heater should have a flow meter, cause its a protection thinggy..

flow < rated = heater off..

pump should be always pumping unless u stop/set it to off right ?

thanks guys! actually i was asking cause i might have made a error on my piping design

i put a control valve at the outlet all cemented up now and tiled

i cant use instant heater now with pump. :sad: scared the pump explode

joven one was done i think by lyn user called leeyeung or something like that.. its in the joven thread...

one thing is sound of the dc motor the other is how powerful the pump is..

Thanks guys, i feel sad now. No pics, but this is my design. I worried:
1) Water sensor will keep getting hotter if faulty if both my outlet valve are closed
2) Water pump will continue trying to pump if both my outlet valve are closed
Now i have to at most only do instant heater with no pump. all the inside piping already completed and tiled over liao! 2 toilets like this style!

SIFU helpp!!!!   

I'm also in dilemma in between to buy Alpha Smart 18i with rain shower or Joven with Cabana rain shower.Saw the youtube,seem like Joven pump is very noisy.No idea about the Alpha one.Any good samaritan willing to share us the video for us to compare?Is Alpha brand reliable?What is the price now?
