Out with the old. Hot by tonight.

Storage tanks last 7–10 years in Singapore. Past 8, every breakdown is a roll of the dice — fix once, the next failure follows soon. Replacing proactively beats waiting for a 5am flood.

If today's quote is more than 50% of a new mid-spec unit ($400ish), replacing is the better call. We tell you the maths honestly during diagnosis.

Either the tank's gone smaller (sediment buildup) or the element can't keep up. New 30L lasts ~25 minutes for two people; if you're already running cold after 10, time to upgrade or resize.

Visible reddish tint when you first turn it on = the inner lining of the tank is failing. There's no "fix" — corrosion only goes one way. Replace before it leaks through.

Aging element develops partial earth leaks. Tripping today, tripping more next month, full short-circuit one cold morning. Element replacement is one fix; a whole new heater with a fresh element is sometimes the smarter call.

Modern units are 15–25% more efficient than 10-year-old ones, support Wi-Fi scheduling, and the better tanks (Ariston, Rheem) come with 5–7 year warranties. Sometimes the upgrade is the reason.
