The Glow Worm Majorca with the McLaren gas valve for one. Most
Vulcans. Most cast iron sectioned boilers that ended up leaking at the
seals. The Chaffataux boiler with no electrics and a pressure operated
valve like a multi-point to bring the burner in. Many Glow Worm
Fuelsavers. All the early Vaillant combis. Boy there was some dross
out there.


I've got a 20-year-old Fuelsaver. Mind, it is on its third fan...
