Meet the assistant

The sizing is exact. The driving is conversational.

Hi — I'm the Thermann assistant. I size commercial hot water jobs with you, start to finish.

The workflow

Three steps to a specification.

Average completion: under 4 minutes

  1. Answer.

    Pick the building type and answer only the questions that type needs. Unknowns have documented fallbacks, recorded as assumptions.

  2. Calculate.

    Sizing runs server-side on Thermann's collected data and returns eligible configurations with SKUs and safety margins.

  3. Specify.
