5 Things to Consider When Choosing Between Ground Source Heat Pumps and Air Source Heat Pumps
For sustainable and energy efficient heating, cooling, or any temperature control, pumps are the best option. You need to assess your property’s specific requirements, budget, and long term plans before deciding between a ground source heat pump and an air source system. Below are cost-effective tips to aid with the decision making process alongside your air source heat pump installers.
1. Efficiency and Performance
Ground source heat pumps are more efficient than air source systems because the ground maintains a stable temperature year-round. This makes them ideal for colder climates where the air temperature varies greatly. Air source heat pumps are good for moderate climates but may need more electricity in the colder months to maintain efficiency. Tell your installers about your property’s climate and they will assist you in making that decision.
2. Installation Requirements
Ground source heat pumps need more outdoor space for excavation and underground loops, so are better suited for properties with big gardens or open land. Air source heat pumps are easier to install, just an outdoor unit and minimal space. A professional air source heat pump installer can get these systems installed very quickly so are a good choice for properties with restricted outdoor space.
3. Cost
Installing ground source heat pumps are more expensive due to the excavation and complicated setup required, however, they are more efficient with energy saving in the long term and greatly help with reducing expenses. While air source heat pumps are less expensive, they do tend to have slightly higher running costs in colder climates. Both options may qualify for government subsidy such as the Boiler Upgrade Scheme that can help cover some of the initial costs.
4. Longevity and Maintenance
With ground source heat pumps, the underground components can last over fifty years, and the indoor units up to twenty-five years which is much longer than air source systems. Overall, air source systems have about a fifteen to twenty year lifespan but require a lot less servicing and maintenance which simpler systems tend to provide. Both systems will require qualified installers regularly, but once done will make the systems operate efficiently for the rest of their lifecycle.
5. Sustainability
Both ground and air source heat pumps assist in using renewable energy sources that reduce your dependency on fossil fuels and the emission of carbon. While ground source systems tend to be more efficient in reducing eco damage, air sources are a friendlier option for retrofitting older systems for homes and replacing fossil fuel heating systems.
Discuss with your installers and provide them with your property details, and they can assist you with the decision-making process.
