Transforming Waste Heat into Sustainable Energy Savings.

Our advanced heat recovery technology captures wasted energy from boiler flue gases and converts it into usable heat, helping organisations reduce energy waste, carbon emissions, and heating expenses.

The Problem

Every day, buildings waste a significant amount of valuable heat energy through boiler flue gases and heating systems. This lost energy increases fuel consumption, raises heating costs, and contributes to unnecessary carbon emissions.

Solution

Transform waste heat into valuable energy with plug-and-play technology for both new build and retrofit markets

Lower Gas Consumption

Developed with Robert Gordon University, AFHR can reduce gas consumption by up to 20%, supporting lower costs and carbon reduction.

The Challenge We Solve

Rising energy costs and carbon emissions demand practical, affordable solutions — not costly infrastructure overhauls.

Carbon emissions and industrial energy usage

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.

Cost of living and gas price pressures

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.
