A realistic guide for traditionally built properties in Devon and Cornwall.
Many homeowners with older properties wonder whether a heat pump is a realistic option for them. While heat pumps can work well in traditionally built homes, success depends heavily on the condition of the property and how the system is designed.
Here’s what actually matters when considering a heat pump in an older home.
Older homes often have poorer insulation than modern properties. This means they lose heat more quickly, which can lead to higher running costs if insulation improvements are not made alongside the heat pump.
Traditional radiator systems in older homes are often designed for higher water temperatures. Heat pumps work best at lower temperatures, so radiators may need upgrading or additional emitters may be required.
Most heat pump installations require a new, larger hot water cylinder. Finding suitable space for this can sometimes be a challenge in older properties.
Older homes are often draughty. Improving airtightness through simple measures like draught proofing can make a noticeable difference to how efficiently a heat pump performs.
Heat pumps can perform well in older homes when the following conditions are met:
Focus on loft insulation, draught proofing, and any accessible wall or floor insulation. This usually gives the best return on investment.
Where practical, underfloor heating works very well with heat pumps because it operates at lower temperatures. This is especially useful on ground floors.
Choose an installer who has experience with retrofit projects in older properties, not just new builds.
Most heat pump systems need a larger hot water cylinder. Plan for this early in the project.
