hot i use l5 boller

But does hot water not freeze quicker than cold?...even hot water systems are not a complete magic wand to 'beat' a freeze.

When it is very cold...sometimes it's just better to call it a day and put the fire on and watch some cartoons.

Attached are a couple of pictures I took this past winter of 10% mixes of water and methanol which once on the glass started to freeze at about -7..another point to note is that the spray off water that is in the air...seemed to get on my face and make it sore...

Cheers

sorry pingu but you're wrong to an extent , last winter i only had water freeze twice once on a porch and once on conservatory always the coldest places on house as most don't have heating in them hose froze when laid in deep snow when pumped was switched off only lost one days work last winter -7 allday ISOPROPANOL WORKS check other forums

I am ok with poles and water in containers keeping warm, as I have a outside boiler in out house they can go in there. But my worry is when on real real cold mornings, water freezing peoples windows up etc.... Barry

Mostly this is resolved by starting later when the temperature has climbed a bit.  However, last January/February there were times that it stayed below freezing all day so I lost work time.
I bring anything vulnerable into the flat such as poles/brushes/reels and I run air through my van system by removing the feed pipe from the tank (no RO in van) so that the pipes and pump are empty.  Even if there is a trickle left in there, at least it allows room for expansion if the little bit left does ice up.

Pro...the amounts that you have quoted simply cannot work...it's has nothing to do with my opinion and everything to do with physics...I am not trying to start an argument with you and I'll agree to disagree but 25ml in 25l in minus 5...it does not compute..it is just far too little an amount to make any difference.

There is a difference between when temps drop for short periods of time and when sub 0 temps continue over a period of time...which is what occured here in mainland Europe with one particular area in The Netherlands experiancing -20 as an overnight temp an regular day temps of -4 to -7.

Remember the temps that I had here in Holland over a 21 day period were sufficient to freeze a 500l tank in my garden solid....in order to get my pump out I had to free it with a sledghammer....and that was a week after when the temps were above freezing.

I will not pursue this thread any further but suffice to say..physics will prove the numbers.

Even a hot system will not guarantee you can continue work in sub zero temps,.. though it is a real big help!

My personal approach is:
IPA helps very little against freezing, BUT it does increase cleaning power imo which is handy on the very cold days when my heater is turned down to minimum cause I don't want to crack the glass.

I always carry salt (25kg bags) in the van and sprinkle footpaths before I start work. I don't want to be blamed/sued if someone slips on ice. This slows down the work, but it has to be done.

My van is insulated, and I put an electric heater in there overnight when the temp is going to drop below zero.

My RO and static tank are in the garden at the moment, but they will be moved into the shed and insulated before the winter. Perhaps a 2nd heater in the shed too,..

no prob's pingu dont want cause ill feeling i canonly go off other info and my own experiences
