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.

Remember Boston tees? Most people call them cleanouts now.

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

Re: Bathroom Remodel - Some Basic Insulation Questions for Radiant Floor
I have done 3/8 tubing over a subfloor with a wet bed and tile with good results … I'm wondering why the OP would not want to insulate under the floor since he has the ability to do it ? You want to insulate.
I think over stuffing the bays with something like rockwool and making a small cut in the rockwool for a tube in the panel would work … this would force the panel against the subfloor when you install it. Maybe even the smallest about of some thin adhesive just in case.
Even 3/8 tubing is going to raise the floor.
Warmboard recommends cement board installed above the panel for tile

Re: New refrigerants Epa 608
What's the point?
When you've got equipment being engineered / manufactured poorly that dumps how many thousands of pounds? of refrigerant into the atmosphere per year, why does it matter? I've got a feeling it's thousands of pounds per month……….but I really don't know.
Now, some will argue the equipment leaks because it's made so thin to meet efficiency requirements. If that's the case, then those requirements are wrong and need to change.
