Testing Before Replacing
Elements and thermostats are tested so a part is replaced because it has failed, not because it was suspected.
Water Heater Thermostat and Element Replacement in Dubai
Failed thermostats and heating elements replaced to the unit's rating
In Brief
Thermostat and element replacement is swapping the parts that control and produce heat in an electric water heater. The thermostat sets the water temperature and the element heats the water. When either fails, the water may stay cold, overheat or trip the breaker, and the part is replaced with one matched to the unit.
In an electric storage water heater, the heating element is the part that gets hot and the thermostat is the part that decides when to switch it on and off. Both work in hard conditions: constantly heated, sitting in water and exposed to scale. Over time an element can burn out or become coated in scale, and a thermostat can stick, drift or fail.
We test the parts first, because a tripped safety cut-out or a power problem can look the same. If a part has failed, we replace it with one matched to the unit's rating, drain the tank where needed to reach it, refit and refill the unit, and test heating and the safety devices. This is part of our wider water heater repair. If the tank is corroded or the unit is old, we will tell you if replacing the unit is better value than fitting new parts.

What We Do
What Water Heater Thermostat and Element Replacement Covers
Heating Element Replacement
A failed or scaled-up element is replaced with one matched to the heater's rating and fitting.
Thermostat Replacement
A faulty thermostat is replaced and set so the water temperature is controlled correctly.
Draining and Refilling
The tank is drained where needed to reach the part, then refilled and checked for leaks and air before it is switched on.
Safety Device Check
The safety cut-out and pressure relief valve are checked at the same time, since overheating and faults often involve them.
Test and Temperature Set
We confirm the unit heats, that the temperature is stable and that the breaker holds.
Our Process
How It Works
- 1
Tell Us the Symptoms
Describe what the heater is doing, its age and type, and send a photo of the unit label so we can match parts.
- 2
Test the Parts
We isolate the power and test the element, thermostat and cut-out to find the failed part.
- 3
Replace and Refill
We replace the failed part, refill the tank and check for leaks, with the price confirmed before work.
- 4
Heat Test and Handover
We switch on, confirm heating and temperature control, and explain what was found.
Good to Know
What Affects Time and Cost
Every property is different, so we confirm the price before any work starts. These are the things that most often change the time and cost.
- Whether the element, thermostat or both have failed
- The type, age and rating of the heater and availability of matching parts
- How scaled or corroded the unit is
- How accessible the heater and its access panel are
- Whether replacing the whole unit is better value than new parts
FAQ
Water Heater Thermostat and Element Replacement Questions
If the unit has power but the water stays cold or lukewarm, or the breaker trips when it switches on, the element may be at fault. We test it to confirm.
No. Parts must match the heater's rating and fitting. We check the unit label and fit matched parts.
Often, yes, to reach the part safely. We drain, replace the part, refill and check for leaks before switching on.
A faulty thermostat may fail to switch the element off. This should be fixed promptly, and we also check the safety cut-out and relief valve.
It depends on the age of the unit and how scaled or corroded it is. We tell you honestly which is better value. See water heater installation if replacement makes sense.
