Which heater you actually have
The price changes with the tank location, not the brand sticker. A tank above plasterboard is a ceiling job. A tank on the service-yard wall is not.

The circuit the heater needs
Plan Condo concealed storage heaters and HDB instant or tank swaps
Isolate the stopcock or the heater switch before any fitting is loosened.
Photograph the existing joint so the replacement can match the thread and the outlet.
Do the repair on the existing point. Do not chase a new pipe unless a licensed plumber is on the job.
Run water, check the ceiling below if the bathroom is over another room, and wipe the joint dry.

| Access | HDB | Condo | Landed |
|---|---|---|---|
| Approval | Town Council hours for noisy work. An HDB permit only if the layout or a hack changes. | MCST by-laws, a water-shutdown window, and a deposit if the by-law asks for one. | No HDB permit. A new sewer run or a structural chase is still PUB or BCA, not a handyman visit. |
| Water | Like-for-like on the existing outlet stays maintenance. | The same rule, plus the building may shut the riser for a short window. | Long runs, pumps and tanks need the plumber to see the plant, not only the tap. |
| Access | Service yard and bathroom are usually reachable the same day. | Lift booking and protection of common areas come first. | A roof, a gutter or an external pipe may need safe access before anyone climbs. |
- Photo of the leaking joint and the brand mark
- Say if the water can be isolated from inside the flat
- Clear the cabinet under the sink
- Mention a condo shutdown or an HDB hacking rule if you already know it
- Keep children and pets out of the wet area during the visit
Frequently Asked Questions
How much does a concealed ceiling storage heater cost to replace in a condo?
A 30L to 80L Joven, Ariston or Rheem turnkey swap is S$580 to S$1,350. That includes the plasterboard opening, a 450x450mm or 600x600mm aluminium hatch, PUB valves, braided hoses, drain reconnection and a 20A switch check.
Why do brand installers refuse concealed ceiling heaters?
The replacement tank often will not pass the original hole, and the brand crew does not cut plasterboard. The ceiling opening and hatch are part of this visit.
Does a storage heater need a licensed plumber?
The pressure-relief and check-valve arrangement follows PUB rules. Reconnecting the existing points is maintenance. A new or relocated supply pipe is a PUB Licensed Plumber. Homey Furnishing Pte. Ltd. UEN is 202018148K.
