I can`t show you a picture at the moment as this site won`t let me it say`s the upload folder is full or something contact admin,i turn mine on in the morning 15mins prior to work and it stays on till i finish work.Hot water window cleaning is 100% better than cold not just my opinion,with installation mine cost me 3k and it was worth all of that.Once you try hot water you`ll never go back to cold believe me,my system has no pipes to drain and is designed to be used for our job unlike DIY types i`ve used and some still do use.
