It doest apply at all Battle, thats purly for sytems with a cylinder, unvented systems still need to follow the 'last tee' rule for control over the hot water, you can tee off anywhere on a combi system,  |

another inovation by a firm i worked for ( servowarm) was the 'no vent' system, they would use a 22mm cold feed, this made it immpossible to suck down and get air in the system, as far as i know there were never any issues with it, In fact using the earths own atmosphere as the expansion vessel !!! I have come across this before at a mates house and must confess that I was a little bit worried that the boiler had no expansion pipe, but in the end I decided it was alright as everything was working. If I altered it I would have more than likely fuck it all up. Last year he had is boiler moved and the RGN he employed didn't like it one bit, so he fitted an expansion vessel and converted it all to a pressurised system. He certainly took his chances on the fittings and radiators holding!!! |

Was the lever valve also known as the summer valve?

No, it was a manual valve normally fitted in the cylinder cupboard with hot water fully on/central heating off at one end to central heating fully on/hot water off at the other.
You moved the lever yourself (the customer) manually towards either end depending on how much heat you wanted going to the radiators or hot water circuits.
