Water heater installation
Electric Storage Water Heater — common questions
- Do you install storage water heaters?
- Yes. Installation can include mounting, plumbing and electrical connection, itemised on top of the heater price. Any new or altered fixed wiring is handled by an EMA Licensed Electrical Worker.
- Which storage heater brands and sizes do you carry?
- We stock Ariston, Rubine, 707, Mistral, KDK, Champs and Ferroli, in common tank sizes such as 15L and 20L. Larger tanks suit homes that want more continuous hot water for baths.
- How much is a storage water heater?
- Storage heaters start from about $239 and go up to roughly $550 depending on brand and tank size. Each listing shows its price; installation is a separate WhatsApp quote based on your setup.
- Should I choose a storage heater or an instant one?
- Storage heaters hold a tank of pre-heated water, which is great for filling a bath or multiple back-to-back showers. Instant heaters heat on demand and save space. If you're deciding, tell us your usage on WhatsApp and we'll recommend the right type.
- Can you install in an HDB flat?
- Yes. Storage heaters are common in HDB and condo bathrooms, and our licensed team handles the mounting, wiring and water connections to code. Just share your bathroom layout so we can confirm tank size and placement.
