    Smile Newb with new guy questions on designing boiler/hwh system

    Hi everyone, I'm new to the forums and new to the industry. I hope with this post I'm playing by forum rules but here I go.

    I'm a rep at an HVAC dealer in CT, I have a client with an usually high hot water demand, info below
    -2500 sq. ft home
    -5 full baths
    -1 bath w/200 gallon jacuzzi (used once a week)
    -2 people there normally, but kids from college there on weekends (can be up to 7 people)
    -wife is handicapped, thus reason for large jacuzzi
    -2 laundry areas

    Currently has-
    Slant Fin 100A90 boiler (just for heating)
    1- AO Smith BTR197 100 gallon commercial water heater
    1- AO Smith TJV120M 119 gallon storage tank (currently off line due to service issue)

    He would like to replace boiler with a new condensing unit and correct the water heater issue with possibly indirect tank. Originally I proposed a Utica SSC150 (139Kbtuh boiler) with a Triangle Tube Smart 60 indirect but am having doubts.

    Now I'm thinking to oversize boiler Utica SSC200 and the tank to a Smart 120.

    I'm having a hard time getting through my head how the boiler translates into usage for domestic hot water and my coworkers and distributor reps seem to be having a hard time with getting me the info.

    Again I'm new, only in this industry for 4 months now so I apologize in advance if this is a stupid question.

    Are you a rep at a dealer, or a rep at a distributor.

    How many times must one fix something before it is fixed?
