Residential Hydronic

Wall Panel Radiators

Overview

Runtal’s Wall Panel style radiators are ideal for placement under windows or on walls where floor space is at a premium. When placed under windows, wall panels help eliminate cold spots and drafts while allowing curtains to hang to the floor. Runtal Wall Panel radiators are designed to last, crafted from heavy gauge fully welded steel.. Finished with an electrostatically applied power coat paint, your project will look as great years down the road as it does the day you first install it. Our standard Wall Panel line is available in a variety of heights and widths to suit most any heating requirement or design need. For design ideas and tips, please see our Design and Planning section found at the bottom of the page.

Specialty & Made to Order Radiators

simple to Install

Uniform fittings allow each radiator to be piped eight different ways, with connections located on the side, and bottom of each radiator, and air vents on both sides. Simply select the configuration which best fits your hot water inlet and outlet piping. Continuous Mounting eliminates the need for backing. Simply wall mount (hardware included). All pipe fittings are 1/2” NPT with 1/8” NPT Vent Fittings (Manual Vent Included!). Standard Pipe Covers are also in stock.

Versatile

Whether it’s a one radiator renovation, or a whole house, Runtal has the solution. Runtal is attractive, durable, healthy, and comfortable. Runtal Wall Panels may be used as a direct replacement for bulky cast iron radiators (see tips on installation), or it may be used with water temperatures as low as 140° F, (making it a perfect radiant alternative or complement to floor heating). Runtal Radiators carry a 5-year warranty.

Operation & Maintenance

Hydronic Radiator Operation

  1. Radiators are manufactured in the USA of cold rolled low carbon steel and should be used only in closed closed hydronic systems to assure no corrosion of any system components.
  2. Proper radiator operation depends on adequate flow of water to the panel, which can only be accomplished when all the system air has been fully vented from the panels.

  3. Radiators should each be vented, with the system pressurized but in a static state (pumps off). Venting may need to be done periodically to assure a closed system.

  4. DO NOT OVER-PRESSURIZE RADIATORS:
    Most radiators are standard pressure construction. Standard pressure radiators should be tested with NO MORE THAN 50 PSI.

  5. Radiator Operating Pressure Ratings:
    Standard Pressure – 56 psi max (Tested at 74 psi)
    Medium Pressure – 85 psi max (Tested at 110 psi)
    High Pressure – 128 psi max (Tested at 184 psi)

  6. Radiators expand a maximum of 0.016 inch per linear foot of length if heated to 215°F. Piping attached to the radiator must provide the necessary expansion compensation.

  7. Flexible piping and elbowed piping are two simple ways to provide the 1/8 inch to 1/2 inch (typical) of flexibility required in expansion situations (usually series piping).

  8. Runtal Radiators require less flow rate than other hydronic heating products. If flow noise is apparent, balance the system until the noise is reduced.

  9. For a delta T of 20°F. (T supply minus T return), divide the total Btu/hr capacity of the loop by 10,000. This gives the Flow Rate in gallons per minute (GPM)

  10. Many levels of control are available today for hydronic systems. Runtal Radiators will provide nice, even heating whether operated by a simple thermostat to baseboard loop system, or an advanced boiler reset controller with motorized mixing valves, constant circulation and 2-pipe distribution.


Radiator Maintenance

  1. Hydronic system maintenance should include routine checks for piping leaks (usually indicated by frequent makeup water), and a yearly diagnosis of the system water pH to evaluate its corrosive potential.

  2. Internal radiator maintenance depends entirely on the system water makeup and proper venting. Hydronic system additives are available to passivate and protect against freezing. These additives will not significantly reduce the output of Runtal Radiators.

  3. External radiator maintenance consists of keeping the surfaces clean, and any paint nicks or deep scratches painted with touch-up to prevent any surface rust.

  4. Radiators can be painted after sanding with fine grit paper to dull the high gloss and by wiping with solvent or a tack rag. Use only oil-based enamel paint (alkyd, acrylic, urethane, epoxy) – do not use latex or lacquer paint. Use urethane or epoxy enamel for radiators located in harsh environments. Spray the paint to achieve an even coating, and let dry completely before heating the radiator.
