Under sink heaters - recommendations

When I was first sorting this place I wanted a source of hot water and had a 20l Baby Burco (I don't know why). I fitted it with a ball c*ck and plumbed it in on a washing machine hose with it stood on the draining board.

It worked perfectly for a good few months (all be it a bit lossy but I only put it on when I was round here working).

It all depends how often you are going to want more than 15L of hot water - and training users not to turn the tap on for it to run hot.

Instant ones that are any good are 7kW or more flash boilers and not cheap but they can keep up with demand at peak times.

They are not that great on insulation run continuously allow 50W base load 24/7. The water is still warm the next morning not hot. The problem we found in the VH was that they were OK in the toilets except when you had a event with an interval when the first half dozen or so would be lucky and the rest got to wash their hands in ice cold water.

Likewise in a kitchen except even more so if there is any washing up to do - you can't have another bowl of hot water for at least 15 minutes.
