Add-A-Zone Radiant Floor Heat Packages for Framed Sub-Floors:

Add-A-Zone pkgs. are designed for adding radiant floor heat zone(s) to existing HRH systems. The tubing can be installed under or above the floor, just add the tubing installation supplies applicable to your installation (See "Tubing Installation Supplies" below). Add-A-Zone pkgs can be configured to operate independently or in conjunction with your existing hydronic heat system. Heat Source, expansion tank, thermostatic mixing valve, tubing installation supplies and std. piping/fittings between the heat source and manifold are not included (see the Additional Components and Tubing Installation Supplies categories below).

Tubing Installation Supplies - The HRMVS0xPACZ packages do not include tubing clamps or heat transfer plates. Order the appropriate type and quantity of tubing installation supplies applicable to your specific installation.

CLJ3 J-Clamps - snap over the tubing and include an attached nail for quick installation. Recommended for securing the tubing between the manifold and the heated area with 32" spacing, or less. Also used to secure the tubing to the sub-floor when heat transfer plates are not used. Available in a 100 pack (CLJ3MV100).

CLE3 Economy Clamps - Also known as Strap Clamps, Economy Clamps fit around the tubing and install with screws or nails (not included). Recommended for installing tubing over existing concrete (using a RAM-SET with washered fasteners) and for other areas where screw-in installation is desired for easy relocation or removal. Recommended spacing is 32"or less. Available in a 100 pack (CLE3MV100).

HRTP3a Heat Transfer Plates - Approx 5" wide x 20" long with a round channel for 1/2" Pex tubing, these aluminum plates install with Groove Tube (HRGT) heat transfer adhesive over the tubing in the joist cavity. They heat up with the tubing and dramatically increase the direct heat transfer to the floor, resulting in quicker heat-up and minimizing "cold-spots". Install heat transfer plates 1" to 5" apart (end-to-end) over the tubing along the entire joist cavity starting 8" to 12" from both ends (to allow for a 5" radius U-turn at the end of the joist cavity).

Additional Components:

Expansion Tank - Expansion tanks with auto-fill valves are recommended for all closed HRFH systems. Use HRMVSFT109 for systems with heat sources up to 50,000 BTU's, HRMVSFT110 for systems from 50,000 to 100,000 BTU's and HRMVSFT111 for systems over 100,000 BTU's. Standard expansion tanks (without auto-fill valves) can be used for closed systems which have the auto-fill valve installed on another component. Use HRMVSEX15 for systems with heat sources up to 50,000 BTU's and HRMVSEX30 for systems from 50,000 to 100,000 BTU's.

Thermostatic Mixing Valve - (HRTV4, HRTH4th, HRTV5 or HRTV5th) is required on HRFH systems if the heat source cannot supply the lower temperature supply water needed for floor heat (typically 90 F to 125 F). The TMV is a manually set valve installed between the main manifold supply and return lines that blends return loop water with supply water to maintain the desired supply water temperature (almost ALL HRFH zones require a TMV).

Pressure Test Kit - (MVSPTKCM) includes air valve w/cap, 100 PSI air gauge (2.0") and pipe fittings with 1" MPT adapter to connect directly to the ProRadiant SS manifold inlet ball valve for pressure testing.
