Taff’s Well, Wales


In a unique installation project for Kensa Contracting, the historic Taff’s Well – Wales’ only thermal spring – was used as a heat source for heat pump systems in Ffynnon Taf Primary School and the pavilion at Taff’s Well Bowling Club, near Cardiff. Kensa designed a complex but effective open loop water source system and oversaw innovative horizontal drilling solutions in the installation of the underground pipework.

Water source systems are highly efficient, as water has a higher heat transfer rate than the ground. The primary school benefitted from the high heat capabilities of Kensa’s Q heat pumps, whilst the bowls pavilion is heated by the efficient Kensa Evo.

Kensa designed an open loop system to harness the heat energy provided by the flow of warm water from the spring. Unlike traditional ground source or closed loop water source heat pump systems, that use pipework circulating a heat transfer fluid to harness the heat, in this case, water from the well is extracted via a pump and used directly within the system.

Key Facts

  • Project completed on behalf of Rhondda Cynon Taf County Borough Council
  • Open loop system using Wales’ only thermal spring, Taff’s Well, as a heat source
