Product Data for Heating: Performance Figures and Compatibility

Heating is a technical-figures business: output, efficiency and ErP class decide the sale, and most of it hides in PDF datasheets. Here's where the SHK standards help, where they stop, and how to turn datasheets into structured data.

☝️Key takeaways
  • Heating products are defined by technical figures: kW output, efficiency, ErP energy label, flow temperature — not by marketing copy.
  • Most of that data arrives as a PDF datasheet, not a clean feed — and reading it by hand does not scale.
  • Standards like DATANORM, IDS/UGL and ETIM cover core master data, but rarely the full spec depth, the compatibility matrix or the sales content.
  • Productbay reads datasheets with AI into structured attributes and models component compatibility — the two things heating data really needs.

A heat pump is not sold on a nice photo. It is sold on its output at a given flow temperature, its SCOP, its ErP energy class and its sound power level. A radiator is chosen by its heat output in watts at a defined temperature spread. A controller only matters if it talks to the boiler it sits next to. Heating is a category where the product is its technical figures — and where those figures decide whether a customer, an installer or a planner even considers the article.

Product data for heating is performance data plus compatibility: kW output, efficiency, ErP label and the relationships between components. That is the whole challenge of this article. Heating is a sub-branch of the broader plumbing & heating (SHK) world, and it inherits that world's standards — but it adds a layer of technical depth that a plain classification never carries.

Why is product data for heating so hard to get right?

The core reason is where the data lives. For most consumer goods, a supplier feed carries the attributes that matter. For heating, the attributes that matter are locked in a PDF datasheet:

  • Performance is multi-dimensional: a heat pump has different output and COP at different flow temperatures — a table, not a single number. A radiator's output depends on the temperature spread. One figure is never enough.
  • Regulated figures: the ErP energy label and efficiency class are mandatory selling data, and they have to be correct — a wrong ErP class is not a cosmetic error.
  • Compatibility is a system property: a boiler, its controller, a buffer tank and the flue accessories only sell together. If the compatibility data is wrong, the wrong basket ships.
  • Source format is the problem: manufacturers publish the good data as a datasheet PDF, sometimes an ETIM export, rarely a clean feed with every attribute filled. The gap is filled by hand.

Do this manually across dozens of suppliers and it does not scale. The route out is the same as for any multi-supplier catalog: consolidate, normalize, enrich and publish — but here the enrichment step has to reach into datasheets.

Which standards apply to heating — and where do they stop?

Heating does not float free; it sits inside the SHK trade's data landscape. Several standards apply, each covering one layer and stopping at the next:

Data layerWhat the standards deliverWhere it stops
Core master dataDATANORM, IDS/UGL formats carry number, price, base dataNo deep performance figures or datasheet detail
Technical classificationETIM groups articles and defines attribute setsAttribute values often empty — the class exists, the data doesn't
Energy figuresErP / energy label mandates efficiency & classDelivered as a label PDF, not always as structured fields
CompatibilityFitting tables, sometimes in manufacturer docsRarely machine-readable; lives in PDFs and reps' heads
Sales contentNot the job of a data standardDescriptions, benefit copy, images absent

In short: DATANORM, IDS/UGL and ETIM give you a clean skeleton — a number, a price, a class — and the ErP rules tell you which figures must exist. What none of them reliably delivers is the filled-in spec depth of a datasheet, a machine-readable compatibility matrix, or ready-to-publish content. That is exactly the layer heating retail has to build itself.

How does Productbay turn datasheets into structured data?

The throughline is a three-step job, aimed squarely at the PDF problem — and that is what Productbay is built for:

  • Consolidate: import every source once — DATANORM/IDS export, supplier CSV, Excel, ETIM file, feed URL, FTP, API — and match by article number or GTIN/EAN so existing products update and new ones are created.
  • Enrich from PDFs: AI reads the PDF datasheet, extracts output, efficiency, ErP class, dimensions and connection sizes into structured attributes, writes descriptions, assigns ETIM-aligned categories and translates via DeepL — always with a review queue before anything publishes.
  • Model compatibility & publish: link heat generators to their compatible controls, tanks and accessories as structured relationships, store images and label PDFs in the DAM, then sync two-way to Shopify and Shopware and connect ERPs like Xentral or weclapp — each with per-channel transformations.

Crucially, Productbay starts where the standards end: it takes the datasheet the ETIM class never filled, the compatibility that lived in a PDF table, and the content no standard provides, and turns them into filterable product data. Productbay is built for specialist retailers running multi-supplier, multi-channel catalogs — from mid-sized shops to large chains.
