Hi all,
i have tried to search this topic and found discussion around 2014 thats not really up to date to current technology. Maybe...
So i would like to aks all sifus, whats is the good brand that able to heat up water faster for storage type heater within 25 liter to 30 liter.
i found JOVEN and HYDRO ONE heater quite famous but its just my opinion.
Anyone here have experienced with small water storage to have faster heat up process.

I know the best heat up for sure from instant heater, but i found instant heater not giving good appearance in the bathroom compared to storage tank that able to hide on the roof. 

Thanks
