We've got 176° hot water coming out of the faucets right now, because I removed that Flochek valve .... due to the false advertising on my circulator.
Turns out, there's no damn IFC in there!
Came with my Amtrol Boilermate indirect hot water heater ... but I bought it at Lowe's in Worcester. Someone probably bought it, stole the circulator, installed their non-IFC circ and slapped the stickers on it, and returned it to Lowe's. Anytime you shop in Worcester, MA no matter what store, you gotta open the box BEFORE you leave the store. People pull that crap all the time. Goes to show the mentality & ethics of part of the populace ... but I digress....
No such thing as TOO MUCH hot water this winter! Been damn cold! My 2 series-plumbed hot water coils in the Mark III have sent my oil boiler north of 260° - YES .. TWO HUNDRED sixty ... several times. Melted all my insulation off the RETURN pipes!
This picture I took when I came home from work one day and smelt something funny coming from the basement. The floor was SOAKED from the relief valve blasting off, so who knows how high it really got while I was gone!
