hi mathew, when cleaning single glazing in cold weather do not use hot water it will crack glass,
use warm water if you can, with mine i can use the cold flow, but with the heater on.
as i am not using the hot flow, the hot water goes back into the tank, slowly  heating
the main tank of water, this gives me warm water. Never use hot on frosty mornings on single glazing,
