Merricks North is inland farming and vineyard country between Balnarring and the Tuerong side, made up of large rural holdings with houses set well back from quiet roads. Services are self-provided. Mornington Hot Water is a free referral service. We connect you with licensed hot water plumbers who cover Merricks North. We are not a plumbing business ourselves, and the referral costs you nothing.
Off the gas main, on a big block
Without mains gas, households here run bottled LPG, electric storage or a heat pump. The running cost gap between LPG and a heat pump is wide enough that a replacement is the right moment to price both rather than default to what is already there.
Space and distance are the two rural constants. There is unlimited room for an outdoor unit with good airflow, and a long way between the road and the house, which affects carry time and sometimes travel allowance. Mentioning the distance up front keeps the quote honest.
Tank water is the third factor. Pump pressure and flow rate matter for continuous flow units, and a plumber will check the supply suits the system before recommending 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 sometimes possible for common sizes, and an early request helps given the travel.
Frequently asked questions
Does a long driveway add to the cost?
It can add carry time and travel. It is worth mentioning when you request a quote so the number is accurate.
What is the cheapest system to run out here?
Usually a heat pump, particularly against bottled LPG. Solar works well on an unshaded north-facing roof.
Do I get a compliance certificate?
For plumbing work valued over $750 in Victoria, yes. Keep it with the property records.
