A remarkable energy upgrade for a historic Midlothian home.
This beautiful 19th‑century sandstone lodge has come a long way. Once heated only by a coal fire, it now runs on 100% renewable energy thanks to a 30kW ETA SH30 log boiler, expertly installed by Border Eco Systems.
After looking into heat pumps and other low‑carbon technologies, the homeowners chose ETA for its reliability, independence, and future‑ready design, a system that gives them full control while respecting the character of their rural home.
With a 2,000‑litre thermal store at the heart of the setup, the boiler now powers underfloor heating, radiators, and hot water.
The result?
A warm, comfortable home that’s efficient today and sustainable for decades to come.
This project shows just how achievable modern, low‑carbon heating can be for rural and historic properties and how transformative the right system can feel.
