A heat pump concentratesthis heat and transfers it throughthe domestic heating system in thesame way as a conventional boilerproviding both central heating andhot water.It is so efficient, it can provide theheat needed for a well insulatedhome at around 50% of the cost ofa conventional oil fired boilersystem3

12/7/2008Why GSHP?HeatGen • Low running costs and CO2 footprint• Unobtrusive – not visible externally• No flames or combustible gases• No emissions or noise nuisance• No fuel handling/storage requirements• No fire/explosion hazard• Only requires electrical infrastructure• Long lifetime• No reduction in performance over timeScope of Works HeatGen •Geological Assessment•Ground Loop Design•Drilling / U-tube / Grouting•Horizontal pipework (+/- trenching)•External Enclosure (optional)•Ground Source Heat Pump•Ground side pipework•Testing & Commissioning4
