Tyabb is a Western Port township known for its airfield and antiques, with a compact centre, larger blocks around it and farmland beyond. The housing mixes older township homes, newer infill and semi-rural properties. Mornington Hot Water is a free referral service. We connect you with licensed hot water plumbers who cover Tyabb. We are not a plumbing business ourselves, and the referral costs you nothing.
Township gas, rural bottles
Mains gas reaches parts of the township but not every address on the larger blocks beyond it, and that single fact shapes most replacement decisions here. Properties on mains gas usually replace like for like with gas storage or continuous flow. Properties on bottled LPG face a higher running cost per litre of hot water, which makes a heat pump worth quoting before another gas unit goes in.
Space is the other local advantage. Larger blocks have the room, airflow and distance from neighbours that heat pumps want, so the usual objections about noise and position rarely apply.
Older township homes are the third group, mostly running electric storage on controlled-load tariffs and approaching the age where a replacement is a question of when rather than if.
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
I run on LPG. Is a heat pump cheaper?
Usually, on running cost, once bottle prices are counted. Get both quoted with incentives applied and compare the net installed price against the yearly running cost.
Does a long driveway affect the job?
It adds carry distance and sometimes travel time. Mention it when you ask for a quote.
Can I keep my gas cooktop and switch hot water to a heat pump?
Yes. The two are independent, and plenty of households do exactly that.
