Pool heating

Snowmelt

When doing a pool heater with a HE unit & a flat plate hex what kind of pump/ equipment do you use to bring the pool water to the hex?

Pool

You normally see them piped in series with the filter. They just use the pool recirc pump to move the water.

A flat plate HEX will have a fairly high head loss and is prone to gumming up.

You might look at something like a Triangle Tube Maxi-flo.

What about

These companies that advertise flate plate heat exchanger for pools, or am I better off getting what you said, something in a tube type product.

Caution...

If the pool chlorination systems uses salt, your regular flat plate heat exchanger WILL turn into Swiss cheese in a year or less. Chloride stress cracking. Use a material that is compatible with sodium if it is present.

Poor

I in the poor section of nj, so that would chlorine pool not salt.

Maxi-Flo

As Carl suggested above http://www.triangletube.com/documents/12/MF%20Literature%20S.S.%20&%20Titanium%202013.pdf

Salt:

You mean like Sodium Hypochorite?

surface area

is what heat transfer is all about. Look at the flat plate pool HX also, you get a lot of heat exchange surface in a small HX. They can be built and sized for close approach and low pressure drop.



Need to know what temperature you have on the A side, those tube and shell need pretty good delta T with small square footage surface area, to give you high output.

Heat exchangers

Brazed plate HE do not stand up for pool use. We have for over 10 years only used titanium tube and shell HE like this:
