ABOUT US
H.D. Services Ltd. Is a small family run company based in Buckinghamshire. We have been constructing water supply and soakaway boreholes and installing our own bespoke designed sewage treatment systems in South East England for over 30 years. In 2009, H.D. Services expanded into the renewable heat market when we identified the link between the water we drill for and the ability to use this water as a heat source for renewable heating. Having partnered with a British based heat pump manufacturing company, we have been installing Open-Loop Ground Source Heat Pumps since 2010.
A fully MCS accredited company, H.D. Services Ltd. aims to provide the highest quality Open-loop Ground Source Heat Pump installations available in South-East England. In 2014 we were awarded a High Commendation at the national Energy Efficiency and Renewables Awards for our work in the South East.
H.D. Services Ltd were approached in 2011 by Acanthus Developments and asked to tender for the installation of three water supply boreholes to serve each of three prestige properties. Closed loop ground source heating was being considered, however the availability of a reliable ground water supply from the chalk aquifer resulted in the installation of three open-loop heat pumps. The development went on to win a Green Apple award in recognition of the Sustainable Nature of the development and the Architectural Design Excellence of the properties.
Using the postcode of the site to assess the hydro-geology, a quotation was submitted for the construction of both the water supply borehole and soak away at each location. The deal was that both the water supply borehole and soakaway were constructed and water pumped from one to the other to prove the worthiness of both before and payment was requested. It was several months later, once the construction of the properties had been completed that the heat pumps could be installed and commissioned. Each installation is covered by a 5 year workmanship warranty and annual maintenance contracts have been offered.
The boreholes were drilled using a cable-percussion rig – the method preferred by the Environment Agency when drilling into the chalk aquifer. Borehole logs were submitted to both the British Geological Survey and Environment Agency to protect the abstractions from derogation by a third party.
From the experience gained on the contract, plumbing and electrical guides were designed and are handed to the client for distribution to their contractor. These have been written by a fully qualified professional and in conjunction with the heat pump manufacturer. They inform the heating distribution system installers of both the plumbing requirements and the electrical requirements of the heat pump. This ensures that while work is continuing on the build, those on site have the information to hand regarding system requirements which provides confidence that all required connections are in the correct location making the installation and commissioning of the heat pump a straightforward process.
Work was completed in late 2012 and all three of the heat pump installations were commissioned successfully.
Due to the nature of the development, only one of the properties was considered eligible for the dRHI as the client now resides there. Although the other two properties are technically RHI eligible in that they have been installed with the RHI in mind and are MCS compliant, as they were built for resale they are rightly deemed ineligible for the incentive.
