I realise there is more chance of being hit by a bus probably but as martinn says we all may as well check to be sure....... a couple of questions regarding this.
My hot water cylinder in my airing cupboard has four pipes coming from it.
1. The first enters the cylinder at the top next to the immersion.
2. I then have one that leaves the left side of the tank where I would describe the 'shoulder' of the tank and loops down through the floor underneath.
3. I then have two pipes, one at the bottom left and on at the bottom right that has a shut off on it.
The one at the bottom left loops up to the loft and the bottom right with the shut off tap loops back downstairs like the 'shoulder' one on the left .
The only one that is cold to touch is the one that goes into the bottom left that has a pipe up to the loft - am I right in thinking this is the pipe that feeds the cylinder with cold water from the header tank and because it is cold everything seems ok?
Can anyone tell me what the other pipes are for as I presume they are simply taking water out of the cylinder to the upstairs/downstairs taps etc and heating system? hence why they are hot to touch and hotter if I run a tap.
I only have basic plumbing knowledge (as far as taps etc go), but central heating is a mystery to me really, a link to somewhere describing exactly how these things work would be very useful on many levels.
As the heating is on this time of year, my electric immersion is off, and hence the boiler is doing all the work. How does this stop heating the water when it gets to temperature? as the immersion is set to 60 but it isnt being used?
