Ariston Andris Lux 3kW 15Ltr Undersink Water Heater is rated 4.4 out of 5 by 8.
Rated 5 out of 5 by from Ariston water heater Excellent product. Replaced copper hot water cylinder with this much smarter and smaller unit. Airing cupboard now am actual cupboard. Very easy easy to fit and saves on power. All of the previous reviews are correct however, make sure you also buy some fibre washers to connect to the unit.

Rated 3 out of 5 by from Budget water heater Not bad for the money, fitted quite a few and only had a problem with one. (Screwfix exchanged no prob). Bad points ; no re settable over heat stat, and water connections are not great, seem to be designed with flexi's in mind which I hate , would prefer a compression fitting or just a plain 15mm pipe.

Rated 5 out of 5 by from Good bit of kit Have various workshops with only power and water, so these are ideal for supplying small amounts of hot water. Used various 1kw instant water heaters but have to limit flow so much takes ages to fill a small bowl. Will replace them with these.

Rated 5 out of 5 by from Water Heater Last year I purchase about twenty other type of water heaters which are letting me down all the time, I have now started changing them for this type and what a much better unit, not a days trouble since they where installed. not like other type where I was get callouts to repair every other week. These unit are spot on and trouble free.. wish I have installed them to start with.

Rated 5 out of 5 by from a great buy but check fittings I bought this rather than replacing the ancient copper cylinder/header tank after removing the bath in favour of an electric shower meaning there were only basins in the house. Very easy to install on an outside wall (cold water feed Ts off to a blowout valve that goes through the wall) so just cold in, hot out. As per previous reviewer's comments - the plastic inlet and outlet fittings leaked badly and we needed fibre washers and ptfe to seal them. Open the box in the shop, the plastic fittings are easily accessible and find fittings that will seal - we tried several before finding ones that worked - and then needed fibre washers as well. There is one knob to set the temperature so easy to use.

Rated 4 out of 5 by from Great little heater Great heater, easy to install and doesn't need a lot of space. One problem is the plastic fittings could do with the thread being loger as you can't tighten the femal iron enough which then leaks.

Rated 4 out of 5 by from Very good unit Have used lots of these in the past, very reliable unit. My only critism is that the plastic fittings need lots of ptfe and a fibre washer or they will leak., but if you do this you will have no problems
