SIZING FOR KITEC BASEBOARD SYSTEMS
Baseboard and Fan Coil Systems
Kitec PEX-AL-PEX pipe is ideally suited for supply of hot water to baseboard and fan coil systems. Easily handled, bent and installed Kitec also provides quick and simple connections using Kitec adapter fittings. Copper socket, copper spigot, male and female thread adapters make Kitec connection to heating equipment easy.
And Kitec composite pipe has the highest temperature and pressure ratings of any plastic tubing, making it ideally suited to the elevated temperatures associated with baseboards and fan coils.
The following charts define Kitec flow and sizing for these applications.
