    Ultra fin Radiant heating

    I m building a 6000 sq ft home in NY. It was suggested that i use Ultra Fin System as a primary heating
    The manufacturer provided a heat loss estimate, and suggest 3700 ft of 3/4 PEX with 2100 pairs of plate
    plates
    floors will be tile and wood
    I m concerned with making sure that this system will be able to heat the house properly.
    Should I use any additional wall radiators to be supplemented to the radiant?
    Anyone with Ultra Fin Experience in the NYC area?
    Should I use a condensing or a modulating boiler??
    Thanks

    At what point

    Are you in the building Phase?

    There are other RFH methods besides Ultrafin that have higher outputs at lower water temps, and more responsive. you need to be cautious of floor temps with your wood floors. Are they solid, or Engineered wood floors?

    And last question is WHY are you concerned?

    the house is framed and roof  and windows installed.
    All joist and walls are open
    Can you suggest another RF system, and possibly someone in my area that can install it/
    Thanks

    Ultra Fin

    I found it was easier to pull a pex loop into every joist bay, instead of threading a single tube thru every joist.

    I installed the Ultra Fin on only one run per joist bay. It did take more tube but I felt better with fin every joist bay, 16" on center. I also added some ThermoFin under the large glass wall in the living room. Same loop, I just jumped the tube up into the transfer plates on the high load area.

    I'm in a milder climate in Missouri and I connected it to a Lochinvar Knight running 140F supply.

    It real tough to make tubing or heat emitter additions after the sheet rock is up. I'd error with additional tube and UF and run lower temperature supply, allowing for some wiggle room on below design conditions.

    Joist trak

    The best type of product for underfloor heating in an aluminum plate like Uponer Joist trak. You can run these at much lower temps than Ultra Fin. Low temps is the key to maximizing the efficiency of condensing boilers.
    I would strongly suggest finding a designer who can perform a heat loss calculation of your project and then properly design your system. You will be spending a great deal of money on this system, I just a few hours a good designer could be sure your system runs perfectly.

    can you recommend a good designer.I m very concerned about getting this done the right way.
    Have you had any experience with the Ultra Fin  System or heard about it??
    I do have the time to get this done right . Just completed the framing only
    Thanks

    Where in NY are you ?   You could have this designed by someone and then find a competent installer in your area .  You said The fine people at Ultra Fin designed a system for you . May I ask if they performed a room by room heat loss of the property ? If they did not they have no idea what to design unless you sent them ALL the INFORMATION REQUIRED to perform the heat loss calculations .

    Ultra fin Radiant heating

    hi Rich
    I m building in Nassau County New York. about 5 miles east of JFK.
    Ultra fin did a room by room heat loss calculation s from my floor plans and elevations
    They did include the loss for all windows, glass and openings.
    I do have a detailed Ultra Calc Room Report.
    can you recommend someone to design the system properly, check their calculations or suggest a better way of doing this.
    This js a house I plan to use myself, and it has to be doen right
    Thanks

    Ultra fin

    Mike,
    I have not and would not do a ultra fin system. The problem is you are heating the air space rather than the surface. I am sure they work just fine if you run the water hot enough. The whole point of radiant is efficiency and comfort.
    Many supply houses will help with designs or make a recommendation.
    You could also check with these guys http://www.radiantprofessionalsalliance.org/Pages/default.aspx
    As Rich said, if they are not doing a heat loss, they are just guessing.

    Ultra Fin did a heat loss calculations from my floor plans. The calculations includes the floor covering in each room as well as windows and doors.
     and Provided a Room by Room detail report
    I m just concerned since I was not able to speak to any one in the Northast that actually  did install the  system or and end user that has the system
    Can you recommend a designer or someone that can install a radiant heating system
    thanks

    Sensibility

    After much research on your part I would guess you decided to go with radiant heating for comfort and efficiency . Correct me if I am mistaken .  You did some research on the internet and found Ultra Fin and the marketing and the promise of a more economical install and first cost caught your attention . Welcome to the wortd of marketing or as I like to call it , SPIN.. Our industry is full of it , everyone on The Wall can verify this .  Think about this , water can and does carry 3,470 x more heat than an equivalent unit of air . You will be depending on heating a huge mass of air that does not hold heat well before you will feel a damn thing . To put it in size terms , your home is 6000 sq feet , all radiant , 4 inch air space acting as your heating medium , all that air must be heated before any meaningful heat transfer can take place . You are in essence heating an 82.5 sq ft room that does not exist all the time and this room must satisfy before any of the real rooms get any heat that you will perceive . Sound efficient to you ?   That air space will also cool very rapidly after the thermostat satisfies and it will start all over again . It will require water temps that are not conducive to condensing equipment so you will lose that efficiency factor also .  It is just all around not a good idea in my opinion and I am not alone

    UltraFin

    has been around since the early 1990's. In the proper application it works well, and it does not always require 180F operating temperatures. I't all about the loads and appropriate design.

    It's a step or two above the "dangled tube" suspended bare tube method that Wirsbo promoted, and another DIY company up New England way. Both are still in business and selling millions of feet of tube :)

    Actually when you view a UltraFin installation through the lens of an infrared camera it has an amazingly consistent floor temperature, no striping like some plate, or staple up rubber tube installations.
