Make a Shop Water Heater out of an old Humidifier

On cold days I really want a warm water source in my shop. I don't need a whole tank full and I don't need it every day. But on cold days it would be nice to wash my hands with warm water, or keep my fingers from freezing when I'm doing wet-sanding or cleaning.

I've used a hot plate, crock-pot, electric kettle and a coffee maker to heat water. They all heat up the water and it's nice to have a pot of warm water to dip things in. But I always found them inconvenient because there is no dispensing mechanism. I had to pour the hot water into another container, maybe  mix in cool water, then dip the objects or my hands into the water. That's too much trouble, I wanted a hose and spigot so I could just spray down the dust and wash my hands easily.

I finally found a solution when someone donated their broken home humidifier that had a water heater built in. I just added an old spray hose to the humidifier, and now I have warm water whenever I need it.
