# Electric water, space and soil heating apparatus and cooking appliances

## 1. Scope and Applicability

This candidate covers factory manufacture of finished electric instantaneous and storage water heaters, immersion heaters, space and soil heating apparatus, ovens, cookers, cooking plates, boiling rings, grillers and roasters. Declare the actual supplied configuration and principal function. Resistance, ceramic PTC, induction and other electrically produced principal heating/cooking mechanisms remain eligible when supported by product evidence; no nickel-chromium or storage-water-heater-only default applies. This is an equipment production reference, not a heat, cooked-food or lifetime service reference.

CPC 44817 is under the domestic-electric-appliance parent. The original gives the full title without a detailed leaf note. Commercial/industrial adaptations, microwave or other electric cooking mechanisms, heat-pump water heaters, and solar/indirect hybrids require item-specific classification and principal-function review; they are neither automatically assigned to 44817 nor rejected because their reference UUID is unresolved. A storage tank with electric backup may principally be an indirect/solar product. A heat pump is not a resistance heater plus an unexplained omission of compressor/refrigerant. Record unresolved classification explicitly and collect the complete actual architecture before choosing guidance.

Purely non-electric cooking/heating apparatus, separately sold parts, supplied heat, installation civil works, crop production, customer cooking and later maintenance are separate outputs or stages. Their absence from this factory reference does not waive upstream burdens for actual purchased modules.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | M = accepted net mass of one complete machine of the same configuration in kg; collect using cp_mass. |
| physical_species | physical material and species records | Mass | kg | Each material/species balance term uses its own composition, assay and wet/dry basis. Gross steel, solder or sludge mass is not contained Fe, Cu, Ni or solvent mass. Electricity and transport are outside this material-assay rule. |
| water_basis | water-bearing physical records | Mass | kg | Convert each measured water volume using its own temperature-dependent measured or documented density; retain input moisture, opening/closing stocks, evaporation, discharge and reaction water. Paired internal return transfers cancel once. |
| utility_basis | energy records | Energy | MJ | Preserve meter units and conversion evidence, voltage, geography and supplier interface. Heat supply and return each use their own mass and specific enthalpy on one datum; subtract returns once only from a gross supply meter, never again from already-net heat. |
| emission_species | direct elementary emissions | Mass | kg | Species, compartment and control outlet must match. NOx expressed as NO2-equivalent requires speciation or a matching reviewed NOx flow, not relabelling all as measured NO2. Fuel carbon alone cannot establish CO or NOx. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Actual received materials, complete purchased modules and supplied utilities at their documented interfaces |
| starting_condition_role | Foreground factory production with linked upstream supply; not burden-free gate inputs |
| product_classification_scope | Full named electric apparatus with actual principal-function classification review for unusual products |
| recursive_input_rule | A same-category bought apparatus/module is one upstream input with supplier identity; do not recursively invent internal manufacture or add its embodied constituents again |
| upstream_dataset_requirement | Match actual grade, formulation, module completeness, geography, time, electricity voltage and waste-treatment interface; supplier disaggregation replaces rather than supplements a complete module dataset |
| disclosure | Declare missing supplier data, classification/UUID gaps, all conditional operations, factory fills, test loads and downstream stages |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| boundary_factory | foreground | Include actual fabrication, coating/enamelling, polymer processing, heater or electronics manufacture, assembly, accepted and rejected test/rework loads, packaging and attributable services. Retain external upstream supply and waste treatment. | rangemaster-quick-guide |
| boundary_use | factory versus use | Include factory electrical/pressure/cooking test energy and media; exclude customer heat generation, food/crop inputs and service life from this reference. Factory water drains are measured, not retained as sold heat or drinking water. |  |
| boundary_uncertain | hybrid and unusual architectures | Hold item-specific selection pending principal-function review; do not force omission, generic-reference substitution or a universal industrial classification. If confirmed in scope, add actual compressor, refrigerant and heat exchanger or other distinct modules as atomic exchanges. | unsd-cpc3-2025; stiebel-storage-hybrid; dimplex-heating-2026 |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| fabrication | Metal bodies, vessels and cooking cavities | conditional | own cutting, forming, welding or finishing | foreground production | per 1 kg reference flow |
| heater | Heating element and thermal-storage manufacture | conditional | own heater, cable or thermal-storage fabrication | foreground production | per 1 kg reference flow |
| polymer | Polymer moulding and insulation foaming | conditional | own moulding or reactive foam production | foreground production | per 1 kg reference flow |
| electronics | Induction coil and control assembly | conditional | own winding or board assembly | foreground production | per 1 kg reference flow |
| assembly | Configured appliance assembly | required | each declared finished configuration | foreground production | per 1 kg reference flow |
| test | Factory acceptance and rework | required | actual applicable safety and function tests | foreground production | per 1 kg reference flow |
| dispatch | Packaging and factory dispatch | required | factory-ready dispatch | foreground production | per 1 kg reference flow |
| services | Residual shared factory services | conditional | measured unassigned residual after process meters | foreground production | per 1 kg reference flow |

