Why Swap a Cylinder for a Heat Pump?
A heat pump works like a fridge run backwards. It pulls heat out of the surrounding air and moves it into the water, rather than generating heat from scratch.
What that buys you:
- Running costs well below an electric storage cylinder, because the unit moves heat instead of paying to make it
- Stored hot water for the morning and evening peaks, delivered to the taps the same way
- Nothing to burn, so no flue to vent and no gas pipe to lay
Not sure the old cylinder is finished? Whether to fix it or swap it is weighed up on the hot water page, alongside every other system type.
Is Your Place Right for a Heat Pump?
Three things decide it:
- A spot outside for the unit, on a plinth or a wall bracket
- A power circuit the unit can draw from, since a heat pump runs on a steady electrical load
- A household that draws on stored hot water through the day
Where gas already runs to the house, continuous-flow gas is the other option, and the gas fitting page covers that side.
How We Handle the Changeover
The swap follows a set sequence:
- 01
The power and water to the old cylinder are isolated and the tank drained.
- 02
A plinth goes down on firm, level ground beside the old tank position.
- 03
The heat pump unit is set and connected to its storage, with the pipe work made good.
- 04
The system is filled, run and temperature-checked at the taps.
- 05
The old cylinder leaves the property for disposal.
How Is the Changeover Priced?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
What goes into the figure:
- Capacity: a larger storage tank for a bigger family or a second bathroom
- Where the old tank sits and how much pipe work the run to the new unit takes
- Whether the cylinder position can be reused, or a plinth and a new pipe run go in
- Disposal of the old tank, plus any valve upgrades the new unit requires

What Customers Say
One from the solar and heat pump side of the work:
[The plumber] & his young helper were courteous, well mannered & competent when replacing the solar hot water station pump at my property
When We're Not the Right Call
Where the house has no suitable power supply at the unit's spot, a sparkie runs that first and we book the install for after. Rooftop solar panels that make electricity are outside our trade too. If the old tank has burst and flooded the laundry tonight, start with the emergency plumber page and plan the heat pump once the water is off.
Heat Pump Questions, Answered
Why is a heat pump a good fit for homes in Rathmines?
At the last census 92.6 per cent of homes here were separate houses, so a yard or side path is there for the outdoor unit. Frost is close to unknown on this shore, and heat pump units run at their best through exactly that kind of winter. Those two facts make the swap an easy fit for the suburb.
Does the salt air near the lake shorten a heat pump's life?
It can, on the foreshore side. Brackish air finds casings and fittings years sooner than an inland street would see them. The answer is a unit with a corrosion-resistant finish and a spot with clear airflow around it.
Can an older cottage in Rathmines switch to a heat pump?
Yes. The postwar weatherboard and fibro cottages carry the same pipe work as any other house, and the changeover is a matter of siting the unit and connecting it to storage. Before booking, confirm there is a power supply where the unit will stand.
What happens to my old cylinder when the unit goes in?
It gets isolated, drained and disconnected, then carted off site for disposal. Nothing is left for you to arrange. The new system is plumbed in where the old one stood, and the taps are checked before we pack up.
