An independent hydrogeological survey (a prognosis) is an essential requirement before any drilling commences. The survey provides an indication of the underlying hydrogeology – detailing the nature of the ground to be drilled, the likely depth at which water will be found and an indication of water quality, enabling the borehole design to be properly specified. Whilst the prognosis is not a guarantee of success it will highlight any risk at an early stage.
Water or heat?
The requirements for water and for heating boreholes are in many respects different, and will require a specific form of prognosis:
- A prognosis for ground source heating will concentrate on the ground’s capacity to deliver heat to a heat pump
Ground source heating + cooling georeport
What is a Georeport? A detailed Georeports allows the geology of a drill site to be identified, drilling hazards to be indicated, and the design length of the ground loop to be calculated.
The reports are based on geological interpretation by a Chartered Geologist using data from maps and national archives and databases. They are written in a way that we as drillers and customers will understand them.
The costs of a Georeport is based on the size of heat pump:
- Less than 15kw £540.00 incl. VAT
- 15kw – 30kw £780.00 incl. VAT
- 30 – 45kw £1,200.00 incl. VAT
- Over 45kw Price on application – Call 01544 267980 to arrange a report.
