Obviously using water in 0 degrees isn't ideal but I'm sure like most of us we offer an all year round service. Using trad you get the conservatory windows etc (unheated or low heat rooms) that freeze over first thing in the morning. To counteract this I've always added a tiny bit of anti freeze to my water to help prevent it, but how do you find WFP during the cold months? Does it freeze on the glass or window sills? I know storing the water in barrels as I do and leaving them in a cold van all night isn't the one (prepared to leave these in my house until I head off in the morning to prevent this) but do you get issues with it freezing in the hose as well? Just something I've been curious about but can't seem to find a decent answer on google. Cheers.
