If you live in an older home in Edinburgh, the Lothians, Fife, or the Scottish Borders, you might be wondering: Are air source heat pumps (ASHPs) suitable for old houses? After all, traditional heating systems have been the norm for decades, and older buildings often have unique characteristics that can complicate upgrades.
At Latent Heat Edinburgh, we understand these concerns and are here to help you navigate your options. Here’s everything you need to know about heat pumps and older properties.
What Makes Old Houses Different?
Older homes, especially those built before the 1950s, often have:
- Solid walls rather than cavity walls
- Less insulation compared to modern builds
- Older window and door designs that may be draughty
- Heating systems designed for high-temperature radiators or open fires
These factors can affect how a heat pump works — but it doesn’t rule them out.
Can Heat Pumps Work in Old Houses?
Yes, but with some important considerations:
1. Improving Insulation is Key
Heat pumps work most efficiently in well-insulated buildings. If your home lacks insulation, upgrading lofts, walls, floors, and windows is a smart first step. This reduces heat loss and helps the heat pump maintain a comfortable temperature without overworking.
2. Low-Temperature Heating Systems Are Better
Heat pumps deliver heat at lower temperatures than gas boilers. This means your old radiators might need to be upgraded to larger radiators designed for low-temperature systems. If you have underfloor heating this is a great match for an air source heat pump.
3. Hot Water Storage May Be Required
Older homes often rely on combi boilers with no tank. Heat pumps usually need a hot water cylinder or tank to store heated water efficiently.
4. Space for the Heat Pump Unit
Air source heat pumps require an outdoor unit with good airflow, ideally next to the back or any side wall of the property.
Benefits of Heat Pumps in Older Homes
Heat pumps are a fantastic choice:
- Lower carbon footprint: Replacing oil or coal heating drastically cuts emissions.
- Stable, efficient heat: Once installed and optimised, heat pumps provide comfortable warmth year-round.
- Reduced running costs: Wheny when paired with insulation improvements.
- Eligibility for grants: You may qualify for Scottish Government or Home Energy Scotland funding to help with upgrade costs.
