7" Quik Trak™ Panel Calculations

To determine the number of Quik Trak™ panelsand Return Trak™ panels, use the following formulas:

Net Floor Area x 0.386 = # Quik Trak™ panels(round up to the next whole number)Net Floor Area x 0.043 = # Return Trak™ panels(round up to the next whole number)

ExampleGiven a 375 square foot room,375 x 0.386 = 145 Quik Trak™ panels needed375 x 0.043 = 16 Return Trak™ panels needed

These simple formulas provide you with thenumber of Quik Trak™ and Return Trak™ panelsneeded for each room.

7" Quik Trak™ Tubing Calculations

To calculate the amount of tubing needed,multiply the net floor area by 1.7. Divide thetotal amount of tubing into equal lengths thatare less than 250' including the leader lengthfor the loop. Leader length is the distance fromthe manifold to the room and back to themanifold plus the vertical distance from thefloor to the manifold.

Note: The leader length is doubled toaccount for supply and return runs.

ExampleGiven a 375 square foot room with a leader

length of 15' between the room and themanifold location, calculate the number ofloops required and the average loop length.

375 square ft. x 1.7 = 638 linear ft.638 ÷ 3 = 213 average active loop length15' (leader length) x 2 = 30'213 + 30 = 243' total loop lengthThe 375 square ft. room will require 3 loops

of 243'.

The design assistance sheets on page 5 & 6will help with the process.

Note: Do not exceed 250' for the total looplength.

Heat Loss

Wirsbo Radiant Express computer designprogram performs heat loss calculations andautomatically determines the amount of tubing,GPM flow, water temperatures and other informationnecessary for your specific installation.

If you do not have Wirsbo’s Radiant Express,perform a room-by-room heat loss. From the heatloss information, divide the Btu/h load per room bythe available net floor area (i.e., area that will haveinstalled panels) to determine the Btu/h load persquare foot of net floor space.

See the design sheets on pages 5 & 6 forcalculation assistance.

When designing the system, Wirsbo recommendsthat surface temperatures should not exceed 80° Ffor a solid wood floor and 87.5° F for any other floorsurface.

Note: If the Btu/h/ft.2 load exceeds the Btu/houtput of the Quik Trak™ panels or recommendedsurface temperature, supplemental heat is required.Wirsbo’s Radiant Express will give you thisinformation. You can deliver supplemental heat to aspecific area by using radiant wall or ceiling,baseboard, radiators or hot water convectors.

10" Quik Trak™ Panel Calculations

To determine the number of Quik Trak™ panelsand Return Trak™ panels, use the followingformulas:

Net Floor Area x 0.28 = # Quik Trak™ panels(round up to the next whole number)

Net Floor Area x 0.043 = # Return Trak™panels (round up to the next whole number)

ExampleGiven a 375 square foot room,

375 x 0.28 = 105 Quik Trak™ panels needed

375 x 0.043 = 16 Return Trak™ panels needed

These simple formulas provide you with thenumber of Quik Trak™ and Return Trak™ panelsneeded for each room.

10" Quik Trak™ Tubing Calculations

To calculate the amount of tubing needed,multiply the net floor area by 1.25. Divide thetotal amount of tubing into equal lengths that areless than 250' including the leader length for theloop. Leader length is the distance from themanifold to the room and back to the manifoldplus the vertical distance from the floor to themanifold.

Note: The leader length is doubled toaccount for supply and return runs.

ExampleGiven a 375 square foot room with a leader

length of 7' between the room and the manifoldlocation, calculate the number of loops requiredand the average loop length.

375 square ft. x 1.25 = 469 linear ft.

469 ÷ 2 = 234 average active loop length

7' (leader length) x 2 = 14'

234 + 14 = 248' total loop length

The 375 square ft. room will require 2 loops of248'.

The design assistance sheet on page 6 willhelp with the process.

Note: Do not exceed 250' for the total looplength.

