Ground Source Services

Ground Source Heat Pump Thermal Response Test and Consultancy for borehole sizing by independent consultants – we work UK wide.

Our onsite testing and design services include: borehole sizing; thermal response tests and detailed geological and engineering calculations 

Correctly sizing ground exchange conditions allows, in many cases, a project saving in borehole drilling costs. It also allows correct design for connections and network design which is essential for successful building service projects.

Ground Source Heat Pump Design

Geological Report and Borehole design

Let us help with your detailed ground source design. Once a set of initial geological  calculations has been done we can find the optimum balance between energy extraction and recharge rates in the ground.

We then can then specify number and depth of boreholes and pattern of drilling to minimise your capital expenditure. We do vertical, horizontal and water extraction collector designs. 

Thermal Response Test - Ground Loop

Often overlooked a good ventilation design goes hand in hand with a comfortable building.  A good design will take into account flow rates and duct sizing, duct loss and system balancing to not only achieve a good level of comfort but also reduce energy, noise and condensation issues.

How We
Can Help

Traditionally heating/services were a standard work package handled by the trades and architects but buildings, regulations and the needs of the client have become more complex over time, and rightly so. Heating is integral to the comfort and well-being of your home/work and is only now been given proper consideration in the build. Also, often it can have the largest impact on operating cost for you in terms of bills and carbon impact over the long-term. In addition, there are a multitude of options available with renewable technologies in a fast-changing market. There can be a considerable cost benefit to have input from specialist independent building service engineers at several stages.
