    The facility I work for has a commercial size kitchen with a total of 20 hot/cold faucets (this includes 4 bathrooms)a commercial size dishwasher, and one residencial size washer/dryer. Would a tankless water heater work in this size facility? It is presently supplied by a Parker WH-300 Hot Water Boiler which has a leak in the tube bundle and is 25 years old. We want to apply best Energy Effecient System.

    Thanks for suggestions.

    It would work but you would need to calculate the GPM requirements for worst case situation and then match it with the corresponding # of tankless heaters.I have one in my house and it flows 8 GPM, so you would need possibly 6 of these .Your gas line would not be large enough and the venting is expensive.Most commercial applications , they would put these outside and pipe water up(cheaper).

    Why not use a gas boiler (Modcon) & storage tank?

    How about electric ones. They can flow up to 12 gpm's depending on the delta T you need.
