The following standards and guidelines represent major initiatives to drive up quality standards in the Ground Source Heating Industry.
Consumer confidence in our industry is essential to its long term growth and profitability.
Unfortunately, as with many emerging and "fashionable" technologies, the standard of implementation across the industry and country is, at best, variable with some companies cutting corners and botching installations, sometimes through simple ignorance or inexperience, sometimes simply to make a fast profit.
There are though, companies, like ours, who wish to achieve the best possible standards for the client. These are the companies that will strive to adopt the new standards.
Should you wish to obtain government funding contributions for your geothermal heat pump project, it is essential that you read carefully, and adhere to, the standards referred to below. Failure to do this will simply result in your application for government funding being refused.
Synergy Boreholes and Systems Ltd. endeavors to adhere to the highest standards of operation when drilling, installing and commissioning geothermal borehole arrays.
The most relevant passages of the MIS 3005 standards; Borehole array design parameters, materials, test procedures etc. are given here (Starts on page 19 of MIS 3005)
4.2.11 Designing ground heat exchangers is a complex engineering problem. If insufficient information is available to accurately design a ground heat exchanger, the installer shall adopt a conservative approach. For systems which require the heating capacity found in section 4.2.1 c) to be ≥30kW or incorporate ground loop replenishment through cooling or otherwise, the installer should undertake the design process making use of specialist recognised design tools and/or seek advice from an expert.
Synergy Note: Below 30 kW heat pump capacity, it is permitted to estimate borehole requirement using the tables provided in the MIS 3005. Above 30 kW you really need a professional design by a qualified and accredited designer, Synergy will be glad to help you with this.
4.2.13 An accurate assessment of the temperature of the thermal transfer fluid entering the heat pump. The temperature of the thermal transfer fluid entering the heat pump shall be designed to be >0 Deg.C at all times for 20 years.
The first to be published is the GSHPA Vertical Borehole Standard which covers Closed Loop Vertical Borehole: Design, Installation & Materials Standards under the following headings:
