Bought this heater on May 2018 by the plumber for a new house, moved in January 2019 when I noticed that the heater has a problem.
If you need to have a shower ask all the house occupants not to use the water in the house, otherways you will have a cold water shower.
called Reece for assistance, and the advice was to stop using the water in the house while anyone having a shower.
Now I have to buy a new hot water system because Reece says they can't help.
Purchased in May 2018 for $1,141.05.
Installed this unit on recommendation of plumber who is a good man but obviously there is some sort of heavy promotion or leverage to get this happening. Have not had one shower in five months that hasnt gone cold at some point. Using flick mixer have to turn water to full hot wait two minutes then mix cold in and hope I can wash the shampoo out of my eyes without going cold again. My wife is ready to pull the fing thing off the wall and throw it on the plumbers front lawn. At 55 years old can honestly say worst purchase of my life!
