PS Home Maintenance Pte Ltd
PS Home Maintenance operates out of Parc Rosewood and has built a name for handling the kind of installations where cutting corners is not an option. They work with both storage and instant models from the usual trusted brands, and they do repairs and custom fittings too.
The thing that makes them worth the call is that they do not just mount the unit and leave. Their team checks your existing wiring, confirms the earthing is sound, and makes sure the setup meets current PUB standards. If you live in an older flat where the original wiring is a bit suss, that extra diligence matters.
They also build in energy-saving adjustments so your bill does not spike after the new heater goes in. Daily operating hours run 8am to 10pm, which covers most scheduling headaches.
Address: 77 Rosewood Dr, #03-40 Parc Rosewood, Singapore 737786
Phone: +65 6854 4958
Hours: Daily, 8am – 10pm
Website: PS Home Maintenance Pte Ltd
Ideal if you want a crew that treats a water heater install like a proper electrical job, not a quick handyman fix. Also a good pick for landed homes where the pipe runs are longer and the setup less standard.
LS Handyman Service Singapore
LS Handyman covers both residential and commercial jobs from their Sims Drive base. They do the full spread: thermostat tweaks, full system replacements, and installation of higher-end models that need a bit more care during setup.
What sets them apart is their diagnostic step. Before they quote you, they actually trace the problem rather than guessing. If your old heater is tripping the breaker, they will tell you whether it is the heater, the switch, or the wiring in the wall—then give you a price for exactly what needs doing.
None of these are sponsored placements. If you belong on this list, tell us what you do.
Address: 45 Sims Dr, #12-152, Singapore 380045
Phone: +65 6854 4992
Hours: Daily, 8am – 8pm
Website: LS Handyman Service Singapore
A practical choice if your water heater problem is not straightforward and you want someone who diagnoses before they start unscrewing things. Their 8pm closing time is earlier than some others, so book ahead rather than calling last-minute.
Local Service Pte Ltd
Local Service runs from Ang Mo Kio and leans hard into tech—they have their own booking app so you can schedule, track the job, and pull up past service records without digging through WhatsApp messages. For anyone who has lost a plumber’s contact halfway through a reno, that alone is a small blessing.
They install water heaters for homes and commercial spaces, but they also handle retrofit work in older properties where the pipe layout is less forgiving. Their team is trained in eco-friendly practices, and they aim for quick turnaround without leaving a mess behind.
If you have ever waited around for a contractor who gave a four-hour window and showed up at the tail end, Local Service’s app-based tracking takes some of the guesswork out.
Address: Block 631, Ang Mo Kio Avenue 4, #11-908, Singapore 560631
Phone: +65 6797 0750
Hours: Daily, 8am – 10pm
Website: Local Service Pte Ltd
Good for the kind of homeowner who likes to track things digitally and keep a clean service history. Also a strong option for conservation shophouses or older condos where the install needs finesse.
Affordable Services Pte Ltd
Despite the name, Affordable Services is not about bare-minimum work. They put their energy into energy-efficient heater installations and offer maintenance plans that extend the life of your unit. They also use greener materials in their repairs and setups.
Their approach is educational—they will walk you through why your old heater failed, what the new one does differently, and how to keep it running well. If you are the sort who likes to understand what you are paying for, that transparency is genuinely useful.
They close at 6pm, which is the earliest on this list, so weekday availability matters. Plan your booking accordingly.
Phone: +65 6432 8466
Hours: Daily, 8am – 6pm
Website: Affordable Services Pte Ltd
Suits someone who wants the long-term picture—not just a working heater today, but lower electricity bills and fewer repairs over the next five years. Also a fit if you prefer a company that explains things plainly.
While your water heater is getting sorted, you might also want to look at Pest Control Services in Singapore—a dry home with warm pipes is one thing, but a pest-free one is real peace of mind.
Water Heater City
Water Heater City has been at this for over ten years and holds a PUB licence (WS17962021) plus BCA certification. They are an official partner for Ariston, Rheem, and Joven, so if you are buying one of those brands, they handle supply and installation in one go—with the warranty properly validated.
Their installers can work around false ceilings and other built-in finishes, which matters a lot in newer condos where the heater sits above a plasterboard panel. A sloppy cut there and you are looking at a patch-up job on your ceiling. Their team knows to avoid that.
They also do PUB-approved setups, meaning the paperwork is sorted for compliance. Open daily 8am to 10pm, with a WhatsApp line (+65 8241 0032) for quicker quotes.
Phone: +65 6797 8775
WhatsApp: +65 8241 0032
Hours: Daily, 8am – 10pm
Website: Water Heater City
The pick if you want brand-authorised installation with all the compliance boxes ticked, especially for storage heaters where proper mounting and pipe connections are non-negotiable.
SG1 Plumber
SG1 Plumber has been running since 2015 from their Trivex office. They do storage and instant water heaters, and they offer next-day service on most bookings—useful when your old unit has given up midweek and the family is not keen on cold showers.
After the install, they follow up to check everything is running properly. That post-job call is not something every service bothers with, and it catches small issues before they become callbacks. Their hours stretch from 9am to 10pm daily.
