What are the installation options for a ground source heat pump system?
Depending on the scope of your outdoor space, a ground source heat pump system can be installed vertically using boreholes or horizontally using trenches.
Does a ground source heat pump system require a lot of space?
The size of your outdoor space is a consideration when making plans for a ground source heat pump.
Trenches are the most cost-effective way of installing a ground source heat pump.
Pipes need to be located under the frost line at around 1.2m deep and trenches are roughly 1m wide. For context, an average 4-bedroom house may need 350 linear metres of trenching to provide enough heat transfer for the property’s heating and hot water demand.
If space is at a premium, boreholes tend to be a better option. This involves drilling down vertically (approx max depth 150m/hole before starting another) creating a 6-8inch hole. Each borehole is spaced apart and covered to leave no trace.
The internal plant equipment (GSHP, hot water cylinder and buffer tank) takes up more room than a traditional boiler system so consideration will need to be given as to where to site the heat pump kit.
What is the difference between a ground source and air source heat pump?
Ground source heat pumps (GSHPs) absorb heat from the ground outside your home, whereas air source heat pumps (ASHPs) absorb heat from the air.
ASHP’s can be simpler and cheaper to install than GSHPs, but they are often less efficient due to the temperature variations of the outdoor environment.
Can a ground source heat pump help to lower my carbon footprint?
Without a doubt. Ground source heat pumps forego the use of fossil fuels, utilising only small amounts of electricity in order to operate.
This makes them the most environmentally friendly option available on the market.
What are the financial benefits of a ground source pump system?
After the initial installation investment, the long-term savings on energy bills will nearly always outweigh the setup cost of a heat pump system.
What’s more, ground source heat pumps have been proven to add significant value to a property thanks to a growing demand for renewable energy from potential buyers.
Do ground source heat pumps provide heating and cooling?
Cooling using heat pumps is definitely an option but for most people, it’s a false economy.
In most cases, if you’re looking for a cooling system we recommend standard air conditioning as a straightforward way to cool a space
Does a ground source heat pump enhance air quality?
A heat pump system heats your home without burning anything, eliminating the risk of carbon monoxide filling your indoor air.
Unlike air conditioning systems, heat pumps don’t dry out the air, so there’s a better balance of humidity and comfort in your living space.
Heat pumps also tend to “hold” a property at the desired temperature rather than rely on spikes or bursts of heating. This ensures your home and its contents are protected from constant changes in temperature
Are ground source heat pump systems easy to maintain?
Heat pump systems are a lot easier to maintain than combustion heating systems.
A typical ground source heating system requires a professional service every year. Such regular maintenance is enough to make the system operate for 25 years or more.
Are ground source heat pumps noisy?
A ground source heat pump is no noisier than a modern boiler. When an older boiler starts up or the external flue goes, both these sounds are louder than a ground source heat pump.
Are there any grants to help with the cost of installing a heat pump system?
The Boiler Upgrade Scheme (BUS) is a government-funded subsidy that provides an upfront grant of £7,500 to support the installation of heat pumps. This is available to all homeowners.
