I considered one about 5 years ago but my cousin is a plumber and he said they don't work if you have marginal quality water such as high TDS hard water. Even with a good softener, the fine tubes that the water passes through to get hot plug up very quickly. So, unless your water quality is perfect, you could have trouble.
