Industrial and manufacturing processes often use heat for a multitude of different purposes from cooking to curing paint. After the process the heat is degraded to a lower temperature which is of no use and generally expelled to the environment in the form of warm air or water.

Industrial heat pumps are used to capture this low grade heat and transform it back to a that can be used in the process or for other purposes such as heating offices. Reclaiming this waste energy has a direct benefit in terms of utility cost reduction and a measurable carbon saving.

Clade’s natural refrigerant heat pumps are ideal for industrial heat reclaim as they operate at higher temperatures, delivering useful heat with a high COP or efficiency. Our expert design team have years of industrial experience in order to assess, design and implement a reclaim system.

Clade designs, delivers, instals and maintains industrial heat pumps for all kinds of industrial use. With over 30 years of total experience and a proven track record of excellence, we’re proud leaders in energy transformation, sustainable energy and innovation. Our industrial heat pumps are expertly designed and produced as a result of many years of experience developing efficient and environmentally-friendly solutions for our clients across a vast range of industries.


The Oak is our mid-scale CO2 heat pump design. It is suitable for continuous operation and at higher heating capacities for large buildings or processes for example; swimming pools, food production, district heating and factories.


The Beech is our largest CO2 heat pump, bespoke designed and manufactured for each project. Up to 1.4MW in a single unit and encompassing ground, air, water source as well as heat reclaim. Installed as separate evaporators and compressor stations with either glycol or refrigerant connections.


The Aspen is our hydrocarbon CO2 heat pump for smaller applications up to 200KW. Aspen is a more affordable low carbon solution for lower flow temperature but still delivering superb low-carbon heat service and a low GWP refrigerant.

To give our heat pumps customers complete peace of mind. Following installation, commissioning and a 6 month run-in period the actual performance will be assessed against predicted performance. If the heat pump does not meet the guaranteed performance we will refund the cost of the heat pump and remove it from site.

Clade Engineering offers air, ground, and water source commercial heat pumps and refrigeration that use eco-friendly CO2 coolant and can operate either singly or as part of a multi-unit system.

International Heat Pump Suppliers

Clade Engineer Systems design, supply, install and maintain commercial heat pumps across Europe and in Australia. All our heat pumps are made in the UK and shipped from our Technology Centre in Leeds.

Traditional heat recovery systems work by drawing on valuable warm air or water in a property and making it work instead of letting it go to waste.

The heat recovery process works by continuously converting heat waste and converting it into hot water. Essentially, this is a process of recycling warm air and putting it to good use. Without heat recovery systems, this wasted air would continue to circulate, becoming stale. It’s then replaced by colder air which is then warmed up by the ventilation system. And the already stale air, rather than being recycled, is expelled into the atmosphere and wasted.

A traditional heat recovery system can work through a ventilation system which is placed at the top of a building. They work to draw heat from outgoing air and pass it into the air that’s coming in. These heat recovery systems don’t negate the need for a boiler or other technology to heat a property or building but they do compliment and help them work more efficiently by recycling the warm air. This means you get the most out of it. They can help save on energy bills, reduce carbon emissions and keep a property warmer in the winter months.

About CO2 Heat Pumps


Heat pumps are the latest and greatest in clean renewable heat. Heat pumps, unlike traditional heat recovery systems, are more efficient, and cost-effective and do a better job at reducing carbon emissions in the long run. There are also several different types of heat pumps which draw energy and convert it into heat. They can extract ambient temperatures from the ground, water or air, warm it and bring it into your property or building for natural heating.

Heat pumps use less electricity to run than traditional heat recovery systems. And an added benefit to heat pumps as compared to traditional heat recovery systems is that the cycle can be reversed so that they work as cooling air conditioners. They’re energy-efficient, meaning lower running costs. They require less maintenance, they’re safer and are very effective at reducing carbon emissions. Water source heat pump systems, for example, can reach high efficiencies of up to 600%.

Businesses and individuals who need to reduce their carbon footprint will do well with heat pumps. And in the UK, the government is incentivising the use of heat pumps for efficient and environmentally-friendly energy to help the country hit net zero by 2050 by offering part payment for installing them to businesses, landlords and individuals.


Clade is the UKs leading manufacturer of natural refrigerant heat pumps. With significant R&D, field trials and a proven deployed portfolio of over 500 natural refrigerant appliances there are no other UK manufacturers that come close to our expertise and experience.

Operating on a national basis from our green manufacturing Technology Centre in Leeds and our Head Office in Bristol, which has achieved CEEQUAL status and the internationally recognised BREEAM Excellent standard, we design, manufacture, supply and maintain heat pumps and refrigeration around the world.

Clade Engineering is able to provide heat pumps as either air, ground, or water source. The most suitable type of heat pump depends on several factors related to your property. Generally, air source heat pumps are the most popular because they have the fewest requirements to install. Any type of heat pump can provide hot water and heating to your building.

Heat pumps using CO2 refrigerant as the heat source are friendly to the environment because the CO2 they use stays contained within the appliance and does not get released into the atmosphere. Furthermore, the CO2 we use in our heat pumps has the lowest global warming potential (GWP) of 1 compared to 1000’s for other refrigerants which will all significantly reduce the carbon footprint of your building.

Clade are the industry leaders in heat pump technology. As the heat in buildings challenge became clearer, Clade began the R&D for a new range of heat pumps which would provide a solution for a growing market. The first heat pump was installed in a Co-Op store and achieved a staggering SCOP of 3.7. We have over 36 years of experience and all of our systems are designed and manufactured in the UK.

Our heat pumps meet environmental standards by using a natural refrigerant like CO2. It has a Global Warming Potential (GWP) of 1, which reduces both cost and emissions.

Clade offers a full start to finish heat pumps solution. Our team of engineers design your system, manufacture and supply your heat pumps from our product range, our installation team ensures your heat pump is fully functional and our after sales support team provides ongoing maintenance. You can pick and choose as many or as few of our services to suit your requirements.

We ensure that your heat pump system continues to function. Our heat pumps can generate heat from 50kW to multi mega-watt, with a maximum water temperature of over 80 degrees Celsius and a minimum external air temperature of -20 degrees Celsius. Each of our heat pumps also comes with total cooling recovery to ensure a high quality of continued functionality.
