Legacy Meets Innovation: Sustainable Heating for a Historic Scottish Estate

The Property

Penninghame Estate, with roots tracing back to the early 1700s, was once the seat of the Earl of Galloway and spanned a vast 10,000 acres with over 40 tenanted farms. Today, the estate stands as a symbol of heritage and continuity and now, sustainability.

The Initial Requirements

The existing NIBE Ground Source Heat Pump system, installed nearly 20 years ago, were reaching the end of their lifespan. The estate needed:

• A reliable, high-performance replacement

• Improved energy efficiency

• Seamless integration into a historic property

• Long-term reliability backed by trusted support

Having experienced excellent long-term performance and strong support from NIBE, the estate owners were confident in choosing the NIBE brand again for the upgrade.



This solution not only met the estate’s heating needs but future-proofed it with advanced technology that aligns with modern sustainability goals.
