news:Y5Luh.315$Hb6.2@trndny02...
Hi, I live in a 70 y/o EOG rowhouse with southern & western exposure
located
in Baltimore, MD.
The house has electric baseboard heating and window air
conditioners.
Utilities were recently deregulated
and I believe I need to install a more efficient heating unit.
Might
as
well install central air at the same time.
I understand there are new high efficiency units that can save a
bundle
in
utility costs but they need to installed by
a crew that's trained to install them otherwise the are less
effcient
than
the other systems.
Recommendations for HVAC companies are also needed.
Any recommendations for highly effcient replacement windows at a
resonalble
cost?
(will chck consumers union website)
Thanks,
Mike
Depending on your local utility rates, you might want to install Heat
Pumps.
He's in Baltimore.
http://www.usepropane.com/esc/
But the real question is, what is his utility rates?
He has to enter that ( kwh ) for himself....varies considerably depending on
your location...pretty sure IM at $.058/ kwh last I checked--"cheap
hydro"...
Anyways, run the program twice, first using baseboard heat then run through
it a second time using heat pump....
Actual value entered for propane isnt important, ( unless someone is using,
or considereing converting to it)...but suggest just use same cost / gal
value both times...

IIRC my brother is getting nailed at 3 ~bux /gallon--Seattle,Wa
area.--understandably, I've disabled the gas portion of his furnace just
recently...
Still need to log further info, but appears after a couple weeks worth of
"intelligent adaptive recovery" and what with his night temps being ~ 25 and
with 45 daytime told me yesterday he might occasionally fall short by a
couple degrees tops at the morning recovery period--so guessing at least
someone actually did an accurate heat load analysis upon initial install.
Like I say, outdoors reset stat is to be permanently installed soon--which
brings out the big guns only on as-needed basis.
===
FWIW, still think the Taystat 103 is a sucky system--esp where total lockout
occurs--but still is absolutely needed where you have HP coils downstream in
the airflow from the gas HX.
Not rocket science, still will probly eventually put up a link to the
schemtic with crossed out connections etc.
Meanwhile, Joseph and Pat can also more than likely assist if you happen to
find yourself with a customer that's wanting to ramp down on gas usage,
perhaps with the attendant addition / installation of of larger capacity
heat pump system.
IIRC, your in the corn belt--then if so pay close attention to a/c
mode...dehumidifican problems and short cycling definately can be a problem
where yuo have oversized a heat pump for to deal primarily with the heating
load.
