Caerlee, Innerleithen property and heating guide
Caerlee climbs the north side of Innerleithen above the old mill, a mix of Victorian mill-workers' terraces, mid-century detached homes and newer builds at the top of the rise. Mains gas covers the lower terraces, but the higher ground around Caerlee Mill Brae often runs on LPG or oil. The Tweed valley microclimate gives sharp overnight frosts in winter, so condensate detailing matters as much as the boiler itself.
Mill-workers' terraces have small kitchens — wall-hung combis usually the only sensible site.
Combi swaps, LPG upgrades and frost-resilient condensate work across Innerleithen's mixed-fuel Caerlee hillside.

Before you book: local practical answers
Why does my Caerlee boiler shut down on cold mornings?+
Frozen condensate — almost universal on exposed external runs in EH44 6. We fix it permanently with 32mm insulated pipe or internal routing.
Is there gas at the top of Caerlee Mill Brae?+
It depends on the exact plot — we check the LPS map and confirm with SGN before quoting. LPG is the common alternative if not.
What makes a visit to Caerlee different from a generic area booking?+
Mill-workers' terraces have small kitchens — wall-hung combis usually the only sensible site. That local constraint is recorded before we recommend equipment, access arrangements or a likely project sequence.
