The New Makers
Delft
The Blue WWHR system was implemented to support TheNewMakers' sustainable, timber-based, prefab modular approach and meet strict national energy regulations. Each ComfortCabin bathroom module includes one unit, connected to a shared hot water system serving multiple apartments—maximizing energy recovery and reducing environmental impact. Selected for its unique suitability in stacked construction and fast, easy construction, the system solves the challenge of integrating efficient heat recovery in modular buildings. Hamwells provided proactive consultancy and technical support throughout design and execution, ensuring seamless integration into prefab wooden modules. Its low-maintenance and high-efficiency performance make it a future-proof solution for sustainable urban living.
The Blue system achieves ~80 MWh and 27 tons CO₂ annual savings across 102 dwellings. It eliminates the need for a larger DHW system, reducing spatial and capital requirements. Over 90% of system cost is recovered through infrastructure and installation efficiencies. Tenants realize up to €250/year in energy savings. With a 15–25 year service life, it ensures strong ROI, sustainability impact, and occupant value. Prefabrication by TheNewMakers enables rapid, low-complexity deployment.
The Blue shower systems use the heat of the shower wastewater to preheat the cold water supply. By doing this, the demand for hot water drops significantly, which means a lower energy consumption. In turn this allows for a smaller hot water system, reducing the installation costs of the complete installation. The energy performance of the building will improve considerably and less CO2 will be emitted. The Blue has been specifically developed for multi-storey construction and renovation projects where the highest possible efficiency must be achieved on one floor. Therefore the Blue is the ideal fit for: - apartment buildings - hotels - care centers - sport clubs - holiday parks - town houses - etc.
