A GFCI receptacle as a LWCO

So it's 10 p.m. last night and 13 degrees out. A neighbors house sitter calls and says the heat is out.

The system had glycol and the make up was off. It did not have a LWCO.

What it did have was a leaking boiler drain at the boiler return. As the fluid leaked out the pump ran dry and tripped a GFI the boiler was plugged into.

The pump was ruined but the boiler lives on. What a twist! A major company was there in Sept.

    Can't make this stuff up

    this might be a good place for ME's "pig" setup as well as a LWCO.

    Wet rotor?

    You dont mention what type of circulator but it happens often. The pump windings shorted to ground and tripped the GFCI.
