Quantum Energy Heat Pump Hot Water Systems
Quantum Energy specialises in heat pump hot water, with residential
systems from compact 150L units through to large 340L family systems and
higher-output Titan heat pumps for commercial or very high-demand
applications. JR Gas & Water supplies and installs Quantum heat pumps
across Brisbane, the Gold Coast and eligible South East Queensland
service areas.
Quantum has a long history in Australian heat pump water heating, with
technology development dating back to research undertaken in the
mid-1970s. The current domestic range uses R290 refrigerant and combines
the storage cylinder and refrigeration system into an integrated
all-in-one design.
The main residential choice is therefore capacity: 150L, 200L, 270L or
340L. Quantum's Titan range sits above the standard domestic systems and
is designed for larger hot water loads where greater heating output,
recovery and commercial scalability are required.

Titan is not simply a more expensive domestic Quantum.
Titan systems use a higher-output platform and are intended for larger hot
water loads. Compare the normal 150L–340L domestic range first for standard
household installations.
Quantum 150L, 200L, 270L & 340L Heat Pumps
Quantum's current domestic range provides four clear storage capacities.
All current domestic models use heat from the surrounding air to heat the
stored water and use R290 refrigerant.
Quantum 150L
Quantum positions the 150L for small homes, granny flats and lower hot
water demand. Manufacturer guidance indicates approximately 1–2 people
and one bathroom, subject to actual usage.
From
Quantum 200L
The 200L provides more stored capacity while retaining a relatively
compact footprint. Quantum positions it around medium-sized household
demand.
From
Quantum 270L
The 270L is the main family-size middle ground. Quantum identifies it
for average-size families, with current manufacturer guidance around
3–5 people and up to two bathrooms depending on demand.
From
Quantum 340L
The 340L provides the greatest stored capacity in the normal domestic
range and is aimed at larger families and homes with heavier peak hot
water demand.
From
Current Quantum R290 Heat Pump Technology
Quantum's current 150L, 200L, 270L and 340L domestic models use R290
refrigerant. These models share a similar basic platform but are scaled
around different household storage requirements.
Current manufacturer specifications list the domestic systems as
single-phase units using a 10A circuit. The 150L and 200L models have a
listed 0.84kW power input and the 270L and 340L likewise use a relatively
low electrical input compared with direct-resistance electric storage.
That can make Quantum particularly relevant where a homeowner wants a heat
pump without the high electrical demand associated with some other forms of
electric hot water.
Current domestic Quantum systems are element-free in normal heat-pump
operation.
Quantum promotes its domestic heat pump technology around extracting heat
from ambient air rather than depending on a conventional electric booster
element for normal water heating.
What Size Quantum Heat Pump Do I Need?
Capacity should be selected from actual household hot water demand rather
than simply buying the largest Quantum available.
JR's sizing method uses approximately 40 litres per person per day for light
usage, 50 litres for average usage and 65 litres for higher usage before
matching the household to an appropriate system size.

Do not size from occupant count alone.
Long showers, baths, multiple bathrooms and several users drawing hot water
close together can push a household toward the next capacity.
Quantum 270L vs 340L
The 270L and 340L are the main Quantum sizes likely to be compared by
family households. Both use the same general R290 heat-pump approach, but
the 340L provides substantially greater stored capacity.
Choose Quantum 270L If…
Household demand is moderate, the home is typically around the
average-family range and there is no need to pay for unnecessary
storage capacity.
From
Choose Quantum 340L If…
The household is larger, hot water use is heavier or there are several
bathrooms and concentrated morning or evening demand periods.

