Other non-electric water heaters

1. Scope and Applicability

This PCR covers complete other non-electric instantaneous or storage water heaters in their declared supplied configuration. Gas-fired instantaneous and storage designs are distinct; actual oil/other-fuel or indirect heat configurations require their own function, heat-source interface and supply-list evidence. Electric ignition, controls, fans and pumps can be auxiliary components of a non-electric heating architecture. A generic tank, exchanger, burner or solar-ready tank is not automatically a complete category output. Mass normalizes manufacture and does not make unlike water-heating services equivalent. Sources: un-cpc-44827; wco-hs2022; rinnai-condensing; bw-gas-storage; bw-indirect; bock-oil.

CPC 3.0 44827 explicitly references HS 2022 8419.11 (instantaneous gas) and 8419.19 (other); solar water heaters are 44826/8419.12, electric heaters 44817 and central boilers 44825. HS84.19 places non-electric instantaneous/storage water heaters in a separate phrase after a semicolon from general non-domestic thermal machinery. The CPC domestic parent heading cannot on its own prove domestic-only coverage of every HS-linked item. Declare domestic/commercial/industrial intended function and review doubtful industrial/multi-service hybrids, boiler combinations, generic indirect tanks and separate heat exchange units/parts against their actual supply state.

Rinnai documents a condensing tankless gas appliance with included isolation/relief kit and distinct installer-supplied venting. Bradford White gas storage documents enamel lining, anode, foam and convertible gas control, while its indirect model documents a glass-coated carbon-steel coil and boiler supply/return without asserting a burner. Bock oil storage documentation lists a shipping weight excluding burner/controls, so completion of the supplied heater must be checked. These are contrasting product facts, not one universal gas-model recipe. Separately supplied components and STIEBEL solar-ready hybrid tanks are adjacent counterexamples (stiebel-hybrid-adjacent); Rheem solar/boosted units are adjacent rather than automatic other-heater identity (rheem-solar-adjacent). Catalogue capacity, nominal fuel input, shipping weight, efficiency, warranty, lifetime and temperatures are not factory production defaults.

How much	1 kg accepted net complete machine mass of the same configuration
How well	Meets actual hydraulic, combustion, pressure, leak, safety and declared acceptance requirements
How long or cycle	One manufacturing/delivery period; no default lifetime

Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	principal function and domestic/commercial/industrial market; actual classification/supply boundary; model/revision; instantaneous/storage; actual gas/fuel/indirect source; condensing/non-condensing; tank/coil/burner make-buy; corrosion lining/anode/insulation formulation; vent/fan/controls; included vs installer accessories; actual retained fill; pressure/leak/burner/electrical factory acceptance; calibrated net mass/common-period accepted N; providers/geography/voltage/units; species/compartment and uncertainty

Declare every qualifier in the package; complete-category reference identity matched, but actual supplied state/principal function still requires verification. Mass does not establish equivalent user heat service.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass	kg	M = accepted net mass of one complete machine of the same configuration in kg; collect using cp_mass.
physical_basis	material/water/species	Mass	kg	Each term uses its own assay, moisture, wet/dry basis, measured temperature/density, stocks and reactions; gross mass is not contained element.
gas_state	test gas	Volume	m3	Declare meter reference state and actual T/P/humidity; mass/volume conversion uses actual composition/density, never power-plant case factors.
energy_interface	energy	Delivered energy	MJ	Electricity 1 kWh=3.6 MJ. Heat supply mass times own enthalpy minus independent return mass times own enthalpy/common datum; gross subtract return once, already-net never twice.

5. System Boundary

rule_id	Applies to	Rule	source_ids
gate	foreground	Include receipt, actual site fabrication/corrosion/insulation, integration, factory acceptance/rework, services, wastes and packing to accepted release.	rinnai-condensing; bw-gas-storage; bw-indirect; bock-oil
make_buy	supplier_interface	Bought complete tank/burner/exchanger/controller embeds its upstream materials and operations once. Own fabrication uses feedstocks and actual operations instead. Partial supplied modules disclose remaining work. Pair internal transfers and count each burden once.	rinnai-condensing; bw-gas-storage; bw-indirect; bock-oil
factory_use	production	Include actual factory hydrostatic/leak and burner/function test water, gas/oil/electricity and losses; separate retained shipped fills and accessories. User fuel/hot water, installation vent/pipe/commissioning and use-phase condensate are outside factory production. Manufacturer installer instructions do not prove factory test amounts.
bom_extension	route	Atomic cards are conditional anchors, not a universal recipe. Add each actual grade, coating ingredient, foam precursor/blowing agent, weld gas, fuel, accessory, fill, waste and emitted species; require actual formulation/assay and route. not_applicable requires absence evidence; unknown is not zero.
upstream	links	Actual upstream production/transport and external treatment links need supplied state/geography/period. Supplier boiler fuel embedded in purchased heat is not onsite combustion; no complete cradle-to-gate claim before missing providers are resolved.