Quik Trak™ Installation Methods

Quik Trak™ Installed Above A Subfloor With Hardwood Finished Floor

How: Quik Trak™ panels are laid out over aplywood subfloor perpendicular to the finishedwood floor (see page 15). Make sure to staggerthe seams of the Quik Trak™ as shown in Figure 5on page 16. Panels should be secured to thesubfloor with 1¹⁄₄" screws. To start, secure oneside of the panel with a screw on each end. Thisallows for quick realignment if needed. When thepanels are properly laid out, secure each panelwith 10 screws, five on each side of the groovefor full length panels.

After the panels are secured, use a vacuum toclean debris out of the panel grooves. Next,apply a thin (¹⁄₈") bead of Wirsbo Quik Trak™Sealant throughout the entire length of thegroove. The sealant is 100 percent silicone andacts as an adhesive agent while promoting goodheat transfer from the tubing to the panel.

Begin the installation of the tubing asdescribed on page 18.

Where: This application is used in residentialconstruction as an alternative to both joistheating and poured floor underlaymentinstallations. Quik Trak™ is also beneficial when

the finished floor material is hardwood. Installerscan actually see the tubing when laying downtheir hardwood. This method has severaladvantages over both options, including minimalfloor build-up, no concrete and increased Btu/houtput potential over joist heating.

What To Look For: Hardwood floors shouldalways be installed in accordance with theflooring manufacturer’s instructions. Nails for thefinished wood floor must be a minimum of 1¹⁄₂"away from the tubing.

Proper insulation is critical to the performanceof Quik Trak™. A minimum of R-19 isrecommended in between the floor joists.

Notes:• Surface temperature for hardwood floors

should not exceed 80° F.• Dead spots need to be filled in with plywood

strips or other suitable filling material.

In all Quik Trak™ applications, themaximum loop length for the ⁵⁄₁₆" hePEX™plus tubing is 250' including leader lengths.Flow rates for all Quik Trak™ installations arecalculated to a 20° temperature differential.

How: Quik Trak™ panels are laid out over aplywood subfloor, perpendicular to the floor joists(see page 15). This strengthens and stabilizes thesubfloor/ underlayment sandwich. Make sure tostagger the seams of the Quik Trak™ as shownin Figure 5 on page 16. Panels should besecured to the subfloor with 1¹⁄₄" screws. To start,secure one side of the panel with a screw oneach end. This allows for quick realignment ifneeded. When the panels are properly laid out,secure each panel with 10 screws, five on eachside of the groove for full length panels.



Where: This application is used in residentialconstruction as an alternative to both joistheating and poured floor underlaymentinstallations. This method has several

advantages over both options, including minimalfloor build-up, no concrete and increased outputpotential over joist heating.

What To Look For: In tile or linoleuminstallations, the finished flooring manufacturersmay require that a minimum ¹⁄₄" layer of plywoodor a ³⁄₈" layer of cement board is placed over theQuik Trak™ panels. This gives a flat, solid basefor a thinset application.


Notes:• Surface temperature for hardwood floors

should not exceed 80° F.• Dead spots need to be filled in with plywood

Quik Trak™ Installed Above A Subfloor With Carpet

How: Quik Trak™ panels are laid out over aplywood subfloor (see page 15). Make sure tostagger the seams of the Quik Trak™ as shownin Figure 5 on page 16. Panels should besecured to the subfloor with 1¹⁄₄" screws. To start,secure one side of the panel with a screw oneach end. This allows for quick realignment ifneeded. When the panels are properly laid out,secure each panel with 10 screws, five on eachside of the groove for full length panels.



Where: This application is used in residentialconstruction as an alternative to both joistheating and poured floor underlaymentinstallations. This method has severaladvantages over both options, including minimalfloor build-up, no concrete and increased outputpotential over joist heating.

What To Look For: Carpet and pad may beinstalled directly over the Quik Trak™ panels.Care must be taken to make sure all dead spotsare filled in with Quik Trak™ panels, ReturnTrak™ panels or plywood filler. Padding may beglued directly to Quik Trak™ panels. Carpet tackstrips must be a minimum of 1¹⁄₂" away from thetubing.


