Modernising historic homes historically meant compromising their character.
Listed building consent and conservation area restrictions rightly protect our heritage architecture. This makes installing highly visible and noisy air source heat pumps virtually impossible on many Grade I, Grade II*, and Grade II properties.
Deep borehole ground source systems present their own risks, requiring heavy excavation machinery that threatens archaeological layers and historic gardens.
The Teratherm Solution
Surface Thermal answers the conservation challenge. We turn existing hardstanding—courtyards, estate driveways, and patios—into massive energy collectors at just 50mm depth.
- No alterations to historic facades
- No deep drilling threatening archaeology
- Zero acoustic impact on tranquil grounds
Heritage-First Engineering
Designed to satisfy the strict requirements of English Heritage and local conservation officers.
Zero Visual Impact
Conservation officers often reject ASHPs due to bulky fan units. Teratherm is entirely invisible, preserving your property's historic facade.
Protects Archaeology
No deep boreholes required. We operate at just 50mm depth within the makeup of standard driveways and courtyards.
Completely Silent
No mechanical outdoor fans generating noise. Keep tranquil historic estates and courtyards perfectly quiet.
