Ground source heat pumps

We install boreholes for ground source heat pump systems for both heating and cooling.  For each kW used to power the system, it can return up to 4kW of energy - making this renewable energy source cost effective.

For the ground source heat pump to operate, you need a heat collection system in the ground.

We install a vertical ground source heating system by drilling one or more boreholes. The vertical system eliminates the need to dig extensive trenches and reduces the level of mess and disruption to your garden or land.

This ground source heat pump vertical borehole solution is efficient, affordable and neat.

Benefits of ground source heating systems

  • Huge financial savings - slash your energy bills
  • The electricity used to power the heat pump produces up to 4 times its energy output from the ground source
  • You're making an investment in renewable energy and creating a sustainable heating system
  • A reduction in CO2 emissions

Utilising a borehole is the most efficient way of extracting heat from the ground.

We have been installing boreholes for ground source heat solutions for commercial and domestic clients across the United Kingdom for many years, and have extensive experience in this field of renewable energy.

Geothermal heating - prognosis

A prognosis for ground source heating assesses the ground’s capacity to deliver heat to a heat pump.

For ground source heating and cooling this prognosis is called a geotechnical report or ‘geo-report’ 

It is a detailed report about the geology of a drill site; it identifies any drilling hazards or other issues that need to be considered for the design of your borehole.

It helps us calculate the length of the ground loop too.

The reports are based on geological interpretation by a chartered geologist using data from maps and national archives and databases.

The cost of a geo-report 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

Heat collection systems

For a heat pump (geothermal) to operate, it is necessary to install a heat collection system in the ground.

There are two main ways to gain access to ground heat:
horizontally or vertically

Horizontal heat collection system

A horizontal heat collection system involves digging a trench 1 or 2 metres deep, then burying pipes.

A wide trench needs to be dug, and plastic pipe, coiled into ‘slinkies’ is buried. On average 10 metres of trench is needed for each kilowatt of power.

This is likely to mean digging at least 100 metres of trench work – a considerable earthworks exercise. This can be an off-putting, expensive and disruptive collection solution.

We don't recommend it.

 

Vertical heat collection system

We use a vertical ground source heat collection system.

This simply involves drilling one or more boreholes straight down into the earth.

The vertical system eliminates the need to dig extensive trenches and reduces the level of disturbance, delivering overall consistency and efficiency - without making a mess!

Utilising a borehole is the most efficient way of extracting heat from the ground. A boiler-sized heat pump is then carefully installed by our in-house NICEIC electrician and your geothermal energy supply is up and running.

Why boreholes are the best source of ground heat…

Borehole - or vertical ground source heat systems bring major advantages including:

Far less disruption: they eliminate the need to dig and re-cover massive trenches. Trenching is a major exercise, and in many instances – for most domestic properties, and many commercial premises – the space is simply not available.

Better consistency and efficiency: unlike trench systems, the underground temperature is consistent and heat is extracted more efficiently.

How ground source heating works

Closed loop heating, ventilation and air conditioning (HVAC) systems are becoming increasingly important in the quest for improved energy savings and safety.

These systems are designed to transfer heat through circulating water for air conditioning, heating or process applications - here's how they work:

How do ground source heat pumps work?

Borehole cooling and heating pumps extract the heat in the ground or water and transfer it to a building for space and water heating.

To cool the building in hot weather, heat is returned to the ground or water.

For optimum function of an HVAC system, the quality of borehole construction is a key consideration.

Our experience of drilling boreholes, and our emphasis on quality control and environmental care, are key factors in ensuring your geothermal energy system meets your needs.

Why choose renewable geothermal energy?

Energy costs continue to rise, and there is an ethical move to reduce the use of carbon-based fuels
Legislation is helping drive things forward, Part L of the Building Regulations sets higher standards for energy conservation.

Renewable energy can bring attractive economic benefits.  You may benefit from renewable heat incentives in the UK too. And geothermal energy for ground source heating and cooling can deliver up to four times more heat than the electric energy used to produce it!

Ground source heating is proven technology, systems have been successfully and extensively used worldwide, and the benefits demonstrated.

These benefits include environmental and economic factors due to very low operating costs compared to fossil fuel systems. CO2 emissions are reduced.

Harnessing geothermal green energy

The ground can be used either as a source of heat or to provide cooling. Underground temperature is constant, so air temperature has no effect on a system’s efficiency.

Either way, heat is taken from or disposed of into the ground via boreholes. Heat is made available to the building using a heat pump.

Configurations range from simple under floor heating and domestic hot water, to reverse cycle pumps for heating and cooling, and sophisticated systems for simultaneous heating and cooling.

Vertical open and closed loop systems


Vertical closed loop systems:

These incorporate one or more boreholes with a single U-shaped high-density polyethylene (HDPE) plastic pipe loop that circulates water with an antifreeze, usually brine.

The finished borehole is sealed with special heat-conductive grout from top to bottom.

The green energy solution extracts heat from the borehole and delivers heat to the heat pump.

Heat is extracted from the water to heat your business premises or home, before the water is returned to the ground.

 

 

Vertical open loop systems:

These abstract groundwater which is circulated directly through the heat pump.

Due to the conductive nature and specific heat capacity of groundwater, an open loop system can deliver a large amount of energy from a single well or borehole.

Water is abstracted from the borehole, passed through a heat exchanger/pump system, and then either used as part of a grey-water supply system, or discharged to a surface water system, or back underground.

A second borehole may be required if discharge to groundwater is used. Both abstraction and discharge require consents and licences which we can help you obtain.

A borehole producing 10 cubic metres/hour can supply 80kW. Sometimes energy loadings in excess of 500kW are possible.

We have extensive experience installing vertical open and closed loop systems. 

What is a heat pump?

The easiest way to understand how a heat pump works is to think of it like a fridge, but in reverse.  It takes the heat out of groundwater and concentrates it for use in the building. The opposite of a fridge which takes heat out of the appliance and dumps it into the air.

Are there any disadvantages with ground source heating?

The use of the ground as a source of heating or cooling has some disadvantages or risks. With closed loop systems, in major schemes the largest risk is excessive heating or cooling of the ground around the boreholes. This can occur if they are too close together, or too heavy a demand is put on the system.

This would affect system efficiency – but is most unlikely to be a problem with domestic and smaller scale projects under 50kW.

In open loop systems, demanding too high a volume of water from a borehole can exhaust its supply. Otherwise, thermal breakthrough can occur, where the intake pulls warmed water back in. Then there are thermal plume migration issues too— an impact on other boreholes, or the surrounding environment.

In short, for open loop schemes and closed loop schemes over 50kW, specialist advice should be sought…the team at WB+AB Morgan can support and advise you.

While existing buildings can often be successfully adapted to use ground source energy, the most efficient systems are designed into the building from the start. Liaison between building and systems designers, hydrogeologists and thermo-geologists will ensure that any risk factors are taken fully into account and eliminated.

Something for nothing is always appealing, and having paid for the installation, you’ll reap the benefit of low-priced heat for years to come… just ensure you employ experienced solutions providers to ensure you reap the benefits fully - and encounter none of the potential issues… speak to WB+AB Morgan today.
