Ground Source Heat Pumps to combat fuel poverty

A recent retrofit programme by Taking Trent & Dove Housing, which replaced electric heating with ground source heat pumps in 133 rural properties, presented the compelling case for shallow geothermal in social housing.

Every winter around 30,000 people die in the UK because they are too poor to heat their homes. At a recent event, Trent & Dove Housing and Kensa Heat Pumps provided step by step advice backed up with case studies to help housing associations combat fuel poverty in rural and off gas grid housing stock through the installation of ground source heat pumps.

“We have seen an immediate saving on tenants energy bills – many of whom are elderly and vulnerable – as a result of our upgrades programme, which we see as being key to reducing fuel poverty and excess winter deaths in our stock,” Steve Grocock, Director of Property Services for Trent and Dove Housing said. “The fact that 30,000 deaths nationwide every winter are deemed ‘preventable’ (according to the Office of National Statistics) is just unacceptable. Small measures such as replacing night storage heaters with more efficient and affordable ground source heat pump systems can make a big difference – in fact, in some cases, it is the difference. We should all be doing this – what are you waiting for?”

The results of the scheme are ground-breaking: with a potential tenant annual running cost reduction of £62,000, tenants are saving on average between £350 and £750 on their fuel bills per year.

Over 600 storage heaters were removed in total, with 10km of boreholes drilled and 32km of pipe installed. Working to the ambitious four month timescale, 20 installations took place per week at the peak of the operation with a heat pump being installed every 4 hours.

Scotland: Geothermal energy projects awarded quarter million

Almost a quarter of a million pounds of funding has been awarded to five feasibility projects across Scotland that will investigate how the thermal energy in the ground can be used to heat homes and businesses.

A total of £234, 025 has been awarded to projects targeting sites in Fife, West Lothian, North Lanarkshire and Aberdeenshire that will explore the technical feasibility, economic viability and environmental sustainability. The awards have been made from the Scottish Government’s Geothermal Energy Challenge Fund, supported by the Low Carbon Infrastructure Fund, the first strategic intervention established under the new European Structural Funds Programme.

They are the first support for geothermal projects in Scotland following a 2012-2013 study which identified significant potential for geothermal heat as a renewable heat source. Heat is estimated to account for over half of Scotland’s total energy use and responsible for nearly half of Scotland’s greenhouse gas emissions. The projects are an important step towards demonstrating how geothermal energy could cut the estimated £2.6 billion a year spent on heating by householders and the non-domestic sector.

Cardiff to trial groundwater heat pump technology for district heating

City of Cardiff Council is to undertake a £250,000 trial of groundwater heat pump technology to see whether its groundwater resources will support a larger scale district heating scheme for the city.

The partnership project between the council Cardiff-based business WDS Green Energy and the British Geological Survey will take the temperature of the water stored underneath the city, monitor heat lost from underground structures and then design and build a prototype portable testing module, based on ground source heat pump technology.

Workshop: Developing Sustainable Energy in your City? The Heat Under Your Feet is a Solution

On Tuesday 16th of June, a workshop organised in the framework of the Regeocities project will explain in depth and with practical examples how shallow geothermal energy can be developed to make cities smarter.

The event, taking place during the European Sustainable Energy Week in Brussels (EUSEW), is for public authorities, planners, architects and the building sector. The workshop will explore the potential of shallow geothermal energy for smart cities and smart rural communities, and the key role that ground source heat pump installations could play for sustainable heating and cooling in buildings.

During the workshop, a series of presentations, case studies and debates will cover:

  • Recommendations on regulations: Current forms, best practices, and tools for local authorities.
  • Public acceptance: What do the public know and think about GSHPs and what is the impact of this understanding?
  • Financing: How can GSHP systems be financed?
  • Energy Planning: Information for local authorities on the role of shallow geothermal in their energy strategy and urban planning.
  • Training: What information and training is available for local authorities and installers?

Global geothermal heat pumps market growth driven by rising electricity and oil prices

The global geothermal heat pumps market is expected to have a 13.1% compound annual growth rate (CAGR) from 2014 to 2020, reaching $130.5 billion by the end of 2020, says new market research report from Transparency Market Research.

According to the report, rising electricity and oil prices are shifting consumer preference towards cost-effective energy substitutes. The highly reliable nature of the system and easy financial options for consumers are fueling demand for geothermal heat pumps. On the other hand, faulty installations and wrong estimation of pump size are factors curbing global demand.

North America and Europe lead the global geothermal heat pumps market, the report also says. European countries such as France, Germany, Sweden, and Switzerland are mature markets and have experienced a steady decline in installed capacity in the last few years

The report analyses regional markets for North America, Europe, and Asia Pacific, featuring also a detail regional segmentation with market growth forecasts for the 2014 to 2020 period. It includes key market dynamics affecting the demand for geothermal heat pumps globally, including market drivers, market restraints, and market opportunities.

The Heat Under Your Feet: Promoting geothermal heat pumps

The Heat Under Your Feet is a European campaign aimed at promoting the use of geothermal heat pumps and tackle some of the challenges and barriers that leave the potential of this technology unexplored or underdeveloped in many European countries. It is launched as part of the EU-Funded ReGeoCities project.

The heating and cooling sector for buildings is today, for the large majority, dominated by the use of fossil fuels such as natural gas and heating oil. This means it is contributing heavily to costly fossil fuels imports, exposure to price volatility and security of supply, and production of harmful greenhouse gas (GHG) emissions.

Geothermal heat pumps are the perfect solution to replace fossil fuels and reverse these unsustainable situation. Their wide range of application, their efficiency, their reliability, all strongly contribute to provide affordable heat, to reduce emissions, and to save primary energy.

Despite their advantages, the results of the ReGeoCities project indicated a widespread lack of awareness among the general public, public authorities and builders regarding geothermal heat pumps, suggesting that an informative campaign was highly needed.

The Heat Under Your Feet aims to address such shortcomings and fill the awareness gap, by serving as an information hub and a reference point.

On the campaign website, it is possible to find information on how the technology works, the benefits it can achieve, and useful factsheets available for download. In a project showcase, examples of best practices illustrate how geothermal heat pumps, thanks to their highly efficient and highly versatile nature, are the perfect technology for sustainable buildings that look at the future. More resources, like case studies and useful tools on financing and regulation, will be following soon.
