time
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions.Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second, which is defined by measuring the electronic transition frequency of caesium atoms. General relativity is the primary framework for understanding how spacetime works. Through advances in both theoretical and experimental investigations of spacetime, it has been shown that time can be distorted and dilated, particularly at the edges of black holes.
Throughout history, time has been an important subject of study in religion, philosophy, and science. Temporal measurement has occupied scientists and technologists and has been a prime motivation in navigation and astronomy. Time is also of significant social importance, having economic value ("time is money") as well as personal value, due to an awareness of the limited time in each day and in human life spans.
Hello all,
I'm looking for an adult course to do the NVQ2 C&G around my current job. Has anyone used or can recommend training providers in my area (North Herts/South Cambdrigeshire) where I can do the course part time? Ideally somewhere that has other adults - I'm 38 and career changing from...
Hi all
For various reasons, we haven't used the hot water system in our house for a couple of years. It's a vented system with a tank in the loft.
I want to try it out now but wonder whether there could be any potential problems from Legionella or anything else potentially nasty?
I don't...
I've just moved into a property with a Powermax HE boiler, and it only seems to produce one showers worth of hot water at a time. I then have to boost it for an hour before we can get another shower.
The hot water is set to come on from 13:00 to 17:00 every day.
Its controlled by a Hive system...
Hello all, i am doing work for a customer who has asked me what the reheat time of a 250 litre cylinder is. To be honest after all the years of doing plumbing this is a question that i have never been asked before because usually if you need a hot water cylinder then it is what it is, you just...

Hi guys, I wanted to ask , im I right in saying that there needs to be one radiator that needs to stay on all the time, well in my case its the radiator in the hallway, however the installer ended up putting something like a non thermostat valve control which i can turn down or close it fully...
My 50 gal electric WH has water coming up out of this hole in the top. It just fills to the top and slowly runs out over the side. What can cause this and is it time for a new WH?

Hi all
I own a Grundfos Sololift 2 and today today the macerator has been behaving odd. It seems to run for a long time (at least a minute) to flush the waste after I used the toilet. Also it has become very sensitive and even turns on more often when I run the tap. I'm wondering if you guys...

Hi all,
I am replacing a basin tap and managed to remove the one one and secure the new one on place with no issues. I then came to connecting the incoming supplies and seem to have incompatible fittings:
Both threads are of identical size and I'm sure there must be an adaptor which can...

Hi All,
On my Vaillant thermostat, I have set a timer for my heating to come on daily between 06:30-08:30. I was skipping through the options and noticed timings have been set in the circulation pump time programme by the previous owner (see pic). They have set this for Wed-Fri between...
Hi,
I had an Atag system (heat only) boiler fitted about 3 years ago. It’s model IR24 LPG.
It’s worked fine for the first year or so, but on the second winter (last winter) it had a strange problem where it would only cycle on for about 1 minute and then would go off for about 5 minutes, before...
