To my rescue was Saravanan Muthu from Homeone Water Heater Pte Ltd. All thanks to the shabby work of my interior designer's lousy excuse of an electrician whom tapped the wires from my heater for plug routing causing it to overload and burn (see photos). The pros from Homeone came and did a diagnosis and immediately pin pointed the issue. Thank goodness for them and their turnaround was amazingly fast. Need someone professional in water heaters, these guys are the people you should call. Kudos.

Plumbers Hasan & Tamal did a fantastic job on removing my old storage tank and fixing up with the new one! To top it off, it was even installed below the false ceiling! Don’t ask me why, this was installed by the previous owner and I’m assuming he hired a Non-PUB Certified Plumber thus such a job was made.

So instead of saying they can’t get the job done, they came up with a plan and reported back to their supervisor on what needs to be done in order to get the new storage tank installed. So after much consideration, we decided to proceed with the plan.

I was extremely impressed with the professionalism and ease of communication with the folks at Homeone from the very first contact.

From the first enquiry with Mr Eng, his response was very prompt and timely. He was incredibly helpful in providing an accurate quote based on my needs. The quotation and work scope was clear and not additional questions needs to be asked. A time for the work was immediately scheduled.

Great experience with Technician, Mr Dharma. He came on time and single handedly completed the replacement of our old heater with a new one while explaining to us the deficiencies that we had with our previous heater installation in 2018. He did his job swiftly and extremely well, the sales team at Homeone Euro was great as well explaining the issues clearly on WhatsApp.

Unlicensed water heater replacements

Water heater explosion

An unlicensed handyman installed a storage water heater in a Cote D’Azur apartment in Marine Parade, resulting in an explosion on Saturday (Sept 30, 2022). The explosion was caused by a choked drainpipe and shattered the glass.

Taking a shortcut

A handyman improperly installed the water heater hook to save time or due to a lack of proper parts, causing the tank to fall when the hook corroded.

Faulty Electrical Connection

A typical mistake made by handymen is using a 13A socket outlet as the connection point between the water heater and power supply

Don’t risk unsafe installation.

Replace your water heater with confidence — PUB-licensed plumbing oversight and EMA-certified electrical supervision.

Our trained technicians perform the work to Singapore standards.

Water Heater Replacement in Singapore (Ariston)

Sharif and Muthu were very experienced and thorough with the uninstallation of our Viessman shortage heater (which died just after 1 year) and installation of Ariston storage heater. Also appreciate Bryan’s prompt support and quick delivery of the storage heater after a last minute change. The team was also quick to spot that there were missing components from the first installation (from a different installer) and quick to rectify the issues. Will definitely recommend Homeone!

Common Questions About Water Heater Replacement in Singapore

Quick answers about water heater replacement for HDB, condo, and landed homes in Singapore — including compliance, safety.

How much does water heater replacement cost in Singapore?

Pricing depends on the heater type (storage vs gas), capacity (e.g., 15L/25L/40L+), installation condition, and whether new safety components are required (e.g., valves, piping, electrical bonding). Share a photo of your current heater and installation area and we can advise the suitable replacement option.

Do I need a PUB Licensed Plumber for water heater replacement?

If the job involves plumbing works (pipes, valves, discharge line, etc.), it should be done properly under a PUB Licensed Plumber to ensure compliance and safety. This also helps reduce risk of leaks and protects warranty and insurance claims.

How long does water heater replacement take?

Most replacements take about 2-3 hours, depending on accessibility (bathroom ceiling/inside cabinet), whether the old heater is stuck/rusted, and if additional rectification is needed (valves, piping, wiring, bonding).

What are signs I should replace (not repair) my water heater?
  • Tank is leaking, rusty, or swollen
  • No hot water or heating is unstable
  • Frequent tripping / burning smell / visible damage
  • Water is brownish or has metallic smell
  • Heater is very old and parts are not reliable

For safety, we usually recommend replacement when the tank has leakage/corrosion, as this can worsen suddenly.

Can you replace my old brand with another brand (e.g., Joven → Rheem)?

Yes — as long as the capacity and installation requirements match (mounting space, inlet/outlet position, electrical load, and safety components). We’ll recommend compatible options after reviewing your current setup photos.

Do you replace water heaters for HDB, condo, and landed properties?

Yes. We handle replacements across HDB, condo, and landed homes. The installation approach may differ depending on location (service yard/bathroom), ceiling access, and existing pipe routing.

Will you dispose of my old water heater?

Yes, we can remove and dispose of the old unit after replacement. If the unit is larger/heavier (e.g., 50L and above), additional handling may be required due to safety and manpower.

Do you provide warranty for the replacement?

We provide 1 Year Engineering Warranty (Homeone). Manufacturer warranty depends on the brand/model. Our installation is done professionally with proper safety checks, and we’ll advise the warranty terms for the selected heater. Keep your invoice and warranty card (if provided).

How do I get a fast quotation for water heater replacement?

Send us 3 items: (1) your name, (2) property type + location, and (3) photos/video of the existing heater and installation area. We’ll recommend suitable replacement options quickly.

Tip: For best accuracy, include a short video showing the heater, valves, and surrounding space.
