FAQ

Water Heater Installation & Repair: Frequently Asked Questions

How much does water heater installation cost in Singapore?

The cost depends on the type of heater, its capacity, whether existing pipes and wiring can be reused, and access to the installation point. We confirm the full scope and price before any work starts.

Should I choose a storage or instant water heater?

Storage heaters suit homes that need hot water at several points, such as a kitchen and multiple bathrooms. Instant heaters suit single shower points and save space. We can recommend an option after checking your bathroom layout and electrical supply.

Why is my water heater leaking?

Common causes are a faulty pressure relief valve, loose pipe fittings or a corroded tank. Valve and fitting leaks can usually be repaired, while a leaking tank normally needs replacement.

Why does my water heater keep tripping the power?

Tripping is often caused by a faulty heating element, moisture in the wiring or a failing isolator. Switch off the heater and contact us, as this is an electrical safety issue.

Can you install the water heater and electrical supply together?

Yes. MM Engineering Works is an EMA-licensed electrical contractor, so we can handle the plumbing connections and the electrical supply in the same visit.
