Forced air with hot water

[allseason]

What would one specifically call an HVAC system that uses hot water form a boiler to heat the coil in an air handler?

[ghentjr]

Hydro Air.

I second hydro air.

[Marc]

Forced-Air Hydronic Heating System. It rolls off the tongue a little smoother, makes you sounds smarter.

[Jim Katen]

The industry term is hydro air.

[Rob Amaral]

Hydro-air is the term used by the HVAC guys..

[Tom Raymond]

Dumb.

It squanders the benefits of hydronic heat for the convenience of central air.

It squanders the benefits of hydronic heat for the convenience of central air.

Yet it is how every automobile on the planet is heated.

Cars are scavenging a waste product to make heat for the passenger compartment. It's >100% efficient from a climate control perspective.

If air was effective at moving heat then the heaters in the old air cooled VWs would have worked a whole lot better.

Hydro air works best in my climate as a solution for problem areas, like toe kick heaters. If I were trying to heat and cool a whole house I'd want two systems each optimized for their specific task. It'd be cheaper over the life of the equipment.

I've used "fan coil" to describe such systems.

seems like I had a VW in Germany that had a gasoline heater in it. I know I had a Tank Starter skid that had a gasoline heater and generator combined.

I call those systems hydro air

Hi Les,

Yeah, you're right; I'd forgotten about the VW and Corvair heaters.

OT - OF!!!

The old VW buses has gasoline supplied heaters.

[hausdok]

Yeah,

I know, so didn't the Corvair heaters. My family had a slough of those cars. They were the closest thing to having a snowplow one could have without having a snowplow. When everyone else was stuck, my family and uncles and cousins were all driving around thumbing our noses at the front-engined guys stuck in the ditch.

Anyway, my bad, like I said, I'd forgotten about those or I would never have said every auto on the planet was heated that way.

ONE TEAM - ONE FIGHT!!!

Don't forget:

Porsche

Tatra

Citreon

Panhard

Fiat

Honda

All had air cooled engines in production automobiles at one time or another.

I've used "fan coil" to describe such systems.

The fan coil is the part of the system that's inside the air handler. You can also have fan coil circuits on a hydronic boiler along with radiators.
