what is the brand of water pump?

so which is the best way if i want water heater and shower head?

Even that Panasonic heater comes with its own overhead shower, it is not as powerful as what you think.

Joven for storage water heater, grundfos scala2 for water pump.

For mixer, I use external mixer for easier maintenance and future replacement if needed.

Below is the image when first installed.

Yup

I think you are comparing 2 shower systems, here are the pros and cons.

1. Rainshower with hidden water heater (hotel-like experience)
a. Pro - Luxurious | with high water flow and high range of temperature adjustment capabilities, hot enough to use to fill up bathtub.
b. Con - Expensive parts and installation / servicing cost.

2. Rainshower with instant water heater
a. Pro - Components required are much more cheaper than option 1, and much cheaper installation cost.
b. Con - Subpar water flow and warm water just enough for shower, but definitely not for bathtub usage.


Things required for:

1. Rainshower with hidden water heater (hotel-like experience)
a. Cold and hot water pipings (Cold to water heater and mixer; hot from water heater to mixer)
b. Mixer (for u to mix the cold and hot water to get the ideal temperature for yourself, like what u see in hotels)
c. Standalone rain shower set - usually has larger nozzles compared to those that comes with instant water heaters, hence output water flow is more high pressure / luxurious
d. Powerful external water booster pump - like Grundfos, to boost your house's water pressure. beware if pressure is too high it might destroy substandard pipings around the house. This pump can be quite loud.
e. Hidden water heaters, either:
i. Storage water heaters - Go for enamel-coated storage water heaters (brands like Centon / Alpha) which is newer technology and more resistant to leakage, and not stainless steel storage water heaters (brands like Joven / Elton) which is older technology and more prone to leakage and more expensive.
ii. High-powered instant water heaters - up to 7kW ones (brands like Beebest / Centon), but still not as hot as storage water heaters.
f. Expensive installation and plaster ceiling modification to fit in the water heater above the ceiling.

2. Rainshower with instant water heater
a. Cold water piping only (to instant water heater)
b. Instant water heaters with rainshower set - the higher kW the hotter the output water temperature. But definitely still not as hot as storage water heater. And the built-in pump in instant water heater is wayyy underpowered compared to external water booster pump.
c. Basic installation. No plaster ceiling modification required.

so how do I solve this problem?