Note:• Dead spots need to be filled in with plywood





10


Quik Trak™ Installed Over Concrete

How: First, a layer of ⁵⁄₈" or ³⁄₄" plywoodsubfloor must be installed over the concreteslab. The plywood can be adhered directly to theconcrete if a vapor barrier is not required. If avapor barrier is required, then the plywood mustbe power-nailed to the concrete slab.

Make sure to stagger the seams of the QuikTrak™ as shown in Figure 5 on page 16. Panelsshould be secured to the plywood with 1¹⁄₄"screws. To start, secure one side of the panelwith a screw on each end. This allows for quickrealignment if needed. When the panels areproperly laid out, secure each panel with 10screws, five on each side of the groove for fulllength panels.



Where: This application is used in residentialconstruction over existing concrete slabs. Theplywood base together with the Quik Trak™panel only adds 1¹⁄₈" or 1¹⁄₄" in height. It is anexcellent solution when retrofitting or remodelinga cold basement.

What To Look For: A high water table willadversely affect the performance of thisapplication. If there is moisture present or if theexisting slab is not equipped with a vapor barrier,one must be installed over the slab prior toinstalling the plywood base and Quik Trak™panels.

Notes:• Use of a vapor barrier will prohibit the

installation of a plywood subfloor with glue.The plywood must be power nailed to theconcrete slab.

• In a basement or walk-out application, it isvery important that perimeter and edgeinsulation is installed for proper designperformance.

• Dead spots need to be filled in with plywoodstrips or other suitable filling material.



11


Quik Trak™ Wall/Ceiling InstallationHow: Starting at the floor level on the outside

wall, install Quik Trak™ panels parallel to thefloor. Panels should be screwed to the studs onboth sides of the groove with minimum ³⁄₄"screws. After the panels are installed, attach ¹⁄₂"furring strips to the remainder of the stud wall toprovide an even base for the sheetrock.

To install the tubing, drill two ⁵⁄₈" holes in thebottom wall plate opposite the Return Trak™panel. Feed the supply through the ⁵⁄₈" hole andattach it to the supply manifold. Vacuum thegroove. Apply a ¹⁄₈" bead of Quik Trak™ sealant.Firmly press tubing into the groove. Feed thereturn to the second ⁵⁄₈" hole and attach it to thereturn manifold. Lastly, attach steel protectorplates where the tubing crosses the studs toprotect the tubing from puncture.

Important: Wirsbo suggests that the installersupply a tubing layout to the end user indicatingradiant ceiling or radiant wall locations for futurereference.

Where: Radiant wall and radiant ceilinginstallations are a low cost alternative to radiantfloor heating and are often installed when radiantfloor is not viable as in some retrofit applications.In addition, both are often used in bedroomswhere its relative low cost and quick responsetime are valued. Radiant wall and radiant ceilinginstallations are also used where the heat loss ofa room requires supplemental heat in order tosatisfy design conditions.

What To Look For: Tubing should not beinstalled in an area where pictures may be hung.Maintain 6" clearances from bottom of windows.

Note: Design water temperature should notexceed 120° F.



12

Planning The Quik Trak™ Installation

In a concrete application, installation time will be improved by carefully planning the placement ofmanifolds and leaders. As shown above, the leaders must run above the floor.

5. Place the panels that will be used for theleaders. Do not screw them down at this time.

6. Place the Quik Trak™ and Return Trak™panels to determine the overall placement.When the panels are in place, screw thepanels down using only two screws. This willallow for quick adjustments if needed. Oncethe layout has been completed, panels shouldbe screwed down with 10 screws (per full panel) as recommended.

7. Fill in any small areas that do not have panelswith ¹⁄₂" plywood.

8. When installing the tubing, use staples or U-shaped tube fasteners to hold the tubingdown in the area in front of the manifold.

