I am having a garage/workshop built about 30m from my house and will
have a water and electricity supply fitted. Rather than pipe hot
water from the house I plan to use an electric water heater.
Do you think a 3kW heater will be enough for this sort of thing?
It depends on "what this sort of thing" actually is.
3kW is not enough to do anything useful to mains cold water on an
instant flow basis, so at 3kW, the water heaters store the water -
different sizes and different capacities. Basically the water lasts
until the store empties, but can be run as fast as you like.
If you wanted to have continuous flow, you would need a type which is
essentially akin to an electric shower and produces a fairly poor flow
rate and requires 8-10kW. Considering the remote location of the
garage and that you will probably want to supply other equipment, this
would entail laying on a substantial supply.
Assuming that you are just thinking about hand washing plus perhaps
the odd bucket of warm water for washing the car, then a storage type
should be OK.

At a previous workplace, we had 3kW instant water heaters for the
wash basin in the toilets, and they were fine for that application.
TLC have a few of these on their web pages. They have something to
make the water feel like it's a stronger flow than it really is,
like a spray head on the TLC ones, or an airated head on the wash
basin ones we had. This is fine for hand washing, but if you are
after large bucklet loads of hot water for some other application,
