Review: total reliability over the past 5 years - 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.
Review: Rubbish avoid - Absolute awful product, fitting this has resulted in me losing lots of money. Extremely poor flow rate and the temperature can not even be described as warm. Technical help line are as useless as the product also

Good unit, not as warm as I imagened but warm enough to wash hands. You do have to turn the water pressure down quite a lot to get the warm water. Easy to install. Good product