9. Once the tubing has been connected to themanifold and the system has been pressuretested, fill in the square area in front of themanifold using ¹⁄₂" plywood (trimmed to fit) or acement product that is screed to a level surface.A combination is also possible. Fill the largerspaces with ¹⁄₂" plywood pieces and smallerareas with a thinset product. The type of finishedflooring will dictate what method is used.


To save time, draw the Quik Trak™ layout on apiece of paper before you begin the installation.

1. Split the areas that will have panels into evenareas based on the number of loops. Thenumber of loops can be determined by usingthe Design Assistance Sheets on pages 5 & 6or your Wirsbo Radiant Express printout.

2. Select the manifold location.3. Choose the panel width. For a 7" panel draw a

28" square in front of the manifold location or a30" square for a 10" panel. The manifoldlocation is the area that will contain the tightlyspaced tubing running from the manifold tothe panels. This area may be larger or smallerdepending upon the number of loops.

4. To begin the panel installation, measure thedistance from the outside wall back to themanifold wall (see distance A) . Divide by .583(for 7" panels) or .833 (for 10" panels) todetermine the number of panel rows needed.Any remaining areas less than the width of apanel can be filled with ¹⁄₂" plywood.

Quik Trak™ Design and Installation

The Quik Trak™ layout must be carefullyplanned before installation begins. A well-planned layout will result in equal loop lengthsand minimal waste. Placement of the manifold iskey to determining the layout. Manifolds can beplaced either above or below the floor. Eitherlocation needs to be accessible by a servicepanel if the wall or ceiling below are finished.

Piping layout when tubing is run above the floor

Figures 1A and 1B show manifold location inthe wall because the floor is inaccessible frombelow (e.g., over a concrete slab).

Panel Direction

When possible, start with the warmest wateron the exterior walls and progress toward theinterior of the room. The direction of the panelsin the layout dictate the tubing runs.

Figures 3A, 3B and 3C show therecommended layout for the panels. The arrowsrepresent the recommended direction of theQuik Trak™ panels.

For tile, parquet and linoleum finished floors, Quik Trak™ panelsshould be installed perpendicular to the floor joists. This will addstrength to the floor and help prevent deflection of the floor.

For carpeted floors, Quik Trak™ panels should be installed parallelto the exterior wall to allow the warmest water to reach the coldestarea first.

For a wood finished floor covering, Quik Trak™ panels should beinstalled perpendicular to the direction of the finished wood floorboards.


16


Figure 4

Figure 5

Preliminary Layout

Once the direction of the Quik Trak™ panels isdetermined, a layout must be designed.

1. Mark any areas where panels will not beinstalled (e.g., kitchen cabinets).

2. From the wall, measure the width of the Return Trak™ plus ¹⁄₄" for a total of 7¹⁄₄" (seedistance A).

3. Snap a chalk line to outline each of the ReturnTrak walls (see Figure 4).

4. Determine the starting point for the supplypanel and snap a chalk line perpendicular tothe other chalk lines using a square as aguide.

Note: For accurate results, use a square insteadof the wall as a guide.

Panel Installation

1. Use a circular, power miter or table saw with acarbide blade for cutting Quik Trak™ panels.

2. Begin by laying the first row of panels parallelto the chalk line.

3. To improve structural integrity, stagger thepanels in each row so the seams are not linedup next to each other. If you have to cut thelast panel in the first row, you can use theother cut piece to start the second row. As analternative, you may cut a panel in half andbegin the second row. Continue thisstaggered pattern throughout the installation(see Figure 5).

Note: If the finished floor is hardwood,installation of a vapor barrier below the panelsmay be necessary. Check with the wood floorinstaller or manufacturer to determine the properlocation and type of vapor barrier needed withtheir product.

Panel Installation (cont.)

Begin the installation by laying down the QuikTrak™ panels and anchoring one side of a panelwith a screw at both ends (see Figure 6A). Thisallows for quick realignment, if necessary. Oncethe panels are properly placed, screws shouldbe installed on both sides of a panel. Ten screwsmust be used to ensure that the panels aresecure (see Figure 6B). Use of the Quik Drive™tool (E6050000) will speed this process andalleviate strain from bending.

