Econergy is a technical review of an existing heating system, not a subsidy scheme and not a sales form. It starts with how much energy the building uses today, where the loss occurs, and which measure is concrete enough to compare with investment cost.
What the review actually measures
The original Solaronics Econergy page frames the issue in terms industrial buyers already see in invoices: buildings represent a large share of final energy consumption, and heating is one of the largest loads. For a company, the more useful local question is this: how much gas, electricity or LPG does your building consume per operating hour, and how much of that energy never reaches the occupied zone.
The review therefore does not measure only the boiler or burner. It measures the building as a system: hall height, envelope insulation, door operation, work zones, temperature settings, equipment age, fan layout, control condition and the latest combustion service records. If any of these inputs is missing, the savings calculation is too soft for an investment decision.
| Input | Why it is needed | Typical source |
|---|---|---|
| Annual fuel consumption | baseline for comparison | invoices, meter, energy register |
| Operating hours | separates continuous production from seasonal use | shift schedule, BMS, service log |
| Hall height and floor area | defines volume and stratification | drawings, site visit |
| Doors and openings | show logistics losses | door list, opening cycles |
| Equipment age and type | shows whether the issue is efficiency, controls or wrong technology | nameplates, manuals, service record |
Three levels of measures
The first level is settings. This includes heating curves, schedules, zoning, thermostats and start-up sequence. In a building where the equipment type is correct but the control strategy is weak, this is the first path to check. The measure does not always require a new appliance, but it does require an initial record and a later comparison.
The second level is system correction. This means air curtains at doors, destratification for warm-air heating, sensor relocation, burner service, zone balancing or replacement of incorrect accessories. This level is relevant when the basic technology suits the building, but losses are created at the edges of the system.
The third level is replacement or a combination of technologies. A high hall with long operating hours may need radiant plaques or radiant tubes instead of warm-air heating. A well-insulated lower building can remain with gas unit heaters if the condensing version and controls produce the better calculation.
What the review output looks like
A useful Econergy output is not a long description of the current state. It is a decision table that can be used for internal investment approval. Each measure needs an estimated effect, implementation dependency, operational constraint and the metric to check after completion.
| Measure | Effect on consumption | Implementation dependency | Post-check |
|---|---|---|---|
| schedule correction | low to medium | access to controls | weekly consumption comparison |
| hall zoning | medium | separation of work areas | temperature by zone |
| air curtain at doors | medium to high in logistics | opening size, door cycle | temperature drop during opening |
| system replacement | high if the technology is wrong | design, gas, flue, mounting | seasonal consumption per operating hour |
When a review is not enough
If the building has no basic consumption data, the first step is measurement. If the equipment is faulty, diagnostics come first. If the building is new, Econergy is not a substitute for design; the more useful route is technical system selection by height, insulation and operating pattern.
A good question before ordering the review is simple: can you show twelve months of consumption and describe when the building actually operates. If yes, the review can be done without guessing. If not, first establish a record or order an initial measurement.
