minute

The minute is a unit of time usually equal to 1/60 (the first sexagesimal fraction) of an hour, or 60 seconds. In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system). Although not an SI unit, the minute is accepted for use with SI units. The SI symbol for minute or minutes is min (without a dot). The prime symbol is also sometimes used informally to denote minutes of time.

    Low Mains Water Flow Rate 2 Litres A Minute!!! What Boilers/System Can I Fit??

    Hello, This is my first time posting as I'm a new member so apologies in advance if this has been covered before. I have recently done a landlords gas check at a property with only 1 gas appliance (heat only boiler) and ended up condemning it as it was ID for many reasons. The landlord asked...

    Evohome continually bringing boiler on for one minute then off for 10 minutes

    Hi When the zones are near temperature (if far away it keeps boiler fully on instead) it seems that the Evohome is bringing the boiler on for 1 minute in every 10 (as some of the zones are reporting not at 0% even though the system is reporting that it is at temperature). I believe (though not...

    Hot water call every minute

    When a hot water tap is switched on in any part of my house the pipes near the cylinder or the cylinder make a noise. This is completely normal. Recently I have noticed especially at night that this noise is happening every minute for a few seconds and no hot water is beingcalled . Any ideas ???

    Annoying noise in pipes. Intermittent approx every minute.

    Victorian house converted into 5 flats. Four flats have a persistent sound of water in the pipes sometimes followed by a knocking sound at intervals of around one minute. 24/7 even when no-one is using water. Basement flat appears not to have it but can be heard faintly on the main in the street...

    Bloody custards! The phone rings at 7.30 with a message "I've got no hot water", it's only the pressure. Now I've serviced it twice now, I didn't fit it and the boilers not in warranty. i rang back and politely asked her not to ring so early as it woke my whole family. i said I'd do it for £55 "...

    So Mrs Three Minute to get hot water... LCV

    Turns out that she was given the option of a secondary return (circulator) but it was an extra £1,200 and they decided that they'd be happy to wait for the extra seconds. There is some debate as to how long the water would take to come though but it sheds a completely different light on the...

    Hi, We live in a house that recently renovated, but not by us, so I have very little information about the way it was done. I do know however that the renovation wasn't done by experts (as I can tell from the way the electricity was done). We have two problems with our water flow. I am not...
