However, advertising via the forum or PMs to its members is not allowed, but do check the options in the link above.
Consumers Reports does have an open policy about how they test. You can even visit there and see how they do it. It's fascinating, kind of like mythbusters. They don't get all calls right, but by and large they are a reputable testing lab that provides useful information. OTOH, I don't place a lot of credence in website reviews on manufacturer or seller's sites. It is too easy to plant great reviews and filter out critical reviews. Witness Northern Tools' glowing reviews for $300 electric heaters, Magic Heats, Vogelzang box stoves, etc.
For the open fireplace I would look at installing one of these devices at a minimum. (broken link removed)
Or better yet, a nice Jotul insert to match the F500 in looks and performance.
