## Customer Reviews

### ⭐⭐⭐⭐⭐ Works very well
*by V***S on 23 July 2020*

Nice piece of kit - easy to install. Note, you are highly likely to need some adaptors - the ones in the box were not suitable. Reaches a reasonable and usable temperature.

### ⭐⭐⭐⭐⭐ Excellent well made product.
*by A***R on 9 September 2021*

Easy to fit and provide plenty of hot water.

### ⭐⭐⭐⭐ total reliability over the past 5 years
*by P***E on 30 March 2015*

We purchased this item in June 2014 and had it fitted by a registered plumber, initially it performed well then seemed to be unable to warm water, so we decided to change it for another heater which turned out to be worse and very short lived. We had this unit reinstalled and had the plumbing sorted, since then the heater has performed well day for the past 5 years, so I take back my previous feedback and would recommend.
