Maybe would be nice to do as a graph showing where various developments branched off e.g. lightweight heat exchangers from cast iron, combis from heating-only etc?

Anybody know when building regs changed obliging non-permanent pilot light designs? --John Stumbles 16:31, 21 February 2007 (GMT)

Somewhere before the 1/4/2005 upgrade to Part L. It must have been the inspriation for the retro fitting of electronic ignition to models like the Kingfisher and Mexico. --Makewrite 20:20, 21 February 2007 (GMT)

I think the natural draught flue variants were always available it was just the proportion of installations that shifted away from using a chimney. --Makewrite 20:22, 21 February 2007 (GMT)

The Pott. Netaheat was unique in using a heat sensing mecury vapour phial to detect the pilot light. The are many models which have a two stage ignition with a pilot and main gas valve. --Makewrite 20:38, 21 February 2007 (GMT)
