Use current site, supplier and regulatory inputs to compare delivered heat cost, emissions, capacity and operational risk.
Use the same system boundary for every option. Compare useful heat delivered to the process, not the purchased energy price alone.
| Route | Cost inputs | Emissions inputs | Engineering checks |
|---|---|---|---|
| Natural gas | Fuel price, boiler efficiency, carbon cost | Metered fuel use and applicable emissions factor | Combustion, supply and carbon-price exposure |
| Biomass | Delivered fuel, conversion, storage and handling | Fuel classification and sustainability evidence | Air emissions, fuel quality and supply security |
| Heat pump | Electricity price and coefficient of performance | Electricity factor for the reporting method | Source temperature, sink temperature, electrical capacity |
| Direct electric | Electricity price and conversion efficiency | Electricity factor for the reporting method | Grid connection, demand and process control |
| Hydrogen | Delivered hydrogen and conversion efficiency | Production-route evidence and reporting rules | Availability, storage, burners and safety case |
Prices and emissions factors are deliberately not pre-filled. Use current contracts, supplier evidence and the factors required by the applicable reporting scheme.
Use the heat-loss calculators and Heat Explorer to assess exposed equipment before sizing a replacement heat source.
Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.
Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.
