IPS™ slashes the cost of high-end comfort!

Looking for a reliable, LEED-friendly hydronic heating and cooling system with significant savings on installed and operating costs? The Integrated Piping System (IPS™) from Williams offers high quality comfort for around half the installed cost of a typical hydronic terminal system.

By utilizing the domestic water piping and equipment already required in the building, central plant efficiency and the IPS™ Terminal unit, IPS™ delivers quiet, comfortable hydronic heating and cooling for a whole lot less than you might expect. With IPS™, you get an affordable hydronic solution that’s easy to design, manage and maintain.

Ideal applications include limited service, suite and extended stay hotels, assisted living centers, condominiums, dormitories and apartments.


  • Increased comfort - true hydronic heating and cooling comfort for a lot less than traditional systems.
  • Reduced installed costs - no dedicated piping and equipment required for space heating such as boilers, pumps and storage tanks.
  • Reduced operating costs - less equipment and greater central plant efficiency means a tighter reign on energy usage.
  • Quiet operation - out-of-site mechanical system unlike standard terminal systems or noisy, invasive PTAC units.
  • LEED-friendly energy savings – up to 70% more efficient than packaged terminal units, up to 40% more efficient than 2-pipe hydronic, WSHP or variable DX systems, no compressors or equipment in the occupied space and reduced electrical power.
  • Increased value - better comfort and lower operating costs translate into higher operating income and may increase the resale value of your property.
  • Established system with a 10-year record of outstanding performance.
  • Variable R-718 (water) – safe enough to drink!
