Comparitive efficiencies Hydronic vs. HVAC

Mark Evans

I am researching an article that will appear in HPAC Magazine- a Canadian trade publication. As a participant in the heating and plumbing industry, I have long heard efficiency touted as a selling argument used to compare hydronics to HVAC, where hydronics are presented as the more efficient choice. I would like to know the science that supports these claims and use this in the article. I have asked Mr. Holohan for permission to post this as I want the motive for asking to be clear- I would like to be able to provide facts to support the claim. For those who reply, I will be including those postings of interest and giving an attribution as to the respondent and the source (The Wall). If you wish to be confidential, please reply privately to me at writemarkevans@hotmail.com

Thanks,

Mark Evans.
