I'm looking for a kettle or a dispenser that can keep or warm up the water around 100 F. The hope is to drink the warm water directly. All the devices I've found so far are made for boiling the water for making Tea, etc. I could get a dispenser, mix hot and cold water. However, I'd need to be careful every single time to mix them in the right proportion; just hoping to avoid any risk.
I was hoping to find a make-human-lazy sort of tool for this but didn't succeed. Thanks for all the answers. I'm going to use the good old stove for warming up and a vacuum flask to store them. I might consider something like this in the future - https://www.amazon.com/dp/B01N4WYPDX?ref_=pe_623860_70668690 .
