Elmhurst reference data

Lookup tables to support re-keying certs into the Elmhurst RdSAP entry tool (see scripts/hyde/ and the expand-sap-accuracy-corpus skill).

pcdb_gas_oil_boiler_codes.csv

Every gas/oil boiler in the SAP Product Characteristics Database (PCDB Table 105), one row per boiler, so you can look up the Ref No to type into Elmhurst's PCDF boiler Reference field (Space Heating → 🔍 search → Select).

Columns: pcdb_id (the Ref No), brand, model, qualifier, type (Regular / Combi / Combi-storage / CPSU), winter_eff_pct, summer_eff_pct, output_kw_max, final_year.

• Generated from domain/sap10_calculator/tables/pcdb/data/pcdb_table_105_gas_oil_boilers.jsonl.
• type is decoded from the raw PCDB row's boiler-type code (raw[14]: 1→Regular, 2→Combi, 3→Combi-storage, 4→CPSU). This is the field that decides whether Elmhurst wants a hot-water cylinder (Regular) or not (Combi).
• Find a boiler: grep -i "ecotec pro,28" pcdb_gas_oil_boiler_codes.csv or filter by brand/model; the cert's lodged main_heating_index_number is the pcdb_id.

Note on entering it in Elmhurst: the on-screen PCDF boiler Reference text box is editable and will display a number you type, but typing alone does NOT re-resolve the boiler — its type/efficiency/cylinder behaviour stays from the previously-selected boiler. Only selecting via the 🔍 search dialog genuinely sets the boiler. This CSV tells you which Ref to pick.
