Competency F1: Determine Hydronic System Loads

The intent of this section of learning resources is to familiarize the learner in the methods used to estimate heat losses for buildings of residential construction. The information presented has been based on literature provided by TECA (Thermal Environmental Comfort Association of BC). TECA are an amalgamation of two volunteer, not-for-profit trade associations of contractors, manufacturers, wholesalers and agents of heating and cooling equipment. They operated in British Columbia independently as RHWHA (Residential Hot Water Heating Association of BC) and HVCI (Heating, Ventilating and Cooling Industry Association of BC) until May of 2006 when they amalgamated to form TECA. It is important to point out that all local codes and standards are to be consulted when applying the information taken from this text, specifically in the requirement for conformance to the document CSA-F280 “Determining the Required Capacity of Residential Space Heating and Cooling Appliances”.
