We have been recommended the RSF Focus 320, but there may be something else we should be looking at. Our requirements are maximum output we have a 3000sq ft home all valued ceilings two levels, lots of glass, we like the clean lines of the Focus 320, is there another fire insert out there with a larger viewing window that delivers high heat that we should look at before taking the plunge? also any comparisons out there on either of these two mentioned above that would help with our decision making?
