I have an Adv 2-T that was made in I believe 1990(not at home right now to see for sure)...I received this stove from a co-worker (for free) because he wanted a small propane stove...he bought this stove brand new back in the 90's ( he gave me receipt) and paid nearly $3K for this thing...He had this stove in an addition he had built on to his house and said he only burned this stove occasionally for "looks"...by the condition(like new) of the stove I would say that was not a lie...I have a 1500 sq ft cape cod...I do have to use a fan or 2 but its -5 degrees here today and this stove is on #3 out of 5 and my first floor is 75degrees and its 70 on the second floor...uses 1 bag/24 hrs on #3.....anyway I didnt start this thread to brag but rather to see if this is the norm for these whitfields...with parts being readily available for it I am thinking about selling my VC Reliance and trying to find another whitfield....
