Would be a significant increase in heat output. The "whisper mode" would be nice too.Actually my 2010 Quad Santa Fe is only rated up to 30,000 btu/hr. And rated for 1500 square feet. The new ones seem to have more output and square footage. So with the Harman I would be going up to 44,000 and 2400 square feet. So it would be a step up from my 2010 model.
