A CO₂ heat pump hot water system is an energy-efficient system that utilizes carbon dioxide (CO₂) as a natural refrigerant to heat water. It operates by extracting ambient heat from the surrounding air, even in low temperatures, and transferring it to the water through a refrigeration cycle. This process involves the CO₂ refrigerant absorbing heat, being compressed to increase its temperature, and then releasing the heat to warm the water before the cycle repeats. Unlike traditional gas or electric water heaters, this allows CO₂ heat pumps such as the Q-ton to achieve a Coefficient of Performance (COP) of 4.3 meaning they generate 4.3 times more heat energy than the electricity they consume. This results in significant energy savings and a reduced carbon footprint.

CO₂ heat pump hot water systems like the Q-ton deliver a powerful combination of efficiency, sustainability, and reliability — making them a smarter choice for commercial applications than traditional gas or electric water heaters.

• Superior Energy Efficiency
  Q-ton uses advanced heat pump technology to extract heat from the air, consuming drastically less energy than conventional electric water heaters. This high efficiency helps reduce electricity demand and improves building performance.
• Lower Carbon Emissions
  By using CO₂ as a natural refrigerant, Q-ton emits up to 74% fewer greenhouse gas emissions than electric systems and 76% less than gas boilers. This makes it ideal for businesses aiming to meet net-zero and NABERS targets.
• High-Temperature Hot Water
  Q-ton can produce hot water up to 90°C, making it suitable for both sanitary use and space heating in sectors like healthcare, food production, and accommodation.
• Reliable in All Climates
  With proven performance in ambient temperatures as low as -25°C, Q-ton provides dependable hot water year-round, even in cold or remote environments.
• Minimal Maintenance
  Backed by over 140 years of Japanese engineering, Q-ton is built with durable components and reliable technology, helping reduce servicing requirements over its long lifespan.
• Smart Controls
  Q-ton can integrate with building management systems (BMS), enabling advanced monitoring for facility management.
• Flexible System Design
  Its modular design allows Q-ton to be scaled up or retrofitted into existing systems, delivering between 3,000 and 100,000 litres of hot water per day, depending on site requirements.
• Legionella Protection
  Q-ton features an legionella protection cycle that superheats the water, making it an excellent choice for aged care and healthcare facilities where hygiene and safety are critical.

The Q-ton CO₂ heat pump is considered better than traditional electric or gas water heaters because it delivers superior environmental performance and long-term cost savings. It produces up to 76% fewer CO₂ emissions than gas boilers and 74% fewer emissions than electric immersion heaters, helping businesses significantly reduce their carbon footprint and meet sustainability targets such as net-zero and improved NABERS ratings.

In addition to its environmental benefits, Q-ton offers outstanding energy efficiency. By using ambient air to generate hot water, it consumes drastically less energy than both traditional systems of electric heaters and gas boilers, resulting in lower operating costs and a faster return on investment. With proven performance in real-world applications, Q-ton is a future-ready solution for commercial hot water needs.

CO₂ heat pump hot water systems are ideal for industries that require a reliable, energy-efficient, and sustainable hot water supply. Some of the key sectors that benefit from this technology include:

• Hospitality & Accommodation – Hotels, resorts, and serviced apartments need large volumes of hot water for guest rooms, kitchens, and laundry facilities.
• Healthcare & Aged Care – Hospitals and aged care facilities require consistent and hygienic hot water for patient care, cleaning, and sterilization.
• Fitness & Recreation – Gyms, swimming pools, and sports centers benefit from high-temperature water for showers, spas, and pool heating.
• Food & Beverage Processing – Breweries, dairies, and food production facilities rely on large-scale hot water for processing, cleaning, and sanitation.
• Manufacturing & Industrial – Factories, textile plants, and pharmaceutical industries require reliable and efficient hot water for production processes.
• Education & Public Facilities – Schools, universities, and government buildings can benefit from CO₂ heat pumps to meet high daily hot water demands while reducing energy costs.
