WHAT IS A GROUND SOURCE HEAT PUMP?

A ground source heat pump extracts low-temperature solar energy that is stored in the ground or water. If you are looking for a heating system for your home that uses renewable energy, this is one of the most effective systems that you can install. It works by harnessing the low-temperature energy and converting it into a temperature that heats your water and provides warmth for the building. Ground source heat pumps do this by using pipework that is buried in the ground, compressing the energy into a higher temperature. It is one of the most effective renewable heating systems that you can install at a property. A ground source heat pump will provide the building with 100% of its heating and hot water needs throughout an entire year – it is a genuine, effective alternative to traditional fossil fuel heating systems.

WHAT APPLICATIONS CAN GROUND SOURCE HEAT PUMP BE USED FOR?

A ground source heat pump can be used for a variety of applications. You might be under the preconception that a renewable energy source like a heat pump is only available for installation in new build properties. This is not the truth. Both new and existing properties can reap the benefits of affordable, efficient, low-carbon options for heating.

A ground source heat pump can be installed in new build homes, existing homes, schools, holiday cottages, listed buildings, in both rural and urban locations. Once you realise that there is an affordable low-carbon alternative out there for any property type and location, it opens up a whole host of possibilities for a homeowner or business owner seeking ways to future-proof a building and lower the carbon footprint of the property.

HOW DOES A GROUND SOURCE HEAT PUMP WORK?

A ground source heat pump works through a process of absorbing the natural heat from the ground and transferring it into a higher temperature that can be used to provide heat and hot water to a building. It is a low-carbon, energy efficient heating system. The heat pump is installed inside a building and is powered by electricity. The pump is connected to ground collectors – a series of pipes that are underground.

Cold fluid is circulated throughout this pipe network, absorbing the surrounding energy that can be found in rock, soil, lakes, and streams. A compressor within the heat pump then takes the fluid and increases the temperature before passing it through the heat exchanger to heat hot water cylinders, radiators, and other heating systems within the building.

OPEN-LOOP VS CLOSED-LOOP FOR GROUND SOURCE HEAT PUMPS

CLOSED-LOOP SYSTEMS

These tried and true ground source heat pumps have been around for over 50 years. This established technology effectively uses natural heat. These closed-loop systems harness the power of solar radiation. Sun radiation beams down and heats the earth, then stores this heat. These efficient pumps extract this heat via a ground heat exchange loop to tap into these naturally replenishable heat stores. The extracted heat is powerful enough to heat buildings, provide hot water and more.

A mixture of water and antifreeze is circulated around a loop pipe called a ground loop. This will be buried in a garden or lake. The powerful solar heat stored in the ground or lake is absorbed into the fluid and then passes through an intelligent heat exchanger into the heat pump. Because the heat stored in the ground or lake remains at a consistent temperature under the surface, the heat pump can be effectively used throughout the year, including during Winter.

The ground loop length can be tailored to accommodate the size of your home and the heat load you require. Typically, longer loops can draw more heat from the ground. However, these need more space to be buried in. In circumstances where there’s not enough space, a vertical borehole can be drilled as an alternative.

CLOSED-LOOP SYSTEM BENEFITS

  • Depending on which fuel you’re replacing, this energy source could lower your home’s carbon emissions.
  • They may lower your fuel bills. This is particularly true if you currently replace conventional electric heating.
  • You may be eligible for payments through the government’s Renewable Heat Incentive (RHI).
  • With this system, there are no fuel deliveries required.
  • These ground-source heat pumps are more energy efficient than air-source heat pumps.
  • The heat pumps are used to deliver heat at lower temperatures over longer periods, intelligently and efficiently conserving and maintaining heat flow.
  • Requires minimal maintenance.

OPEN-LOOP SYSTEMS

Just like closed-loop systems, these water source heat pumps operate by efficiently extracting thermal from a water source close to the property which requires heating. The thermal energy is collected and converted into heat and hot water. An adequate body of water close by is required for water source heat pumps to function. This makes them ideal for homeowners who have a lake, river, stream or borehole close by.

Water flows through the pump and the heat is extracted by the open-loop system installed and then discharged back to its source. This makes them super efficient — more efficient than closed-loop pumps. However, there are additional regulations to consider from either the Environment Agency for England and Wales or the Scottish Environment Protection Agency (SEPA). You’ll need to gain consent from either of these bodies to install and use one of these systems. This is because these systems actively pull water into the system for operation, and the water needs to be clean, safe and sufficient for the system to draw and filter the water to and fro the main water source.

