Yes, often you can. An older stone-built Scottish home is not automatically ruled out for a heat pump.
What matters is how the house actually performs, not just that it is old. Some stone properties have already had insulation upgrades, draught-proofing, and sensible radiator improvements, and those homes can be very good candidates. Others lose heat quickly and need work to the fabric or the emitters before a heat pump will be comfortable and efficient.
For older homes we pay particular attention to:
- the real room-by-room heat loss rather than a rule-of-thumb estimate
- where draughts and cold bridging are likely to be affecting comfort
- whether the existing radiators are big enough at lower flow temperatures
- whether there is practical space for the cylinder and indoor kit
- outdoor-unit siting and any planning constraints tied to the property
If the house is not ready today, we will tell you what would need to change first. That might be a handful of radiator upgrades, some fabric work, or in some cases choosing a boiler for now and revisiting a heat pump later. The honest answer is still far better than forcing the wrong system into the property.
