____ 01 / HEAT + THERMAL
Heat for the way your site works.
Three applications, each with different temperatures, demand patterns and operating constraints.
THE APPROACH
Start with the heat your site actually needs.
Domestic hot water, space conditioning and process heat call for different designs. We assess demand, temperatures, existing plant and continuity requirements before specifying a heat pump and thermal store.
WHAT WE DO
01
Domestic hot water
Central hot water for amenities, accommodation and facilities, with storage and hygiene needs built into the design.
02
Space heating + cooling
Hydronic heating and cooling planned around comfort, seasonal loads and the existing building systems.
03
Process heat
Hot water and industrial thermal duties sized around production temperatures, timing and reliability.
SYSTEM THINKING
Thermal storage bridges supply and demand.
Heat production / Storage / Peak demand / Backup operation

HEAT PUMP PROJECT EXAMPLE
South-east Melbourne supermarket
330kW
HAIR-TO-WATER HEAT PUMP
HEAT PUMPS + THERMAL STORAGE
Store heat.
Store cold.
Use it when it matters.
Thermal storage makes an engineered heat pump system more flexible around site demand.
THERMAL STORAGE OPTIONS
Match the medium to the temperature and duty.
01
Water storage
A practical baseline for hot‑water and low‑temperature heating duty. Size around usable temperature difference, not just tank volume.
02
Ice storage
On the cold side, an ice tank stores cooling through the water‑to‑ice phase change. Charge and discharge must suit the plant and cooling profile.
03
Phase change material
We commonly use phase change technology where a tighter operating temperature band calls for more useful storage in a compact footprint.
THE STORAGE DENSITY ADVANTAGE
Up to ~4× useful storage density
compared with water in selected temperature bands.
This is an application‑specific material or system comparison, not a guaranteed fourfold reduction in tank size. We select the phase change temperature and verify the usable capacity, fill fraction, heat‑exchanger design, charge and discharge rates, and operating window for each site.
A good storage design also considers plant staging, controls, resilience and service access.
LET'S TALK ABOUT YOUR SITE
Start with the operating problem.
HEAT PUMP APPLICATIONS
Three distinct heat loads.
Each application gets its own route from load assessment to system design.
01 DHW
02 SPACE CONDITIONING
03 PROCESS HEAT
01 / APPLICATION
Domestic hot water
A central hot-water system for facilities where daily demand, hygiene and continuity matter.
Daily draw profile and delivery temperature
Storage volume and peak recovery
Existing gas or electric backup interface
SITE FIT
Aged care, hotels, apartments, amenities and food facilities.
System choice follows the demand profile.
02 / APPLICATION
Space heating + cooling
Heating and cooling designed around the building fabric, hydronic network and occupancy.
Seasonal heating and cooling loads
Distribution temperatures and existing plant
Controls, zoning and operational schedules
SITE FIT
Large buildings, commercial spaces and multi‑site facilities.
Consider both sides of the annual load.
03/ APPLICATION
Process heat
Industrial heat supply integrated with production, recovery opportunities and continuity needs.
Temperature and flow at each process
Shift pattern, peaks and thermal buffering
Waste heat, controls and changeover strategy
SITE FIT
Food, manufacturing and other process‑driven facilities.
Engineer around the working process.

____ 01B / HEAT SOURCE STRATEGY
Choose the source.
Design the lift.
Air, water and recoverable waste heat each change the technical and commercial case.
SOURCE OPTIONS / CONCEPTUAL
AMBIENT AIR
Variable source
WATER LOOP
Available flow
WASTE HEAT
Recovered energy
HEAT PUMP
Useful heat to site
01 HEAT + THERMAL
02 SOLAR + BATTERY
03 OPTIMISATION
04 OPERATIONS + MAINTENANCE
THE APPROACH
Efficiency follows the temperature lift.
Air‑to‑water and water‑to‑water describe how heat is collected and delivered. Waste heat is a source opportunity that can feed a water‑to‑water system. The available source temperature, flow and operating hours determine the achievable performance.
WHAT WE DO
01
Air-to-water
Takes heat from ambient air to produce hot water. Straightforward to site, with performance varying by weather and water temperature.
02
Water-to-water
Takes heat from a suitable water or glycol loop. Source temperature and flow can be steadier when a reliable loop exists.
03
Waste heat recovery
Uses rejected heat from cooling or processes. A warmer usable source can reduce the lift and improve COP, subject to site conditions.
SYSTEM THINKING
A smaller lift can mean a better COP
Source temperature / Required outlet temperature / Flow / Hours of availability
HOW A PROJECT MOVES
01
Identify sources
02
Measure temperatures
03
Model seasonal COP
04
Select architecture
LET'S START WITH YOUR SITE
Share any cooling, refrigeration or process heat rejection data alongside the target hot water temperature.
HEAT SOURCE OPTIONS
Source selection matters.
The available source and required output temperature shape the operating result.
01 AIR-TO-WATER
02 WATER-TO-WATER
03 WASTE HEAT
01 / SOURCE
Air‑to‑water
Outdoor air provides heat to a water circuit. Siting is often simpler, while source conditions vary.
Seasonal ambient conditions and defrost
Required water supply temperature
Space, noise and electrical capacity
DESIGN QUESTION
What is the seasonal performance at the actual water temperature?
Assess the full operating year.
02 / SOURCE
Water‑to‑water
A water or glycol circuit provides heat to the heat pump where a suitable loop is available.
Source temperature and flow stability
Heat exchanger and water quality
Simultaneous heating and cooling potential
DESIGN QUESTION
Is there a dependable source flow when the heat is needed?
Availability matters as much as temperature.
01 / SOURCE STRATEGY
Waste heat recovery
Capture usable rejected heat and upgrade it to the temperature required by the site.
Refrigeration or cooling rejection profile
Process exhaust, return water or effluent
Source‑to‑sink temperature lift and hours
DESIGN QUESTION
Can a warmer source reduce lift and improve the project COP?
Often paired with water‑to‑water plant.
