Recommend naman kayo ng water heater that could work on low water pressure..I bought a panasonic multi-point and sadly it didn't work cause of the low water pressure.
Re: Shower water heater that works on low water pressure
Try this, my unit is an AEG BS 35---60E rated at 6KW @220V 60hz. It only needs a flow volume of 1.5 - 2.0 l/m and it's an instantaneous model. Right now it stays w/in the halfway to about 4KW setting and water stays hot all through out it's usage even on a summers day when water pressure is low. I hardly go beyond these settings and my electric bill ain't bad either. I bought mine at the Handyman shop in Robinson's East. They gave me 3-years warranty for parts and service.
