Capel Sound runs along the bay between Rosebud and Tootgarook on flat, low-lying ground, with modest beach stock from the mid twentieth century steadily being renovated and rebuilt. It mixes permanent residents with holiday owners. Mornington Hot Water is a free referral service. We connect you with licensed hot water plumbers who cover Capel Sound. We are not a plumbing business ourselves, and the referral costs you nothing.
Old tanks and tight budgets
Electric storage is the dominant system here, a lot of it on controlled-load tariffs and a lot of it older than people think. Because the housing is modest, replacement decisions tend to be price driven, and a like-for-like electric swap is often the practical answer. That is a reasonable choice, but it is worth asking for a heat pump price alongside it, because incentives narrow the gap and the running cost difference is real for a full-time household.
Easy access is a genuine local advantage. Flat ground, off-street parking and units in accessible positions keep labour time down, which is why swaps here usually sit at the lower end of a quoted range.
The holiday share brings the familiar idle-tank problem. A system that sits full and unused corrodes with nothing drawing on it and fails at the start of a stay.
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 full breakdown.
Same-day replacement is often possible for common tank sizes when you get in touch in the morning.
Frequently asked questions
Is the cheapest option always electric storage?
Upfront, usually. Over the life of the system a heat pump often costs less overall, which is why getting both numbers is worth the five minutes.
What is a controlled-load tariff?
An off-peak electricity rate that heats the tank overnight at a lower price. It needs a tank big enough to hold a full day of hot water, usually 250L or 315L for a family.
Will my old tank last another year?
If it is over ten years old and already faulty, probably not. The compliance plate gives you the age, and a plumber will give you both the repair and the replacement price.
