Hi guys, I am currently installed Water pump(CNP 0.75HP, Max pressure: 10Bar) the water flow is very fast and feel like waterfall
the thing right now, I was looking for water heater with Rain Shower

when I look around at shopee, mostly Rain shower must come with Jet Pump build inside the Water heater

here why I feel Build in Jet Pump water heater is not good for house that already have strong water pump(or maybe I am wrong?):
1. the water heater build in Jet pump have a blade rotor that spinning very fast to speed up the water flow but, this speed have a limit set by factory
2. if we use Water pump together with Water heater build-in Jetpump.. does it make Waterheater Jetpump decrease the full performance? (bottleneck issue)
3. or the sudden increase water flow tru the waterheater will make jetpump will not last longer?

here is my question:

1. if I using Water pump, can I use Water heater with Jet pump?
2. if I using Water heater without Jet pump, How to purchase set of rainshower and attach it to waterheater that do not have it?
(any reference link or place to buy or installed will be nice)

Since your pump rated at 10 bar you might want to consider checking the bar of the water heater too. Mostly cannot sypport more than 4 bar. I live in an apartment where the pressure is about 6 to 8 bars because i am at the lower floor. It broke some of my water heater.

You can buy the rain shower set separately, why need to find the water heater that have it?

bro tumpang tanya CNP 0.75HP tu bunyik bising tak? letak dekat tangki atas je ke atau letak kat bawah dekat main pipe?

No problem but it is like you are paying more for feature that you don't need.

The small pump in water heater mostly (I believe all) is not using turbine or propeller but a type of diaphragm pump.

There are rain shower water heater in Shopee without built-in pump out there. I've seen. Any specific brand you were looking at?

Yes. I believe there is maximum input water pressure limit but most specify minimum water pressure only

"You can buy the rain shower set separately, why need to find the water heater that have it?"
I don't know how to do that 😅

dulu beli tsunami pump.. bising xleh tido, beli CNP ni mula-mula ragu juga, sebab model ni baru lagi dan tak diklankan sangat
tapi lepas pasang, ingatkan lupa ON sebab macam tak dengar apa-apa.. senyap macam tak pasang

My wishlist currently Panasonic DH-3ND1MS , this one latest model and not have rain shower or DC pump
was thinking, if I buying this.. how it possible to attach rain shower ?

lazada link
Like this? Can just attach the pipe right?

There are 3-way valve you can buy, one input and two-way output. For shower you have choice of water inlet from wall and there is model that has water inlet at bottom or maybe top. Need to search.

This may give you idea

Couldn't search more. Too much work to do today
