Crib Point is a working Western Port town south of Hastings, with a settled residential core of mostly postwar and 1960s and 70s housing and the port and naval base nearby. It is a year-round suburb with practical, year-round demand. Mornington Hot Water is a free referral service. We connect you with licensed hot water plumbers who cover Crib Point. We are not a plumbing business ourselves, and the referral costs you nothing.
Old tanks and daily load
Electric storage is the dominant system, a large share of it on controlled-load tariffs and a large share of it approaching or past the usual 8 to 12 year life. Full-time family households work those systems hard, so elements, thermostats and relief valves wear out on schedule rather than early.
Sediment is a common finding in older tanks here. It reduces the usable hot water in a tank that is otherwise sound, which presents as a system that runs out faster than it used to rather than one that fails outright.
For a full-time household, the running cost case for a heat pump is at its strongest, because the saving applies every day of the year. It is worth getting quoted alongside a like-for-like swap rather than instead of it.
Repair it or replace it
If the tank itself is leaking, it is a replacement. Elements, thermostats and relief valves on a younger tank are often worth fixing, with repairs roughly $150 to $600 depending on the part. See hot water repairs and hot water replacement.
As a guide, electric storage like-for-like swaps run from around $800 to $2,500 installed. Gas storage and continuous flow sit around $1,200 to $3,500, and a heat pump $3,000 to $6,000 before incentives. The cost guide has the detail.
Same-day replacement is often possible for common tank sizes when you get in touch in the morning.
Frequently asked questions
Our hot water runs out faster than it used to. Why?
Usually sediment in the bottom of an older tank reducing usable capacity, or a failing element heating only part of the water. Both are diagnosable in one visit.
Is it worth repairing a 12-year-old tank?
Rarely for a big repair. Get both prices and compare the repair against a replacement you will need anyway within a year or two.
