Have you evidence of bees preference for warm water?

This picture is from beginning of march. I poor every day warm water at the beginning of the morning flight and they prefer it rather than cold one. I place the water jars in early spring. Usually when I want to they get the habit of using this water source I have to poor some sugar syrup in it to attract them at the beginning. But when I put warm water no need for the syrup.
This I will repeat again in the spring. Cause at least I believe it increase the speed of water taking, also I believe that spare the bees rather than taking ice cold water. After all who doesn't like warm tea in a cold day..

thanks Goran,
there have been experiments with the sugar content of nectar and how bees will favour high sugar content at a greater distance rather than weaker and nearer and communicate its prescence to other foragers.

Perhaps the same behaviour is present with regard to water termperature.
if so then at least we can have more successful tactics to divert bees from hot tubs

I have only anecdotal evidence. A trough under a tree was ignored until I moved it one foot into the sun. As soon as I did this it was heavily used.
Was it warmer water or warmer air? I think the air/light level more than the water temp.

that would need a careful experiment to sift air light water temp.. I think i will stick to the physics at the moment

I have a hot tub along with 5 colonies. They are obsessed with the hot tub and often drown. They have two ponds next door to the hives. So they do prefer the hot tub water and it must be the chemicals as the water that splashes around the lid is cold by the time they go for it. It must be an attraction to Bromine

Must make using the hot tub interesting!

We have a number of water sources near our hives and the bees preferred the one in the sun. Once they chose it they stayed using it throughout the season. It was the yellow lid of a bin, by the way, approx 3' off the ground.
