A failed water heater never picks a convenient morning. The good news: in Singapore, replacing one is fast and surprisingly affordable — if you know what installation should cost and what's included. This guide covers 2026 installation and replacement prices for both instant and storage water heaters, what "basic installation" actually includes, and how to get it done as soon as tomorrow.
Water heater installation prices in Singapore (2026)
| Service | Typical price |
|---|---|
| Instant water heater — basic installation (replace existing unit) | from $60 |
| Storage water heater — replacement (same position, existing power & water points) | from $150 |
| Storage water heater — new installation (new point) | from $250 |
| Relocation, concealed piping, false-ceiling access or other complex works | quoted on request |
Tip: if you buy the heater and installation together, many of our listings offer a bundled "with installation" variant that works out cheaper than booking the two separately — check the options on each product page.
What's included in a basic installation
- Dismantling and disposal of your old water heater
- Installation of the new unit at the existing electrical and water points
- Connection, leak check and full working test before the installer leaves
What's not included: running new wiring or piping, relocating the heater to a different spot, and major false-ceiling works. Those are doable — they're just quoted separately after we see photos of your setup.
Instant or storage — which should you install?
Short version: instant heaters suit single bathrooms and smaller households; storage heaters give stronger, more stable hot water for families and rain showers. We've written a full comparison in our Instant vs Storage Water Heater guide if you're still deciding.
5 signs your water heater is due for replacement
- It's more than 8–10 years old (storage tanks corrode from the inside out)
- Water comes out rust-tinted or smells metallic
- Your ELCB/circuit breaker trips when the heater runs — see our water heater safety guide for why this matters
- Lukewarm water even at maximum setting
- Visible dripping or pooling under the tank

FAQ
Can you install a water heater I bought somewhere else?
Yes. Our installation service is bookable on its own — you don't need to have bought the heater from us (though it's cheaper bundled).
How long does a replacement take?
45–60 minutes for a like-for-like swap at existing points.
Do you take away the old heater?
Yes — dismantling and disposal of the old unit is part of basic installation.
