Dales Water

For heating and air conditioning the rock strata or groundwater may be used as a constant temperature source to cut fuel bills in combination with heat pump systems, ideal in those crcumstances where ‘green issues’ are being considered or where other heating solutions are expensive. Dales Water has undertaken the appropriate drilling and asociated installation in individual dwellings to large commercial developments. Several tyes of heat source exist, which is choosen depends on site specific information:

Closed loop borehole:

A single (or several) borehole is drilled, the depth of the hole and equipment required reflects the nature of the site / what it is going to be used for (i.e.: a house will require a smaller and less holes than a office block). A single or double loop pipe is placed into the borehole and and an anti-freeze mix passsed through and brought back to surface before being passed through a heat exchanger and re-circulated. A special bentonite mix is used to aid the heat recovery at depth.

 Open loop borehole:

In our experience this option provides the best heat and financial return and often this can be combined with a standard abstraction borehole.  Water is not re-circulated, as with a closed loop, but used water is put either into a secondary exhaust borehole or into a watercourse.  

Trenching:

Dales Water are not actively involved in the provision of trenching geothermal systems but  it is similar to the closed loop systems, being horizontal rather than vertical.
