Red Hill is the heart of the Peninsula hinterland: vineyards, orchards, the market, and rural homes under heavy tree cover on rolling ridge country. Most properties here supply their own water and are not connected to a gas main. Mornington Hot Water is a free referral service. We connect you with licensed hot water plumbers who cover Red Hill. We are not a plumbing business ourselves, and the referral costs you nothing.
LPG, tank water and tree cover
Three local conditions shape every hot water decision here. The first is energy supply. Without mains gas, households run bottled LPG, electric storage or heat pumps, and LPG running costs make the heat pump comparison worth doing properly rather than defaulting to another bottle-fed unit.
The second is water. Properties on rainwater tanks need the system matched to their pump and pressure, particularly continuous flow units that need a minimum flow rate to fire reliably.
The third is canopy. Red Hill is densely treed, which is poor news for solar hot water on many blocks. Collectors need an unshaded north-facing roof, and a shading assessment before quoting is not optional. Where the roof does suit, running costs are excellent, and where it does not, a heat pump is usually the better answer.
Frosty mornings are a fourth consideration. The hinterland gets colder than the coast, and while modern heat pumps are built for it, siting and frost protection are worth asking about.
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
My continuous flow unit will not fire on tank water. Why?
It may not be getting the minimum flow it needs. Pump pressure and flow rate matter, and a plumber can check whether the unit or the supply is the limiting factor.
Is solar worth it under heavy tree cover?
Usually not without an unshaded north-facing roof section. Have it assessed honestly before spending, and compare a heat pump.
How much does LPG hot water cost to run?
More per litre of hot water than mains gas, enough that hot water is often the largest LPG cost in a hinterland house. That is the number to compare a heat pump against.
