No hot water? Heater leaking or tripping the ELCB? Ace Plumber Johor Bahru diagnoses and repairs all water heater types across Johor Bahru — instant, storage, and gas models. We carry common replacement parts and fix most heaters in a single visit.
From instant heaters to storage tanks — these are the water heater problems we solve daily across JB homes.
Heater powers on but water stays cold. Usually a burnt heating element, faulty thermostat, or limescale buildup on the element. We diagnose the root cause and replace the failed part.
Water dripping from the unit, connections, or pressure relief valve. Could be a corroded tank, loose fitting, or excessive pressure. We identify the leak source and fix or replace the component.
Water heater causes the circuit breaker to trip every time it's turned on. This is usually a grounding fault in the heating element — a safety hazard that needs immediate attention.
Water is lukewarm but never reaches a comfortable temperature. Often caused by a failing thermostat, partially burnt element, or undersized heater for your shower head's flow rate.
Popping, rumbling, or hissing sounds from the water heater. In storage tanks, this is usually sediment buildup on the heating element. In instant heaters, it may indicate a failing flow sensor.
Hot water comes out as a trickle even though cold water pressure is normal. Usually caused by a clogged inlet filter, scaled-up heat exchanger, or failing flow switch inside the unit.
Quick diagnosis, honest quote, proper repair.
Tell us the heater brand, model, and what's wrong. A photo of the unit and any error indicators helps us prepare the right parts.
Our plumber inspects the heater, tests the electrical and plumbing components, and tells you exactly what's wrong and how much it costs to fix.
We replace the faulty part, test hot water output, and check ELCB function to make sure everything is safe. You only pay the quoted price.
Many handymen just reset the ELCB or tighten a loose wire and call it done. The problem comes back within days because the root cause was never addressed. Our plumbers test the heating element's insulation resistance, check thermostat calibration, inspect for limescale buildup, and verify the ELCB protection circuit. We fix the actual problem so it doesn't come back.
Instant shower heaters, storage tank heaters, multipoint heaters, and gas water heaters — we service them all. We carry common elements, thermostats, and flow sensors for quick replacement.
Water heaters combine electricity and water — a dangerous combination if not maintained properly. We test earth leakage, element insulation, and ELCB function after every repair.
If your heater is beyond economical repair, we'll tell you upfront rather than charge for a fix that won't last. We can also supply and install a replacement unit if needed.
We service all major water heater brands found in Malaysian homes and carry replacement parts for the most popular models.

"The ELCB kept tripping every time we turned on the water heater. They found a wiring issue at the connection point, fixed it, and tested the safety switch. Everything is working safely now."
"Our storage heater was leaking from the bottom. They assessed it honestly and told us the tank had corroded — repair was not worth it. Helped us pick a replacement and installed it the same day."

A failing water heater isn't just inconvenient — it can be a safety risk. Watch for these warning signs and call us before it gets dangerous.
Report Your IssueThis means current is leaking to earth — usually through a damaged heating element. Using the heater in this state is an electrocution risk. Stop using it and call a plumber.
Fix immediately — electrocution riskLeaks from the body of the heater can indicate a corroded internal tank (storage type) or failed gaskets. Water near electrical connections is extremely dangerous.
Fix urgently — electrical hazardHot one second, cold the next. This is typically a failing thermostat or a flow sensor that can't regulate properly. The heater is working but can't maintain a stable temperature.
Fix soon — comfort and safety issueBrown or reddish hot water means the internal tank or anode rod has corroded. The heater may still work but the tank is deteriorating and could start leaking soon.
Service soon — tank corrodingA heater that used to get hot in seconds now takes minutes. Limescale buildup on the heating element acts as insulation, reducing efficiency and increasing electricity usage.
Service soon — wasting electricityWe believe in honest pricing. Here's how it works.
Repair cost depends on the heater type, the faulty component, and whether parts need to be ordered. The price we quote includes parts and labour — no surprise add-ons. A simple thermostat or element replacement is straightforward. If the repair cost approaches the price of a new unit, we'll recommend replacement instead.
