Hot water baseboard heat

I have two rooms in my basement I want to run hot water baseboard heat too.The room is 22'x23' with 18' high walls which turns into mt trophy on the main living space. I do have 2 ceiling fans to help circulate the air. The other room is a rec room in the basement  which is 24'x22'x8'high. I was wondering if anyone new how many lin.ft of baseboard heat I should run in each room?

  • Need more info.

    Any windows? Size? Double or single glazed?



    Length of exposed wall(s)?



    "18' high walls which turns into mt trophy" What does this mean?  You have 18' ceilings? What is mt trophy?



    Is the floor concrete? If so, any insulation underneath?



    Are the walls below grade?  If anything is above grade, what is the wall construction? 2x4, 2x6?  Any insualtion?

    Heat Loss Calc

    You have to do a heat loss calculation. Once you have that you need to look up the output of the baseboards you intend to install at the water temp you intend to use.



    Taco has free heat loss software on their website. The "Flow Pro University" section will even show you how to use it.

    KCC Hot water baseboard

    Alan

    Thank you for getting back to me. All walls are exposed, the 18' high walls is my trophy room. It starts from my basement and goes to the main living area. Thats how I got the 18' high walls. There is no insulation in the the floor that I know of, and the floor will have carpet for the finish flooring. Everything is above grade. The first 8' is concrete with a 2x4 wall framed with R-13 insulation and sheetrock for the full 18' wall. (The other 10' is basic framing on top of the foundation) I have 3 windows that are 30"x45" and they are double pained Anderson. I live in is Pen Argyl, PA 18072.

    Heated Space:

    That is a very difficult space to properly heat and requires a experienced and innovative designer to design it.  A designer and installer who has had experience with a similar space not working properly and figuring a way out of it. Like fan convectors to move the air around. Hot air rises. Cold air falls.
  • Heat Loss

    There is still more information needed for a proper calculation, i.e. ceiling construction and insulation, how many windows in each room, any cold walls, etc.), but I have put pen to paper and your Trophy room would require 23,500 BTU's to keep the temperature at 68F on the coldest average day (-2F) and the Rec. room would need 15,000 BTU's.



    I figure 500 BTU's output per foot of baseboard (BB) at 180F water temperature, so you would need 47' and 30' respectively.  The ceiling fans will be a necessity in the Trophy room.



    There are many things to consider before the design is complete such as what kind of boiler you currently have, choice of heat emitters (BB, radiators, fan convectors, etc.), location of emitters, zoning, room orientation, etc. and as icesailor said, you should get the help of an experienced designer and installer in your area.

    Alan and Ice sailor

    Thank you both for your advise. I am going to just run the best baseboards that I could find, along all of my wall space. Which is alittle more than what is needed than Alan's calculations. That's the best I think I could do, if its overkill then its overkill but don't think it will be. Do either one of you have a recommendations on a brand and model?  

    Thanks again

    fans

    I do not think ceiling fans are good idea. By forcing hot air down you disrupt convection and will not able to heat the space. You need colder air to go down and hot air to go up by itself.
