Morgan M Audetat replied to Rod Fox's discussion Does altitude affect AFUE? or just the input/output BTUs?
"Though Viessmann is relatively unique in the application of Lambda technology to condensing boilers, most condensing boilers (I have installed 12 manufacturers) burning natural gas will not have to adjusted for altitude up to 6,000 feet or so.…"

Morgan M Audetat replied to Rod Fox's discussion Does altitude affect AFUE? or just the input/output BTUs?
"I beg your pardon Rod, To answer your question, Dale has it right of course.  There are two ways to adjust for altitude above 2000 ft. elevation. One is to de-rate the appliance and the other is to de-rate the gas.  Here in Minneapolis we…"

Morgan M Audetat replied to Elizabeth Guinn's discussion ERV in need of backflow preventer.
"Over-kill unless you are in an arctic environment.  Back flow preventer is a device used to protect potable water from the "back-flow" of non-potable fluids that may contaminate a water supply.  Damper is the term you are…"

Morgan M Audetat replied to William Fisher's discussion Can tankless water heaters provide hot water even when the groundwater is fairly cold?
"I like recovery and it can make a tank-less water heater work where it wouldn't, even when it shouldn't. If I were in Canada I would try one out and since we design quite a few HVAC /plumbing systems there we may soon get a chance. One…"

Morgan M Audetat replied to William Fisher's discussion Can tankless water heaters provide hot water even when the groundwater is fairly cold?
"I am master plumber and familiar with recovery and tankless water heaters.  What do you pay for an installed ThermoDrain?  What will the combination tankless and ThermoDrain cost installed?  Payback and ROI for a retired couple in…"

Morgan M Audetat replied to William Fisher's discussion Can tankless water heaters provide hot water even when the groundwater is fairly cold?
"Like all tankless water heaters, but as the OP states the ground water is cold so in cold climates extra care must be taken to assure the volume of hot water, which will diminish as ground water temperature drops, is adequate for the…"

Morgan M Audetat replied to William Fisher's discussion Can tankless water heaters provide hot water even when the groundwater is fairly cold?
"We specialize in condensing appliances but few residential applications warrant a tankless water heater. I would install a 50 gallon tank type heater for a natural gas application such as yours. You can likely afford the $35/month cost of operation…"

Morgan M Audetat commented on Sean McLoughlin's blog post Programming in-floor electric radiant heat, is it worth it?
"You would need a large bathroom to see the difference. We install them both ways depending on the occupants desire.  Thermal mass has nothing to do with it. "

Morgan M Audetat replied to Bryan Pringle's discussion Dense packed cellulose in basement?
"Still wondering what the cellulose does for you? "
Apr 20
Morgan M Audetat replied to Bryan Pringle's discussion Dense packed cellulose in basement?
"Right you are. You have to ask: what will the cellulose contribute.  Here in Minneapolis we do the all the mechanical work in basement remodels and after seeing many illogical water proofing and insulation applications had to insist on a few…"

Morgan M Audetat replied to Larry Schaffert's discussion How to correctly insulate exterior wall in a 1900 house?
"Sorry, I did missed the "siding nailed directly to the framing", my grandfather would have cursing the perpetrator.  I certainly would Thermax the thing and foam the interior edges. I would also like to use a layer of XPS over the…"
