Our Case studies

This installation showcases how an air source heat pump system can be successfully integrated into a property with limited ground-level space. Featuring a roof-mounted Grant Aerona³ 10kW heat pump and loft-installed cylinder, the design was tailored to maximise efficiency while overcoming installation constraints.

Situated in Herne Hill, this project involved the installation of a Grant Aerona³ 9kW R290 air source heat pump as part of a wider home renovation. The system was designed around a 48°C flow temperature and paired with a 210L slimline hot water cylinder located within the kitchen. Careful planning was required to accommodate the heat pump's rear patio location, ensure compliance with noise regulations, and optimise performance across the property's three-storey heating system.

This project showcases the integration of a Grant Aerona³ 13kW air source heat pump into a comprehensive home renovation. Featuring a mixed emitter system of underfloor heating and radiators, a dedicated plant room, and a 300L hot water cylinder, the design was carefully engineered to maximise comfort, efficiency and renewable energy performance.

We designed and installed an air source heat pump system for a Bromley property as part of a wider renovation, delivering efficient performance to meet the home’s heating demand. Due to space constraints, a purpose-built external plant room was constructed to house the hot water cylinder, requiring careful system design and pipework integration. Upgrades to existing radiators and precise installation improved overall efficiency throughout the property.

A bespoke air source heat pump system was delivered for a contemporary new-build, designed to operate at low flow temperatures alongside full underfloor heating for optimal efficiency. The installation required tailored solutions, including a custom support frame for the external unit due to unsuitable wall construction. The result is a highly efficient, well-integrated heating system that complements the property’s design and long-term performance needs.

This project involved installing a cascade system of two air source heat pumps in a Southwark property as part of a major renovation and extension. The design addressed increased heating demand and complex pipework over three floors. Despite installation challenges, the system was completed on time using a low loss header to ensure efficient performance. The finished system provides reliable and energy-efficient heating throughout the property.

This project involved the installation of an air source heat pump in a Southwark property, designed for high efficiency and performance. Adjustments were made during the works to accommodate client requirements, while maintaining programme and quality.

A new air source heat pump system was installed in a home in Crawley as part of a renovation. The system was designed to work efficiently in a low heat loss property and delivers strong performance with low energy use. The finished system provides reliable, energy-efficient heating for the home.

To ensure flexibility for the upcoming works, we intentionally left additional length on both the hot and cold-water pipework. This allowed the pipes to be safely repositioned and extended without the need for intrusive alterations once the wall removal and extension were completed.

We designed a tailored heating system using the Grant Aerona3 10kW air source heat pump to replace the existing setup in a retrofit semi-detached house. The system efficiently delivers both hot water and underfloor heating at the required flow temperatures, ensuring comfort throughout the property.
