5 yr filter

"Accompanied by a horrifically leaky return system? I let our own High Efficiency filter (no longer used) stay in a bit too long and my furnace fan began to suck it into the ductwork."

Steve Waclo commented on Rick Causo's blog post What is DWHR?
"Hi Rick, My point was that while there is cold water flow into the DHW during a shower, hot water leaving the dishwasher would only be able to transfer heat to water standing within the heat exchanger. And as the delta T between the discharge water…"

"Great concept! Too bad dishwasher discharge/refill is not another possibility :-(. And for what it's worth, I let the Jacuzzi water return to room temp before I pull the plug."

Floor level return added to attic ductwork.

Hello everyone and Happy Holidays!Attic ductwork is ubiquitous in extant, single floor, single family housing and we are all too aware of the numerous shortcomings. A number of years ago, I decided to address the issue of a single, central ceiling return in my 1750 sq. ft,, 2002 home (10' ceilings) and the subsequent problems with cold hardwood floors and interminable recovery from setback.I won't review my crawl space encapsulation or the fact that I have limited setback to just one degree (it…See More

Bob Blanchette replied to Steve Waclo's discussion Floor level return added to attic ductwork. in the group HVAC
"Why use insulated flex if the return duct is in conditioned space? You could have used a 10" hard pipe, but you would have been limited by the 5x14 return anyway. My house is similar, 10' ceilings, 1999 construction, 150sqft less, slab…"

Underperforming? Energy Efficiency of HVAC Equipment Suffers Due to Poor Installation

Hello all,A search of the site seems to indicate this recently published study from NIST has not made an appearance, so here's a link to the summary page. There is also a link to the full report at the bottom of the summary and judging from the slow pace of my "loading bar" I suspect it to be voluminous.No major surprises in the summary and no doubt the full report serves to scientifically quantify what all competent installers and energy pros already know.For the extraordinarily busy folks out…See More

Professional Interests
all aspects of home energy management including passive solar and real time energy use monitoring

Have a lot of time on my hands since retirement and enjoy following developments in all aspects of residential energy management. During the Carter Administration (!) I worked in Technical Services for PEPCO in DC and helped numerous residential, commercial, industrial and governmental customers understand their bills and better manage all aspects of their energy consumption. Been out of the business for a long time, but got involved again when utility costs in our 2002 home were higher than they needed to be. Penurious by nature but concerned about the future as well (although, when you think about it, what have future generations ever done for us?:-)

Look forward to following developments here and perhaps making a contribution on occassion.

EPA Seeks Public Comment on Draft Environmental Protocols for Home Energy Upgrades

Posted on November 23, 2010 at 1:00pm 1 Comment

Hello All:



With so many HEP participants already being deluged with relevant (and sometimes irrelevant) information about the industry, it's difficult to decide when to add yet another layer by posting a press release such as this. For those who are top of this, forgive me. For those who aren't, and pretty much don't care, hope you'll forgive me too...



During my brief time with this group, I have come to very much respect the remarkable level of…
