Hi,

 I'm putting a1story addion on my 100+ yr old 2 story home and need to add onto an existing one pipe steam system. The boiler was replaced about 5 years ago and the system works great no hiss knock or hammering.

I know nothing about steam !

I'd like to come of an existing first floor line  thru floor cross the bathroom and pop up at exterior wall adding 32 feet of baseboard. Is this too much?. Will this work?  What do you think of the slantline multi pack 80 series? Are there any other options?  Are there clearances to be aware of ?  I'd like to run close to ceramic tile floor and maybe generate some  radiant  floor heat from the line. The new floor will be tile, over hardibacker,over ply ,over R30 fiberglass ,over 1/2 foam. The house is uninsulated now but will be sealed and insulated when we're finished.

 

Thanks for any help or advice you can give. I am a carpenter and will be doing all the work myself but beyond putting pipe together ,I dont have a clue when it comes to steam. 

Thanks again

 Dave

    Looks like the existing system

    has cast-iron radiators. I like the MultiPak baseboard but it does not work well on the same system as radiators. The reason is the radiators hold their heat when the system shuts down, but the baseboard goes cold immediately. So the rooms with the baseboard are uncomfortable.



    Have you done a heat-loss calc to see how much heat the addition actually needs?

  • That is a BIG job,,

    for someone who admits knowing nothing about steam.

    If I were you, definitely get a steam pro in there.

    re help

    I have done a rescheck certification for the addition 

    Compliance Certificate maximum ua 88 Your UA: 85

    3.4% Better Than Code 2003 iecc2003 IESingle Family

    Glazing Area Percentage: 15%


    Glazing Area Percentage: 15%

    Heating Degree Days:6411
    6411

    And my design passed.

    Im not sure if this is a heat loss calc. I dont know how to determine heat needs    yet :) .

    The existing structure is ballon framed There are nine radiators and it s only a 1260 sq' home, ill be skinning it w an 3/4 airspace and  R 3.3 foam and vinyl but it will never be as tight as the new addition. Could the quicker heat loss of the existing house offset the radiators ability to hold heat  and leave me ok in the addition? I just read an article here on steam pipes not causing fire so I think Im ok w/ the bathroom floor radiant heat . But are there codes concerning clearances?.

    I know this is a big job if I could have someone else do it I would :) .I just have to make sure what Im proposing will work.  I will be able to do the installation.   I cant afford to do it twice. I appreciate any advice you guys can give.

    Thanks againDave

    Perhaps your best bet

    would be to have someone come and do the calc. I don't believe there is a free download calc program anymore that you could use- if anyone knows of one please speak up.

    Taco's floPro designer?

    I have used taco's FloPro designer (http://flopro.taco-hvac.com/) for my house .. it's free but you must register with the website before download I think... I have heard good things about the SlantFin Heat Loss program, however, I have never been able to secure a copy .. although I know it's floating around.



    FloPro also does Cooling Load as well.

    SlantFin Heat Loss Program...

    someone posted this in the Main Wall .. but it is relevant here since I mentioned it but didn't know where to find it ..



    SlantFin Hydronic Explorer .. I'm downloading it as I type, so I have no experience with it:
