Vaillant has partnered with English Heritage to support the charity’s Sustainable Conservation goals and help modernise the heating systems in a selection of its much‑loved holiday cottages.
Watch below as we chat with English Heritage about the evolution of heating in historic buildings and share more about how air source heat pumps are being successfully integrated into their unique holiday cottages.

Vaillant supports English Heritage’s journey to net zero with heat pump upgrades
Vaillant supply air source heat pumps to eight English Heritage holiday cottages, helping to reduce carbon emissions across their sites.

English Heritage cares for more than 400 historic sites across England, and as part of its long‑term conservation strategy, the charity has committed to reaching net zero carbon emissions by 2040.
To help them move towards this ambition, we’re installing eight of our aroTHERM plus air source heat pumps across their holiday cottage collection—replacing older oil systems and gas boilers with cleaner, low‑carbon technology.

Two of these installations are already complete. One is at Coastguards Cottage, on the island of Lindisfarne, also known as the Holy Island, a three‑bedroom property just a short walk from Lindisfarne Priory, where the system has proven itself in snow and exposed coastal weather.
The other is at Fort House in St Mawes, a charming cliff‑top cottage next to St Mawes Castle, where the heat pump performs brilliantly despite its rugged, windswept location.
A further six English Heritage properties—including Peacock Cottage at Kirby Hall, Refectory Cottage at Rievaulx Abbey, and Custodian House at Pendennis Castle — are scheduled for upgrades as part of this ongoing programme.
This project shows just how well modern heat pump technology can work in older buildings, even in challenging environments. It helps break down common misconceptions by proving that these systems can be retrofitted smoothly, deliver reliable warmth all year round, and significantly reduce carbon emissions—all while keeping holiday guests comfortable.
