Chartered surveyor Powis Hughes has tackled the problem of rising oil costs to heat its premises, a converted 50-year-old barn in Berkshire, with the installation of a 20 kW ground-source heat pump. The Dimplex heat pump was installed by GHE and draws energy from eight trenches 50 m long, a metre deep and a metre wide in a large field next to the barn

A reversible hat pump and a thermal wheel are key features of Flakt Woods ventilation system installed as part of the refurbishment of the Arundel Building at Sheffield Hallam University. The system can supply up to 2.5 m3/s of conditioning air into a VAV (variable air volume) system and incorporates inverter-driven compressors. It replaces a natural-ventilation system.

So great are the benefits of a larger ∆T in hydronic heating and cooling systems that the issues posed to the commissioning process are well worth addressing. Chris Parsloe explains.

Gas-fired absorption heat pumps now supply most of the space heating and support the DHW system at a care home in Banbury. Ken Sharpe was given the chance to look at the project.

Solar power will prosper without subsidies in the UK as early as 2020, especially in the commercial rooftop market, according to a report* that uses the experience of Germany to project the outlook for solar costs in Britain and impacts on utilities. During 2015, solarPV will overtake both gas and coal to become the number-one power-generation technology in terms of annual installations.

Feedback from Hamworthy’s recent series of continuing professional development (CPD) presentations suggests that there is a lack of awareness in our industry about the pending Energy related Products (ErP) Directive. Mark Goodacre of Hamworthy Heating sheds light on what will be changing and the potential impact this will have for specifiers, consultants and contractors.
