LWCO: Probe or Float on TR50?

vaporvac Member Posts: 1,520
As I'm ordering my Slantfin trepid TR50 as a knockdown without the burner, i have to order some other bits and bobs separately. One of these is the LWCO. I've read that while the probe-type is superior, it might not work on the intrepid due to the low water levels. I can't remember the exact post now, but I did read that. Does anyone have any comment?

I would also like to know if it's possible to have BOTH the probe and float type on one boiler as as sort of backup. If it IS possible, can I reuse my current LWCOs or should they be new. Or is this just a silly idea and overkill?

As always, thanks for all the help. Colleen

    Go with the Probe

    we install or upgrade all our Intrepid and older Liberty steamers that way. They work fine on these boilers and are far more reliable than float-type LWCOs.

    There should not be a need for a float-type LWCO in addition to the probe, unless local codes require it.
