How a Heat Pump Heats Water
A heat pump moves warmth rather than creating it, which is why it uses so much less power than an element on its own. The parts are simple enough to explain in four lines:
- A fan pulls outside air across a refrigerant coil, and the compressor concentrates that warmth into the tank water.
- It works like a fridge turned around, harvesting heat instead of dumping it.
- Because the heat comes free from the air, running costs stay low compared with a standard electric cylinder.
- Tank water is held at 60°C for Legionella control, and a tempering valve caps what reaches the shower at 50°C.

Where a Heat Pump Suits a Home
The technology is brilliant when the house matches it, and a waste of money when it does not. These points decide the fit:
- Households of one or two people see the strongest return, and the census put the average here at 1.9.
- You need an outdoor spot with steady airflow, clear of bedroom windows, because the compressor and fan both make noise.
- Homes wanting off gas, or landlords replacing a dead electric cylinder, get a straightforward path to an efficient system.
How We Fit a Heat Pump
- 1

Site check first
We look at airflow, how far the unit sits from bedroom windows, and how the old tank is fed and isolated.
- 2

Quote in writing
Capacity, siting and any valve or pipe work go into one figure you approve before we start.
- 3

Swap and connect
The old cylinder comes out, the heat pump goes onto its base, and the water and valves are joined and tested.
- 4

Set and run through
We set the thermostat, confirm the tempering valve, and walk you through the controls before we leave.

What Shapes a Heat Pump Quote
Hamilton Hot Water Services prices the whole job, and four things set the figure:
- The tank capacity matched to your household's morning demand.
- Where the unit sits and how easy the access is, including body corporate approvals and lift bookings in the towers.
- Whether the existing power supply can run the new unit unchanged, with any upgrade handled by an electrician.
- The condition of the valves and pipe runs we connect into.
You get a fixed quote for the whole hot water job first, and we only start once you've approved it. Flat-rate pricing means no hidden fees and no extra fee for weekend or after-hours call-outs, and you can fix now, pay later.

Heat Pump Notes for These Streets
Flats set the siting question
Seven homes in ten here were flats or apartments at the last census, so the usual decision is not which brand but where a compressor can legally and quietly go, and that conversation happens with the body corporate before the quote hardens.
The climate does the unit a favour
Frost never settles on these streets, with zero frost days on the census record, so the compressor keeps finding warmth in the air even on a July morning.
Uptake is already visible
Across the postcode, 236 heat pump installs sit on the public record, which tells you plenty of neighbours have already tested the idea in courtyards and side passages.

When a Heat Pump Is Not the Answer
A heat pump needs outdoor air, so a fully enclosed cupboard rules it out, and that makes a heat pump not the right call for the home until a suitable spot opens up. Any new circuit or switchboard work belongs to a licensed electrician rather than to us. For those homes, our hot water replacement page covers the systems that do fit, and a brand-new build is covered on hot water installation.
Frequently Asked Questions
Call (07) 3523 1736Do heat pumps still work through a Hamilton winter?
They do, because winters here are mild and the long-run census record shows zero frost days, so the unit never loses its heat source and keeps making hot water all year.
Can a heat pump go outside a Northshore apartment?
Often yes, where an outdoor corner gets steady airflow and sits clear of bedroom windows, though in the Northshore towers the body corporate has the final say on placement, and we work within it.
Does Energex need to know when a tank becomes a heat pump?
Usually the existing circuit keeps running the new unit without changes, and if a supply upgrade is ever needed, an electrician handles that wiring while we cover the plumbing side only.
How popular are heat pumps around Hamilton?
The postcode record already shows 236 heat pump installs, and with zero frost days plus a warm humid wet season, the technology suits these streets very well indeed.
What size heat pump suits a household here?
Census figures put the average household at 1.9 people, so most units here serve one or two people, and we size the system to your real morning demand rather than guesswork.
