Heat pump hot water system installed against the exterior wall of a home
Hot water

Hot water
that sips
daylight.

Hot water is usually the second biggest energy load in a Melbourne home. A heat pump moves warmth from the air into the tank using about a quarter of the power — and we time it to run on your solar surplus.

The problem

The tank in your side passage quietly spends more than almost anything else you own.

An old electric or gas storage unit reheats around the clock, mostly at the exact hours energy costs the most. It's a standing charge disguised as an appliance.

A heat pump uses a quarter of the input and can be scheduled to heat in the middle of the day — when your roof is producing more than the house can use.

Running cost

The cheapest hot
shower in Melbourne.

Indexed annual hot water cost, with an old electric storage tank set at 100. Timing the cycle to daylight is what takes it to single digits.

Why heat pump

Same shower.
A quarter of the input.

COP up to 5.0

Five units of heat delivered for one unit of electricity in mild conditions — physics doing the work.

Solar-timed heating

The cycle runs at midday so the tank charges on surplus, not peak-rate grid power.

Gas-free household

Replacing the last gas appliance lets you abolish the meter and its daily charge.

Sized to real demand

Sized on peak morning draw, so nobody gets the cold end of a school-morning shower.

Quiet placement

37–48dB units on anti-vibration mounts, away from bedroom windows.

Rebates handled

Gone by lunchtime, new one running by three, and the gas meter was abolished a fortnight later. Bills dropped immediately.

Questions

Heat pumps,
answered.

It runs a refrigeration cycle in reverse, pulling warmth out of the surrounding air and moving it into the tank. Because it moves heat rather than creating it, it uses roughly a quarter of the electricity of a conventional electric element.

One system

Every part talks
to the others.

Solar, storage, charging, comfort and hot water are designed together — not bolted on one at a time.
