"alt.hvac is changing for the good.
All questions home owner or pro or DIY welcomed"

I posted a question there - and promptly got told by an AH that
consumers did not belong on that site. Several people jumped on his
greasy back.

I had a specific question - see below

Question posted on alt hvac
Am in planning stage of building a new home in S WI. Have talked to
several HVAC dealers - learned tube type HX are much more reliable than

clamshells - I suppose most agree with that.


Now are there differences between tube type HX's from manufacturer to
manufacturer. Most of the internal parts look very similiar - like
PC's - umpteen brands with very few manufacturer's of the basic parts.


Are there differences in types of HX tubes - if so which brand(s) are
better and why.

Responses seemed to indicate that there are differences in HX tube
design. Amen on the biggest priority being getting a system correctly
designed and installed. Now back to the question - which manufacturer
makes a better HX tube or on the flip side - whose should be avoided.
They all looked the same to me - there are some differences.

Thanks all

Thanks
