Heat Pumps Explained Simply: How They Work in Scotland
Quick Answer
Heat pumps extract warmth from outside air (air source) or ground (ground source) and concentrate it to heat your home. They work like a refrigerator in reverse. Modern air source heat pumps operate efficiently down to -15°C, making them suitable for Scottish winters. They typically deliver 3-4 units of heat for every unit of electricity used.

Frequently Asked Questions
Yes. Modern air source heat pumps work efficiently down to -15°C or lower. They've been used successfully in Scandinavia for decades.
Heat pumps typically achieve 300-400% efficiency (COP of 3-4). This means 3-4kWh of heat for every 1kWh of electricity.
Modern units are quiet - about 40-50 decibels at 1 metre (similar to a refrigerator). Planning guidelines ensure noise isn't problematic.
Air source units need about 1m² outside. Ground source requires garden space for loops or a borehole.
Often yes. Heat pumps work best with larger radiators or underfloor heating due to lower flow temperatures.
