Heat Exchanger Question

@ruecker

It is not what most people think of when we say heat pump. All the client really needs to know is that it can’t move heat from outdoors to indoors

Sorry to disagree Ryan, there is a difference between explaining how a heat pump is totally different from a heat exchanger…

My bad. I thought you were asking about a heat pump vs. an air conditioner, not a heat pump vs. a heat exchanger.

A heat exchanger can’t generate heat without another component such as a boiler, gas furnace, heat pump, etc.

@tglaze

does it work without an additional heat source and not on it’s own

Heat exchangers only transfer the heat they don’t create the heat.

Thank you Ryan and Neil. That was the question I was trying to confirm.

Thank you Ryan and Neil. That was the question I was trying to confirm.

It was answered twice before. AND a good deal of supplemental information. I am glad it all clicks for you now.

@bcawhern1

No. You may have an energy recovery unit somewhere in the home but I have never seen them as part of the split-system (at the air handler or built in). And, they are mostly for indoor air quality, not heating. They are not popular down south. (personally, I do not think this person knows what a heat-exchanger is or much else about these systems)

@jjonas

No!
A ‘Furnace Heat Exchanger’ is a component of the furnace, and cannot operate without an operable furnace.
Period.

And finally a third time after your meltdown.

@bcawhern1

And to be honest, the question was fouled because the seller had bad information and we had to work thru that. Of course a heat-exchanger cannot work without a fuel source, so we kept trying to decipher that BS.

Questions answer.

The 4 types of heat exchangers, and their applications.
1: Double Tube Heat Exchangers: Double tube heat exchangers use what is known as a tube within a tube structure.
2: Shell and Tube Heat Exchangers:
3: Tube in Tube Heat Exchangers:
4: Plate Heat Exchangers:

Types:

A: Air-source heat pump. Main article: Air-source heat pump.
B: Ground-source heat pump. Main article: Ground-source heat pump.
C: Exhaust air heat pump. Main article: Exhaust air heat pump.
D: Solar-assisted heat pump. See also: Solar-assisted heat pump.
E: Water-source heat pump. Water-source heat-exchanger being installed.

What the hell is going on here?!
I don’t know what the original question was, some people are on my list.

But there is all kinds of misinformation, identification, terminology and concepts which is wrongly used. That’s fine, we all use different terms and live in different countries, but this leads to “wrong”.

Let me address two subjects on this thread with a one-liner answer.

Heat Pump: A Refrigeration System that can reverse the flow of refrigerant to direct heat into, or out of a building.

Heat Exchanger: A device that “exchanges” higher temperature to lower temperature fluid (liquid or air).

As for all the discussion of how to identify a heat pump:
Look for this. If it is not there, it is not a heat pump.

I know many of you think that is a musical instrument but it is a REVERSING valve.

And one of the biggest pain in the ass parts to replace…
