Hydronic heating fluid can run through long lengths of pipe before reaching a terminal unit.; heat is lost through the walls of the pipes. To retain as much heat as possible, pipes need to be insulated. Building codes require that the pipes be wrapped with __________ insulation to reduce heat loss. Insulations with R values ranging from __________ are an even better choice to improve the energy efficiency of the hydronic heating system.
