    compact solar heating module

    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.

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