Hey all - How often should I check my in-floor boiler fluid level? There's a tiny leak (not even enough to drip down) at the top of the boiler but besides that everything seems good and it holds pressure. I'm about to fire it up for the season but should I check the level and re-pressureize the...

"Both showed continuity in the "on" position once they were taken out but not while installed." That is a major clue...but I can't figure out the answer....what type of wall is it, any metal lathe that could somehow be effecting the current? Very strange. Another thing to do is to connect the...

When I bought our house there wasn't any service door so I rented a concrete saw and put one in! The garage was stucco so I figured that would be the fastest way. Talk about a workout! -Wilson

Heat is combination of mini-split and in-floor heat - staple up through a wooden engineered floor. My main question, why not take advantage of all the room for insulation that you can? Thanks, W

Slowgsr...What about the heat the rises to the peak of the roof, isn't that a waste of energy if its hotter up there than below, in the room? Thanks, W

yeldogt Closed Foam is 3-3.5" in the walls and 4" inn the roof. Why do you typically just stick with the 4+?

R value of the current foam is between R16-19. Why not add to that? Super insulated buildings theses days go for a roof that is R70+! Is it a waste of $ considering what I add won't be as good as the foam? THX! Wilson

Hey all, I have a foamed in garage, 2 stories, in MN. The upper room has a peak that needs 3' of insulation (see photos) as well as some of the joists spaces (2-3'). I would like the building to be as tight as possible in order save on heat and cooling later. What are your suggestions for...

yeldogt - It's not a 7/8" pex...where did you get that idea? The building is 550sf on the bottom (in cement) and 400 sf on the 2nd floor. Entire building spray foamed. Are you saying that staple up is always inefficient and not worth the cost? I have only heard that it is slightly less...

Thanks 86turbodsl, how about purging the pex that runs overhead, is that difficult to get the air out?

Ah thx johnnyradiant...good to know about the temp differences. What does the mixing valve do? Squeezer.....my system in 300' in the slab and maybe 200 above...does the Primary make sense inn a smaller system? I read..."Important note: For relatively small radiant systems, those using less than...

mike dmt....good advice, thanks! Are you saying that the vent (in your link) should be in the upper floor pex layout to bleed out any air? No run is over 300', so I'm good there. -MNWebb

squeezer...make sure the main "T's" are with 6" of each other is the idea, correct? Aren't any pumps one the discharge side of the boiler pumping away? Thanks!

FixUntilBroke - Thanks...I wonder the same thing, but it's done all the time so there must be a method.
