Instant Water Heater, 3000W Tankless Electric Heating Element Energy Efficient Water Heater for in-Line Sinks,Under Sink, and Showers with LCD Display (White) [Energy Class A++]

Bought this 4 months ago and only works with low water pressure and only Luke warm it has now stopped working absolutely rubbish

Brilliant addition to our camper works really well.

It does the trick. Simple 13A UK plug and 1/2" connections. Doesn't try to heat when there's no flow. Has an on/off switch and displays what looks like a reasonable approximation of the output temperature.Always worth doing the maths - I think a lot of people who are disappointed with this kind of thing are expecting a simple replacement for an electric shower. It'll do that (and standard shower hoses are 1/2"), but bear in mind you're looking at a variation on heating a flow of around 2 l/min by around 20 deg C. Worth measuring the shower head output (or seeing what it looks like at 2 l/min), and feeling what a 20 deg rise over supply temperature actually means. Don't open the tap fully and expect a hot shower - it's no substitute for 9kW, but will run off a standard wall plug mains electric supply, which 9kW won't.

Would not recommend. Does not heat water unless pressure is very low and even then it wouldn't fill a mug. Poorly made

Sorry for the delay I didn’t realise there was an option to reviewDidn’t last at all, low water power, blew a fuse without using it

Quality:Heated water to an acceptable standard - other reviews criticising the product don't seem to understand that 3kW is the maximum for any mains device, and will get either a substantial flow of water only slightly warm. With a modest flow from a tap though it gave pleasantly warm water even in the depths of winter.However, it then blew up after 18 months; so not great overall.

I buy this and won't work at all , no hot water, no instructions, no nothing , waste of money and nothing else
