Domestic Hot Water Heat Pumps
Clade domestic hot water heat pumps are engineered to deliver high-efficiency, low-carbon hot water for commercial applications. By capturing ambient heat and upgrading it through a refrigerant cycle, these systems generate hot water with significantly lower operational emissions than conventional boilers, suitable for facilities with high or continuous hot water demand.
All Clade heat pumps can be used to generate domestic hot water (DHW), CO2 has different applications to r290 what’s best will depend on the exact application. Our expert engineering team have designed and implemented numerous strategies for DHW in a variety of situations, for example it is really important to consider secondary circulation and its heat loss because this can result in a very small TD which affects the heat pump operation.

What is a Domestic Hot Water Heat Pump?
A domestic hot water heat pump uses renewable thermal energy from air, ground or water sources to heat potable water via a refrigeration cycle. Instead of burning fuel, it transfers heat from the surrounding environment into a hot water store, delivering efficiencies that often exceed 300% (i.e. 3× the energy input). Clade’s hot water heat pumps are designed for commercial installations where large volumes of hot water are required, and can be configured to operate independently or as part of a wider energy centre alongside space-heating plant and thermal stores. Natural refrigerants are specified where practical to minimise global warming potential.
Benefits of Domestic Hot Water Heat Pumps
Domestic hot water heat pumps provide an efficient, low-carbon solution for meeting commercial hot water demand. By combining reliable performance with future-ready technology, they support cost control, sustainability targets, and long-term compliance across diverse operational settings.
- Lower operating costs: High energy efficiency allows significantly more heat to be generated per unit of electricity, reducing long-term running costs compared with conventional electric or gas water heaters.
- Reduced carbon output: Delivers materially lower operational emissions than traditional hot water systems, supporting decarbonisation strategies and helping organisations cut their overall environmental footprint.
- Stronger ESG performance: Enhances sustainability credentials for ESG reporting, planning requirements, and corporate responsibility commitments, particularly in developments with defined carbon reduction targets.
- Reliable hot water: Designed for continuous, dependable operation to meet consistent or high-volume hot water demand without compromising performance or availability.
- System design flexibility: SAdaptable configurations allow integration across a wide range of commercial environments, from offices and healthcare facilities to industrial and mixed-use developments.
- Future-ready compliance: Uses low-GWP, future-proof refrigerants to reduce regulatory risk and ensure long-term alignment with evolving environmental standards.
How Do Hot Water Heat Pumps Work?
The system extracts low-grade heat from air, ground or water and transfers it to a refrigerant circuit. The refrigerant is compressed, raising its temperature, before transferring that heat into water via a heat exchanger. The result is high-temperature, potable hot water with reduced energy consumption and lower carbon emissions compared to traditional heating.
What Applications Are Hot Water Heat Pumps Suited To?
Clade hot water heat pumps are ideal for environments with high or continuous demand for heated water. Typical applications include:
- Leisure and sports centres with showers and poolside facilities
- Hospitals and healthcare buildings requiring hygiene-critical hot water
- Hotels, student accommodation and multi-unit residential schemes
- Commercial buildings like offices, warehouses, factories, etc.
- Educational campuses with shared services
- Industrial processes needing consistent hot water supply
Each installation can be configured with thermal storage, controls and plant integration to match operational profiles and maximise efficiency.

FAQs About Hot Water Heat Pumps
Clade hot water heat pumps are engineered to provide hot water up to temperatures suitable for commercial potable requirements, often above 60-70 °C. Performance varies with source conditions.
Yes, in many commercial settings heat pumps can replace or supplement existing hot water boilers, delivering lower emissions and operational cost savings. Clade engineers will assess the existing plant room to determine suitability.
While capital costs vary by project size and integration complexity, hot water heat pumps typically deliver long-term savings through significantly lower energy consumption and reduced carbon taxes/charges.
Backup systems are sometimes used in peak demand scenarios. Clade’s design process evaluates load profiles to determine whether a hybrid setup is beneficial.
