Martin Wadsworth walked into the Den in Season 6, Episode 7 in the episode that aired 1 September 2008. Discrete Heat, the heating system behind skirting boards, pitched in the Other category, one of 902 other businesses to brave the Den across all 21 seasons.

On the carpet, the number was £150,000 for a 10% stake, which valued the company at £1.5M.

The dragons passed, and Discrete Heat left without a deal. That's not always the end of the story. Some of Dragons’ Den's most successful companies were rejected on air and grew anyway, using the exposure (the "Dragons’ Den effect") to drive sales the dragons missed out on.

Discrete Heat was one of 66 businesses to pitch in Season 6, where 14 deals got done. In the Other category overall, roughly 11% of pitches have landed a dragon across the show's history.
