Preheating burner air with flue gas (recuperator/regenerator) returns heat directly into combustion — standard on furnaces, underused on mid-size boilers.

Every 20 °C of air preheat ≈ 1% fuel. On furnaces, regenerative burners reach 50%+ of flue-heat recovery. Watch NOx — preheat raises flame temperature; modern low-NOx burners co-engineer the two.
Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes Inzonex Modular Insulation — snap-fastened modules engineered per temperature tier, not generic off-the-shelf jackets:
Every tonne you stop emitting is a tonne you don't have to report: cutting heat loss is a measurable, auditable Scope 1 reduction that flows straight into EU ETS, CBAM and your ESG / CSRD disclosures — not an offset, an actual emission cut.
