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

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.

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.

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
