I'm seeking some advice on choice of electric, undersink boiler.
I only have a need for hot water, Maybe 4 washing up bowls a day, 8
washhand basins full per day ( unless the water from the boiler is
drinkable and then 8 kettles full per day too).
Can anyone recommend a small undersink boiler that will be suitable
for this?
Also, would the smaller type of electric boilers have a plug-in rather
than a hard wired option?

How much water do you need for a washing up bowl? 5 litres, 10 litres?

A 3kw instantaneous water heater only delivers around 1 litre of hand
hot water per minute. So, it will take you 5-10 minutes to fill the
washing up bowl. Are you okay with that?

That's for water coming in at 5C, and washing up water at 50C.
