    Single Zone UFH Help in bathroom, so many questions

    Stanley De - Luxe 90 questions

    This thing is a bit if a mystery olto me . The boiler and the oven dials have 'Idle' marked on them, does anyone know what temp that sits at? I've discovered the boiler won't fire unless the oven is on at minimum temperature, which seems daft. There is also a Pull To Open dial/rod . I've no...

    Hi again I'm on a roll with the plumbing questions today! So here's query #2... We've not used our hot water for quite some time, and it now doesn't work. From what I can gather based on what I've learnt in the last hour or two, I think the problem is with the 3 port motorised valve. When...

    Boiler mate questions

    I am going to quote to replace this boiler mate with an unvented cylinder but have never seen one before what do the three pumps do? Boiler pump, heating system pump and? It looks like the heating system is pressurised so is it just the thermal store that’s open vent? is it copper inside? 🤓

    Vented Indirect System Questions

    Hi, First of all, apologies, I have a really annoying need to understand things in minute detail. Today my Hot Water Cylinder seemingly ran out of adequately heated water after two short showers. The cylinder was heated between 8:30am-9:30am to a temp of 60 degrees. The only use was two short...

    Automatic air vents in loft spaces: Questions

    Do you use them? And if so how long would you leave one on a system that had air in it before returning to screw down/isolate (after hoping the air would have escaped in meantime)? Get the impression some of them leak if left but don't know how common this is. Perhaps some of you leave them...

    Condensation inside Heat only boiler casing - a couple of questions.

    Hi all, I've got a British Gas 330+ Heat only boiler and it displayed an F25 error (lack of water iirc) on Sunday. I read the manual and bled the radiators (1 rad had quite a bit of air) and topped the system up a little and sure enough I could then hear water flowing back into the boiler. I...

    Questions on cooker gas fitting.

    So I've got a gas pipe in my kitchen, but due to a miscommunication on my part it's got the wrong fitting for the cooker I intend to buy. It's got a nut on the end, and is facing upwards, whereas I need a bayonet, and if I understand correctly, those should always face downwards so the rubber...

    Please can anyone answer 3 questions about central heating?

    I'd be so grateful! 1) If the water in the rads and pipes is so hot that I can't touch the rads, is it possible that I can hear it rushing and coursing through the rads and pipes? I've been told the noise is air in the system, but I'm wondering if it's boiling hot water instead. 2) When...
