brought new panasonic DH-3RP1MK water heater recently and having problem with the pump, as the pump keep operating non stop even there is no water flow. reply from their technician is that this model and other similar model which below rm600 are a failure design, whereby model above rm600 are improved from this failure design. i hope ppl who reading this comment can browse yotube as there are many pl post video on the youtube. pls dont waste money on panasonic water heater unless u buy above rm600.

White, 4800W, DC Pump / DH4HP1M
The 4800W pump ones list at above 600

as told by their technician those above 600, i bought mine with budget so not really survey those over my budget.

but then the quality of the unit will drop if price <600
   

any recommendations for water heater with DC pump priced around rm450-600? I wanted the panasonic DH-3NDP1 earlier but comments in this thread mostly give bad reviews.

Prefer a slim and stylish metallic color.

no control on pump power means that the water pressure is too strong and cant be adjusted lower? actually my condo i feel the water pressure is good, just feel wasted if i get a normal heater and turns out it cant work.

smart revo almost rm1k
thanks, this is around rm450 right?

typically condo will not have pressure problem, only landed? i live on 28th floor of a 38 floor building.

4.8kW one cannot use with typical default 2.5mm² cable (redline 21A) . Really running redline of the cable because rated load current already 20.87A .and that 21A redline is based on quality cables. Running at redline for prolonged period is dangerous.

If you want to use this model you need to make sure whole wiring setup is 4mm² good quality cable all the way from DB box to the water heater (stuff from mega kabel, caramay, tonn, fajar cable) which typically won't be installed by developer.. you need at least 4mm² cables which have higher redline of 32A.

Hi all, would just like to check if anyone have encountered this issue before. I have Panasonic DH-3NP2MS water heater installed in my new home. Yesterday when I troed to use the water heater, the water came out intermittently and gradually decreases until there is no water, and the pump sounds extremely noisy.

I have checked for leaks in my piping, but couldnt find any. Appreciate if anyone can assist in troubleshooting the issue.

Hi, I just bought the Panasonic 3MP1 and would like to understand more on the pump operation. When I turn on the switch, but my water is not running, will the pump still be running?

My incoming pressure is actually very strong, so will this damage my inlet pipe due to build up pressure when I turn on the switch but not using the water?

the pressure is strong before i install the heater. Then the installation of the heater uses a 1.5cm diameter metal rod for the water inlet and outlet, which I think makes the pressure to be greater. Adding with the pump function, my outlet connection is leaking with water even when i adjust the inlet at the WH to the smallest.