Address: 8 Burn Road, #15-13 Trivex, Singapore 369977
Phone: +65 9061 0797
Hours: Daily, 9am – 10pm
Website: SG1 Plumber
Suits the homeowner who wants the job done fast—next-day where possible—and appreciates a follow-up rather than a vanish-after-payment approach. Also well set up for commercial units like offices or shop spaces.
None of these are sponsored placements. If you belong on this list, tell us what you do.
Mr Plumber Singapore
Mr Plumber Singapore has clocked over a decade in the trade and works out of Lower Delta Road. They handle water heater installs for both homes and commercial spaces, covering storage and instant models. Their pricing is upfront—no hidden charges creeping in after the job.
They are known for working clean and fast. One installation was reportedly completed start-to-finish in 25 minutes, with the work area tidied up before they left. That kind of speed only comes from doing the same job thousands of times, and it means less disruption if you are working from home.
Their plumbing scope goes wider than just heaters, so if you have a leaking tap or a choked drain alongside the install, they can sort it in one visit.
Address: 1090 Lower Delta Rd, #03-07A, Singapore 169201

A steady choice when you want a straightforward price, quick work, and the option to bundle a few other plumbing fixes into the same call-out.
Wong Plumber
Wong Plumber operates 24/7 from Jalan Bukit Merah, and that round-the-clock availability is the headline here. Heater gone at 2am before an early flight? They will take the call.
Beyond water heater installation and repair, they also handle toilet and sink work, so they are set up for the late-night plumbing disasters that never seem to happen during office hours. Their team is known for thorough cleanup after the job—no leftover cable offcuts or dust rings on the bathroom floor.
Address: 28 Jalan Bukit Merah, Singapore 152028
Phone: +65 8338 6737
Hours: Open 24/7
Website: Wong Plumber
The obvious pick for emergencies. Even if your situation is not urgent, the 24-hour line means you can book around shift work or odd schedules without having to take leave. Also a handy number to save in your phone just in case.
Once the heater is sorted, you might find yourself with a free evening—have a look at our guide to Pizza Delivery Services in Singapore for a reward after a long day of home repairs.
How to choose
Start with the heater type. Instant heaters are simpler to install and cheaper to run for small households. Storage heaters need a dedicated power point and solid wall mounting, so the installer’s electrical knowledge matters more. If you are replacing an old storage unit with a new one, check whether the existing pipe points and bracket positions match—some services include minor pipe adjustments, others charge extra.
Ask about PUB compliance. Any installation that involves electrical work in a wet area must meet Singapore’s safety standards. A proper installer will test the earthing and give you documentation. Services like Water Heater City and PS Home Maintenance make this part of their standard process.
Price is not always apples-to-apples. One quote might include disposal of the old unit, false-ceiling patching, and a warranty check; another might price those separately. Get a breakdown. A fair range for a straightforward instant-heater replacement with installation sits roughly between $80 and $180; a full storage-heater supply-and-install can run from $300 upward depending on the brand and model.
Response time matters if your only bathroom is out of action. SG1 Plumber and LS Handyman are known for next-day bookings. Wong Plumber’s 24/7 line is there for the genuinely urgent jobs. If you can wait a few days, you have more choices.
Finally, think about what else needs fixing. Mr Plumber Singapore and Wong Plumber both handle general plumbing, so if your tap has been dripping for weeks, you can knock it all out in one visit.

Frequently asked questions
How much does water heater installation cost in Singapore?
For a basic instant water heater replacement with installation, expect roughly $80 to $180. A full storage heater supply-and-install typically starts around $300 and goes up depending on the brand and model. Always get a breakdown of what is included—disposal of the old unit, minor pipe adjustments and warranty registration can be extras.
Do I need a PUB-licensed installer for my water heater?
Yes, if the job involves electrical connections in a wet area like a bathroom. A PUB-licensed installer ensures the work meets Singapore’s safety standards and provides the necessary compliance documentation. Water Heater City is one example of a PUB-licensed service on this list.
What is the difference between an instant and a storage water heater?
Instant heaters heat water on demand and are smaller, wall-mounted units suited to HDB flats and low-usage households. Storage heaters hold a tank of hot water, need a dedicated power point and stronger wall support, but deliver higher water pressure—better for larger homes with multiple bathrooms.
Can the same plumber fix my leaking tap and install the water heater?
Several services handle general plumbing alongside heater installation. Mr Plumber Singapore and Wong Plumber both do toilet repairs, sink fixes and drain clearing, so you can bundle jobs into a single visit and save on call-out fees.
How quickly can I get a water heater installed in an emergency?
Wong Plumber operates 24/7 and can attend to urgent calls at any hour. SG1 Plumber offers next-day service on most bookings. If it is not an emergency, most services can schedule you within one to two days.
Should I buy my own water heater or let the installer supply it?
If the installer is a brand-authorised partner, like Water Heater City for Ariston, Rheem and Joven, letting them supply the unit often means the warranty is validated on the spot and any faulty-unit issues are handled directly. If you buy your own, confirm the installer will still honour their workmanship warranty.
