Hello -- I have the Greenwood Aspen 175, I have had it for 3 years now.  I am now having an issue with the unit which it is not heating my house correctly.   My digital thermometer outside reads at 177 degrees and appears (to me to be hot enough) however inside my rooms are only getting up to 62 degrees?  My furnace that I have for backup inside is an Energy Kinetics System 2000 hot water baseboard, which has a temp display on it so I can see the temp comming in from the outside wood furnace.  It appears that it is not heating the system quick enough to force the heat out to the zones?  My installer is no where to be found and the company is Bankrupt so I am in ruff shape here.  I reside in Northern NJ and was looking for someone who has knowledge to service the unit and have no luck.  I have no problems doing the work myself but really have no idea where to start? 

One last bit on info on it...  I have tried to adjust the control valave in the back of the unit which controls the supply/return.  When I do that the temp of the wood furnace drops to 166 and appears to struggle between  166 - 169?

things to look at

pump wearing out and not pushing water to the house fast enough (could be 177 degree water entering the home but not moving fast enough to keep up --tell tale sign is more than 25 degree change in temp of outgoing water on teh return line)

clogged  heat exchanger or pipe, perhaps even a valve not opened all the way (such as a zone valve?)

if water is getting to the home ate 177 and not heating your home, i am gonna guess low flow due to a worn pump or dirty (clogged) exchanger which would also cause low flow (if clogged bad enough) or just low heat exchange. the tell tell sing of low flow would be an extreme difference in the  incoming and outgoing temps when the house is calling for heat. in a well balanced system  the difference in water temps on incoming and outgoing should NEVER eceed 20 degrees.
