People have used it successfully over two decades for radiant and baseboard heating connections. The tubing has been criticized for being affected by chlorine at high temperature, but this has occurred when there is a steady supply of chlorine from a water supply. This is not the condition in a sealed heating system. The newer Stadler bronze fittings and the Stadler or Wirsbo method of connectors could solve the connector problems.
