An instant water heater gives you hot water on demand without a storage tank — a popular choice for compact HDB and condo bathrooms. SparkFlow supplies electric instant heaters from Champs, Rubine, Ariston, Mistral, KDK, 707 and more, starting from around $98. As a home-services contractor, we install them properly: mounting the unit, connecting it to your isolator and water supply, and testing the safety cut-out.

Electric Instant Water Heater — common questions
- Do you install instant water heaters, and who handles the electrical work?
- Yes. We quote mounting, plumbing and electrical connection as separate parts of one scope. Any new or altered fixed wiring is handled by an EMA Licensed Electrical Worker, whose role can be identified in the quote.
- Which brands do you carry?
- Our instant heaters come from Champs, Rubine, Ariston, Mistral, KDK, 707, Decco, NNIO, Toshiba and Europace. Prices range from about $98 up to roughly $549 depending on wattage and features like pump assist.
- Should I get an instant or storage water heater?
- Instant heaters heat water as it flows, so there's no tank and no waiting — ideal for single-shower bathrooms and tight spaces. If you need strong flow at multiple outlets at once, a storage heater may suit better. We're happy to advise based on your bathroom.
- Can you replace my old water heater?
- Yes, swap-outs are common. We remove the old unit, check the existing wiring and water points are sound, and install the new heater. If the isolator or piping needs updating, we'll flag that in the quote.
- How much does an instant water heater cost installed?
- The heater itself runs from around $98 to $549. Installation is quoted on top based on whether it's a straight replacement or a new point, and the condition of your existing wiring and plumbing.
