Heat pumps


When nature powers industry


Gripple UK, the manufacturer of wire joining and tensioning systems, is using renewable energy and eco-friendly heat pump technology in its newly expanded headquarters


T


he employee-owned company has just completed a renovation project to extend and upgrade its factory and offices, which were officially opened just outside Sheffield in July. A key factor of the project was that it should be as


environmentally friendly as possible and renewable energy company Energy Jump was brought on board, identifying the adjacent River Don as a key heat source. The river contains heat emitted by a nearby steel


factory, so Energy Jump fitted Stiebel Eltron heat pumps to extract the heat from the river. Three WPF 66 heat pumps and one WWK 300AH now provide all the heat needed for the 2,200m2


Gripple UK’s newly expanded headquarters of factory space and


office buildings, distributed through Jaga unit heaters, underfloor heating and oversized radiators. The system utilises Gripple products, as the heat pump pipework is secured on its industrial hanging system. Gordon Macrae, special projects manager at


Gripple, said: “This is a great example of industry utilising the power of nature. We got rid of the inefficient old gas heaters and have provided comfort to our employees, while remaining sympathetic to the surrounding environment.” The eco credentials of the heat source is reflected in other areas of the project; Energy Jump also installed a 116KW solar PV system while a green wall has been created using hydroponics (fish excrement as a plant fertiliser). Energy Jump and Stiebel Eltron worked closely with the Environment Agency to ensure standards were met and that the


River Don salmon fish pass that was being constructed at the time was not disturbed. Rob Samuelson of Energy Jump said: “We’ve


transformed a cold and draughty space into a comfortable working environment in a matter of weeks. Thanks to the swift pump sizing and support given by Stiebel Eltron, the green credentials of Gripple’s UK plant are very impressive.” Stiebel Eltron UK managing director, Mark McManus, said: “We are pleased to have worked so closely with Energy Jump, Gripple and the Environment Agency on this project, to be able to reassure the client that its approach to nature was respected. This was the brief given by the employees themselves, so could not be compromised. The end result is a much more efficient, aesthetically pleasing and sympathetic system.”

GSHPA LAUNCHES CO2 CALCULATOR AND GOOD PRACTICE GUIDE


recently held in Stone, the first being a realtime CO2 calculator, the second a revised and user- friendly Environmental Good Practice Guide for Ground Source Heating and Cooling. Prior to the opening of the Expo, the GSHPA held its AGM and welcomed Mark Burton from Vaillant and David Jones from Hafod Renewables as newly-elected council members. • The new realtime CO2 calculator is an app displaying the realtime carbon intensity of the UK


T 16 October 2017


he Ground Source Heat Pump Association (GSHPA) has launched two new tools at this year’s Ground Source Energy Expo 2017


electricity grid. This value is used to calculate CO2 emissions from ground source heat pumps (GSHPs) using power at that moment. It is updated every half an hour and


illustrates how much lower carbon emissions are from ground source systems compared to burning fossil fuels. The CO2 issued by a GSHP powered solely from green electricity is, of course, zero.


This CO2 emissions calculator, sponsored by Geoscience, shows the CO2 issued if your GSHP uses grid electricity. The values for GSHPs using grid electricity have fallen rapidly as grid


electricity generation from coal has been largely replaced by gas and generation from renewable power technologies. • The Environmental Good Practice Guide for


Ground Source Heating and Cooling was orignally published in 2011 by the Environment Agency to provide information, advice and guidance to prospective users of ground source energy, their consultants and contractors. This has now been significantly updated by the


GSHPA and focuses on good practice for open and closed loop GSHP systems. A copy may be obtained by contacting info@gshp.org.uk.
