The Air-Conditioning, Heating, and Refrigeration Institute has reached an agreement with the Air Conditioning Contractors of America to have the group publish the I=B=R Residential Hydronic Heating Guide, the H-22 Heat Loss Calculation Guide and related HVAC construction worksheets and quarter-scale house plans.

Officials say the hydronic guide is one of the most definitive guides on residential HVAC market installations of such systems. 

"Since launching the Radiant & Hydronics Council in late 2011, ACCA has worked to create strategic partnerships with many organizations in the industry to provide our members with the best resources available," said Paul T. Stalknecht, the ACCA president and CEO. "We have had a long-term relationship with AHRI and have worked closely with them for many years. It only made sense for us to again work together to expand the market for the best hydronics products on the market."

The ACCA’s online store contains hundreds of similar manuals on HVAC construction topics.
