look for when we arrive at a job. If you're dealing with more than one of these, replacement is almost certainly the right call:
Even if it's still limping along, you're close to the end. Replacing it now on your own terms is better than replacing it at 2am on a Friday when the tank finally gives out.
That's internal corrosion — the inside of the tank is breaking down. No amount of repair fixes that. Once the tank starts rusting internally, replacement is the only option.
If there's water pooling around the unit or the tank itself looks damp and corroded on the outside, it needs to go. Tanks don't un-leak.
If you've paid for repairs in the last couple of years and something else has now gone wrong, at a certain point you're just throwing money at a dead unit.
If the water takes much longer to heat up than it used to, or you're running out of hot water mid-shower when that never happened before, the unit is losing capacity.
That's limescale build-up from Dubai's hard water superheating at the bottom of the tank every time the element fires. Left untreated, it accelerates the tank's breakdown significantly.
If your heater is under 5 years old and you have one clear, simple issue — a faulty thermostat, blown element, or stuck valve — repair can absolutely make sense. We'll tell you honestly when we arrive. We're not going to push a full replacement if a AED 200 fix gets you another 3 years.
Tick everything that applies to your situation. We'll tell you which way to go — and why.
These are the real numbers we're charging right now — not optimistic estimates, not 'starting from' prices that somehow never apply to your situation.
These prices cover labour, standard installation, and removal of your old unit. If your setup needs extra pipe work — older Bur Dubai buildings sometimes do, or if you're changing tank size and the fittings don't line up — we'll tell you the exact additional cost before we start. No surprises on the bill.
💳 Cash, card, or bank transfer — whatever works for you.
We install and replace all the major brands you'll find in Dubai. Here's a quick breakdown of what's available and who each one actually suits.
More Brands We Service
Ask us when you call. We'll give you a straight recommendation based on your property type and budget — not based on which one has the highest margin for us.
The standard in most Dubai apartments. Tank stores heated water continuously. Simple, reliable, parts are easy to source anywhere in the city. If you don't know what type you have, it's probably this.
More common in older villas. They heat fast and running costs are lower, but the replacement is more involved — we check gas connections, pressure, everything. Don't cut corners on gas installations.
Heat water on demand, no storage tank. Great for studios and smaller apartments, increasingly common in newer Dubai buildings. AO Smith and Rheem both have solid tankless options right now.
More of a villa thing. Dubai sunshine makes them genuinely practical and they do cut DEWA bills meaningfully over time. Replacement is more involved — rooftop panels and a tank — but we handle the full job.
150L and above, or multi-point systems for larger buildings. We handle these too — call and we'll assess what your setup actually needs.
People always want to know what they're getting into. Fair enough. Here's exactly what happens:
Heater type, rough size, your location. Takes maybe two minutes. We give you a time window.
Technician checks the unit and confirms the exact price before starting. If something unexpected comes up — unusual pipe configuration, anything like that — we tell you before we start, not after.
We shut off the water supply and drain the old tank. This takes a bit of time and there's no way to rush it properly.
New unit goes in, connected, sealed, checked. We test it before we pack up — hot water running, no leaks, thermostat set correctly.
Your bathroom or utility room looks the same as before we arrived, just with a new heater.
If you're replacing like-for-like, we match your existing size. But if the current one has never kept up with your household, here's a rough guide.
Studios and very small apartments. Fine for one person, fits in tight spaces.
1-bed apartments. Works well for 1 to 2 people with normal usage.
Standard 2-bed apartments, families of 2 to 3. The most common size we replace across Dubai.
Larger apartments, smaller villas, or 2-bed setups with high usage.
Bigger villas, multiple bathrooms. Don't undersize this — you'll feel it.
Large family villas or commercial properties. Don't compromise here.
If you're thinking of going bigger because the current one never keeps up, the issue is sometimes a faulty element or thermostat — not capacity. We'll check both before recommending anything.
We replace and repair water heaters across all major areas in Dubai — apartments, villas, and commercial properties. Same-day service available across all locations.
We cover all of Dubai. Call us and we'll confirm availability for your location.
