ENER-G delivered a solution that combines two low carbon technologies – a ground source heat pump system and a combined heat and power (CHP) unit - as part of the eco-friendly design brief set by Interserve, which was contracted by Worcestershire Primary Care Trust to build the £17.7 million new hospital.

The 24-bed hospital will utilise renewable geothermal energy for heating, cooling using ground source heat pumps to harness solar energy absorbed by the earth. It will also generate low carbon electricity and hot water using highly efficient combined heat and power (CHP) that will meet a significant proportion of the building’s needs.

“We are very proud that our state-of-the-art hospital will be so eco friendly. Reducing our carbon emissions will also save us money in the long term, which means we can spend our money where it matters, on patient care.”

The ground source system comprises of 25 boreholes and two heat pumps with combined capacities of 125kW for both heating and cooling. The combined heat and power (CHP) system is a reciprocating gas engine rated at 33kW of electrical output that will generate 55kW of useful thermal output for the building and the ground loop for the heat pump.

By generating its own green power, the hospital is projected to save on its energy bills, and reduce its carbon emissions by 15 tonnes per annum, equating to the environmental benefit of planting 1,500 trees.

The new hospital, at Seaford Court, Malvern Link, will include in-patient and out-patient facilities, x-ray and ultrasound, day rehabilitation and therapies, palliative care and visiting mammography and MRI scans. A minor injuries unit will transfer from the existing hospital, offering increased capacity.

The CHP reduces greenhouse emissions drastically by capturing the heat output that is wasted in conventional power generation. CHP electricity is around one third of the price charged by conventional UK suppliers and cuts carbon by around 20%.

Turnkey delivery of individual heat pump projects are delivered by ENER-G’s unique in-house resources including its own specialist designers, drilling rigs, drilling technicians, mechanical installers and project managers.

ENER-G has won official certification for its expertise in renewable heat pump technology. The Approved Contractor certificate recognises the quality of ENER-G’s design, supply, and installation of ground source heat pumps, in line with exacting technical standards set out by the Micro generation Certification Scheme (MCS).
