    Watts Stainless Steel Manifolds 


    The ONLY radiant floor manifold we recommend

    Brass isn’t always best when it comes to manifolds; try Watts radiant floor heating and switch to stainless steel manifolds.

    Quality Materials and Construction

    Made from heavy-walled, DIN-standard stainless steel tubing, we ship the manifolds directly from Germany’s finest steel mills. The stainless tubing is carefully milled and machined by CNC machines and robotically welded to meet professional standards.

    For a durable and long-lasting product, seats are machined and threaded into the manifold, not stamped and pressed in like lesser-quality brands.

    Features

    Manifolds come pre-attached to mounting brackets with vibration absorbing clamps, priced in pairs. Nominal 1" diameter trunks can be joined together to serve more circuits. Visual flow meters (gpm) are located on the supply manifold and combo balancing/shut off valves on the return manifold.


    Professional Appearance and Easy to Use

    Manifolds are visible to builders and homeowners, and stainless steel offers a professional appearance. To match the appearance of PEX tubing, fittings and accessories are made of solid brass. Installation of these manifolds is easy with one-piece construction.

    For your convenience, optional accessories are available. Browse the PDF guides for a full list of features and for additional information.

    Create a Professional Appearance

    • After the installation, manifolds are one component homeowners and builders will actually see.

    Versatility

    • 1 to 12 circuits

    • 1 in. and 1-1/2 in. trunks

    • 4-wire actuators for individual circuit control

    • Mounts in a 2x4 wall

    • Easy to add extra circuits

    • Bring supply/return in from either end

    • Each circuit can be individually balanced by adjusting the valve located under the blue cap or under the flowmeter

    • Maximum flow rates are 12 gpm for 1 in. manifolds and 20 gpm for 1-1/2 in. manifolds. Individual circuit flow meters are 0-2 gpm for 1 in. and 0-4 gpm for 1-1/2 in. manifolds.

    • Circuits can be completely isolated by closing ballancing valves under blue caps and inside flowmeters.

    • Manifolds and gauges are rated to 180°F and 80 psi pressure. Fittings are spaced at 2-1/8 in. on center.

    Save Time on Installation

    • Seamless, one-piece construction

    • Already mounted on brackets

    • Easy to balance flow or find air-locked circuits with flow meters

    • Easy to measure zone temperature drop

    Accessories

    • Vent/Purge assembly

    • End cap

    • Pressure differential by-pass

    • Thermal actuators

    • Trunk isolation valves with temperature gauges

    • Circuit isolation valve

    • Circuit isolation caps

    • Sweat and NPT transitional fittings

    • IsoTherm Mixing Pump

    • Manifold Boxes
