    New build - ventilation

    Thank you, I thought the same. Not sure how they're going to get around the kitchen fan, no wall space. I was aware of the 1/20th floor area but that was years ago, I wasn't sure if regs had changed. Cheers anyway.

    New build - ventilation

    Hi all, I've purchased a new build, (2 bed semi, timber framed). The builders are on finishing over the next couple of weeks. The bathroom is internal upstairs, no windows. The electrician has fitted an extractor fan in the ceiling, but today I went up in the attic and pulled back the fibreglass...

    Drayton Motorised Valve - See Pictures

    Why? 36 years in the game and I'd say the Drayton is more reliable than the Honeywell.

    Backflow from cylinder to central heating boiler

    What you are looking for is something called a featherweight check valve. They used to be fitted on gravity HW/pumped heating systems to stop the upstairs rads getting hot in the summer. You should find one on the web.

    IS anyone familiar with Primatic cylinders?

    http://www.rangecylinders.co.uk/product-primatic.html Always hated them, every one I've drained has been fithy with red rust and sludge from inter-mixing.

    IS anyone familiar with Primatic cylinders?

    Andy, I apologise and stand corrected. Just been on the Range site and it appears they can be pumped. I don't remember seeing one in 30 years, but there again my memory is shot :D :oops:

    IS anyone familiar with Primatic cylinders?

    Andy, you say Primatics can be pumped, I assume you mean the radiator circuit, that's ok. But not on the primaries to the cylinder, on the flow this would block the path of the open vent and on the return it would block the path of the 'cold feed' back to the boiler. Edited and humble pie...

    Ideal logic+ installation

    I was having a laugh. :wink: Fitted a few E types, Concords, Mexicos and W's years ago when they were robust. Then came the electronic age. I must admit I did fit one Icos 4 years ago as it was the only one to fit in the space. I still sh*t myself every time the phone rings. :lol:

    Ideal logic+ installation

    Funny thread. :D :D :D For what it's worth, I've fitted tens of thousands of Ideals and never had a single callback. I love 'em. :lol: :lol: :lol:

    IS anyone familiar with Primatic cylinders?

    Andygasman, not sure where you get your info from, but primatics were for gravity primaries only, the heating circuit may of course be pumped. As for the 2 port going after the tee for the feed or vent. They do not have a feed or vent on the primaries. They are called single-feed or primatic...

    Discreteheat - A few people on this forum have used this stuff and found it a disaster. Poor fit and finish.
