[Greenbuilding] [BULK] on demand hot water heaters

[Lawrence Lile]

We use electric point-of-use demand water heaters in commercial buildings all the time.  Often there just isn't room for the conventional electric water heaters, and the stacks on a gas water heater are hard to locate in a commercial multistory remodel.  In a sink in an office, where handwashing is about the only task, a small point of use water heater makes a lot of sense. The same might hold true for a bathroom sink. They do use a lot of electricity for a short time, on the order of 20KW at 220 or 208V.

Hello Everyone,

I'm wondering if there is such thing in North America as a location 
specific on demand hot water heater. I saw them in Australia and 
other (220V) countries where there was a little heater canister under 
the bathroom sink to supply hot water to the shower and sink. Same in 
the kitchen. Brilliant idea actually, since they were significantly 
smaller than what we all know and see around these parts. The added 
advantage is that you only have to run one line, cold, throughout the 
house.

I suspect the 220 issue is the stopper as to why I haven't seen it, 
but maybe I'm not looking in the right spots.

Thanks.

Stephen
