How many hydronic heating systems are installed in the US per ye

Probably more info than you need but herein lie hours of statistical fun. From the EIA btw.

I am interested in finding out approximately how many new boiler-based hydronic heating systems are installed in the US per year.

Thanks !

between

300,000 & 400,000. It has been the same, more or less for the last 20 years.

In single-family residences

about 50-55 thousand per year of a total of about 1,300,000 single-family homes per year.

That equates to about 4%. Not a very pretty number if you ask me.

Multi-family & commercial

Census bureau doesn't seem to collect the "type" of heating system used for multi-family units, only the type of fuel and presence of a heat pump.

I can't seem to find a similar national source of commercial construction data, let alone the type of heating system used. Numerous facets in the commercial arena; office, retail, warehouse, multi-family etc.

In the commercial arena you would probably have to use square footage numbers to come up with any kind of meaningful info. I would venture to say that most larger commercial projects that SHARE a heating/cooling system among tenants are hydronic while those with INDIVIDUAL system (like strip malls, etc.) are air. Even around here where new residential hydronic systems are EXTREMELY rare, institutional (government, hospital, school, large church, jail, etc.) projects are generally hydronic.

Northeast?

Wet stuff has got be more prevalent than that in the northeast.
A cultural thing, I suppose... Can't be the cold weather, it's plenty cold elsewhere. Or perhaps it's the A/C angle.

It's all there

In general Northeast region it's showing about 25-26% of new detached single-family homes heated hydronically in the last 6 years. This is down significantly from the 10 years previous when it was 36-38%.

There would likely be significant sub-regional variations in the general "Northeast Area" as well.

Remember these are new single-family detached housing starts ONLY. It doesn't reflect existing structures nor would it include air-to-hydronic conversions (or vice-versa)in existing stock.

If you want to make a "guess" as to the A/C factor use "U.S. 'housing starts' 2002" in google to find the overall data from which the link above is only a portion. I glanced at the increase in A/C in the Northeast and it seemed to parallel the decrease in hydronics. Don't think however that the A/C "thing" is the ONLY thing affecting the numbers--such is the problem when you start playing with statistics. The best you're likely to "prove" is possible influences and general trends!