OPEN-LOOP SYSTEM BENEFITS

  • Provides a reliable supply of water and domestic hot water heating.
  • Environmentally friendly.
  • No need for fuel deliveries.
  • May lower your fuel bills. This is especially true if you currently replace oil or conventional electric heating.
  • In general, these systems are more efficient than closed-loop.
  • You may be eligible for payments through the government’s Renewable Heat Incentive (RHI).
  • Depending on which fuel you’re replacing, this energy source could lower your home’s carbon emissions.

BORE HOLES VS SLINKIES FOR GROUND SOURCE HEAT PUMPS

BORE HOLES

Ground source heat pump boreholes extract heat energy from rock. They’re vertical ground arrays or collectors used to extract heat energy from rock to a ground source heat pump. They effectively save space, minimising any disruption in heat pump installation projects. Typically only 150mm width of garden space is required per borehole. The depths of boreholes generally range from 60m-200m.

They work by collecting solar energy stored in the surface soil that dissipates through rock layers. This provides a stable and sustainable heat source. During installation, a U-shaped straight pipe is inserted into the borehole and connected through a trench to the ground source heat pump. The surrounding space is backfilled with a thermal grout to ensure thermal conductivity from the ground to the borehole pipe.

Ground source heat pump boreholes are generally used for large commercial projects, district heating schemes and even smaller sites where space saving is a priority. They also prove a great solution for when there’s insufficient space for horizontal arrays such as slinky pipes in trenches. One borehole is typically required per property. The ground source heat pump circulates heat transfer fluid through the U-pipe.

Boreholes are more expensive than slinky pipes. This is due to additional preparation and drilling costs. However, boreholes are becoming economically viable through Shared Group Loop Array schemes for multiple residential properties, large commercial projects and any site with heat loads above 100 kW. Reduced mobilisation costs for the drilling rig, on-site scalable efficiency and the degree of diversification applied to save money in the long run.

BORE HOLES BENEFITS

  • Boreholes can prove a great long-term investment
  • Works well for both residential and commercial use
  • They increase property value.
  • Easy maintenance.
  • They save money in the long run.
  • The water supply is uninterruptible.

SLINKIES (SLINKY PIPES)

Slinky pipes, or slinkies, collect heat from surface soil. They do this roughly 1.2m below the ground. The soil continuously gains and replenishes most of its heat from solar energy. From this, they’re able to effectively maintain a consistent temperature of between 8-12°C year-round. Soil was the first heat source used to work with ground source heat pumps, and continues to be a reliable source for heat pumps. This makes Slinkies continuously viable and naturally efficient heating.

Slinkies work by extracting heat through pipeworks from surface soil buried in trenches. This pipework is between fine layers of sand to ensure optimal contact with the ground for maximum heat extraction. In another trench header pipe work connects the slinky to the ground source heat pump by a manifold. Global and water are pumped around the pipework which absorbs energy stored in the ground and effectively transfers thesis energy back to the heat pump. The pipe is able to extract heat from the earth year-round and can last for a lifetime — up to 100 years.

Slinkies are very effective and easy to install. The ground array required is sized appropriately to meet the building’s required heat load. For every 60m of pipe, about 1 kW of energy is typically absorbed from the ground. They’re the most common method of all ground array collectors used for individual property projects.

SLINKIES BENEFITS

  • Only a small amount of digging is required.
  • Quick and relatively painless installation.
  • Requires less land than some other methods.
  • Saves on initial installation costs.
  • Works well for individual property projects.

GROUND SOURCE HEAT PUMP EMISSIONS

Ground source heat pumps boast high efficiency due to the fact that they emit no emissions. As a genuine, effective, low-carbon alternative to fossil fuel heating systems there are few better options open to property owners. Poor air quality accounts for many deaths each year and with the help of a low-carbon heating system you could reduce the emissions linked to your property.

A ground source heat pump does not create particulates, Sulphur Oxide (SOx) or Nitrogen Oxide (NOx). On top of that, the greater the contribution of solar and wind power systems to the electrical grid, the lower the carbon content of electricity. This should mean that over time, ground source heat pumps become even less carbon intensive.

HEAT PUMPS FAQ

Clade Engineering is able to provide heat pumps as either air, ground, or water source. The most suitable type of heat pump depends on several factors related to your property. Generally, air source heat pumps are the most popular because they have the fewest requirements to install. Any type of heat pump can provide hot water and heating to your building.

Heat pumps using CO2 refrigerant as the heat source are friendly to the environment because the CO2 they use stays contained within the appliance and does not get released into the atmosphere. Furthermore, the CO2 we use in our heat pumps has the lowest global warming potential (GWP) of 1 compared to 1000’s for other refrigerants which will all significantly reduce the carbon footprint of your building.

Clade are the industry leaders in heat pump technology.
