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.
Every two weeks or so I have to go and top up the system because the hot taps are running cold. Boiler display is flashing 0.6 bar and I fill up to 1.3. I've had an engineer look inside the boiler and he can't see anything wrong. I've checked the pipes all over the house and cannot see any...
Some advice needed please re a 3 year old combi gas boiler. The hot water works but no heating. A gas engineer was already booked to do the annual safety check before the fault developed. He said the boiler is ok with no fault. He said there must be a leak under the floor boards causing hot...

Hello, hoping someone can advise me. My boiler stopped working - no hot water or central heating. Called out a company who came and assessed the problem as being that the hot water element in the immersion tank needed replacing. (I don't know exactly what it is called as the company has still...

Hello,
Newly moved into a house with a mains fed cylinder system. I've never had one before and struggling to get it working.
When I turn either heating or water off at the timing unit, the other works fine. Eg, with heating off, water works and vica versa. The indicator lights are solid blue...
I currently have a Vaillant ecoTEC Plus 438 system boiler which is 13 years old. I have been having problems with the boiler which potentially boils down to the heat exchanger so I am now looking to bite the bullet and have a new boiler installed.
My set up at home is that I have a 4-bed...

What would be the heating time for this (indirect) vented cylinder? Rated coil = 14kw
Is it 96 litres x 4.2 specific weight x 40 (dT) ? How do I calculate the heating requirement of the boiler to heat this cylinder.
Secondly, they are simpler to install as opposed to unvented type but what are...
I wonder can anyone give me some advice over what has become a very annoying situation?
Approximately three months ago, what I assume to be water hammer started in the airing cupboard of my second floor flat. This manifested, and continues to do so, as a repeated, i.e. every 60 seconds or so...

I have two thermostats which control a demand valve each which when opened kick the boiler and the...

I keep getting this message every time I reply to a post.
The only way round it is to use 'snip and sketch' and post my reply as an attached file (like below).
Any solutions?
Hi everyone,

My Ideal boiler pressure gauge pointer shows about 0.85 when cold (about 1.8 when the heating is on).
10 weeks ago the readings were 1.0 when cold and 2.0 when hot.
Clearly there is a loss in pressure over time. I can see no leak on any radiator or near the boiler. Is this pressure drop of...
Hi,
Please can anybody help with why my CH system does not produce enough hot water when the boiler is required at the same time to provide heat to the underfloor heating? More details here :
1. If the CH is programmed to just provide HW then running it for an hour in the morning produces plenty...
