Congrats, Gebwell: first EPD lands

What Gebwell just published

Gebwell’s first Environmental Product Declaration covers the G‑Energy thermal tank used for domestic hot water and space‑heating systems. It reads as a product‑specific declaration for a thermal storage tank, with scope language that matches common hydronic installs. Publication month is January 2026 under the program operator EPD Hub.

Key basics in plain English. One EPD so far. Category is domestic storage water heater and thermal storage for hydronic systems. The document names the applicable product rule set as Individual and standalone domestic storage water heater.

Why this matters in specs

Thermal storage tanks show up on a lot of mechanical schedules. When a product lacks a product‑specific EPD, design teams often apply conservative defaults that make submittals harder and slow down approvals. A verified declaration removes that penalty so selection can hinge on performance, delivery, and price instead of assumptions. For LEED v5‑oriented projects, that transparency is quickly becoming table stakes rather than a nice‑to‑have.

A quick look at who Gebwell serves

Gebwell manufactures hydronic heating solutions from Finland, including heat pumps, energy storage tanks, and district‑energy gear for residential and light‑commercial buildings. In short, the EPD covers a part that sits in the middle of real‑world plant rooms where specifers compare like‑for‑like equipment every day.

Program operator at a glance

The new declaration is issued by EPD Hub, a program operator that verifies Type III EPDs aligned with EN 15804 and ISO 14025. For manufacturers, that means the document can live in common European discovery channels and meet the formatting buyers expect.

Competitive snapshot

Viessmann has product‑specific EPDs visible for several Vitocell hot‑water storage tanks in European registers, so Gebwell’s tank EPD helps close a known gap against an established brand. See this quick read on Viessmann for context on where their declarations show up.

Norway’s OSO Hotwater publishes a product‑specific EPD for the SAGA S domestic electric water heater with EPD International AB. That indicates declared coverage for a close adjacent in the same decision set.

Stiebel Eltron appears without a current tank EPD in EC3 as of today, which gives Gebwell an edge when a project team filters for products with verified declarations in hydronic storage.

Scope notes that help sales and engineering

Based on the public record, this is a focused product entry for a thermal tank, not a broad portfolio roll‑up. If the internal plan is to extend coverage, the most natural next steps are adjacent sizes within the same tank line, followed by primary heat‑source pairings where the tank is sold bundled with air‑to‑water or ground‑source units. That mirrors how buyers evaluate systems.

Can we find the EPD on Gebwell’s website

We did not locate the new thermal‑tank EPD PDF on gebwell.com at the time of writing, though the site does explain what an EPD is and references past declarations for other products. Adding the PDF to a visible sustainability or product page helps spec teams self‑serve and reduces email back‑and‑forth. Good visiblity wins time. Company EPD overview page.

What smart teams do next

Publish adjacent sizes in the same tank family to match how schedules are written. Map the declaration to the product page and distributor portals so submittals are one click away. If heat pumps are core to the line, sequence those next under the same or a region‑preferred operator so comparison stays apples to apples.

Takeaway for product and sales teams

Gebwell has entered the transparency arena with a credible first step in thermal storage. That keeps them in more conversations against brands that already declare and creates daylight where others still do not. One document will not win every bid, yet it removes a common blocker and makes every future release easier to adopt across specs.
