Disadvantages of the tankless water heater?
 

I plan to change a water heater and am looking at getting a tankless one. I found several ones from noritz. are these tankless water heater really more efficient than conventional ones?

are there any disadvantages?


thanks

I had one installed in my new house, installed the electrical lines during construction and everything. After 6 months of actual use I was so dissapointed I took it out and sold it on ebay. Bought a traditional tank heater and have been happy ever since.

Just my opinion, but I think they are way over-rated.

Very expencive to buy and install, will need maintance from time to time due to minerals building up on the sencer that detects flow.

Tankless heaters are pricey.
