Running co-ax

It's another Left mind. Mired in its own bullshit

At what temperature would a pipe radiate UV?

I detect a sense of frustration building...

But you know what you're talking about, so what do you know? ;)

Tim+ explained :

That range of temperature would require there to be four failures..

1. The room or cylinder stat to jam in demand.
2. The boilers flow sensor to fail.
3. The boilers over-temperature trip to fail.
4. The PRV to be jammed closed.

Richard formulated the question :

Which is completely understandable :-)

Or the motorised valve controlled by it to stick open

But don't worry, every action has an equal and opposite one, you would inevitably win the Euro millions lottery the next week.

The Sun radiates UV and its surface temperature is 6000C. That help?

dplay, UKTVplay, Pluto (40 odd channels), YouTube (already get that on computer but it is on the big screen), ITV hub (ITV1,ITV2 etc ) iPlayer (BBC),lots of movie streaming channels etc etc . There are lots of channels and streaming services you can download and run (OK some are a bit complicated to install but there are MANY YT guides on doing this). I didn't realise just how much is for free (well freeish it may well be ad supported) I would recommend Fire stick to anyone. Mind you having said all that am watching less and less TV, would ditch it entirely if it didn't keep my son occupied.

A comprehensive,but not exhaustive, list of availlable channels.

IIRC black body radiation is a skewed bell curve, so all surfaces above absolute zero radiate UV. Just infinitesimal amounts. Until you get to white heat and above.

Google 'Plancks Law'.

Thanks all.

To answer some questions .

The Co-Ax at the moment is NOT touching the pipes but it does run in some cavities that have pipe runs in them .

I was asking about POTENTIAL contact.

Thinking about it the boiler only runs at 60 or so so there should be no way that(round Co-Ax touching [not wrapped around] round hot water pipes whose surface should be below this 60) is a problem.

Thanks - off to Amazon to find a thermometer with a bigger dial ;-)

Pipes should be lagged with er - pvc? foam sheathing, anyway.

Cruise control on my van can be set to 155MPH.

Never managed to get it to go faster than 110MPH no matter how much I try :-).

At least three contributors to this thread have explained how this gauge *could" be attached to pipes which contained liquid at 120C. While a fellow scientist of yours has kindly confirmed that "radiated" is indeed correct

You can't really make a general point by cherry picking two examples.

Oh, please.

"In March 2010, an international panel of 41 scientists reviewed 20 years of scientific literature and endorsed the asteroid hypothesis, specifically the Chicxulub impact, as the cause of the extinction, ruling out other theories such as massive volcanism. They had determined that a 10-to-15-kilometer (6 to 9 mi) asteroid hurtled into Earth at Chicxulub on Mexico's Yucatán Peninsula. The collision would have released the same energy as 100 teratonnes of TNT (420 zettajoules)?more than a billion times the energy of the atomic bombings of Hiroshima and Nagasaki." - wiki
