What Should You Consider When Buying Air Source Heat Pumps?
When considering energy-efficient heating solutions, one popular option is the air source heat pump (ASHP). If you are in the market to purchase a new heat pump, there are several important factors to consider to ensure you make the best choice for your home.

Understanding Air Source Heat Pumps
An air source heat pump works by extracting heat from the outside air, even in cold temperatures, and transferring it into your home. This system is not only energy-efficient but can also significantly reduce your heating bills. According to the Energy Saving Trust, heat pumps can lead to savings of around £1,000 per year on energy costs compared to traditional heating systems. However, there are various aspects to assess before making a purchase.
Key Considerations When Buying Air Source Heat Pumps
1. Size and Capacity
One of the most critical factors to consider is the size and capacity of the air source heat pump. An undersized unit may struggle to heat your home efficiently, while an oversized unit can lead to higher energy bills and reduced lifespan. To determine the appropriate size, consult a qualified technician who can conduct a heat loss assessment of your property. The UK government recommends that the capacity be calculated in kilowatts (kW), based on your home’s specific heating demands.
2. Efficiency Ratings
Look for the efficiency ratings of the heat pumps you are considering. The seasonal coefficient of performance (SCOP) is a critical figure that indicates the unit's efficiency over an entire season. A higher SCOP means better energy efficiency. According to the Carbon Trust, heat pumps typically have SCOPs ranging from 3 to 4, meaning they can produce three to four units of heat for every unit of electricity consumed.
3. Installation Costs and Grants
The initial installation cost can vary significantly, ranging from £7,000 to £13,000 in the UK, depending on the complexity of the installation and the specific product. However, there are various grants and incentives available, such as the Renewable Heat Incentive (RHI), which can help offset these costs. Always check for local subsidies that encourage the adoption of heat pumps.
4. Noise Levels
Noise levels can also influence your decision. Modern air source heat pumps are designed to operate quietly, but some units can be louder than others. The noise level is typically measured in decibels (dB). Look for models that operate at 50 dB or less for minimal disturbance.
5. Air Source Heat Pump Buffer Tank
Integrating an air source heat pump buffer tank into your system can enhance efficiency and performance. A buffer tank helps to stabilize the heating system and allows for smoother operation by reducing short-cycling of the heat pump. This can improve both the lifespan of the unit and the comfort level within your home. When purchasing a heat pump, consider whether a buffer tank is necessary for your installation.
6. Manufacturer Reputation and Warranty
Choosing a reliable manufacturer is crucial. Look for brands that offer strong warranties, typically ranging from 5 to 10 years, which can provide peace of mind. Research user reviews and ratings to assess the quality of the units and after-sales support.
7. Compatibility with Existing Systems

If you are replacing an old heating system, consider how the new air source heat pump will integrate with your existing setup. Some heat pumps can work well with underfloor heating, while others may be more suited to radiators.
8. Climate Considerations
The effectiveness of air source heat pumps can vary depending on the climate of your region. While these systems can work efficiently even in cold temperatures, their performance may decrease in extremely cold winters. It's vital to evaluate local climate conditions and possibly consider a hybrid system that combines solar, biomass, or traditional heat sources for optimal results.
Conclusion
Purchasing an air source heat pump is a significant investment that requires careful consideration of various factors such as size, efficiency, installation costs, and compatibility with existing heating systems. By focusing on the essential aspects highlighted in this guide, including the importance of considering an air source heat pump buffer tank, you can make a well-informed decision that meets your heating needs while maximizing energy efficiency. Make sure to conduct thorough research and consult professionals to find the most suitable heat pump for your home.