Installing Return Trak™ Panels

When the Quik Trak™ installation is finished, itis time to install the Return Trak™ panels.

1. Place the aluminum strips in the area wherethe Return Trak™ Panels will be installed.

2. Trim the aluminum strips with a pair of tin snipsas needed.

3. Place the Return Trak™ panels so that theyalign with the grooves in the Quik Trak™panels. Make sure to maintain a serpentinepattern for proper tubing placement (seeFigures 7A and 7B).

4. Secure the Return Trak™ panels into placeusing 10 screws. If necessary, Return Trak™panels can be cut to provide 90° bends.

5. When Return Trak™ panels are in place,secure the half moon wood pieces with asingle screw to guide tubing turns.

Figure 10

Note: Leader length is crucial whencalculating the number of loops for a given room.When calculating the amount of tubing that isrequired, remember to add the distance for theleaders length to and from the manifolds. Referto the example given on page 2 of this manual.Also refer to Figures 2A & 2B on page 14.

Final Floor Preparation

Use ¹⁄₂" plywood or similar product to fill anysmall areas not covered by panels (see Figure 8). This will make for a completely levelsurface. When installing panels on a suspendedwood floor with access from below, determinethe locations of the supply and return holes tothe manifolds (see Figure 2A & 2B on page 14).

Tubing Installation

When the manifold location is below thesubfloor, each supply and return run requires a ³⁄₈"metal bend support to ensure tubing alignmentthrough the subfloor. To compensate for the bendin the support, you must create a rectangular slotin the subfloor.

First, use the ⁵⁄₈" drill bit and drill two holes sideby side (see Figure 9). Then, use a sharp woodchisel to square off the hole. Trim ¹⁄₂" of thealuminum backing out of the groove. This willallow the ³⁄₈" Metal Bend Support (A5110375) to be flush with the top of the panels (see Figure 10).

Next, vacuum the groove to remove all debris.Begin the tubing installation by attaching thesupply side to the manifold using the ⁵⁄₁₆" QuikTrak™ Fitting Assembly (A4020313). If the leadercomes from under the floor, feed the loop throughthe floor and attach to the supply manifold.

When installing the panelsin a room with an alcove orbay area, remember to allowenough room for the ReturnTrak™ panels.

Fill any areas not coveredwith panels with 1⁄2" plywood.

Quik Trak™ Tubing Installation

Tubing Installation (cont.)

Once the tubing is attached to the supplymanifold, secure the ³⁄₈" Metal Bend Support(A5110375) to the tube where it comes out of thefloor from the supply manifold. It is best to firstsecure the bend support on the side of thetubing that will remain below the floor. Thenposition the bend support at the desired pointon the tubing and snap the tubing into place.Finally, push the metal bend support into thehole that you drilled in the Quik Trak™ groove.

The tubing is now attached to the supplymanifold and is through the subfloor. Next, laydown a (¹⁄₈") bead of Quik Trak™ Sealant (seeFigure 11A). Since the sealant will becometacky in 8 to 10 minutes, it is recommended thatsilicone is applied to a section that can becovered with tubing in this amount of time. Nextwalk the tubing into the groove. Hard soledboots or shoes are recommended (see Figure11B).

If the tubing does not snap completely into thegroove, first check to see if there is someobstruction under the tube. If not, use a rubbermallet or the rubber coated base of a hammer totap the tubing into place.

Repeat the process of applying the siliconeand walking the tubing into the groove until youare a few feet from the pre-drilled hole for the runback to the return manifold. Slide the tubingthrough the hole and install a ³⁄₈" Metal BendSupport as outlined on page 18 (see Figure 10).Finish by connecting the tubing to the returnmanifold. Repeat this procedure for anyadditional loops on the manifold.

Once you are finished with all the loops to aspecific manifold, pressure test the system to aminimum of 60 psi for a minimum of 24 hours orto local code requirements. After the system hasbeen pressure tested and inspected, thefinished floor can be installed.
