So Dave; what do you call a gas fired heating device that heats glycol solution that either heats the air around it in order to blow heated air into a home duct system or to be pumped into a coil in a water tank to heat domestic water?

if it heats a liquid its a boiler.

But it also heats air.

it's still a boiler. ford tops in trucks!

FORD (Found On Road Dead) or maybe you like (Fix Or Repair Daily). Im a Dodge man myself. So a furnace includes electric heat. Well that clears that up. Thanks a bunch.

Amana Energy Command

That is, of course, WHEN AND IF it actually works...

Which is in all reality a packaged boiler with a fan coil.

A piece of shit HTM.

I thought I'd post that, to help in the "Thread Race".
(9mm... here we come)




and counting....

FORD (First On Race Day)

It's almost as bad as that age old arguement.... which is better.... Chev, Dodge, or Ford.... it's all pretty sad actually.

See? Didn't I tell ya Greenhornet? It will never stop... the semantics of words used to describe what we learned to defend to the end of all time! NO BTU guru will ever change their/our minds!

If it's supplying a heating coil, it's a Boiler.

If it's heating water, it's a Water Heater.

If it's heating water with the use of a heat exchanger, it's called an Indirect Fired Water Heater.

If it's a unit that is heating the structure and domestic water, it's a Combi Boiler/Water Heater.
(which can be an on demand water heater or using a domestic hot water tank acting like an Indirect Fired Water Heater)

That being said, there is a difference between an "air handler" and a "electric furnace". Being that the air handler will have provisions for a primary (1st stage) heating coil.

A true "Electric Furnace" is one that will satisfy the structures requirements on it's own, like a gas fired furnace.

A furnace is a device that uses some means of energy to create heat.
(Electric, Gas, Oil, Wood)

Any central type heating unit.........no........this won't get near the 9mm thread.

This is like a discussion on religion.

If the guru of BTU's were to officially claim and decree each and every item, be it a furnace, boiler, heater, etc... These guys would STILL dispute it.

Use the lingo that communicates your meaning.

General residential and light commercial conventions are that a furnace is a heating device, often with a blower section to move air across the heating medium. IE: Electric elements, gas fired heat exchanger, water or glycol coil, or even wood fired heat exchanger.

A boiler is a device that heats water, and the heated water is circulated to remote heating elements such as a stand alone Airhandler (Which - typically is a metal cabinet with a blower for air distribution.) These often contain a heating coil fed from a remote source, may contain an Air conditioning DX coil.

Sometimes the DX/heating coil is withing the Air handler, or downstream in duct work.

It all boils down to semantics. No ten-inpunded.

This thread would outrun the 9mm thread ... and just might, as we all argue the wording - even though we all know what we mean. But it's enevitable. Nice going!

A furnace is a heating appliance that heats air.

Furnaces do NOT heat water. Boilers heat water.

That drives me as nuts as hot water heaters do to Spotts.

A furnace is a heating appliance to me. Electric furnace, gas furnace, oil furnace. Even a Water Furnace

Many will call an electric furnace an air handler too.

To me, the outdoor unit is a condensing UNIT or heat pump. A condenser technically doesn't have the compressor, like in the big stuff.