Boundary Abstraction

Field	Value
declared_starting_condition	Actual input grade/completed state and supplier delivery interface
starting_condition_role	Factory receipt boundary
product_classification_scope	Complete other non-electric water heater, actual principal function and supplied state reviewed
recursive_input_rule	Same-category bought precursor upstream once; subsequent site work only; paired internal transfers cancel
upstream_dataset_requirement	Actual grade/formulation/state/provider/geography/period; link complete bought units without expanding embedded material twice
disclosure	make-buy; complete supply list; site process; test fuel/water; retained fill; installer exclusions; classification gaps; denominator/uncertainty

Architecture and supplied-state matrix

Configuration	Actual fabrication/integration	Limits
Gas instantaneous	Actual burner, exchanger, ignition, gas valve, sensing, vent/fan and conditional condensate path	No storage tank imposed; condensing and non-condensing need actual metallurgy and architecture
Gas storage	Actual vessel/flue, lining, anode, insulation, jacket, burner and controls	Manufactured-home roof-jack source is a specific configuration, not default supplied kit
Oil/other-fuel	Actual supplied burner/fuel pump/combustion interface and vessel/exchanger; add each real fuel/species	Bock shipping weight excludes burner/controls; use weighed complete supply state; other-fuel recipe unresolved
Indirect/hybrid	Actual heating coil and external heat supply/return, tank and controls; actual backup declared	Generic coil tank, separate exchanger, central boiler and solar-ready/electric backup hybrids need classification review; no compulsory onsite burner

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
causal	site	Separate configurations and subdivisions first; allocate common residual by measured causal load, operating time or appropriate physical driver, retain numerator and denominator records and uncertainty. Do not average unrelated non-electric heater configurations or use heater mass automatically for every utility.
rejects	accepted	Include actual rejects, rework and qualification burdens in attributable Q for accepted output; only accepted net mass/count enters denominator. Segregate recycling transfer and treatment; do not assume avoided-product credits or zero upstream recycled burden.

Raw-period protocol: N is accepted count of the same configuration, D the sum of calibrated accepted net masses, M=D/N. Each Q is the attributable common-period exchange including reject, rework and factory-test burden; first q_item=Q/N then q_ref=Q/D. Packaging/reject mass stays out of D. Retain actual original units, own composition, stocks and reaction records.

complete_bom	actual configuration	Cover all actual exchanges; separate make/buy/accessories/fills/test charges; gaps explicit	actual BOM/routes/suppliers
mass_period	cohort	Same configuration/period/acceptance, calibrated mass/stocks; no cross-configuration mean	calibration/period ledger
balance_uncertainty	physical balances	Own water fraction/density/assay/reactions/paired returns; compare combined uncertainty	measurement/sampling/reaction/allocation evidence
cohort_raw	common-period records	Naccepted, Dnet and Qattr share configuration/period. Dnet sums calibrated accepted net masses; M=Dnet/Naccepted, q_item=Qattr/Naccepted, q_ref=Qattr/Dnet. Qattr includes rejects/rework/factory tests; Dnet excludes packing/rejects/consumed test media; preserve each native numerator unit.	actual period/calibrated acceptance ledger
species_sampling	air or liquid releases	Post-control species concentration times matched same-period gas/liquid flow or integrated duration; correct temperature/pressure/wet-dry/units; fugitives independently measured. Carbon closure cannot derive CO/NOx; NO2 not NOx-equivalent.	actual sampling/flow/period/state records
provider_gaps	links	Each actual upstream/treatment matches state/geography/period; unverified not complete footprint	direct records/substitution disclosure

9. Validation Rules

rule_id	Applies to	Rule	source_ids
identity	dataset	Confirm principal function, intended market, model/revision, delivered configuration and activated architecture. Every actual exchange needs matching identity/property/unit/provider; absent, zero and unknown remain distinct.
denominator	all inventory rows	All inventory uses the same accepted cohort and common period. Verify calibrated accepted net mass and N; reject and packaging mass excluded. Check q_item=Q/N then normalization by same mean M; mixed configurations are invalid.
double_count	make_buy	Reconcile complete bought modules versus own materials and operations, retained fills/accessories versus factory consumption, paired internal transfers and external inputs. Count each actual burden once.
water_close	physical water records	For each term use its own measured water fraction, density and wet/dry basis: fresh and input moisture plus reaction water and beginning stocks minus final stocks, retained product, discharge and evaporation; internal returns cancel paired. Investigate measured closure against combined sampling/meter/allocation uncertainty; no universal tolerance.
species_close	material and chemical records	Close each contained metal/chemical separately using each input, product, scrap, sludge, liquid and release own matched assay and dry/wet basis, reaction stoichiometry and stocks. Gross mass is not contained element. No all-inventory mass rule applies to energy or transport.
solvent_close	solvent records	Distinguish retained solvent, recovered return, captured liquid/media, demonstrated destruction, wastewater/non-air residual and actual species air release. Capture is not destruction; an unexplained residual must be investigated, not assigned to air.
utility_close	energy records	Reconcile purchased imports, actual on-site generation, exports and storage changes with assigned fabrication/integration/test/dispatch loads in the same period and units. Shared row ONLY unassigned residual; investigate negative residual against period, unit and combined measurement uncertainty without clipping.
steam_close	steam and condensate	Use supply kg times supply own MJ/kg and return kg times return own MJ/kg at measured pressure/temperature relative to common zero. If gross supply, subtract return once; if already-net invoice, do not subtract again. Keep physical steam/condensate mass balance independent from energy.
species_emissions	air releases	Validate every emitted species and compartment independently. Fuel carbon balance cannot alone establish CO or NOx. NO2 mass is not NOx reported as NO2 equivalent; keep reporting conventions and actual species identities distinct.
