Why swap the tank for a heat pump?
The mechanism is simple. A heat pump collects heat already in the air and pumps it into the tank instead of driving an element. Same showers, same pressure, far less power per litre of hot water than an ageing electric storage tank.
The timing usually decides itself. Across the pre-1940 and interwar cottage stock, original units have been limping along for decades, and when one finally quits the question is what replaces it, not whether. A heat pump is one of the answers, alongside gas, solar and a straight like-for-like swap, and the hot water in Mayfield page lays out the full set of options side by side.
Cottages and infill, both asking for it
Two waves of housing drive this job. The older wave is the cottage grid, where a failed tank is the trigger and the heat pump is the upgrade. The newer wave is infill: area-level figures list 249 dwellings approved here over five years, and heat pumps are a common pick in those builds because the running cost is known from day one.
The suburb has history with the technology too. Area-level figures list 988 heat pump installs around this suburb, so a unit on a wall or beside a side passage is a familiar sight, not an experiment. The weather pulls the same way, with humid summers, winters that stay mild, and a machine happy to work through either.
What a heat pump install involves
The work runs through four steps, cottage or new build:
- 01
Ring or send the form
Call (02) 4063 1093 or use the form to explain the fault. We ask enough to bring the right equipment the first time.
- 02
A fixed price first
A plumber inspects the job and names a fixed figure up front. Nothing gets started until you give the go-ahead.
- 03
The swap itself
We remove the old tank, set the heat pump on its plinth or bracket, then connect and pressure-test the water, valve and tempering pipework.
- 04
Covered for a year
Every job carries our 365-day warranty on all work. If something we did isn't right, ring the same number.
What moves the price of the swap?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
The figure is built from:
- The unit size, since a two-person cottage needs a smaller machine than a full house
- The position, since water pipes running further to a new spot means more pipe and more labour
- The state of the old pipework, because cottage stock can hide corroded fittings that get replaced while the job is open
- Carting off the old tank, already inside the quote
When We're Not the Right Call
A heat pump needs its own power circuit. Switchboard work is for a licensed electrician, so that part gets handed to them rather than quoted by us. You hear it before the van arrives, not after the unit is on the wall.
And if the old tank would survive with a valve or an element, the honest call is repair, because a smaller job is a smaller bill. If the tank has been leaking into the floor for months, water leak detection finds how far the damage travelled.
What Customers Say
[The plumber] & his young helper were courteous, well mannered & competent when replacing the solar hot water station pump at my property
Where does a heat pump hot water unit go on a Mayfield cottage?
Most cottages here sit on tight lots, so the unit usually mounts on an external wall or stands in the side passage near the old tank position. Keeping it close keeps the pipe run short, which also keeps the price down. We confirm the spot with you before anything is ordered.
Do heat pumps cope with humid Hunter summers?
Yes. Humid air still carries plenty of heat for the unit to collect. Average annual frost days sit at 0.2 in area-level figures, so cold mornings seldom slow it down either.
Does the old electric tank get taken away?
It does. The old tank is disconnected, drained and loaded onto the vehicle, and removal is written into the quote rather than added later. If it has been weeping for a while, we point out any water damage around the base before we take it.
Will a heat pump cut the power bill on an old cottage?
A heat pump warms water by pulling warmth out of the air rather than heating with an element, so it uses far less power than an old storage tank. The exact saving depends on the household, and we size the unit to the number of people actually living there.
