Replacing like for like is usually simpler than changing from instant to storage, or the other way round.
A new location may need connections that are not there yet.
Whether the current heater point, switch and water connections suit the new heater.
Larger storage tanks need more space, stronger support and suitable piping.
Wall, ceiling and false-ceiling positions each have different requirements.
Tight spaces, height and access openings affect how the work is carried out.
Electrical, plumbing, access and making-good works are quoted separately where needed.
Taking down and disposing of the old heater are separate charges.
Compare heater types
Both types are common in Singapore homes. The better choice depends on your bathrooms, space and how your household uses hot water.
| Consideration | Instant heater | Storage heater |
|---|---|---|
| Typical application | A single shower or bathroom outlet | One or more outlets, depending on capacity and piping |
| Hot water availability | Heats water as it flows; no stored hot water | Supplies stored hot water; needs time to reheat after use |
| Number of outlets | Usually one heater per shower or bathroom | Can serve several outlets when sized and piped for them |
| Space requirements | Compact wall-mounted unit | Larger tank needing a suitable wall or ceiling location |
| Installation considerations | A suitable heater point and water connections at the shower | Support for the full tank weight, piping to each outlet and maintenance access |
| Household usage | Suits individual showers and smaller households | Suits households wanting hot water at several outlets |
| General energy considerations | Uses power while heating the water being used | Uses power to heat and keep stored water hot; insulation and settings matter |
Actual performance and running costs depend on the model, capacity, water pressure and household habits. Check the manufacturer's specifications for the heaters you are considering.
Before installation
A quick check of the location and existing connections helps confirm the right heater and an accurate quotation.
The wall or ceiling must be able to take the fixings and the heater's weight.
A filled storage tank weighs far more than an empty one, so its support must suit the full weight.
Heaters need a suitable dedicated heater point and switch for the model. Plug sockets and extension cords are not suitable.
The cold inlet and hot outlet must suit the heater. Storage heaters may need piping to each outlet they serve.
Controls, valves and the unit should remain reachable. Heaters above false ceilings need a suitable access opening.
The heater must fit the space with sensible clearance from the ceiling, fittings and shower.
Electric water heaters sold in Singapore must carry the SAFETY Mark. Customer-supplied heaters should be new, undamaged and complete with the manufacturer's mounting kit and instructions.
Photos allow an initial review. Some locations, especially ceilings and storage tanks, need a site visit before quoting.
Choose instant, storage or not sure, and whether you need installation only or supply and installation.
Share the location, existing heater, electrical point and water connections through WhatsApp.
We quote the installation and list any removal, disposal, fittings or additional works separately.
Confirm the agreed scope and arrange a suitable installation appointment.
Installation dates are arranged after the scope is confirmed and depend on availability.
