Boosting the COP of heat pumps. A high-temperature heat source for heat pumps at Howe Dell primary school in Hertfordshire is achieved by gathering energy from beneath the Tarmac-surfaced playground and storing it in an ICAX ThermalBank under the school The surface temperature of Tarmac can often reach 15 K higher than the ambient air. The temperature of the ground below the insulated foundation of the school can be increased from its natural temperature of 10°C to over 25°C during the summer. |

Upgrading a heating system is much more than just upgrading the boiler plant — Graham Williamson. |
Effective upgrading of heating systems
Published: November 2008
The heating industry has made a strong response to Government legislation to encourage energy efficiency, and the specification of high-efficiency condensing boilers has steadily increased. However, to maximise efficiencies Graham Williamson, business director of commercial heating at Ideal Boilers, stresses that installers now need to take into account more factors than simply upgrading to a high efficiency boiler.

Grant schemes to make heat pumps affordable
Published: November 2008
Providing a renewable energy heating solution in existing or new homes makes environmental sense but it can be costly. Heat-pump manufacturer Calorex and its strategic partner E.ON, has come up with the solution of delivering a fixed-price ground-source heat-pump installation package supported with grants from either the Low Carbon Buildings Programme (LCBP) or Carbon Emissions Reduction Target (CERT). This could mean, for qualifying installations, up to 85% of grant funding towards the supply and installation of ground-source heat pumps.
