panasonic usually use a metal can heater
.

So, the Joven brand uses a plastic water tank that cannot withstand the inlet valve being open (high pressure) all the time?

yes.. i think so .

the pana can is 1 complete metal can unit ..
the joven can is a metal top fused to a plastic can ... that seal maybe not strong enough.

the model i own one with jet pump the other no pump already 8 Year from pana entry level series with external 0.5hp tsunami water booster can reach 4bar not even single leak all this while, either joven build quality cacat or whatever reason probably airlock on elbow causing the leak due to water hammer



Even deka non pump entry level with 0.5hp water pump also no sign of leak after 5 year use , all water heater i have no hard piping is use only flexible hose for intake , probably more atas level have more better build quality that one i tak tahu



Forgot to mention all this water heater I'm sendiri yang pasang 😂😂

Or rubber seal no good already.. the heater hot water expand the pipe and sudah longgar..

Singapore HDB like to use metal hose...

When I rented my unit I alr checked out the WH and DB box before committing to the lease..

Plus the hose is not expensive (flexihose or plastic shower hose)

Piping problem, use flex hose at inlet and outlet at water heater.

The metal length incorrect length causing leak.

Don't cheap stake, go get a unit with ELCB like panasonic

TS. if ur renting u should report this to hdb. that low grade joven instant heater is not meant to be connected directly from water inlet and to hot water outlet. it cannot take the pressure. this piping is only for storage heaters. that hot water outlet is to supply to all the bathroom in the house. no instant heater has the capacity to do that.

if this is your house..... good luck.

to others. steel exposed piping is usually used in hdb for connecting all the water inlet to your taps, storage heaters and shower and the main risk is the water storage heater which is properly grounded.

you can use instant heater but the inlet and outlet to instant heater is usually grey pvc pipes.

HDB will come to this house and take actions?

I don't think HDB will care this so small issue......

So if I use panasonic brand also will leak?

You open the watet heater cover and look inside wiring ,thermostat ,water tank before you sign contract?


The singapore houseowner so kind one?

leaking water heater with risk of electroculation you put this in the complaint form see how fast they call you. if ur landlord is trying to save money by asking a non-qualifed person to install the heater then i say go to hdb, and report police too.

if not i'll just wait then when cna reports a person died from heater electrocution and offer takziah here.

So i go to report is not good for me.

If you’re experienced you can tell without disassembly alr.

This lousy brand

Burning smell come out

that one is designed for storage water heater? storage water heater require the drain pipe.

This one is new one.

But also spoiled
