The new USB-Connect smartphone app streamlines installation, service and troubleshooting for condensing and combi-boilers.

REHAU’s EVERLOC+ R-20 manifold connectors for hydronic applications support leak-free reliability in a one-piece assembly including an EVERLOC+ insert with a pre-installed O-ring and swivel nut.

The luxurious Wythe Hotel in Brooklyn, New York, was once a waterfront barrel and rope factory. This renovated structure now has 72 boutique guest rooms. As part of the update, it was important to retain the character of the original turn of the century building, which opened in 1901. In order to convert the cold, utilitarian factory space into comfortable rooms, a major mechanical update was required. By adding radiant floor heat, they were able to meet and exceed the comfort benchmark of a modern-day hotel while balancing for energy efficiency.

Integrated Dynamic Control (IDC) is a PC-based intelligent control system delivering optimized comfort and maximized efficiency by coordinating HVAC, IAQ and hydronic systems in one control.

Lochinvar’s CREST with Hellcat Combustion Technology commercial boiler is available in eight models ranging from 999,000-6,000,000 Btu/h.

Ever since the RPA was formed, members have taken advantage of the great benefits the alliance has to offer, such as codes and standards advocacy, a job center network, obtaining and creating valuable education, the annual Radiant Flooring Guide, newsletter subscription, discounts for IAPMO products and services, access to webinars and more. RPA members are professionals from all facets of the radiant profession, including manufacturers, installers, engineers, architects, students, apprentices and inspectors.

Last month, we discussed the role of buffer tanks in combination with air-to-water and water-to-water heat pumps that operate as “on/off” devices. The buffer tank allows the heat pump to operate with reasonably long cycles (e.g., it prevents short cycling) when the hydronic distribution system is heavily zoned, and thus subject to “micro-loading” at times. We also discussed how some buffer tanks can do double duty as both buffers for space heating loads and domestic water heaters. The key concept was to turn the heat pump on and off based on changes in the buffer tank temperatures and not based on thermostats calling for heat.

The very first installation of the Mikrofill 3 hydronic pressurization unit in North America took place recently in a mechanical room of an assisted- and independent-living community in Southwest-suburban Chicago. You might say the flower of this innovation grew from the soil of an old industry friendship.

Can you spot at least six design or installation details that are going to create problems?
