Industrial Heat Pumps

A range of air to water, water to water and reverse cycle heat pumps, operating on Propane R290, R1234ze or R1233zd refrigerants.

Heat Pumps – The Aqua ProHeat Range

Heat pump technology has evolved over recent years, and now provides a highly cost effective, renewable approach to temperature control. By transferring heat from the external air – or recycling it from a waste heat source – rather than generating it, heat pumps offer a host of benefits.  These include minimal operating costs, reduced carbon impact and impressive levels of energy efficiency.

For applications requiring cooling & heating – or just heating – find out how our Aqua ProHeat range could transform your business for the years ahead.

How Do Industrial Heat Pumps Work?

Heat pumps use the thermodynamic cycle to transfer heat from air, or water, which can then be used for heating. Refrigerant circulates within the system and is key to the heat transfer process. Our range includes three types of heat pump.

Air to water – heat from the ambient air is taken and boosted to the required temperature by way of the thermodynamic cycle. These units are suited to commercial or industrial applications that need a direct hot water source, for example public facilities such as schools and hospitals or low-grade heating in industrial processes.

Aqua ProHeat units work with an external air temperature as low as -15°C. They can achieve 70°C hot water using R1234ze or 65°C using R290. Units available later this year will be able to achieve 85°C on R1234ze or 75°C R290.

Water to water – waste heat is recycled and can be used as high-grade hot water, often referred to as heat reclaim. Ideal for industrial processes where waste heat would otherwise be dissipated to the environment. The heat pump recycles the heat as high-grade hot water.

The resulting hot water can then be used elsewhere within the process, or facility. For example, in the food sector, the reclaimed heat can be used at the pasteurisation stage, or for cleaning-in-place-systems (CIP). Alternatively, it could be used for heating a large space, such as an office or warehousing.

Our water to water units can achieve 120°C on HFO refrigerants or 75°C on propane.

Reverse cycle – designed for HVAC applications, these units can provide heat in the Winter and cooling in Summer. Units operate down to -15°C ambient.

Ice Cream Producer Scoops Benefits of Heat Pump Technology

As an artisan producer, with their own dairy herd, sustainability and quality are at the heart of their business. The production process centred around a chiller, a heat exchanger and 200kW gas boiler. This equipment provided all the heating & cooling necessary for their production line.

We were asked to review this process for our client, to determine if any energy efficiencies could be gained and improvements made.

Features & Benefits of our Industrial Heat Pumps

  • Energy efficient design – with scroll, screw, or semi-hermetic compressor technology
  • Air to water units work with external air temperature as low as -15°C
  • Intelligently controlled defrost function – guarantees hot water temperatures for critical processes
  • EC fans – maximises efficiencies
  • Ultra-low GWP refrigerants
  • Eliminates – or dramatically reduces – the need for a boiler and reliance on gas

Sustainability, Efficiency & ROI

Aqua’s commercial heat pump range delivers on all fronts when it comes to reducing energy consumption and maximising efficiencies.

By providing a hot water supply, you negate the need for a boiler. For many customers this eliminates their reliance on gas or oil, reducing their carbon impact. For those using an electric boiler, whilst a heat pump will still use electricity, the amount of kW used is significantly reduced. With water to water units, you are recycling your waste heat at zero cost!

Refrigerants used within our heat pumps have zero Ozone Depletion Potential (ODP) and an ultra-low Global Warming Potential. The GWP of R290 is < 3, R1234ze is < 7 and R1233zd is just 1. 

Return on investment on heat pumps is fast, due to their energy efficient design and low operating costs.

Heat Pump Rental

We also have a range of  heat pumps within our Hire fleet, available to rent on short, medium or longer term agreements.


asked questions

Industrial heat pumps are essential for energy-efficient heating in various industrial applications. The COP (Coefficient of Performance) of a heat pump depends on the temperature of the heat source and the temperature of the hot water required from the heat pump.  The standard COP range is 2.5 to 5. When selecting an industrial heat pump, considering the COP in conjunction with other performance metrics and environmental conditions is crucial for ensuring optimal efficiency and sustainability. Contact Aqua Cooling for a consultation can provide insights into the best heat pump solutions tailored to meet your specific industrial needs while ensuring efficiency and sustainability.

Due to the change in technology, with the right conditions, temperatures as high as 120°C can be achieved. Understanding the specific requirements and operational conditions is crucial when considering a heat pump for applications that demand high temperatures.

Choosing the right heat pump for industrial applications depends on the specific heating needs and operational conditions of the facility. There are 3 main types of heat pump, air to water, water to water and reverse cycle.  Any manufacturing process that requires heating and has a waste heat production from that or other processes can benefit from heat pumps.  Common applications include pasteurisation, pre heating of air for drying products, space heating & HVAC, but the list is endless.

When selecting a heat pump, it’s essential to consider factors such as the type of heat source available, the temperature requirements of the process, the climatic conditions of the installation site, and the overall energy efficiency goals of the facility.
