Rated People and Nathan James Van Gambling, better known as @betateach on Twitter, have come together to produce a video series aimed at championing the industry to consumers as well as engaging and educating installers.

In the show's second episode, Nathan talks about the difference between plumbers and gas engineers, and explains how a boiler safety check is different to a boiler service with the help of Paul Hull (@PaulRHull), Ian Briggs (@irbheating) and Jen Murphy. Nathan also pits his guests head to head in the Ballcock Challenge, which he plays with his students, to see who can put together a float valve the quickest.
