Unfortunately, our hot water tank unit started leaking and could not be repaired (I redid the stainless steel tank gasket and replaced the o-rings but it did not succeed, the parts connected to the tank kept leaking elsewhere, and elsewhere...). It is always a pity to have to throw something away (or send it to recycling, when possible) because less than 1% of it fails...

The replacement was not too expensive and easy to install product-wise (the location under the sink is cramped but the product has no responsibility in that regard).

The dispenser now works like new. I hope that the design of the heater tank has improved and that it stays that way for a long time. 

The filter is a welcome addition, but the removable cartridge should be recyclable or refillable.