Honestly — the bar in this industry isn't that high. "Shows up when they say they will" is already enough to put you ahead of most of the competition here.
We show up. We tell you the price before we start, not after. We don't walk out leaving you to deal with your old tank. And we pick up the phone at 11pm when your heater decides to pack in the night before guests arrive.
We've been doing this long enough that water heater replacements aren't stressful for us. The job that leaves a homeowner panicking is just another Tuesday for our technicians. That experience matters — in how fast the job gets done, and whether it's done properly the first time.
"Called at 10am, they were at my apartment in JVC by 1pm. New heater installed, old one gone, hot water working by 3. Price on the phone was the price on the bill. Nothing fancy about it — just a job done properly."
"My heater started leaking on a Friday evening. I honestly expected to wait until Sunday. They answered immediately, came within 2 hours, replaced the whole unit. I was genuinely surprised."
"They came to replace my heater and actually told me I didn't need a full replacement — just a thermostat. Saved me probably AED 900. That kind of honesty isn't common. I'll use them for everything going forward."
"100L Ariston in our villa. Clean job, no damage to the wall, showed me what they were doing and why. Professional throughout."
Depends on the tank size. A 30L unit starts from AED 750 to 950. An 80L — which is what most 2-bed apartments in Dubai have — runs AED 1,000 to 1,250. Larger 150 to 200L tanks for villas go up to AED 1,900 to 2,500. All prices include labour and removal of the old unit. We confirm the exact number before we start.
Usually 2 to 3 hours on-site. Smaller units in easy-access locations can be quicker. Large tanks, or older properties where the pipes are a bit of a puzzle, can run closer to 3 to 4 hours. We'll be upfront about it if your setup looks like it'll take longer.
If the heater is under 7 years old and there's one clear simple fault, repair is often fine and we'll say so. If it's 8-plus years old, if it's broken down multiple times, or if there's water coming out of the tank itself — you're replacing it. We'll look at it and give you a straight answer.
For most Dubai apartments: 50 to 80L covers 1 and 2-bed units comfortably. Studios usually have 30L. Villas start at 100L and go up to 200L depending on bathrooms and how many people. If you're not sure, just tell us your property type when you call.
Yes. Most of the time, if you call before noon, we're there the same afternoon. We also work evenings and weekends — water heater problems have terrible timing and we know that.
Ariston, Super General, Zenith, Milano, Atlantic, Rheem, AO Smith. All the main brands in Dubai. If you've got a specific brand in mind, let us know. If you don't, we'll recommend one based on your property and budget.
Yes. Removal and disposal of the old unit is included in the price. You don't have to do anything with it.
We cover the installation work itself. The unit also comes with the manufacturer's own warranty — usually 1 to 3 years depending on brand and model. We'll tell you exactly what's covered for the specific unit we're installing.
Yes. 24/7, including Friday, Saturday, and public holidays. Dubai life doesn't stop on weekends and neither do we.
Tank is leaking — that's the clearest one. Rusty or discoloured hot water. Heater is 8 or more years old. You've already repaired it once or twice. It's making banging or rumbling noises from limescale build-up. You're running out of hot water faster than you used to. Any two of these together and it's almost certainly time to replace.
Improper electrical connections can cause shocks, fires, or electrocution. DEWA-compliant wiring requires certified electricians.
Incorrect gas line installation can lead to dangerous gas leaks, explosions, or carbon monoxide poisoning.
Missing or incorrectly installed pressure relief valves can cause tank explosions from excessive pressure buildup.
Poor connections result in leaks causing extensive damage to floors, walls, and ceilings.
Manufacturer warranties are voided if installation is not performed by licensed professionals.
Non-compliant installations fail inspections, require costly reinstallation, and create insurance liability issues.
Professional installation from Plumber Dubai guarantees safety, compliance, proper warranties, and long-term reliability.

Technically, the Water Heater replacement should be left to a professional. Here's why: A water heater is not only difficult to install but if installed incorrectly can leak or burst.
Water heaters have extremely high pressure and if that pressure is released through an improper installation or when you least expect it, serious damage can occur. Never attempt to change your water heater yourself unless you are a qualified and licensed plumber.
