compact solar heating module

[smuggs]

Has anyone seen this solar pool heating module before? I was wondering if anybody has had any experience with it and whether multiple units could be easily connected into 2" PVC plumbing for an in-ground pool

Heat transfer is proportional to the surface area of the collector so don't expect too much from 3 sq-ft (projected collector area). I doubt it can generate 25,000 BTU per day since the sun can only deliver on average about 2500 BTU/ft2 per day at my latitude in July. 3 sq-ft even at 100% efficiency would only be able to produce 7,500 BTU maximum so I don't know how they get to 25,000 BTU.

They've been discussed several time here on TFP. Here's one of the longer threads. http://www.troublefreepool.com/aquaquick-t11101.html

To sum it up the numbers they give are pretty much impossible to acheive.
