Re: Summer shut down and 8 way treatment
@ethicalpaul it was the winter time and I didn’t know about the burnham problem. And it made sense to get it to line up to the existing drop headers and basically slide a new one right in. Even the guy who did it didn’t like burnhams but bc of those reasons I went with an exact replacement

Re: Magnesium anode vs Electric anode vs No anode
With the Mg Fe cell, the current is going to deposit the iron in the water on to the iron electrode, the pipe. It takes very little iron in the correct oxidation state to be orange to dye the water orange although that looks to be in an insoluble state. A toilet tank starts to get that type or precipitate pretty quickly. It may be in a clear and soluble oxidation state until it gets better contact with air where it changes to an insoluble orange oxidation state.

Re: Magnesium anode vs Electric anode vs No anode
Patenia is the term ued to describe the film of minerals that form on a pipe or tank. This coating served to protect the underlying metal. Similar to anodizing a piece of aluminum to protect it.
One of the ingredients in a hydronic conditioner is a film provider that puts a thin coating on all the new metal surfaces to help prevent their corrosion.

Re: The Little-Known Story Behind a Popular Tool
That's about as rare as a screwdriver that only turns counter-clockwise. I have one of the few, for setting Pressuretrols, and it only leaves my possession over my cold, dead body.

Re: Snowmelt PEX loop max length
A Class1 SIM tries to keep up with a snowfall predicted in your area.
So it requires more BTU/ sq ft. than Class 0, so more tube, more boiler, etc.
Note the 3 temperatures on glycols, freeze, slush and burst. 50%is a -80F burst.
It varies from brand to brand, this Fernox at 50% is pumpable down to -20F.

here is the correction for the pump, although all this should be in the LoopCAD program?

Re: Summer shut down and 8 way treatment
good points @ethicalpaul
What is your opinion on filling the boiler up to the top with 8 way in the water? Versus filling it about 3/4 up the sight glass with the 8 way mixed in? Any protection ? My last burnham developed a hole above the water line after about 16 years
