well i import instant geasers direct from china in bulk ,,,,so i know them from inside out ,,,, there sale is now 90% dropped,,,,,,, just because of self created problems ,,,,,,,,i know these from inside out ,,,,, there is a thermal device in water heater which cuts off the power as soon as water goes above 72 DC ,,,,,,, it happen because of low water flow ,,,,,, i am using similar kind of water heater in my home ,,,,,, 3 of such installed in my home for last more then 15 years and i am 100% satisfied with them ,,,,,, they are not cost effective as people think they are ,,,,, they consume almost similar amount of gas ,,,,,,, for example a 6 and 8L water heater has 6 burners in it ,,,,,, each supplied with gas with a separate gas nozzle,,,,,,, that mean at any given time it is consuming 6 time more gas then an ordinary water heater ,,,,,,,, where as i am using 12L in my home and they each have 14 burners in it ,,,,,,,, how can one call it cost effective ,,,,,,,, further more it is only recommended to those users who can repair it on there own ,,,,,,, just like a jeep lover must be a a half mechanic ,,,,,,, in same way instant water heater user must know a little bit about its working and mechanism,,,,,,,,
you can see in pics ,,,,, this one is fitted in my personal bathroom ,,,,,,,, using for last 15 years in another home and now transplanted it in new home and working flawlessly,,,,,,,reason because i supply inlet water to this heater directly from overhead tank ,,,,,, and then to a pressure pump ,,,,, and then it goes directly to my bathroom ,,,,,,,it will perform well only if fitted in this way ,,,,,, other wise all waste of time and money ,,,,,,,pressure pump is good enough to supply a 24 inch shower head and heater power full enough to instantaneously heater that water,,,,,,,,, you cannot expect such performance from a 6l or even 10L water heater ,,,, and not even with 12L of water heater which now a days selling in market ,,,,,, they simply print 12L on 8L ,,,,,,,, all bogus,,,,,,,all local reputed brands are selling crap ,,,,,,, all made under one roof in china ,,,,,,,, one factory making heat exchange ,,,,,, another making body ,,,, and so on ,,,,, and one collect all parts and assemble ,,,,,,
