    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...

    Questions about my cold water tank.

    Firstly thank you for taking time to read this for me. Last week we were lucky enough to have our second daughter born. During getting some bits out of the roof I looked at the cold water tank as it was running. I’m a complete novice at plumbing but can fix a few things. To be honest I didn’t...

    First question: What is the "ball thing" on the fourth copper pipe along. Also: I have identified the flow to my radiators as being the left-most pipe that is 22mm and the return as the right-most 22mm copper pipe (fifth one along), then the heating for my taps as the 15mm next to my radiator...

    Pipe sizing questions

    Hi all, still working on my portfolio but having a bit of confusion regarding allowances for fittings when working out pipe size requirements as I'm reading conflicting information. In college we were told to allow 0.5m for Tees and elbows and 0.3m for bends. My Viper gas handbook says the same...

    The Richard3009 questions

    This guy seems to be a right Richard! I answered (vaguely) his post earlier about what type oil hose he needed for his boiler. Now he has a post about what “ballpark” figure for oil pressure on his boiler! He has been largely just on here over a long period basically asking details of how to...

    Theoretical questions regarding low loss headers (or close-coupled tees)

    T'other day, the subject of hydraulic separation came up again on this forum and I decided it would be interesting to look at the subject again. Thinking about the kinds of design shown on this page: Why all the fuss about hydraulic separators? Closely spaced tees have worked just fine for me...

    Stupid questions from a novice

    I have a couple of stupid questions. (Actually, more than a couple, it turns out). Firstly, PTFE tape. Is it worth it (a lot of people recommend it; but many say it makes no difference. Who is right)? Is it stable enough to be used on the piping for the default radiator? What about the fittings...
