900 sq ft home heated in 7 minutes!

I noticed that there are two sides to all the reviews, half say they are lousy, which many of them was an easy sensor to clean and complained about noise! The other half which I belong to, cleaned the sensor about once every 3 years on avg, and for me, I know the noise of the fan blower is good, it means hot air is flowing baby! If you buy anything but a Rheem, you will feel like you got reemed.
