FAQs
What is an air source heat pump?
An air source heat pump is a system that extracts heat from the outside air and transfers it indoors to heat your home. It can also work in reverse to cool your home in warmer months. ASHPs are an energy-efficient, eco-friendly alternative to traditional heating systems.
How do air source heat pumps work in cold weather?
Air source heat pumps can operate in temperatures as low as -15 to -25°C (5 to -13°F), depending on the model. Advanced technology allows them to extract heat even from cold air. However, efficiency may decrease at very low temperatures, so a backup heating source may be recommended in extremely cold climates.
Are air source heat pumps energy efficient?
Yes! ASHPs can be very energy-efficient. For every unit of electricity used, they can produce 2-4 units of heat, making them 200-400% efficient. This can lead to significant energy savings, especially when replacing electric or oil-based heating systems.
Can an air source heat pump work with existing heating systems?
In many cases, yes. ASHPs can be integrated with existing heating systems like radiators or underfloor heating. However, they work best with low-temperature heating systems, as they are designed to heat water to lower temperatures than traditional boilers.
How much can I save on my energy bills with an air source heat pump?
Potential savings depend on factors like your current heating system, insulation levels, and local energy costs. Generally, switching from oil, electric, or LPG heating to an ASHP can save you between 20-50% on heating bills.
Are air source heat pumps noisy?
Modern ASHPs are designed to be quiet. While the outdoor unit does make some noise, it’s usually comparable to a quiet fan or air conditioner. Placement and distance from living spaces can further reduce any noise impact.

Do air source heat pumps require much maintenance?
Air source heat pumps require minimal maintenance. It’s recommended to have them professionally serviced once a year. Routine homeowner tasks include keeping the outdoor unit clear of leaves, snow, and debris.
Can air source heat pumps provide hot water as well?
Yes, some ASHP models are designed to heat both space and water. However, heating water to high temperatures may reduce efficiency. A hot water storage tank is usually required for these systems.
Are there any government incentives for installing an air source heat pump?
In many countries, yes. Programs like the UK’s Boiler Upgrade Scheme or the US’s federal tax credits provide financial incentives to reduce upfront installation costs for renewable heating systems like ASHPs. Check local regulations for availability and requirements.
