Hot water at any time ....

Is used here in the kitchen of an older house with no hot water preparation. With some basic knowledge easy to assemble. I've hung a switch in between that he actually midweek heated only in the evening for 2 hours, I think saving life and power.
I looked at a lot of different models, this might have been a little cheaper, I would like to say is: Who buys cheap with such devices, buys twice .... (personal experience)
Very well made, all very valuable, one of the best in its class-strong buy recommendation.
