The heating elements - there are 2 in the pitot tube - are supposedly
not repairable. I had one bad heating element a few years ago and a
new heated pitot tube from DMFS was "only" about $250. If the pitot tube
is replaced you are supposed to re-do the transponder/IFR cal as you are
"opening the static system".

After working on the static system, all you need to do is check for leaks.
An airframe mechanic can perform the check and recertify the static system.
Pump the static system until the altimeter reads 1000' above field elevation
and check for leaks (less than 100 fpm is passing). No requirement to
recertify the altimeter, encoder or transponder.
