Water was about 45c at the brush, window was a side window above a flat roof.
It didn't crack whilst I was cleaning it, literally I'd walked away, put one foot 0n the ladder and heard a massive pop!
Customer was cool about it, just waiting for a glazier to get back to me with a price, still a shock though. Only been using hot for around 6 weeks and didn't think I'd get water hot enough with an immersion to crack panes!

I thought 45c was cold compared to NWH and dazmonds standards!

Just had a quote of £144 to change the glass, does that seem reasonable or shall I shop around??

Maybe the window was already stressed from a warped frame or some such, or maybe it had a micro crack in it, and 45 degree water was just enough to finish it off.  It doesn't take much to break a window once it is weakened.

Not too bad, I was £130 for a similar one.

The way it popped some 10 secs after I'd finished cleaning it suggests to me it was packed too tightly in the frame and couldn't expand so cracked with pressure.
Iv cleaned thousands of windows since having the system installed and that's the first one to pop. Guess it was bound to happen sooner or later.

Yeah I one similar last year 130 notes she was fine long-standing customer,remember it’s all about the glass itself if it has any defects in it pop she’ll go.
That’s why you can go for months without a problem but once you come across glass even with a hairline crack it will go from corner to corner,mines on minimum still as I have the hottest system in the country 🤣🤣🤣 mind you I lose 60 degrees on the ground this time of year eh Daz 💩

Supply and fit. Rang a few companies and prices were all from £140 to £190. The white georgian bars in the unit make it slightly more expensive then a standard unit.
All were a bit shocked that the window cracked with 45c water on a fairly mild day. The general consensus was that it was poorly fitted.

Too much simspons? You need to get out more, maybe visit a gime when they reopen.

45 degrees is easily hot enough if the glass has a crack in it the pane I cracked was a UPVC unit I’d cleaned these windows a couple of times before and hadn’t noticed any defects from the inside,that’s the thing on cheap windows the finishing is awful from the factory but you won’t see it as it’s hidden behind the beading that clips over the edge of the glass.
This finishing I’m talking about is when the 2 panes of glass are sealed together with a rubber product at the factory,last year I did one like on this thread and a top opener both windows were a cheap product I can’t remember cracking glass in top of the range windows,the only other obvious ones that will go easily are single glazed windows that are fitted tight with no flex due to putty or tacks.

I'm sorry but at £140 they're having your pants down.

That glass is about £40-£60 supply.

I had to replace a thermal bi fold piece of glass and it was £220 fitted!

Windows that size we pay around £60 - £100 fitted (max) Most are around £60-£75 fitted.

In the last 5 years we've replaced about 6 windows all down to goodwill.

It was defo poorly fitted.....it had no room to expand thats why its cracked like that....

I've cracked 3 panes now but not had to pay for new glass as all 3  had a slight crack in them anyway...the hot water just made them go right across the glass and the customers were fine about them....

I am wary though now...if the glass has even the slightest crack in it I wont clean them with my hot water....

[zesty]

You lads aren’t selling hot water very well!

[windowswashed]

45 degrees ain't hot. reckon the glass was packed too tight on a normal spring day shouldn't happen

I thought it was expensive but 5 different quotes all £140 plus. I sent them all a pic of the crack and they all said its a bit more expensive because of the internal Georgian bars.

[NWH]

To supply and fit I paid 130 very similar size to this.

That’s not normal heat crack   That’s been packed to tight a normal heat crack is usually just one crack , we use water 60-70 degrees in very low temperatures and have only ever cracked 3 pains , one was packed to tight and the other 2 had existing chips under the glassing strip that was only apparent when the glass was replaced . That  price sounds very expensive to me  I paid around £65 for  a similar size pain . I doubt the water temperature you were using was the cause , it would have gone bang one day just unlucky you had just cleaned it .
