hi I don't want to p-ss on your fireworks mate BUT at that temp you will
break windows I know we have 3 times now and its not funny trying
to explain to the custys may be 40 deg   and 20 in winter which is what
 we use for the last 3 years but still windows let go and crack even now
probably cracked 50 ish windows bit here bit there but still a crack so
beware sorry to go on Edd

Edd,


the 50 ish windows you've cracked.... were they mainly small, single paned, set in wooden frames held in with putty? That's the ones I hear pinging sometimes in the winter when it's very cold outside and I've had my water a bit too hot for my liking.

The way the weather is at the moment Hot water is hardly worth the expense.

Wrong! this time of year, the water can dry too quick and cause spotting, hot water system will help on hot glass because equal heat exchange

You`ve been listening to Reuben to much,buy 1 in winter cos it`s cold and by 1 in summer for your above reason,old Reuben must have blisters on his hands from rubbing them to much lol.

Lol   he did show me on one of his road shows!

I don't listen to numptys

Nathanael... Can i ask you how much (Total) it cost you to set up your hot system..

you will learn the hard way it looks like just let me know ....and be honest the first
double glazed unit you break IT WILL SHOCK YOU so be prepared

one window we broke was a perfectly fitted upstairs unit then BANG !! oh sh.. we said
still payed the £60 to repair it then had a word with the glazier  and he said that when it
was fitted it was packed to tight in the frame and the heated water must have expanded
the glass enough to make it break and break it did that wae only one story of double glazed

I've had Hot WFP for 5 months now,... not a single broken/cracked window. I just keep the temp at about 40 Degrees Celsius,.. works for me!

one of my hot wfp customers had a double glazed large pane of glass shatter into tiny pieces which I clean using hot but luckily for me it happened when I wasn't there. The customer said it was badly fitted and just went, but it was fitted 6 months previously and went on a hot day in the spring.

During cold spells I place the brush in the centre of large panes of glass to disperse the heat equally to the edges to minimise the glass cracking. Do you start in the centre or at the top on large panes of glass?

I personally think thermal shock weakens glass and in time it is possible to give, but that's just my theory. I'd like someone to prove it to put uncertainty out of my head.

Not a lot is known about how hot continuous water being rinsed over glass affects it. I would like to understand more if anyone knows?

take a glass - freeze it then immerse it in a bucket of hot water - thermal shock.

I can understand the glass cracking in a small bucket of hot water. Would it still crack in a much larger bucket of water because the cold heat from the glass is being absorbed by a larger quantity of hot water in the much bigger bucket.

I would say yes it would crack imo

its the impact and contracting of the glass that cracks it glass is pourus
