measured against a 12 % forecast — hospital, July 2026 (boilers built 1991): €118,890 saved per year, payback 0.54 years

19.69 %

measured against a 10 % forecast — automotive branch, April 2026, on a condensing boiler already at 99 % efficiency

> 500,000

data records from the 2019–2021 long-term study: identical boilers compared — the 10 % forecast was consistently exceeded over two years

In 100 % of documented cases, the forecast given beforehand was exceeded by the later measurement. Our forecasts are deliberately conservative — so the number in the quotation is the number you can rely on.

How we do it

An installation in pictures — two boilers, two days.

Hospital, July 2026: two large boilers (built 1991) receive the Intensatec high-temperature ceramics — documented from first opening to final sign-off. No conversion, no intervention in the boiler: the ceramic elements are placed, aligned, done.

How we measure

Traceable down to the cubic metre.

Every measurement run includes time-stamped proof photos of the meter readings — before and after, on the same instruments, at documented load. Any engineer can recalculate the values in the protocol. Two recent cases:

Case 1 — hospital (July 2026)

Two boilers built in 1991 · measurement runs on 30 June (without ceramics) and 1 July (with ceramics), identical time windows.

We have done this many times

From ten years of installation records.

Different plants, different sizes, different industries — the same principle. From three-pass boilers to large plants, installed in one day during a maintenance window.
