We recently did up a building used for seasonal staff accom,

 

We removed a 25L cylinder in the kitchen and fitted, a variation of the instaboil that has some retained insulated  storage, 2-5L

 

So basically its mini undersink version of the 25L cylinder,

 

However due to water expansion when heating it required a special tap to vent an excees expansion.

 

Is it tempered to 55C, or does it come out fully hot?