How Efficient Is a Quantum Heat Pump?
Quantum heat pumps use a reverse-refrigeration process to transfer heat from
ambient air into the hot water cylinder. This can provide several units of
heat energy for each unit of electrical energy consumed.
Current manufacturer data lists a COP of approximately 4.30 at 20°C for the
150L and 200L models and approximately 4.53 at 20°C for the 270L and 340L
domestic systems.
Actual household energy use will vary with ambient temperature, hot water
demand, operating schedule, system size and electricity tariff, so test COP
figures should not be interpreted as a fixed annual household saving.
Does a Quantum Heat Pump Work in Cold Weather?
Quantum designs its current domestic heat pumps to operate across a broad
ambient-temperature range. Current manufacturer specifications list
operation down to approximately -10°C on the present domestic models.
South East Queensland conditions are generally far milder than that lower
operating limit, although efficiency and recovery naturally change with
ambient temperature.
Quantum Titan 340L Heat Pump Systems
Quantum Titan sits above the standard residential range. Titan systems use
larger refrigeration components and provide substantially greater hot water
production for commercial, accommodation and other high-demand
applications.
Current Quantum Titan systems can also be manifolded together, allowing
several units to work as a larger system while providing redundancy for
demanding sites.
Quantum Titan Compact 340L
An integrated high-output 340L heat pump designed for commercial or
unusually high hot water demand while keeping the system in one compact
package.
From
Quantum Titan Split 340L
The Titan Split separates the refrigeration module from the storage
tank, providing greater positioning flexibility and allowing the
evaporator to be installed remotely from the cylinder within the
manufacturer's installation limits.
From
Standard house or Titan?
Most normal residential installations should begin by comparing the
standard 150L–340L Quantum domestic range. Titan is designed for much larger
recovery requirements and high hot water loads.
Quantum Heat Pumps with Solar PV
Heat pump hot water can work particularly well with rooftop solar because
the heater can be operated during periods when the property is producing
solar electricity.
Instead of exporting all excess daytime generation, some of that electricity
can be used to heat water and effectively store energy in the tank for use
later in the day.
The actual financial benefit depends on the home's solar production,
electricity tariff, export value and household hot water pattern.
Replacing Electric Hot Water with Quantum
Replacing a conventional electric storage system is one of the main
applications for Quantum heat pumps. The property retains stored hot water
but changes the primary method of heating from direct electrical resistance
to heat-pump technology.
The new Quantum does not necessarily need to match the old cylinder's litre
capacity exactly. Household demand, heat-pump recovery and the available
150L, 200L, 270L and 340L sizes should all be considered.
Installation also needs suitable airflow, drainage, plumbing, electrical
supply and an appropriate base.
Quantum Heat Pump Rebates & STCs
Eligible Quantum heat pump installations may qualify for Small-scale
Technology Certificates where the exact approved product and installation
meet the applicable scheme requirements.
Quantum also promotes eligible rebate pathways across its current domestic
range. The actual incentive should always be confirmed against the exact
model, installation date, location and scheme rules.
Is Quantum a Good Heat Pump Hot Water System?
Quantum is one of the longer-established specialist heat pump brands in
Australia. The company's origins trace back to Australian heat-pump water
heating research in the 1970s, followed by decades of ongoing product
development.
Unlike broad hot water manufacturers that also produce gas and conventional
electric systems, Quantum is heavily focused on heat-pump technology across
domestic and commercial applications.
The current residential range is also straightforward to understand, with
four capacities sharing a similar R290 integrated platform. This makes
sizing and household demand the main buying decision rather than navigating
several completely different technologies.
Quantum Heat Pump Warranty
Current Quantum domestic specifications list a five-year tank warranty and
two-year coverage for electrical and refrigeration components, subject to
the manufacturer's current warranty terms and installation requirements.
The warranty applying to the exact model and installation should always be
checked at the time of purchase because manufacturer warranty terms can
change.
Quantum Heat Pump Installation Brisbane & Gold Coast
JR Gas & Water supplies and installs eligible Quantum heat pump hot water
systems throughout Brisbane, the Gold Coast and eligible South East
Queensland service areas.
Installation needs to consider system size, airflow, condensate drainage,
plumbing, electrical supply, base position and physical clearances around
the unit.
The 340L domestic system is physically much larger and heavier than the
150L and 200L models, while Titan products have additional high-demand
installation requirements. The correct product should therefore be chosen
with the actual site in mind.