### Architecture and make/buy decisions

| Branch | Actual process evidence and make/buy rule | source_ids |
| --- | --- | --- |
| Instantaneous / immersion | Bare-wire insulating block or tube/spiral/filler are distinct. Bought finished heater replaces its own wire/tube/filler production. Declare seals, pressure parts and sensors. | stiebel-instantaneous |
| Storage water | Vessel, corrosion protection/anode, insulation, controls and electric module; own enamel/foam route differs from buying finished insulated vessel. Polyol, isocyanate, blowing agent and releases require actual recipe if foaming. | stiebel-storage-hybrid |
| Space heating | Radiant/convector, fan/PTC, thermal-storage cells or factory-filled liquid radiators are distinct. Buy full fan/thermal module once or model actual own manufacture. Oil-free design has no assumed oil. | dimplex-heating-2026; tdk-ptc-2026 |
| Soil heating | Cable conductor/heater, insulation/jacket, cold ends, seals, connector and thermostat as supplied; own extrusion/termination versus bought cable. Soil excavation and growing plants are later stages. | nexans-soil-heating |
| Cooking | Resistance oven/hotplate/grill/roaster with cavity/door/rack and optional fan differs from induction coil, converter, switching devices, cooling and panel. Other principal electrical mechanisms require their actual architecture, not an unsupported exclusion. | ti-induction-2013; rangemaster-quick-guide |

For own metal work collect cutting/pressing/forming, joining, wash/preparation and actual coating/enamel cure separately. For resistance heaters collect actual wire winding, bare-wire block assembly or sheath fill/compaction/seal and acceptance; PTC manufacture requires grinding, mixing, pressing, sintering, contacting and coating with each actual dopant and reaction release. Own cable production requires conductor preparation, actual insulation/jacket extrusion and termination. Own polymer production collects moulding/drying/regrind or reactive mixing/foaming/cure with its actual recipe and control outlets. Own induction/control work requires winding/insulation, PCB population/soldering, power-device and cooling assembly and test. These actual suboperation records feed their declared process group without overlapping bought complete-module boundaries.

The cards below are conditional identity-specific collection patterns, not a mandatory recipe. Verify each actual grade/formulation and supplier interface; add one card for every actual unlisted resin, blowing agent, device, fuel, waste or elementary species. A BOM-complete finished bought module includes its embodied metals/polymers/electronics once; own-process cards apply only outside that supplier boundary. Internal fabricated subassemblies are paired transfers that cancel in the rolled-up inventory. Never interpret unlisted or unresolved flows as zero.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| allocation_direct | factory outputs | Separate configuration-specific lines and meters first. Allocate remaining common loads using measured causal drivers such as occupied test time or machine cycle energy; document driver and period. Never average different apparatus configurations by unit count alone. |  |
| allocation_reject | rejects and rework | Accepted-product production carries attributable reject/rework/test burden. Scrap is a separate waste or evidenced co-product at its actual interface, not negative virgin metal or an automatic avoided-burden credit. Declare allocation method if a genuine saleable co-product exists. |  |

## 8. Foreground Data Collection, Calculation, and Quality Rules

For a single configuration and one reconciled period, collect Q as each attributable exchange total including rejected production and rework; N as accepted complete units; total accepted calibrated net mass as the sum of their individual masses. M equals that sum divided by N; q_item = Q/N and q_ref = Q divided by that same total accepted mass. Rejects, test water and transport packaging never enter this denominator. No numeric equipment mass, yield, lifetime or intensity default is supplied.

