Heat Pump Hot Water Systems in Geelong West

On a cottage built to both boundaries there is no route from the street to the rear yard except through the house. That means the old tank comes out through a hallway, and the new tank and outdoor unit go in the same way, over floor protection, around a corner that was built for a person rather than a 300 litre cylinder. It is doable. It takes longer and it costs more, and both of those belong on the quote before the day rather than as a variation on it.

Where there is a gap but it is under a metre, the question changes from whether we can get past to whether the unit can run there. A heat pump wedged between a paling fence and a weatherboard wall restricts airflow, traps the cold discharge and reflects compressor noise straight into the cottage next door, which on a 9 to 12 metre frontage is very close indeed.

The incumbent here is usually one of two things. In renovated cottages it is a gas instantaneous unit hanging on an external wall, fitted during whichever renovation last touched the bathroom. In unrenovated ones it is an electric storage tank in a lean-to laundry or a side alcove. Both replace fine, but neither position transfers automatically to a heat pump because the new unit is larger and it needs air.

Going from gas instantaneous to a heat pump is also a genuine change in behaviour, not just in fuel. Instantaneous units never run out. A heat pump stores hot water and reheats more slowly, so tank sizing matters in a way it did not before. On a one bathroom cottage that is easy. On a renovated cottage with two bathrooms and a family we size for the busiest morning rather than the average one.

On a 9 to 12 metre frontage with cottages built to the boundary, the neighbouring bedroom window can be three or four metres from where you would like to put a compressor. Heat pump noise is comparable to a split system outdoor unit and only while it is running, but placement is what decides whether anyone notices. Two hard parallel surfaces a metre apart make it worse, not better.

Original timber framing on Victorian cottages is often undersized by modern standards, and light timber construction carries structure-borne noise well. Anti vibration mounts are standard on every install here, and we point the discharge into open space rather than at a fence. The daytime timer window helps twice, because it improves efficiency and it removes any chance of a compressor starting beside a bedroom at five in the morning.

Geelong West sits about a kilometre from Corio Bay, so there is genuine salt exposure, milder than the surf coast but enough to matter for outdoor enclosures, bracket feet and condenser fins. We use a weatherproof isolator and coastal grade fixings as standard, and a fresh water rinse of the coil each spring is worth the five minutes it takes.

On the electrical side, the cottages that have been renovated repeatedly are the interesting ones. Original wiring, an 1980s addition, a 1990s kitchen circuit and a modern rear extension sub-board frequently coexist with varying documentation. Adding a dedicated hot water circuit means working out what is live and what feeds what first, and sometimes the extension sub-board is a better source than the original board at the front of the house.

Supplied and installed, the system is $3,000 to $4,500 before incentives. Solar Homes contributes up to $1,000, or up to $1,400 for a locally made product, under a combined household income cap of $150,000 from 1 July 2026. Victorian Energy Upgrades applies a discount directly to the invoice, no income test, property at least two years old, $200 including GST minimum contribution. Federal STCs are worth roughly $300 to $600. Most households pay a few hundred dollars up to about $1,500.

What moves a Geelong West price is labour, not hardware. An internal removal route, a long pipe and cable run to a rear yard position and a board that needs work can add more than the appliance costs. We are 60km away in Altona and book work here in scheduled blocks, nominating the week rather than the hour, which on a job that needs an access assessment anyway is the sensible way to run it.
