Lowering the carbon and energy consumption of essential infrastructure

 

Our latest project

Watch the short video below to see how we helped Eden Geothermal deliver renewable heating for the Eden Project by laying a 3.8km heat main from the borehole to the plant room.

 

What is a Ground Source Heat Pump?

A ground source heat pump is a low carbon heating system that utilises the solar energy stored in the ground. This energy is at low temperature which is elevated in the GSHP refrigeration circuit to a usable temperature. This can then supply heat to a building or process as well as hot water. GSHPs can also provide cooling by rejecting heat back into the ground.

Ground source heat pumps can provide temperatures up to 65°C. As well as heating buildings of all sizes and ages, they can also deliver active or passive cooling. Ground source heat pumps can produce:

  • Hot water
  • Heating
  • Cooling

 

How do they work?

Ground source heat pumps work by absorbing energy from the ground and compressing the low-grade energy into high-grade heat. They then deliver the heat through a heating distribution system, such as radiators or underfloor heating, for reliable heating and domestic hot water through the seasons.

 

Ground source heat pumps can produce:

 

What are the benefits?

With the drive to reduce carbon emissions and to become carbon neutral or net zero by 2050 the need for a well-designed ground source heat pump system is paramount and benefits from:

 

Maximum efficiency from little input

Providing 400 kW of heat energy for every 100 kW of electrical energy used, a geothermal ground source heat pump system is shown to be over four times more efficient than conventional fossil fuel heating and cooling methods.

 

Our group of specialists

What can we offer?

As well as offering a free, no-obligation survey and quotation, OnSite provides and installs the necessary pipework to connect the borehole to the heat pump. Using the latest technology and expert teams, we can install and replace the head works to boreholes and abstraction platforms, lay the interconnecting pipework to the borehole arrays, install ambient loop networks and secondary pipework distribution.

 

Why OnSite?

We carry an extensive stock of pipe and fittings for the full or partial renewal of all types and sizes of Pipelines.

Our specialist teams are dedicated to pipeline installation and replacement, and equipped with the latest and safest equipment for excavation, trench support and the backfilling and reinstatement of excavations.

We are committed to continued improvement in project design, execution, and completion, combining this expertise with innovative technological applications such as the latest project management software.

 

The right pipes

OnSite has extensive experience of laying all types of pipework in trenches for GSHP Installations including HDPE Headering works from boreholes to plantroom, HDPE Ambient loop pipework, Pre-Insulated Cross Linked PEX distribution pipework and pre-insulated welded steel pipe.

 

Covering a wide variety of sectors

We have undertaken hundreds of individual pipeline installation and replacement projects for the following:

  • Water companies
  • Local Government
  • Industrial
  • Commercial
  • Environmental
  • Retail clients

 

Unparalleled experience, knowledge and training

From initial consultation through to onsite co-ordination, our project managers have decades of experience in the safe and efficient delivery of successful engineering and construction projects.

Our teams are highly trained including:

  • ‘IOSH’ Working Safely
  • Street-works Accredited (NRSWA)
  • Training in trench support and working in deep excavations
  • We operate Management Systems certificated to BS EN IS9001, BS OHSAS 18001 and BS EN ISO14001
  • Where necessary, we will liaise with Water Companies, Highways Agency and Local Authority Departments
  • ‘Watermark’ Accredited
  • Constructionline and CHAS registered
