Heat Pump Solutions

Horizontal Ground Source Heat Pumps

Energy is gathered from the top layers of the ground, which has residual warmth from the sun.

GOOD FOR:

  • Larger gardens or areas of land
  • Any climate but less suited to very cold areas
  • Comfort cooling extracted directly from the ground loop (passive cooling)
  • A reversible heat pump can provide active cooling as well as heating

Borehole Ground Source Heat Pumps

Boreholes allow you to install a GSHP system in properties with a small amount of land.

GOOD FOR:

  • Smaller gardens or areas of land
  • Any climate
  • Comfort cooling extracted directly from the ground loop (passive cooling)
  • A reversible heat pump can provide active cooling as well as heating

Lake/Pond Ground Source Heat Pumps

Like land, large bodies of water retain heat which is replenished from the bottom of the lake and also from the sun.

GOOD FOR:

  • Lakeside properties
  • Any climate
  • Potential for comfort cooling directly from the lake (passive cooling) depending on lake temperatures and location.
  • A reversible heat pump can provide active cooling as well as heating

Air Source Heat Pumps

Energy in the outside air can be extracted using a heat pump and transferred into a property via a circuit heated by a compressor system. UK air temperatures are suitable for the use of ASHPs, particularly further south.

GOOD FOR:

  • Warmer regions, for efficiency and effectiveness
  • Small to medium sized properties generally

Is my COMMERCIAL PROJECT Suitable for a Heat Pump System?

Hex Energy has installed heat pumps in many commercial applications and there is a solution to match most requirements. Once you have contacted us with your requirements, we will attend site and assess each individual project on its own merit and be able to make an assessment of which type of heat pump solution is best. If you are completing a new build or a large refurbishment it is the perfect time to remove the need for burning carbon and help with achieving your businesses carbon reduction goals.

Commercial Case Studies

Kering Group

Kering’s offices Mayfair, London, underwent extensive refurbishment under the watchful eye of ESA of Milan The system installation involved feasibility, design and installation of the first ever mono bore open loop system which uses one well to abstract from and re inject the source water to using well packers to create vertical separation in the aquifer.

Litecast

Litecast of Nuneaton have developed a new purpose built floor bean mould factory to be the lowest carbon facility of its kind, built by A & H construction. Hex designed and installed a totally bespoke GSHP system for the mould bed heating and to heat the concrete batch water to reduce additives and cement content saving thousands of pounds in material costs alone.

NAMRC

Working with BAM construction and Silcock Leedham, a district network was proposed for buildings at the Sheffield Universities Nuclear Advanced Manufacturing Research Centre (NAMRAC). The project involved the drilling and headering of 52 boreholes 150 m in depth through a former open cast coal mine and in to the bedrock below.

Is my Residential Project Suitable for a Heat Pump System?

For a ground source heat pump system, you will need outside space; about twice the surface area of the property. If you have a lake or pond, a water source may be the solution or consider an air source heat pump system if you don’t have the space, don’t want to re-landscape or you live in an urban area.

The level of insulation will also impact energy efficiency offered by a heat pump system.
Properties which have high energy efficiency standards are ideal for the installation of heat pumps.

Your current heating and hot water source also has an effect on the financial rewards of renewable heat systems. For example, if you are replacing an electric, liquid gas or solid fuel system with a heat pump, the financial benefits are likely to be reasonably high.

If you are considering replacing the gas boiler in your property, a heat pump system may be slightly more expensive to run unless particular attention is paid to ensuring maximum efficiency of the heat pump in the heating system by using best practice radiator / underfloor heating design. However, if gas prices continue to go up, as expected, heat pumps will become the cheapest as well as the lowest carbon form of heating available.

Residential Case Studies

Central London

An open loop ground source system was underperforming until Hex Energy designed a unique solution to enable water to be taken out from – and replaced into – the same well, fully supported by the Environment Agency.

Quarry

This customer approached us for a heat pump using horizontal trenches. When we visited the site it was a disused quarry, with rubble and waste making conditions difficult for creating good trenches. Instead we suggested taking advantage of the large quarrying hole filled with ground water, as this lake seemed to be a more viable source of energy for a Ground Source Heat Pump.

Saving Running Costs

Over the years this customer had operated the system, the original installer had replaced the heat pump several times due to power issues, and had even (at his own expense) installed 3 phase power thinking that bigger was better and that 3 phase would stop the lights from flickering when the heat pump came on. Finally, the heat pump failed completely and the customer was ready to ditch the technology entirely and opt for LPG or oil, or have another go at a ground source heat pump.
