AI image by LocalRankChoosing a water heater in Singapore usually comes down to two formats, a compact instant (tankless) unit or a storage tank, and the right supplier can advise, sell and fit the model that suits your bathroom and wiring. The ten companies below all supply or install water heaters here and set out their brands, services and terms on their own websites. Treat it as a shortlist to compare, not a ranking.
1. Water Heater City
Water Heater City is a dedicated water heater supply-and-install service covering storage, instant and multipoint units, and it also replaces ageing heaters. Its site lists a wide brand range, including Ariston, Rheem, Joven, Rubine, 707, Champs, Mistral and Viessmann. The company says the work is carried out by PUB-licensed plumbers and backed by a one-year workmanship warranty.
2. Homeone
Homeone (Homeone Water Heater Pte Ltd) provides one-stop supply, installation and replacement of storage water heaters, plus gas heater replacement. It states it fits storage brands such as Rheem, Joven and Ariston and gas units from Paloma, Macro and Rinnai, with jobs supervised by a PUB-licensed plumber and, where needed, EMA-licensed gas and electrical workers. The company advertises a one-year workmanship warranty on top of the manufacturer's cover.

Everyhome.SG is an online home and bathroom supply store that both sells water heaters and offers an installation or replacement service for instant and storage models.

Warranty terms come from each heater's manufacturer rather than being stated by Everyhome itself.
5. Fixwerks
Fixwerks, through its Waterwerks arm, repairs storage and instant water heaters and offers replacement and installation when a unit is beyond repair. It says its technicians are experienced across brands including Joven and Ariston, and frames its work around repair and maintenance to safety standards. The company lists workshops in Serangoon North and Tampines.
6. Nation Electric
Nation Electric supplies and installs both storage and instant water heaters, and for replacements will supply the new unit, remove the old one and fit the replacement. It presents heater fitting as part of its electrical-services work and describes its installers as experienced plumbers.

8. 707
707 is a home-grown Singapore water heater brand, run by Cheong Hock Guan Water Heater Centre, that says it has been in local homes since 1978 and makes both instant and storage models. It states its heaters carry Singapore's 4-tick energy-efficiency rating and are sold through its official online shop and authorised retailers, with installation to be done by a Licensed Electrical Worker. The brand publishes tank warranties of five years on instant units and seven years on storage units, with two-year parts and service cover.
9. Rheem Singapore
Rheem is a long-established water heating manufacturer whose Singapore site lists electric storage and electric instant (tankless) heaters for homes, alongside commercial heat-pump, solar and gas systems. It directs buyers to authorised retailers via a dealer locator and to its official Lazada and Shopee stores, and offers warranty registration for its equipment. The company describes nearly a century of experience in water heating.
10. Joven Electric (Singapore)
Joven Electric (Singapore) is the local presence of the Joven brand, offering electric storage and instant water heaters, plus water purifiers, through a network of authorised dealers rather than direct installation. It states a warranty of two years on components and five years against tank leaks. The company bills Joven as a long-running Malaysian water heater brand sold widely across the region.
How to choose
- Decide between an instant (tankless) heater and a storage tank first. Instant units heat water on demand and save space, which suits smaller bathrooms and single-point use, while a storage tank holds a reserve of hot water that copes better when several outlets or a rain shower run at once. Match the format to how many bathrooms and people the heater must serve.
- Insist that installation is done by the right licensed tradesperson. Water heater fitting in Singapore involves a dedicated electrical circuit and, for tank units, plumbing connections, so look for a supplier who works with a PUB-licensed plumber and/or a Licensed Electrical Worker, and check any HDB or condominium requirements before booking.
- Read the warranty carefully and get it in writing. Tanks, parts and labour are often covered for different periods, so separate the manufacturer's tank warranty from the installer's workmanship warranty, and confirm you register the unit with the brand to keep its cover valid.
- Confirm the full scope in one quotation. A replacement should state whether removing and disposing of the old heater, any pipe or wiring adjustments, and testing are included, so you are not surprised by add-ons; ask too whether genuine brand parts are used.
- Size and position the unit to your home. Check the heater's capacity or flow rate against your usage, that the wall and space can take the model, and that the mounting point suits either a single bathroom (single-point) or several outlets (multipoint), rather than choosing on brand name alone.
