The white big rotating one is inlet valve?

The technician last time told me his main job is to install lighting, not to work on water heaters. Maybe he also doesn't understand how water heaters work..

So the homeowner wants to save money...

Last time he told me not to use the maximum water volume; he said this would spoil the water heater.

But the water is still cold, and even after 5 minutes, no hot water comes out.

So I use maximum water volume.
This will cause leaking?


Do you think what he told me is true?

wait... the heater is connected to the hot water supply of the whole unit?

Hi,

I am not sure what you are asking.This is instant water heater but not boiler type.

Here is what I know:

The water heater that is leaking is inside the bathroom near the living room area.

There is also a bathroom in the master bedroom.

There should be one more water heater inside, but I am not sure because I have never entered the room before.

If you have any questions, please feel free to ask me.

Thanks for your reply.

plastic inlet

outlet terus shower hose

For my guess the red and blue is exiting piping, homeowners probably remove the existing boiler and install this new instant heater

If you see the diagram probably cold via instant heater and exit old hot piping shower head

ts should save all the hassle only use the incoming blue piping and only use the stock shower head+flexible hose given by the instant water heater

Since the exiting piping is conceal under the wall if the wall is cold and is long also the wall also good at absorb heat i guess by the time reaching at the end the water ia already cold

Shower output water temperature is resulted by:

1. Water heater's power rating | The higher the power rating, the hotter the output water temperature. Yours is 3.3kW 230V, possibly one of the lowest power rating in the market, hence output water temperature is only so-so.

2. Water flow rate | The faster the water flow, the lower the output water temperature (less contact time between incoming water and the heating element). So if you increase your water flow, u will get lower output water temperature, not the other way around.

3. Distance between water heater and output | The longer the distance the water heater's output water has to travel before reaching users, the more heat loss, hence the lower the output water temperature. Such low power rating 3.3kW water heater should be using their provided plastic hose and handset, not connect back into the wall (this will cause a lot of heat loss).

4. Hose material from water heater to output | The more heat conductive the material, the more heat loss, the lower the output water temperature. U are using metal, which is highly heat conductive, hence more heat loss, as compared to using the plastic hose provided with the water heater.

5. Incoming water temperature | The lower in the incoming water temperature, the lower the output water temperature.


Conclusion, if you want to use the water heater with this current piping setting, u need to get an instant water heater with higher power rating, and make sure it is using copper tank since (I am guessing) your water pressure is extremely high.

Yes. Or you could have turned off BOTH of these in your photo here when not in use

so where is the water leak from .

from pix i guess the steel pipe /black connect at the outlet ??

maybe need more tape at the joint/

Surprise TS still alive.
Change to Panasonic, use all non-metal pipes

May I know why metal pipe is not suitable for water heaters?

Internal water tank inside water heater is burst.

The cover



Water pressure too high

Why must turn off everytime ?

You got some balls

The plumber technician is quite bold. He just does things haphazardly without following proper SOP. It's not me.

Actually, I'm not sure if he knows how to change or install a water heater 100%.


He doesn't seem like a professional plumber.

My goodness, ask the expert to get it done. Save your life and also your precious time.

If ts don't want overdone suggest using this simple method, the setup your have right now are over configuration

Try not to using elbow around inlet can create air lock
On red circle


Use male to male for wall cold water



Then flexible hose all the way to instant water heater inlet how long you need i tak tahu sendiri measure but this nylon hose can sustain 3 to 4 bar without issues make sure you keep the existing oring when tighten this flexible hose if not given remember to bought 4 pcs in case water heater exit stock flexible hose dah hilang



Don't forgot all the male balut white tape in clockwise direction if you do it counter clockwise can tear up the White tap when tighten it



This is more cost effective and budget and very straightforward

If you know what you doing

Later, he will come to install a new water heater. I'm not sure if he bought a Panasonic brand or still a Joven brand.


I need to sleep now; I have a night shift later.

So, update here by me maybe around 6:15 PM.

I just rent this house. I think the homeowner wants to save money by hiring cheap labor.

Nowonder TS busted 2 heaters in the span of few months

My friend never turns off this valve at another house.


They use a Panasonic brand water heater in the bathroom, and there have been no issues for a few years already.
