Nic Wincott, UK coordinator, Neoenergy Sweden AB

Nic Wincott

Nic Wincott's interest in heat pumps goes back many years. After a brief dabble in the early 1980's predominantly with air source in swimming pools, he rejoined the industry ten years ago with the intention of walking the walk when most others were only talking the talk.

This approach has given him a sound theoretical and practical knowledge of heat pump systems and system design and in particular of ground heat exchangers of all types and sizes. Nic's collaboration with Prof Goran Hellstrom of NeoEnergy (Sweden) AB has broadened the scope of this expertise particularly into Underground Thermal Energy Storage (UTES). Well conceived, designed and executed use of UTES can not only reduce operation costs, with its associated energy and CO2 savings but frequently reduces the cost of the installation too.

Nic is active on the Training & Standards Committee where he is part of a small but dedicated team working to ensure that the GSHP industry continues to grow and flourish by delivering effective and competent installations.
