IRSAP radiators and EPDs: where things stand
IRSAP is a design‑forward radiator maker with a sprawling catalog and a growing smart‑heating line. If their products show up in your specs, the next question is simple. How visible are IRSAP’s enviromental proofs today, and where are the quick wins to unlock more bids that expect third‑party EPDs?
Company snapshot
IRSAP, based in Italy, focuses on space heating and bathroom comfort. The brand’s core is hydronic and electric radiators, towel warmers, and fan‑assisted decorative units, plus the IRSAP NOW smart controls platform for thermostats and radiator valves. Their site also highlights an active sustainability track, including ISO 14001 and a Product Carbon Footprint for a TESI model, which is not an EPD.
Product families, at a glance
Think of IRSAP’s range as three layers. The first is heat emitters like tubular TESI, panel and design radiators, and bathroom towel rails. The second is performance variants such as fan‑assisted Relax models and hybrid heat‑cool units for low‑temperature systems. The third is controls, including smart thermostats, TRVs, and connectivity kits under IRSAP NOW.
How big is the catalog
Across hydronic radiators, electric towel warmers, design pieces, and ventilated or hybrid models, IRSAP plays in at least five distinct product groups. Factor in heights, depths, widths, and finishes, and the portfolio runs into the hundreds of individual SKUs. That breadth helps specifiers match retrofit constraints and aesthetics without costly redesigns.
EPD coverage today
As of February 10, 2026, we could not locate a published product‑specific Type III EPD for IRSAP radiators or towel warmers in the major public registries we checked. IRSAP does showcase an ISO 14067 Product Carbon Footprint for TESI, which signals progress, yet a PCF is not interchangeable with an EN 15804 or ISO 21930 EPD in most spec paths. See IRSAP’s sustainability section for their current disclosures.

Why it matters in specs
Many European and global projects now expect product‑specific EPDs for building materials to streamline embodied‑carbon accounting and keep submittals clean. LEED v5 is live, with credit forms delivered through Arc and a stronger decarbonization focus, which amplifies the value of verified declarations for products installed in quantity on a job (USGBC, 2025) (USGBC, 2025).
A likely bestseller without an EPD, and who beats it
TESI tubular radiators are IRSAP’s flagship and appear widely in residential and light commercial work. If a project team requests product‑specific EPDs, TESI can be traded out for a comparable multicolumn or panel alternative that already carries one. Example: Zehnder’s Charleston multicolumn radiator has a current product EPD, first published in 2024 (International EPD System, 2024) (International EPD System, 2024). In panel radiators, Stelrad’s Green Compact line also holds a product EPD published in 2025, which keeps it in play on EPD‑sensitive bids (International EPD System, 2025) (International EPD System, 2025).
Competitive set you’ll meet on projects
Common matchups for IRSAP include Zehnder Group for design and bathroom radiators, Stelrad for panel radiators in volume housing and commercial fit‑outs, Purmo Group brands in panel and decorative lines, and Cordivari or Kermi for bathroom towel warmers and designer pieces. On projects that chase transparency points or have internal procurement rules, competitors with product EPDs often get the first call.
Where coverage looks thin
The gaps are most visible in staple emitters that drive volume. Hydronic tubular radiators, panel radiators with common connection patterns, and electric towel warmers are the units most likely to appear in LEED or other carbon‑tracked submittals. Without product‑specific EPDs in those families, specifiers default to conservative database values that can hurt the product’s carbon math, which raises the swap risk.
What it takes to close the gap fast
Start with the radiators that generate the most quotes and conversions. Select the PCRs competitors already use in Europe so results are directly comparable, typically EN 15804 A2 via a mainstream program operator. Make data collection painless for plant teams with a clear bill of materials, coating and finishing inputs, packaging, utilities by month, and transport lanes. Publish the first wave of product‑specific EPDs for one tubular family and one panel or towel‑warmer family, then cascade updates model by model. Choose a partner who handles the heavy lifting on data wrangling and is operator‑agnostic so you can publish where your customers procure.
What we’re watching next
IRSAP’s PCF work suggests more disclosures are coming. The commercial unlock will arrive when their highest‑volume radiators gain product‑specific EPDs that match competitor scope and geography. That is when sales teams stop explaining around paperwork and start leading with verified numbers that clear submittals on the first pass.
Frequently Asked Questions
Does a Product Carbon Footprint replace an EPD for tenders or LEED v5 submittals?
No. A PCF uses ISO 14067 to report climate impact. Most tenders and rating systems still ask for third‑party verified Type III EPDs that follow EN 15804 or ISO 21930.
Which IRSAP products should get EPDs first to reduce swap risk?
Start with tubular TESI and a high‑runner towel warmer or panel radiator family. Those SKUs appear most often in residential, hospitality, and office retrofits where EPDs are expected.
Which program operators are common for radiator EPDs in Europe?
IBU and the International EPD System are both widely used for building products, with mutual recognition under ECO Platform in many cases.
