Most fireplaces are about the same. The Portrait series which is actually our smallest fireplace probably gets the best numbers by a couple of points. It is not significant, but it would be the most efficient of the range. One of the things that we point out is that the energy efficiency standards don't really recognize the benefit of radiant heat. The radiant aspect is a bonus that that doesn't really get reflected in the numbers. There are a couple of standards currently being used by the approval agencies to detect energy efficiency. There is the American standard and there is a new Canadian one referred to as P4. The new P4 standard is probably the most comprehensive and so far, it seems to be the best testing that's been done on fireplaces to date.
