Talk:Boiler Evolution
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)
A long time before 1/4/2005! I'm guessing around 20 years ago but it'd be nice to know exactly when.
Were there 'electronic' versions of the Mexico & Kingfisher? (My Ideal manuals are up in the attic and I cba to dig them out right now.) I haven't come across many Kingfishers but all the Mexicos I know are permanent-pilot-light types. --John Stumbles 00:11, 22 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)
I guessed that RS must have come along later and that something like a Pott C70/21 must have been a purely OF design. Likewise Bermudas (were there ever RS versions?) --John Stumbles 00:11, 22 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)
Ahh yes: Wait ...... clunk! I still come across a few of those. --John Stumbles 00:11, 22 February 2007 (GMT)
