Water Heater Installation FAQs

StringsSG water heater jobs start from $124.20. Replacing an instant heater costs less than a storage heater, and adding a 20A heater point is listed separately. Every price is in the table on this page and is fixed before you book.
A heater that trips the breaker usually has a failed heating element, water inside the electrical housing, or a faulty switch or point. Stop using it and book a repair, because the fault is on a circuit that also involves water.
Instant heaters are compact and heat water as it flows, which suits most HDB bathrooms with one shower. Storage heaters hold a tank of hot water, which suits households that need hot water at several taps or run a rain shower.
A water heater should run on its own correctly rated point. If your bathroom does not have one, or you are changing from instant to storage, add a 20A water heater point to the booking.