### Data Collection Protocols

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| cp_mass | test | reference output | foreground records | model; configuration; serial number; accepted net mass M; accepted count N; calibration; acceptance date | Weigh the accepted complete machine on a calibrated scale, excluding transport packaging; reconcile the same configuration and acceptance record. | kg | each lot and meter interval | same complete reconciled production period | actual site and one configuration | accepted net mass per machine | calibration, source records, sampling and uncertainty |
| cp_exchange | all | physical exchanges | foreground records | lot; supplier; BOM line; grade; recipe; supplied state; gross/net mass; own assay; moisture; stocks; rejected quantity; return; upstream boundary | Reconcile calibrated scales, invoice/stock movement and complete supplier BOM; sample each physical material stream on its own basis. Record each actual unlisted atomic input/output separately. | kg | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable exchange / accepted machines | calibration, source records, sampling and uncertainty |
| cp_utility | all | electricity | foreground records | site import; generation; export; storage change; every process/test meter; meter units; calibration; period; voltage; provider; causal driver | Read synchronized calibrated site and submeter records; reconcile already assigned loads and allocate only unassigned residual. Investigate negative residuals against period, units and combined uncertainty; never clip them to zero. | MJ | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable electricity / accepted machines | calibration, source records, sampling and uncertainty |
| cp_water | all | water streams | foreground records | each volume; own temperature and density; each moisture; opening/closing stock; paired internal return; reaction water; evaporation; discharge; each stream assay | Measure all applicable water inputs and outlets with calibrated meters/scales and stream-specific sampling; close water including wet materials, reactions and inventories. Internal test recirculation is one paired transfer, not repeated purchase. | kg | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable water exchange / accepted machines | calibration, source records, sampling and uncertainty |
| cp_solvent | fabrication | acetone | foreground records | input purity; stocks; product retention; recovered solvent; capture-media mass and own loading; actual destruction; wastewater solvent; stack/fugitive species | Measure acetone on each own stream basis. Capture into carbon is not destruction; recovery and retained liquid/sludge are non-air destinations. Measure after-control stack acetone as its own concentration × synchronized matching dry/wet gas flow × sampling period, plus independently measured or reviewed fugitive release. Record gas basis, control outlet, units, calibration and uncertainty for each term; never label unexplained mass residual as air emissions. | kg | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable solvent exchange / accepted machines | calibration, source records, sampling and uncertainty |
| cp_heat | services | purchased heat | foreground records | supply mass; supply enthalpy; return mass; return enthalpy; common enthalpy datum; gross/net meter status; meter and allocation evidence | Meter supply and return independently: each own kg times own MJ/kg on a common datum. For gross imported heat subtract actual return energy once; retain certified net supplied heat without another return subtraction. | MJ | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable heat / accepted machines | calibration, source records, sampling and uncertainty |
| cp_fuel | services | natural gas | foreground records | fuel mass or metered volume; own pressure/temperature/density; composition; calorific basis; burner; control; stock | Record actual on-site combustion and fuel provider; purchased heat upstream fuel belongs in its supplier dataset. Preserve each fuel separately. | kg | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable fuel / accepted machines | calibration, source records, sampling and uncertainty |
| cp_emissions | all | species releases | foreground records | species; outlet/compartment; concentration; dry/wet gas flow; period; sampling; control; oxygen/reference corrections; species mass versus equivalent reporting; uncertainty | Use synchronized species-specific measured concentration and gas flow or independently reviewed route-specific evidence. Separate NO, NO2 and NOx-equivalent; carbon balance closes carbon but does not infer CO/NOx. | kg | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable species release / accepted machines | calibration, source records, sampling and uncertainty |
