I'm not trying to convince anybody that they would be better off using a hot WFP system over a cold WFP system, it's up to the individual if they think paying the extra money for the hot system is worth it. They also have to take into account the running costs, i.e. diesel or gas or whatever.
I wouldn't waste my money using a hot system if I couldn't clean windows quicker which saves time and increases my earnings.
The advantages I have found:
Hot water dries on glass quicker, so when the weather is bad, the water left on the glass dries quicker than cold, so less chance of collecting dust, sand,etc and low TDS rainwater.
Hot water shifts stubborn marks and breezes through initial cleans much simpler with less effort.
Customers can see the de-ionised water drying quickly which results in fewer complaints from awkward moaning customers who are at home whilst the window cleaning is being carried out who dislike WFP method.
Hot water softens the hose, keeping it supple instead of hard which enables the hose to be reeled in much simpler with fewer kinks, especially in the winter.
Hot water on large hot panes of glass in the summer dry better than cold water on large, hot panes of glass.
Able to work early on very cold mornings problem and stress free when cold WFP users are moaning that their hose, etc are all frozen. Last November I was working in minus 5 early in the morning without any hassles. No need to take everything out of the van on very cold nights just to put it all back in the van first thing in the morning.
One other reason I use hot WFP rather than cold is because I suffer from chronic arthritus so I want to make life as easy as possible for myself.
Hot WFP gets slagged by many, that's up to them, it's their decision and I respect that. I've made my choice and I wouldn't go back to cold WFP regardless of what people have to say about it.
