Professional Plumbing Services in Singapore
At RSF Waterproofing, we install instant and storage water heaters for everyday residential use.
Our work focuses on correct mounting, safe electrical and plumbing connections, and leaving the bathroom clean once the job is done. We have years of experience in providing water heater installation services in Singapore, installing water heaters across HDBs and condos every week.
Comprehensive Water Heater Installation for HDB, Condo & Landed Homes
Most of our installation work comes from HDB flats, followed by condominiums and landed homes.
We handle both instant and storage water heater installations, including replacements and upgrades. New installations are assessed more carefully, as existing wiring and piping are not always positioned where they appear to be.

Instant vs Storage Water Heaters: Which One Is Right for You
Both instant and storage water heaters are widely used in Singapore, and the best one for you would depend on your usage of hot water.
- Instant water heaters are preferred in smaller bathrooms as they not only save space but also heat water only when you need it. We install them frequently in HDB flats, especially where ceiling mounting is not practical.
- Storage heaters work better for families or homes with heavier daily usage. They support longer showers and multiple bathrooms, but ceiling mounting and structural support must be checked properly.
Our Water Heater Installation Process
- Site assessment – We check your existing setup, space, and connection points.
- Clear quotation – You receive an upfront quote based on the actual scope of work.
- Installation – Our licensed technicians install the heater securely and correctly. In case of replacement, they will carry out all effective measures to replace the old one and remove it properly.
- Testing and handover – The unit is tested, and the area is cleaned before completion.
What’s Included in Our Installation Service
Our water heater installation service includes the essential work needed for a safe and proper setup:
- Removal of the existing water heater, if applicable

We focus on carrying out the work required for a safe and stable installation. If there is any additional work that needs to be done based on site conditions, we will discuss it during the assessment instead of adding it later without discussion.

Frequently Asked Questions About Water Heater Installation
Yes. Proper installation matters more than many homeowners realise. We’ve seen heaters fail not because of the unit itself, but due to incorrect wiring or weak mounting done years earlier, which can lead to safety issues and warranty problems.
Instant water heaters heat water only when you turn on the tap. They are ideal for small families or small spaces. Storage water heaters hold a tank of hot water and are best suited for larger families or when there are many showers taken daily.
Both can be employed in HDB flats. Instant heaters consume less space, but storage heaters require sufficient ceiling height and a proper installation point.
Standard installations usually take a few hours. Simple replacements will take less time, while installations involving storage heaters or those that need adjustments may take longer. Your installer can give you an estimate of the time required for the installation.
The final cost will depend on a number of factors, including the type of water heater, the complexity of the installation, whether plumbing or electrical connections are required, and whether it is a replacement installation or a new installation.
Yes. Without proper installation, the warranty could be nullified, and potential dangers could arise. Proper installation is done according to the manufacturer’s guidelines.
You should replace it if it leaks, if it no longer provides a steady supply of hot water, if it takes too long to heat, or if it looks worn out. Sometimes, old units that frequently break down may be more economical to replace.
It is important to check the water heater for leaks, unusual sounds, or changes in water temperature. Regular servicing of the water heater can increase its lifespan.
