Instant warm water tap for a garage
Discussion
I’m going to fit a sink in my garage shortly. Garage is well and truly detached from the house. It has a mains cold water supply but way too far from the house to plumb a hot water feed. I’d like some warm water up there. Mainly for washing hands and to take the cold edge of buckets of water for washing cars in winter. I don’t need boiling water.
I know I could have a heated water vessel but I don’t really want something that stores hot water. Ideally just something that injects a bit of heat on demand.
I can wire a dedicated high current feed if need be though a 3 pin plug option would be much easier (but maybe too weedy).
Anyone have any suggestions?

I tried a 3 kW tap version for the same purpose and it was useless. It reminds you just how much energy is in hot water.
I then went to one of these:

It’s better but 7 kW is still not amazing. If I want a bucket of moderately hot water I put it on quite a slow speed and it works.

Lowest power electric shower you can find with the hose plumbed into a tap?
We've just installed one of these. As above, a shower unit that heats the water but doesn't store it. https://www.amazon.co.uk/dp/B08C5LGNXJ?ref=ppx_pop...
If you "instant" hot water from a 13A plug, a kettle is the best option.
I've used a basic electric shower to fill a sink quite a few times when the hot water immersion was out of action. It works, but isn't actually that quick, and you'll really need a dedicated 40A supply. Might just get away with a very small electric shower on a decent 32A supply if no other machinery is running. Not sure it would comply with regs though?
For "taking the edge off cold water", a kettle is simplest and cheapest.

You can buy these. They're pretty much exactly the same as an electric shower, but they don't have the dials on the front and the heating is triggered by the flow of water. It gets installed under the sink. You're not supposed to use them with mixer taps, but I do and haven't had a problem (yet)
More power = hotter water / faster flow. More power = thicker wiring and dedicated MCB.
I have a 10KW one in my garage on it's own 40a supply.

The kettle is definitely the cheapest option.
I had one of the electric hand-wash taps in a garage previously, and it was good enough for the job, with warm-to-fairly-hot water, enough to wash hands or a few dishes. They're not for boiling water or filling buckets to the brim in seconds.

One advantage of being 3kW is that the wiring needs are pretty minimal.

Thats similar to the one i used to have in my workshop, was plenty enough for washing hands/bit of warm water in a bucket.I had one of the electric hand-wash taps in a garage previously, and it was good enough for the job, with warm-to-fairly-hot water, enough to wash hands or a few dishes.

You can also get a small water tank, sometimes known as 'calorifier' and heat it from an 'eberspacher type diesel fired heater.
You may see these in the likes of gas board vans at roadworks sometimes. Also boats and caravans.
We were considering this, as we have a diesel heater in the big shed.
