Hydronic in floor heat design

in Radiant Heating

I am looking for a place that can design a heating system that I can install for a rental property. Currently, the house is down to the studs. Ideally, I would like to install hydronic in-floor radiant, but depends on the cost. Does anyone know of a reliable company or website to which I can submit the floor plan and have a design made?

    many of the wholesale houses will do a design. Or a local rep for the tubing manufacturer. Also, some of the radiant pex manufacturers will do a design. Check their websites.

    Uponor, Viega, Rehau, Mr Pex, Watts are some of the radiant tube manufacturers. Their websites will tell you how to submit a plan or contact the rep in your area.

    Got any plumbing wholesalers near by? Ferguson, Hajoca, Standard, there are dozens of national brands. If they have a hydronics division you can probably get a design done.

    Where are you located?

    I’m also looking at cost effective systems that are easy to install. I came across Hug Hydronics. Looks very simple and they will help design the layout and provide you with everything you need for the install.

    I am doing a retrofit over current concrete slab. Creating a thermal break using Heat-Sheet R4. Can really only raise a total of 3 inches.  I would like some advice on type and thickness of concrete or self leveler to pour over a radiant heat system being installed into heat sheet r4. Do I need a vapor barrier or will the heat sheet act as such. Do I need to add wire mesh for strength? Do I need to spray primer on the heat sheet and pex tubing prior to the pour! Or can it go direct onto? Approx 2200 sq ft of which 1700 will be heated. Want to have a finished concrete surface

    Are you thinking a product like Gypcrete a gypsum/ sand based product? I would check with both the panel manufacturer and the Gyp folks about pouring over foam. Gyp products are not good as a finished floor either, they are pretty soft, scratch easily..

    I've done 1-1/2" concrete pours. Use a pea gravel mix, double the fiber reinforcement ratio in the mix. A small pickup size grout pump can pump a pea gravel mix.

    It's not exactly a self leveling mix. Possibly you could have the concrete provider add some plasticizer. That makes it flow better without watering it down.

    Just know that all concrete cracks. Expect the tiny "road map" cracks in a slab. If that matters?

    I put tubing in the walls of our master bath. The room in on the NW corner of the house.

    The tubing was snapped into extruded Aluminum plates that was in contact with the wall sheetrock. Insulation in the stud space behind the plates.

    All on inside walls and tub skirt. Keeps at 74 degrees.

    Added plates under floor at a later date. Wall heat more effective as only SR to pass thru. Floor has 1 1/4" wood and ceramic tile for resistance.
