Q-ton

The Q-ton CO₂ heat pump offers clear advantages over traditional electric and gas boilers, particularly in emissions, energy use, and year-round performance.

Unlike gas boilers, Q-ton produces zero on-site emissions and delivers up to 76% fewer CO₂ emissions, helping organisations meet net-zero targets and reduce their environmental footprint. Compared to electric immersion heaters, it cuts emissions by up to 74%, making it a more sustainable option across the board.

Q-ton also uses significantly less energy than electric or gas systems by extracting heat from the air, rather than generating it directly through combustion or resistance. This leads to drastically lower running costs over time.

Where traditional systems often struggle in cooler conditions, Q-ton is designed for superior low-temperature performance — reliably delivering up to 90°C hot water even when ambient temperatures drop to -25°C. This makes it ideal for colder climates and applications requiring consistent, high-temperature output.

In short, Q-ton offers a more efficient, lower-emission, and climate-resilient alternative to both gas and electric water heaters — making it a smarter choice for commercial hot water systems.

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.

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.
