Hi,

I'm after some advice.

I have what is effectively a double panel air to water heat exchanger that is used to heat/cool a house via air ducts. The unit has a fan that draws air through the exchanger and blows it from the room vents.

What is the best direction for water vs air flow - the uncooled air passing through the coldest panel first, then the warmer panel or the reverse?
