Kurt Albershardt replied to Bob Blanchette's discussion How to determine HDD's and "savings" from furnace upgrade
"We download daily degree-day data from http://www.degreedays.net/ and then total by meter reading periods.  Subtract the summer DHW/kitchen loads and then convert to BTU per degree-day per square foot."

Kurt Albershardt replied to Bob Blanchette's discussion Comparing energy cost break even points
"HUGE regional variation in energy prices.  Here in Southwest NM, residential NG currently runs $0.655 per therm, with $13.34 in fixed monthly costs.  Electric is currently $0.1275 plus $5.63 in fixed monthly costs.  All of the above…"

Kurt Albershardt replied to Jose Macho's discussion Google Nest Acquisition- Where the Home Energy Market is Going
"Sending price signals to the end user is a good thing in my book.  There's the potential here to benefit both consumers and utilities if it's done right."

Kurt Albershardt replied to Jose Macho's discussion Google Nest Acquisition- Where the Home Energy Market is Going
"Lots of complaints from steam and hydronic system owners as well.  Looks like a fail with high mass systems in general. No matter how much computing power and gee-whiz you layer on top of one, a conventional thermostat can only tell the HVAC…"

Kurt Albershardt commented on Igor Zhadanovsky's blog post Scrutinizing Condensing Boilers With the Second Law of Thermodynamics (SLT)
"Hot water is a lower quality heat source than steam.  100ºF water is a lower quality heat source than 180ºF water.  Lower quality heat is easier to obtain and generally costs less. Designing your emitter system to operate using a…"

Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"90% must be counting hydroelectric as renewable, with which some might take umbrage."

Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"Raising tank temp weekly mostly happens automatically with solar here.  No such luck with a refrigerant cycle.  In-tank electric resistance elements can easily accomplish that, but the "tankless electric as last-ditch booster"…"

Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"We have done similar things on commercial projects (preheat using water-cooled evaporators on refrigeration) but I've never quite figured out how to make it fit in a typical residence."

Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"I was mostly thinking solar thermal there, but how do you deal with Legionella protection?"
Nov 18, 2013
Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"Heat pumps and solar share a similarity in that maximum efficiency comes from sending cold water to the heat source.  Because of this, maximizing their efficiency means not heating the tank directly with the secondary source.  Following…"

Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"Intelligent controls could have a real impact here, especially if ASSE 1017 tempering valves become more prevalent.  Combine that with TOU electric rates and I believe we have a winner."
Nov 17, 2013
Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"The SHPT-50 does look interesting, but I'm having trouble finding out what the actual capacity of the heat pump is (for any of the models, actually.)  As someone who designs hybrid systems, I have been recommending tankless electric…"

Kurt Albershardt commented on Anna Jursik's blog post Electric Thermal Storage vs. Heat Pump Water Heaters
"An often-overlooked point:  Heat pump water heaters remove heat from the space in which they are installed.  The warmer that space, the more efficiently they operate.  In warm climates, this is a welcome thing almost all year…"

Kurt Albershardt replied to Jack Baikoff's discussion Real data on the magic of Low E coatings for cold climates?
"So much of this depends on the size and orientation of the window.  North-facing picture windows are more common than one would suspect, and with our high altitude dark nights, you can really feel the "suck" from the night sky. New…"
