We are in the process of building a new home and will be installing a direct vent fireplace in the living room. The fireplace will mainly be used for viewing and emergency/supplement heat. We are looking at the Heat & Glo 6000CLX, FPX 564 high output, and the FPX 864 high output. Both of the FPX with Ember-Fyre. We looked at all three today and it's a tough decision between them. The H&G and 864 are similar in price while the 564 is cheaper. Does anyone have any input on the three mentioned? Or another that we have not seen/considered? We also liked the Mendota FV41 but it was out of our price range. Thanks for any information.
