I've had a lot of callouts through him, most of which have turned into bigger jobs and regular customers. However, his website does give some shocking "advice"! And seems to be written by a 3 year old...
" In the days where there were not many guidelines but enough deaths to sit watching the 6′oclock news and keep your mind occupied with what going on were the day when you most likely have an open fired boiler, rather than the closed room vented boiler. Martin still believe that we are still in those days as the full guideline we aim to target are not met. Just below we give you an understanding of what the difference is between the vented and unvented boiler before you go out and buy possibly what is known as the second hand boiler or a bas bottle open fire that keeps you warm with not the right amount of ventilation."
