InSinkErator H990C-SS Euro Instant Hot Water Dispenser, Chrome

I manage a few single-family properties and used Insinkerators on some of the units since the early 1980s. The early units had stainless tanks and will last anywhere from 5 to 8 years - pretty good. The later units went cheap, using plastic tanks and usually crack within 2 years - not that good. This unit in review has the SST tank, suppose to be stainless steal tank again for reliability. However I found it only lasted under 2 years, failing to dispense any hot or even warm water. The units I use within the last 10 years only lasted around 2 years on average. Many times it turn out to be a blown fuse, a few times between a bad tank or worn out on mechanical dispensing faucet parts. To save the fuse, don't turn up the temperature on the tank to maximum. I throw in a budget to replace it every 3 years, as it's not cost effective to call in service after the warranty period. Reliability experience on my own home use is about 2 years as well. I don't have enough hot dispensing units installed to have it statistically reliable, this is just my own experience.

Very nice when it works, could have been more reliable.

The hot water dispenser is a must; particularly for tea drinkers.
This models controllable temperature is a nice feature.
I understand that the internal tank is not copper, so it should corrode a lot more slowly than the copper models.
