Good day folksFirst many thanks, especially to David, for your help in determining the needed BTU's to heat air.  It was a very good discussion for me which forced me to defend (I believe…Continue

"Realized the comment above did not make total sense.  Of course our outside dew cycles has nothing to do with interior pipe insulation.  But yes we do have pipe condensation issues.  Cold water lines (incoming temp 40F-50F) are below…"

"Hi David,  Thanks for follow up. It is becoming common to insulate the cold lines to prevent condensation now that most new construction turns basements into living space.  We have a LOT of dew cycles in our climate (probably thousands a…"

"The wood itself provides some resistance (about R-1.25 per inch for a typical stud) so you just need to butt and seal the insulation tubes to the stud face. Injecting foam into the seam seems like overkill. I would just overdrill the penetration…"

"Thanks Sean - I do not have 'wet walls' most places I will be installing the supply tubes.  So definitely cannot drill holes larger enough to allow continuous insulation in the 2x4 sticks. And even a 2x6 would not be allowed by code…"

"It's called a wet wall - in this case it should be at least 2x6/8 or even 2 2x4 walls with a gap in center to run all the branches up then hopefully through scissor trusses or I-Joists (which you can drill out that large) Now you can drill out…"

Insulating Chilled/Cold Water Lines

Good day folks,I am wondering what best practice is for insulating chilled and cold water pipes inside a dwelling regards to protecting from condensation.I will have both domestic cold and chilled space conditioning PEX circuits throughout the home. I plan on using Armaflex continuous coil elastomeric rubber insulation (1/2" thickness) for the runs between fittings.  But what do you do at framing penetrations.  Obviously I cannot drill out a 1-3/4" hole in 2x4 plates and studs, so what is best…See More

"What motors will go bad?   can the motor be changed?   Will the Heat Transfer Plats get full?  How will they get cleaned?  Aluminum fill up quick.  I find water system full of "MUD" with higher temps -…"

Sean Wiens replied to Sean Wiens's discussion Hydronic System Critique
"Lots of questions - some of the easiest ones first. I am firmly in the camp of hydronic space conditioning vs forced air. It is more efficient from an energy standpoint and radiant heat beats convection heat any day in my books.  It is also…"

Mick Lane replied to Sean Wiens's discussion Hydronic System Critique
"What is the output of the panels on 66 degree water? Especially with 75 degree air. When we do a chilled beam or radiant cooling, we always cheat with a blower coil or DX make up air unit. Also, my typical chilled water system is on a 45 degree…"

"Just in case it is not clear - the heat pump graphic was the only one available in the software used to draw this. It will be refrigerant and not water connected between the outdoor heat pump and DX2W"
