Instant Water Heater Replacement & Installation Singapore
About FixMove — FixMove Singapore supplies and installs instant water heaters (Rheem, Joven, Ariston, 707 and Mistral) with plumbing and regulated electrical scope identified before booking. Install-only and supply responsibility are confirmed for the selected model and site.
Need an instant water heater installation in Singapore — a fresh fit-out, a like-for-like swap, or an upgrade with a rain shower? The written scope separates plumbing connections from any dedicated power-point work, then states the agreed testing and handover checks.
Quick answer: instant water heater installation in Singapore
FixMove installs and replaces instant water heaters for HDB, condo and landed bathrooms. Install-only work starts from S$120 when you supply the unit; supply-and-install packages are usually S$220-S$450. Plumbing and electrical scope are checked before quoting, and the heater is leak- and heat-tested before handover.
A S$10 fuel surcharge applies to every visit. No additional standard call-out or inspection fee applies. Urgent service or a customer-requested appointment time adds one S$30 fee, subject to technician availability and confirmation. The S$30 is a separate service fee. Pricing terms.

Instant or storage — which to install?
An instant water heater heats on demand, so there's no tank standby loss — ideal for a single bathroom or point-of-use needs, and it frees up ceiling space. A storage heater holds a tank of hot water and suits homes running several outlets at once. If you're choosing between them, send us your bathroom count, power supply and how the hot water is used and we'll recommend the right unit and size — and handle the full water heater replacement either way.
