Which is better? Joven or Panasonic. Dont need pump version.

im guessing both are the same, just the design different.

From my personal experience after using Joven and Panasonic instant heaters, I find that the Joven heaters produces hotter water compared to Panasonic.

Just wondering, if water pressure strong like house with external pump, instant shower water hot enough ah?

It will. And usually you have to turn to the Max., and that is max power usage.

If you check Joven website, it state clearly Max pressure is 3.8 Bar.
Min. Water Pressure 10 kPa (0.1 bar)
Max. Water Pressure 380 kPa (3.8 bar)


Panasonic also have (that is about 3.8 bar too)
Water Pressure Min. 0.1kgf/cm² ~ Max. 3.87kgf/cm²

Thanks for the answer weikee.

at 3.8 bar, or higher, even with max temperature set, you only feel bit warm, you don't get warm water especially on recent rainy season.

Don't play, play.

Than Storage or Solar is better.

Storage can heat up water, switch the power off than take bath.

In real life using, I don't thing people will switch it off than take a bath.

Even most of the solar heater now come with a heater element in it for backup.

During thunderstorm, i do. And always advice my wife to heat it, and switch it off. You never know what lighting can do.

You can get a surge protector to protect at the heater wire connector side or the breaker side.

Something like this.

Some spike still pass through. nothing is 100% lighting protection proof.

not sure which is better but im using the joven 1.. so far (7 years) no problem at all

Common practice is not to take bath during lighting / thunderstorm. But sometime is hard to practice when we have baby / kids. Especially when they vomit.

Don't worry too much about all this zap thing. You going to paranoid.

Get the reliable brand and just use it.
