Best Under Sink Water Heater

My hunt for the best under sink water heater began when taking my kids to saturday league football games. We’ve all had it. All wrapped up for sub zero degree temperature and you pop into a cubicle to wash your hands. That’s precisely when you’ll wish for some warm water when you open the taps.

Or when you are at a camping site with the kids and they need to pop to the loo – as they do – for the millionth time. You’ll want to know for sure that they at least have the option of using warm water or cold water to wash their hands when required to.

So my hunt for a sturdy, heavy-duty, compact water heating solution began. I eventually bought the Redring under sink water heater for the boys at Saturday football. In my research however I found all the undersink water heating solutions below which proved to be the pick of the bunch.
