Heat Pump Hot Water Systems in Highton

A 1960s Highton brick veneer usually has an original board, often with ceramic fuses, and a 250 to 315 litre electric storage tank on controlled load quietly running an element every night. A 1980s house typically has a serviceable board with no spare ways left. A 2010s house on the north west edge has a modern board with residual current protection and capacity to spare, and the hot water job is a straight addition.

That is not a rule, it is a starting point that gets confirmed on site. What it does mean is that a Highton quote can be scoped sensibly over the phone before the visit, which is not true in Geelong West or the Bellarine holiday suburbs. A heat pump needs its own dedicated circuit and isolator regardless of which of those three houses you own.

The elevation that makes Highton good for solar also makes it windier than the flat suburbs down on the plain. For a heat pump that is not a structural problem the way it is for roof-mounted rail, but it does affect placement. A unit sited on an exposed western corner has cold air driven across the coil all winter, which is not the same as having warm air drawn through it deliberately.

We put the unit on the sheltered side where the block allows, out of the prevailing wind, with the discharge pointed into open space rather than back at a wall. Highton blocks from the 1960s to the 1980s have real side access, so there is usually a choice of position, which is a luxury compared with the inner suburbs. On the newer north west subdivisions where garages run to the boundary the choice narrows.

Homes on the slope often have a long run from the street to the meter position, and that is the single biggest cost variable on any supply upgrade in Highton. For a heat pump alone it usually does not come up, because the load is modest and it goes on a new final subcircuit at the existing board.

Where it does come up is on a house that is electrifying more than one thing at once. A heat pump plus an EV charger plus reverse cycle heating on a 1960s board with original consumer mains is a different conversation to a hot water swap, and it is worth having once rather than three times. We calculate the maximum demand against the real appliance list rather than a rule of thumb.

Highton solar numbers are usually better than the Geelong average, because the elevated position on the Barrabool Hills means very little overshadowing from neighbours and concrete tile or Colorbond hips at 20 to 25 degrees give usable planes. If you already have panels, the heat pump is the best load you can put under them.

Set the heating cycle for the early afternoon and the tank fills on generation that would otherwise export for a few cents, while the compressor runs in the warmest air of the day when it is most efficient. Against a conventional electric storage tank a heat pump uses roughly one third of the electricity for the same hot water. Against gas, the difference is less about a single efficiency number and more about the fact that gas cannot use your solar at all, and that the daily supply charge keeps being paid.

Solar Homes contributes up to $1,000, or up to $1,400 for a locally made product, subject to a combined household income cap of $150,000 from 1 July 2026. Victorian Energy Upgrades applies a discount directly to the invoice with no income test, on a property at least two years old, with a minimum customer contribution of $200 including GST. Federal STCs are worth roughly $300 to $600. Most Highton households end up paying from a few hundred dollars up to about $1,500 against an installed cost of $3,000 to $4,500.

The two year property age test is the one to watch on the newest north west streets, because a house completed last year does not qualify for VEU. Highton is about 65km from our Altona base, so we book work here in scheduled blocks and nominate the week rather than the hour. No same-day attendance and no emergency response, because at that distance we could not deliver either.
