I'm confused about why such expensive units need to be purchased. This is a serious inquiry, not a joke or a criticism.
Absolutely a legitimate question. I don't know about other units, but the unit where I work had an issue with an infectious outbreak. Though it could never be proved (all water sources and sites were cultured), it was felt that city water could not be trusted to come into contact with milk bottles or on infant's faces or mouths (even for routine bathing).
Until we got the medela warmers, the only option for warming cold milk was to set the feed in an infant's isolette if one was lucky. Also, some areas (not all), had a warming cabinet, but it took approximately 1 minute per ml to adequately warm a cold feed.
Thawing frozen milk was a particularly long and frustrating process taking hours (usually 2-3 hours for a full bottle). We were only allowed to set the bottle out on the counter, or place it in a fresh biohazard bag inside a graduate container and then we could fill the container with room temperature sterile water, which in my opinion held the cold in and made the process longer.
Now we may use the medela warmers for thawing also, though I haven't done it yet.
