Compare the system boundary, evidence and constraints. The page does not assign a universal winner.
| Check | Solar thermal process heat | Industrial heat pumps |
|---|---|---|
| System change | Use solar collectors to supply or preheat a suitable thermal duty. | Raise the temperature of a lower-grade heat source so that it can supply a useful process duty. |
| Evidence required | Hourly demand, temperature, solar resource, collector performance, storage, land or roof constraints and backup system. | Source and sink profiles, temperatures, simultaneous hours, refrigerant, seasonal performance, electricity supply and backup duty. |
| Principal constraint | Annual resource and demand coincidence determine useful output; nameplate area alone is insufficient. | A nominal coefficient of performance does not replace a design-point and annual operating assessment. |

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.
