hi sifu here
in terms of safety
which one you will keen to have？

what's with inverters installed into water heaters. do they actually work because I know we do not take three hours of shower to stabilize it

Looking for water heater with good safety feature like Live ELCB testing. Pls share your reviews.

I cannot find a good point to put an inverter in the heater.

exactly. kinda stupid. I was quoted 800 for the alpha i8 water heater. think I'll just get the standard one. I read water heaters with pumps break down easily

Inverter in water heater? Is it on the pump? Dumb to use inverter on heat element

Not really. Last very long.

I throw the water heater because of age. (Risk of shock). Not even wan is spoil.

The pump is adjustable by the consumer. And pretty useless as mostly the pump have to set at max to run. Since it not really powerfull.

All my Instant water heater with build in pump won't last > 4 years. While the one without pump still going strong.

ic... useless feature to make customer pay more

Never 1 is spoil. Average use is 6-8yrs.

Now using Rinnai for 3yrs liau.

think I'll just get the alpha i8 standard without a pump and inverter but add in the rain shower head

Why not think about storage type water heater?

If the pressure is good enough, you don't need pump.

If you using for rain shower head, the water temperature will be lower compare hand shower head. Cause of the water droplet cool down effect and the volume flow.

Panasonic is a bigger brand and maybe more expensive.
But one thing good about panasonic is the One Push On/Off switch.... something different from others water heater

if for condo, do we need pump for the water heater?

Anyone uses gas water heater?
