Heat Gun

A bargain heat gun, from box to bill of materials.

Pull it apart, weigh it, name it, fix it. A teardown and eco audit, then small changes: a stainless tip, better screws, an overmoulded grip and a shell that can be sorted for recycling.

  1. ABS for cost and moulding. It softens near the tip.

  2. A NiCr coil. In use, it's where most of the energy goes.

  3. Drives air over the coil and out of the nozzle.

    Audit

    Use dominates energy and CO₂ over five years of DIY.
