The boring thread.....

[klondike]

Klondy, it might be useful to replace the lock shield with one with a drain off valve.  No huge difference in price, plus it will give another access point for flushing, if ever the need arises.

I did consider that but it is a long way from a door and the room is carpeted so I didn't bother. The only drain point is right by the back patio doors over a tiled floor.

Water seems to flow freely enough from either pipe. The water coming out from the pipes and the rad was all pretty clean and the rad refilled OK. There was no fault with the lockshield itself which is pretty much what I expected. I bumped the thermostat up and had a play and I'm now thinking it may be paired on a long run of 10mm pipe with the rad next to the boiler which is on 15mm copper. I've tightened the lockshield on that one well down to restrict the flow and maybe balance the two but when I turned it right off yesterday it didn't help so I'm not overly hopeful and still puzzled,

I'll check what happens when the temperature drops enough for it to start up again.

Mystery indeed.  Thermostatic valves have made the use of lock shields to balance the system obsolete.  The old requirement of having a permanently on radiator close-ish to the boiler is also no longer needed due to internal by-pass valves.

 Maybe whoever installed the rad attached via teeing off from a single pipe rather than by cutting into the flow and return ones🤷🏻�♂️. That would explain a "reluctance" of water to flow through it and instead to follow the path of least resistance.

Either way, it's a PITA.

No, he just likes big burly men.  He's never fully got over his time in the barracks 😬

Dear oh dear,  this thread must now be subject to the 9o'clock watershed surely, it's  become Most Unsuitable for youngsters and those of us of a delicate nature....🤯

[Mups]

You are quite right, Ruthio.
It  makes us delicate damsels so embarrassed doesn't it.

In fact I have needed my smelling salts twice!

From what I hear, you have a cruet set with one pot being full of smelling salts to help guests recover from eating that unbearable swill you serve up.

On a totally unrelated point, ...what happened to Judd?  Not heard from him for a while?🤷🏻�♂️

[Mups]

Regarding Judd,  he had a few health problems a while back,  but I believe he is on the mend again.

Strangely,  I was thinking about him today, too, Dex.
I will drop him a line over the weekend and see if he's alright.

[Mups]

Oh well,  off to beddy-byes now.   I have had more than enough excitement for one day.
It's supposed to be wild, wet and windy over the next couple of days. 

Good night all.  Sleep tight.   

[dextrous63]

Send him my kindest regards too Mups.  I miss his humour, ... just so clever.😊

No. One is definitely hotter plus at the distance there would be no flow at all if both sides went to just one pipe. It does seem to run hotter now too. I'm sure it used to work just fine and after the first glitch continued to do so til the other day when it played up again. I'll still add the new rad in the summer as it always seems to go wrong when needed most.

You'd think so, but single pipe heating systems were once not so uncommon as one might imagine.  My current house being a case in point.

In fact, this is one way that large houses/hotels etc have hot water supplied so quickly to taps, ie by constantly running hot water around a single loop with localised T's into it.  Not heat efficient maybe, but the only obvious way of not having to wait for ages for hot water to get to an outlet from a boiler/heated tank placed a long distance away.

Single pipe heating systems just added a return T to the same pipe.

As I was just thinking, there are different bore sizes in different water pipes.  The old 1/2" copper pipe is different to the modern 15mm pipe, as anyone who has ever tried to join these two sizes together will attest to...
