Title: Hot versus cold WFP
Post by: Wayne Thomas on November 14, 2007, 08:16:54 pm
I always use warm to hot water for WFP but today I had to use very cold water.

I still maintained my fast speed for cleaning the windows, but today I got my first complaint in years because I hadn't shifted some bird poo completely from 2 windows which wasn't visible from ground level until I inspected the windows from inside the property. It knocked my confidence a bit so I had to spend longer scrubbing the windows at a slower pace this afternoon to be on the safe side. Also, my minibore hose became very stiff and kinked like mad which made it harder to reel back in on my hosereel.

If I had been using hot water for cleaning these windows I definitely wouldn't have had any complaints IMO as hot water sheets quickly like very thin treacle where as cold water just sheets thickly and slowly.

Does any other hot WFP users notice the differences between using hot or cold water and if so what are the differences?

I am aware of it and will continue to use hot rather than cold water as it's definitely better for cleaning and much quicker especially when it's freezing. There is no way I will go back to using cold WFP after using hot WFP regardless of whatever Aquafactors say about hot water changing the alkaline/acidic content of water after it has passed through D.I. resin.

Wayne ;)
yes, yes, and yes- but I think it's counter productive to go into details. Just let them all carry on. ;)
Show me the money ;D

The 'article' referred to is in fact a paid for bit of editorial from some chancers putting forward the benefits of some kind of detergent because it is less agressive.

As far as i'm concerned the fewer of us in the know the better wayne.

I have not used hot myself, have seen it done though, and my result was better with cold. I am not knocking hot in anyway and would never say I would not go down this route in future, but you say you will continue regardless is not a wise move if it does damage frames etc only time will tell if this is true or not, if it is the Hot users are in for a very big suing spree from customers. In the mean time I will look into it alot more, I prefer to do my homework before taking on something new, as the people that sell it are after one thing that is money. I would love to see if they have a disclaimer on the hot system, from what I see they do not.

It is obvious that hot will clean better than cold for the first clean and maybe the odd bit off bird poop, but the extra cost in vloved from where I am sitting is not worth the outlay, if they guarenteed the system for 10 years (about the time it would take to recoup the extra outlay) I may think about it a little harder.

Wayne if it works for you m8, good on ya, not putting you or it down, just saying my thoughts on it, so please dont feel I am having a dig at you.

The running cost and depreciation of water heater equipment is easily forgotten in comparison to the additional work cleaned daily as a result of using hot over cold with the added advantage of knowing that you rarely receive any customer complaints especially cleaning high level windows regardless of weather conditions or state of windows.

Window washers you don't offend me. I like constructive critiscism and have the shell of a rhino for any knockbacks in life and let moans and groans go in one ear and straight out the other :)

I put a couple of posts and read one in particular by Luke. Basicaly the idea of hot was shouted down so why bother trying to convince people.

I agree with every word  you say, and it has made a bigger difference to my work life than George.

cold water is still warmer than frozen glass, if you rinse first it removes frozen particles of ice of the glass, then proceed as normal, if it was below freezing tempratures, i just would not go out to work, the advantage of warm water is the pipes would stay clear, have you cracked any windows using hot water,

The colder the outside air temperature is, the cooler (less warm/less hot) my water for use on the windows is. I haven't cracked any window panes yet but I make sure I know exactly what temperature my water is before I use it. I know V8Edd has cracked a few :)

in very cold weather, there must be a different procedure, than we normaly use the wfp,   i would have thought that you would rinse cold water first, then turn on the  warm water on the glass, this would stop the chances of shocking the glass,

That`s the thing with hot systems,if the waters to hot on a cold morning you`ll crack the glass where`s we would like hot water for not only cleaning but for keeping you working in cold weather.If you can`t have it to hot then only for keeping the hoses freezing what`s the point.

That would take too long and too much fluffing around. Just decide on how cool / warm / hot you want your water according to how cold it is for the morning and increase the temperature as the day's temperature warms the windows up from the sun (even if it is obscured some days throughout the winter). 'Shocking the glass' is what causes panes of glass to crack so obviously you don't want to be using piping hot water on icy cold windows.

you do know if you are talking about domestic houses, they employ you, they cannot make a claim against themselves. same goes if you hut yourself at there property you are there resonsibility (did you know that?)


if it does damage frames etc only time will tell if this is true or not, if it is the Hot users are in for a very big suing spree from customers.


Make your mind up mate!  ;D

Easily overcome. Just don't have the hot water going through any resin. Purify it on the way into the tank. Simple.

This is how the thermopure systems work.

hey niceandclean have you got a thermostat on your system , I have now and regulate the water too 25 degs but today it was -3 all day so the heater was on for 2 hours only just to warm the tank up a bit. One hundred percent agree that it is faster to use warm water and we have not had any complaints in 2 years in fact our trade has gone up by 4 times what we had 2 years ago with extra work and add ons like con roofs 3 /4/5/6 story jobs which wasen`t poss trad ...SO to answer the question was it worth it ....OH YES you bet it was ,who the hell wants to use cold in this wether buuuurrr not us another good selling point which helps us get new custys was them seeing the steam on the windows works every time without fail EDD
ps you can put warm to 60 degs water through the resin as it work with no probs

The simple answers are normally the best, and thats a corker  ;)

Hi v8edd

Where did you get your thermostat? Just what I need. Our systems are still full on heat. Only option I have is to preheat the tank which takes a while.

any plumbing shop we used an underfloor heating unit about £30 if you look where the grey pipe joins
 the blue I took a cold feed from the blue and an hot feed from the grey the thermostat  mixes what temp
you need and then goes to the temp gauge and then the hose reel
Its a bit untidy but hey it works one day Ill tidy it up!!!

I'm not on anything ::) and not being clever,  merely pointing out what you believe to be the difference in attitude over possible claims. and which may be of interest to other members here.

You say: If the WC  damages any customers property it is his fault, he is liable  and I agree.

You also say: That if a WC injures himself on a customers property it is the customers responsibilty, the customer is liable  and can be sued by the WC?

As far as I am aware that is correct as they are employing you.

It's not quite that straightforward.  There is a degree of liability and accountability on the client's part, particularly if you are put in a situation of risk on the client's property and the client hasn't pointed out that risk or made it safe for you...etc
