Yes it seems to be quite a good heater. I have only one complaint and thats when the tank temp exceeds the heater setting in Summer an annoying light keeps flashing on the heater.
Cheers... tested the jager this morning in a bucket of cold water it came on and heated the water fine cut out when meant to. It must be the summer heat messing with the tank.. strange coz the weather is crap.
Still fancy a Rena but at least now its not a panic.
