Student accommodation today is about more than just a place to sleep. It’s about designing resilient, energy-smart environments that support modern living. Brooklyn House in Pretoria’s academic heartland sets that new benchmark.
This newly completed development, home to 297 students, places sustainability at its core. Central to this is a future-forward hot water solution powered by a collaboration between Alliance Direct Heat Pumps and Solar Heat Accumulators, working in perfect synergy.
Appointed by developer Mile Investments, and with wet services design by WFP Consulting Engineers and architecture by Boogertman + Partners, the project required a system that could meet high daily hot water demand while reducing operational costs and environmental impact.
The system installed:
- 4 x 80kW Alliance Direct Heat Pumps
- 2 x 15,000L Solar Heat Accumulator Tanks from Solar Heat Exchangers
With a 320kW total heating capacity, this solution guarantees a consistent 60°C temperature within the accumulator tanks, ensuring hot water is available day or night, rain or shine.
The innovation lies in the combination of technologies. Alliance’s heat pumps extract ambient heat from the environment, drastically reducing energy consumption. Instead of heating water directly, energy is transferred to Solar Heat Accumulator Tanks, which capture and store the heat. This indirect heating method protects the longevity of the heat pumps and maintains energy efficiency over time.
The results? Up to 70% savings in water heating costs, reduced strain on electrical grids, and reliable, efficient service to hundreds of students.
Compact, quiet, and highly efficient even across South Africa’s variable climates, this system is tailored for high-density urban projects with limited plant space without sacrificing reliability or sustainability.
Together, Solar Heat Exchangers and Alliance deliver integrated heating solutions that offer developers, engineers, and contractors a smarter way forward: durable systems, lower operational costs, and long-term sustainability.
Solar Heat Exchangers, Alliance, and the Fourways Group combine smart heat pump innovation with durable accumulator technology, delivering future-proof, energy-saving solutions backed by nationwide support and proven reliability.
