Water heater installation in Singapore involves both electrical and plumbing work.

## How to choose
- Decide between instant and storage heaters: instant heaters suit single bathrooms, while storage heaters serve multiple outlets and rain showers better.
- Check that the electrician will install the heater on its own circuit with the correct isolator and that your RCCB is working.
- Ask whether the quote includes removal of the old heater, new piping and fittings.
- For storage heaters, confirm the wall can bear the weight and that the bracket is fixed properly.

## Red flags
- Installers who skip the earth connection or bypass the RCCB.
- No licensed worker for new wiring or pipe rerouting.
- Recommending replacement without testing the heating element or thermostat.

## FAQs
### Who can install a water heater in Singapore?
Electrical connections such as a new power point or wiring must be done by an EMA Licensed Electrical Worker. New water pipe work must be done by a PUB Licensed Plumber. PUB lists replacing the pipe between a stop valve and an instantaneous water heater as simple work that can be done without a plumbing licence.

### How much does it cost to install a water heater?
Electricians typically charge about $100–$150 for the electrical installation or replacement of a water heater, excluding the unit itself. Storage heaters with new piping cost more. Ask for a quote that covers the unit, labour, piping, removal of the old heater and transport.

### Why is my water heater tripping the power?
A heater that trips the RCCB may have a faulty heating element, water ingress or a wiring problem. Switch it off at the isolator and stop using it, then call a licensed electrician to test it. Do not bypass the RCCB, which is there to protect against electric shock in wet areas.
