Ground Source Heat Pump System UK

Geothermal Heating

Ground source heat pumps use solar energy stored under the earth or bedrock and even groundwater, this stored energy provides the heat source. They require a separate electricity supply to operate, however, due to the efficiency they can produce up to five times as much heat energy for every unit of electricity used to actually power the system. Heat pumps operational efficiency is best when the temperature difference between the heat source and the heat demand is at its smallest. Heat pumps are useful for powering under floor heating systems rather than radiator based heating systems which run at higher temperatures.

A larger hot water cylinder is required in the property, as the cylinder acts as a heat store, thus requiring more space than a conventional hot water cylinder.

Types of ground source heat pumps vary to dependent on the heating requirements of the property, whether it's an existing building or a new build property, types consist of .Horizontal loops, Vertical loops, and Slinky coils, see below for installation techniques. A ground source heat pump may be installed almost anywhere, but there must be an area large enough to lay the ground loops, or for other applications it will be necessary to drill a bore hole into the ground.

A heat pump can take low temperature heat and upgrade it to a higher, more useful temperature. If this heat comes from an ambient source, for example outside air or the ground, the use of a heat pump can result in savings in fossil fuel consumption and thus a reduction in the emission of greenhouse gases and other pollutants. Ground Source Heat Pumps (GSHPs) in particular are receiving increasing interest in North America and Europe and the technology is now well established with over 550,000 units (80% of which are domestic) installed worldwide and over 66,000 installed annually (2004). Despite increasing use elsewhere, GSHPs are a relatively unfamiliar technology in the UK although the performance of systems is now such that, properly designed and installed, they represent a very carbon-efficient form of space heating. This website provides guidance notes on the design and installation of domestic closed-loop GSHP systems to help promote appropriate and effective use of this technology. It is aimed at both specifiers and their advisors but much of the information could be of interest to a more general reader. It provides outline rather than detailed guidance, focusing on the issues to be considered when selecting systems and components and estimating system performance.

GSHPs can be used to provide space and domestic water heating and, if required, space cooling to a wide range of building types and sizes. The provision of cooling, however, will result in increased energy consumption however efficiently it is supplied. GSHPs are particularly suitable for new build as the technology is most efficient when used to supply low temperature distribution systems such as underfloor heating. They can also be used for retrofit especially in conjunction with measures to reduce heat demand. They can be particularly cost effective in areas where mains gas is not available or for developments where there is an advantage in simplifying the infrastructure provided.

What is meant by "Payback Time"?

Quite simply the payback time is determined by your initial outlay for your chosen renewable energy option (heat pump hardware and installation costs) in this case, a ground source heat pump, verses the time it takes for your savings in energy costs to pay for the green energy solution you have chosen for your project. Thereafter, you begin to save money on your utility bills. A typical low cost solution for home energy generation is a domestic wind turbine for your home, as the initial costs are lower than say the installation of solar panels or a ground source heat pump, these installations may take longer to pay for themselves. It is worth considering seeking specialist advice for any renewable energy option to determine if the solution is the right one for your needs.

Ground Source Heating is a renewable energy source. Cheaper and more affordable options that can have an immediate effect on reducing your reliance on grid electricity or mains gas is detailed in Home Energy Saving ideas.

Ground Source Heat Pumps Suppliers UK

Heat Pump Installation

A ground source heat pump can be installed with a horizontal, vertical or "slinky" type collector, for horizontal collectors the pipe is buried underground to a depth of around 1 to 2 metres. Vertical collectors are used in a bore hole which is drilled to a depth of around 50m to 200m the vertical collector is then placed inside the bore hole.The electricity for powering the heat pump and plumbing installation is simple to install. A 230V mains supply is required for the pump to operate.

Flat Plate Collector Panels

A solar panel can be used to power the heat pump to gain maximum efficiency.

Find out more about the installation and benefits associated with this type of system in a detailed analysis in Flat Plate Solar Collectors.

Horizontal Loops

The pipework is installed horizontally in trenches. The depth of the trenches will vary according to the design and soil characteristics, but is generally 1 – 2m deep. These loops require much more surface area than a vertical loop installation. Approximately 200m of pipework is required for a typical home.

Vertical Loops

Commercial projects generally utilise a ‘Vertical loop’ system. The advantage of this system is that less space is required for the installation, as the collector is located within the bore hole. Bore holes are located at approx 5m spacings and can vary in depth between 15m and 60m according to the specific design and local soil characteristics.

Slinky Coils

A ‘Slinky Coil’ is a variation of the Horizontal loop type collector. They consist of flattened coils of overlapping piping, which are then spread out and can be laid either horizontally or vertically, dependent on the site. Their advantage is that the heat transfer requires smaller volume and can reduce the length of trenches required, therefore they do not require large areas of ground space. Typically, a 10m long trench laid with a ‘Slinky’ type coil can provide 1kW of heating load.

Heat Pump Benefits

Carbon savings are nominal, but can prove positive if the system is powered by a renewable source (e.g. Solar Panel). The life expectancy of the installation can be in excess of 40 years in service.

Disadvantages

The system installation cost is relatively high, usually grid supplied electricity drives the heat pump, when heating hot water, it is necessary to have an ancillary electrical coil, a large area is required for horizontal pipe installations, the system uses refrigerants, manufacturers' may claim a COPs value (Coefficient of Performance) of 3-4, however, in practice, COPs of around 2 are more likely.

Design Criteria

Maintain maximum insulation, also, get an accurate assessment of the property's likely heat loss, ensure that you get a written statement from the manufacturer quoting the COP for the system at your designed operating temperatures (which should include both space and hot water heating), design the system for use with renewable sourced electricity for to gain maximum efficiency, survey the site to identify buried services, e.g. existing pipe work, make a record of the buried loops following installation, identify the soil type, different soil types have different heat transfer rates. For space heating underfloor heating is the best option in many cases. If retro-fitting a system use low temperature radiators. Floor tiles and slabs can store underfloor heat during off-peak electrical periods, also give consideration for space cooling.

Did You Know?

Suppliers can now provide a Photovoltaic (PV) panel adjacent to a solar panel, this type of installation can generate electricity (via the PV Panel) to power the a heat pump. This type of installation is known in the trade as a "Solar Twin". This type of system can help reduce your dependence on grid supplied electricity even further.

Building Design Products

The current design of buildings should encompass the environmental principles whilst maximising the sustainability and practicality of the building for the owner. There are many specialist consultants available in this field, find out more about Sustainable Homes.

Find companies for Building Design Products

Consideration should be given to new build homes as to the orientation and position to maximise solar gain, in this way, it can help reduce energy use, particularly in winter months. High levels of insulation should be used, and the materials used in the construction are obtained from sustainable sources.

The Sustainable Building Code helps to address these issues. The Building Research Establishment’s Environmental Assessment Method (BREEAM) also known as the BRE Ecohomes System. Assessors known as Code Assessors are specialists in this field.

Funding & Grants

The UK Government has a strategy to help reduce "fuel poverty" in Britain. Families can claim certain benefits to secure a Grant or funding for energy efficiency measures. If you claim benefits you may be eligible to receive a grant for insulation, lighting or a high efficiency gas boiler to replace Grade G heating boilers or other energy saving installation. In many cases it is worthwhile contacting your local council who provide schemes for this purpose.

Please note that some of the entitlements may change due to varying legislation, and Government sponsored schemes. See also Home Energy Saving Grants.
