can i use the pool heat exchanger from a h150 with a hayward h200 pool heater?
I've never tried, but if it fits I would assume that the exchanger on the smaller model isn't rated to work with the BTU output of the larger model. Double check though and make sure. You can visit the Hayward site and look for replacement parts for each of the heaters, this will tell you what they are each rated for and will usually give you dimensions. Sometimes it's as easy as looking up the part and comparing part numbers... some of them are interchangeable between different sizes of heaters.
