One way in which we do this is through partnering with leaders in the renewable energy sector, to offer services which will benefit both your project and the planet. An example of this in action is the use of Ground Source Heat Pumps (GSHPs) as a means of providing heating to a project. Read on to find out more about how they work and why they could be beneficial for you.
What are they?
Ground source heat pumps (GSHPs) use pipes that are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home.
How do they work?
It’s actually quite simple. A GSHP circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop, which is buried in your garden. The heat from the ground is then absorbed into the fluid and then passes through a heat exchanger into the heat pump.
The ground stays at a reasonably constant temperature under the surface, so the heat pump can be used throughout the year.
It’s important to note that the size of your home and amount of heat you need will affect the length of the ground loop required. Whilst longer loops can draw more heat from the ground, they need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.
What are the benefits?
GSHPs have low running costs because they exploit the natural characteristic of the ground to act as an efficient store of thermal energy.
The high thermal energy storage capacity of the ground allows GSHPs to be used efficiently at all hours of day and night.
GSHPs do not suffer irregularities that affect other renewable energy systems. The thermal energy storage capacity of the ground can compensate for the intermittent supply of energy from other renewable sources.
Investment in ground source energy lasts much longer than other investments in renewable energy. The ground works installed for ground source systems, can be expected to last for over 50 years. The ground source heat pumps themselves are very reliable pieces of equipment with a long life.
GSHPs are one of the most economic routes to providing on-site renewable heating, reducing emissions of greenhouse gases and meeting the government's binding targets on renewable energy.
GSHP systems are highly valued - they are silent, free from polluting chemicals, reliable and invisible. They are welcomed by planning authorities and architects. They produce no carbon emissions on site, and none anywhere if they’re powered by renewable electricity.
GSHP systems, uniquely amongst renewable energy technologies, offer the opportunity to recycle heat energy. Heat energy can be captured when it is freely available in the summer, stored in the ground over the autumn, and released to heat buildings in winter.
Unlike any other form of renewable technology, the power of a heat pump can be reversed in the summer season to provide cooling. In the case of an air source heat pump, heat which is taken out of a building in the summer is merely "wasted" to the atmosphere. This makes it a very expensive option. The renewable cooling alternative uses a ground source heat pump to heat exchange with cold ground: the advantage of which is that it is much more efficient than heat exchanging with hot air.
The UK Government offers a financial award to people who choose to use renewable energy such as GHSPs to heat their homes. This is known as the Renewable Heat Incentive. The government scheme could give you quarterly payments for seven years if you install, or have already installed, renewable technology to heat your home.
How do we use this technique?
MCD Construction works closely with ground source heat pump specialists who are widely acknowledged as the leading geothermal drillers within the UK. These businesses have a particular focus on geothermal borehole drilling, including design to installation services.
As a company, we provide complete solutions. This means that we will design, drill and install all heat pumps for our customers. Not only does this provide a singular point to get all this work done at once, but it also means that our clients can be reassured that all the parts work together efficiently and effectively throughout the entirety of the installation process.
In addition to this, we also offer solar panel packages, which allow the client to become completely carbon neutral and power the heat pumps through solar energy.
