    Sunboard Radiant Heat Panels

    Hey Guys,

    I'm looking to convert from forced hot air to radiant heat. Since I'm going to be redoing most of the flooring on the first floor I'm thinking I may as well do the radiant heat. Second floor I'm thinking of doing base boards since I don't want to rip out all of that flooring. My question is, will just radiant heat on the first floor heat the whole main level - or will I need base boards as well? Also, there's a local company here on Long Island (NY) that does Sunboard Panels... Has anyone ever heard of this? Any experience with them? Any Good?

    Thanks for any and all input!

    radiant floors with baseboard

    Will require two different ODR curves and may not perform the way you expect.  High-output baseboard will improve things, but panel radiators or even better, radiant ceilings would be my choice.

    No experience with Sunboard - they look similar to Warm Brothers, which has an aluminum surface but no metal in the grooves.  If so, it will need 5-10F hotter water than WarmBoard or RauPanel will.

    would I be better off just doing base boards throughout the whole house than?

    certainly not

    Radiant heat requires surface area, and baseboards just don't have much of that.  They work almost entirely by convection, which requires hotter water and is generally less comfortable.

    Run the numbers for the ground floor and see what your design temp needs to be.  Then look at options for the second floor.  Radiant ceilings should be a perfect match when properly designed.  Plate radiators can use 10-20F hotter water when sized for that.  The difference between those two curves will be far less noticeable than the 60-80F difference baseboard will require.

    Don't overlook the limitations that radiators and baseboard both impose on furniture layout.  Decorators and wives are generally happier without them.

    now the house is on a slab, no basement. my concern is about these panel systems, like sun board, which i mentioned already. are they enough to heat the main living area without any supplement to the radiant floors. i have no experience with these radiant panels? any reccomendations? do you think these sun board panels will do?

    house on slab

    Is the slab insulated underneath?  If not, you should be looking at RauPanel, Roth, or something else which does not conduct much heat downward.

    That I don't know. How would I know if its insulated underneath?

    When was it built?

    will tell us if further exploration is necessary.

    If you decide on floor heat, isolate or you'll spend about a third of your fuel heating dirt.

    better off doing

    Whatever produces the most radiant energy at the lowest cost and the least disruption of the living space.  Radiant ceilings, radiant walls, and panel radiators should probably be on your short list.

    Just an observation....

    Long Island here also.. I have the Sunboard panels in my home under a hardwood floor.  It was a last minute addition to a very large remodel project... Money was getting tight, so I cheaped out and got the 5/8 OSB panels with the thinner aluminum sheet. 

    The aluminum does extend into the tubing channels for some direct contact with the tubing, though it's only about 3/8" on either side of the channel.  

    Standard 2" flooring nails barely extend below the radiant panels, so the bulk of the holding power comes from the OSB... Next time I would step up to the plywood panels he offers.

    Good to know

    Do you use just the sunboard panel solely for heat? Does it heat enough?

    No issue keeping the place toasty.  Im running a Vitodens 100 on outdoor reset...
