I am thinking that a muti point water heater is needed if you will be using your shower, faucet, kitchen sink at the same time.

I am just curious because multi poit water heater are usually rated 6kW and above. I am not out of my mind to put it inside my house.
I just think that it is unsafe to have a load that kind of power for a house.

That's the max power, only on the initial heatup.

Exactly the point. If i am not going to use the max power, why should i install one? Right?

it will not work. Single point water heater works only in one location. Commonly used sa shower area only.

Multi point water heater serves two or more location depending on the heater capacity. It can serve two or more CR with shower or lavatory running at the same time. That is why It has a higher wattage.

One of the advantage of multipoint water heater is if your are using rain type shower head. The water temperature is controlled by the shower valve mixer. By mixing hot and cold water to attain the right temperature. While in single point water heater hot water is controlled by the thermostat and shower valve.

You will need more heat with multipoint, temperature is regulated by mixing hot and cold water. Unlike with single point, temperature is controlled by the water heater. I guess the multipoint is set for max temp mostly.

The tubing inside the point of use heater is like 3/8" diameter more or less, so your flow rate will be very limited. you will not get the desired temperature if you will let it do the work of the big one even if you max out the thermostat setting. Multi point water heater is designed for a higher flow rate hence higher kW rating.
Also, unlike electric motor where the starting current is higher than the running current, it remains constant for an electric heater as long as the heating element is energized. The thermostat will just control the frequency of cut-in /cut-off.

Just tested today with out single point water heater.
It will not work for a multipoint application because of the difference in flow sensors used compared with the multipoint heaters.
Scenario. I turned on the shower with a single point water heater then i tried to restrict the flow of water at the output of the heater then What happens is the heater stays on without flowing water. So the heating element will actually overheat if you use a single point water heater for a multipoint application.