| cp_transport | dispatch | freight | foreground records | net shipped payload; each distance; truck; actual leg; load factor evidence; duplicate supplier transport boundary | Use actual shipping documentation and route distance, payload mass times distance; avoid a leg already included by supplier. Packaging transport mass is separate from net reference denominator. | t·km | each lot and meter interval | same complete reconciled production period | actual site and one configuration | attributable freight / accepted machines | calibration, source records, sampling and uncertainty |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalize_mass | all inventory rows | q_ref = q_item / M; q_item = exchange amount per one accepted finished machine; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| dq_period_normalization | raw period collection and all applicable exchanges | For the SAME configuration and reconciled period collect Qattr (each attributable exchange including reject/rework/test burden), Naccepted (accepted complete units) and Dnet (sum of calibrated accepted net masses). M = Dnet/Naccepted; q_item = Qattr/Naccepted; q_ref = Qattr/Dnet. Reject, packaging and test-water mass are excluded from Dnet. Retain raw Qattr native numerator units and exact conversions; never average across configurations. | synchronized meter/stock, calibrated serial-mass and acceptance records |
| dq_configuration | whole inventory | Retain drawing/BOM/test/configuration linkage, complete make/buy ledger and actual grade/provider. No cross-configuration denominator. | acceptance and supplier records |
| dq_uncertainty | physical balances and utility residuals | Investigate closure with actual combined measurement, sampling and allocation uncertainty. No universal tolerance, assumed yield or unmeasured loss-to-air. Match assays separately for product, scrap, slag, sludge, wastewater and release when present; account reactions/stocks and cancel paired internal transfers. | balance workbook and uncertainty budget |
| dq_gaps | identity and range gaps | Specific chemical recipes, grades, bought module supply providers, wastes and elementary UUIDs remain unresolved until direct-read qualified. No empirical mass, factor or range is adopted. Conditional absence requires actual architecture evidence; unknown remains unknown. | qualified data and gap disclosure |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| validate_scope | reference identity | Confirm full product function and actual architecture; resolve uncertain industrial/hybrid principal-function assignment. Generic UUID does not prove every variant. | unsd-cpc3-2025; stiebel-storage-hybrid |
| validate_mass | reference output | Validate calibrated accepted net masses and count in one configuration/period, output 1 kg, and all applicable exchange conversions; packaging/rejects excluded from denominator but their attributable burdens included. |  |
| validate_routes | make/buy and conditions | Trace all actual modules/grades/recipes and missing atomic cards. Complete purchased module and its embedded material/process burdens are counted once; actual other electrical architectures require review and collection, not silent exclusion. | ti-induction-2013; tdk-ptc-2026 |
| validate_balances | physical materials/water/solvent | Reconcile each own assay/density/moisture/reaction/stock and paired return. Include retained/recovered/captured/destroyed solvent and all non-air destinations; capture is not destruction and residual is not an emission. Investigate mismatch against measured combined uncertainty. |  |
| validate_utilities | all process and shared meters | Reconcile same-site-period purchased imports, generation, exports, storage and process/test loads. Residual-only services cannot add whole-site totals again. Heat gross/net status and independent own supply/return enthalpies must be documented. |  |
| validate_species | direct releases | Match species/compartment and controls; NOx-equivalent cannot masquerade as NO2 mass. CO and NOx require independent species evidence beyond fuel carbon. Missing identity, provider or amount blocks a complete concrete data package. |  |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Foreground equipment-production data package; process and lifecyclemodel are downstream projections |
| downstream_use | secondary_dataset; background_dataset after qualified review |
| allowed_use | Same specified apparatus/configuration, production route, supplier interface, site and period |
| excluded_use | Generic use-phase heat/food service or lifetime comparisons; unsupported cross-route substitution |
| required_metadata | All reference qualifiers; boundary/make-buy ledger; test/reject basis; upstream/waste providers; allocation; measurement records |
| required_quality_disclosure | Candidate status; unresolved classifications, UUIDs, grade/recipe/provider and empirical ranges; conditional not-applicable evidence; combined uncertainty |
| update_trigger | Design, mechanism, supplier grade/recipe, site, meter interface, test requirement or category evidence changes |
