Sustainable Energy Innovation
Harvest the heat.
Cut the carbon.
Unlock 20% Energy Savings — Without Replacing a Single Boiler
The Challenge We Solve
Rising energy costs and carbon emissions demand practical, affordable solutions — not costly infrastructure overhauls.
Global: Carbon Emissions
Fossil fuel combustion for heating and industry drives greenhouse gas emissions. Despite international efforts, carbon output continues to rise — and many green alternatives are too expensive for widespread adoption.
UK: Cost of Living Crisis
Volatile energy markets and rising gas prices are squeezing businesses and public sectors. Alternative technologies require costly installations and system replacements that many simply cannot afford.
Our Solution
Transform waste heat into valuable energy with plug-and-play technology for both new build and retrofit markets
How It Works
Our Air to Flue Gas Heat Recovery Device (AFHR), developed with Robert Gordon University, captures waste heat from existing boiler flue gases and redistributes it as warm air — reducing gas consumption by up to 20%.
