The controll unit makes this unit easy to operate I like the unit very much my problem is that it did not have the Dielectictric fiitings installed as most tanks have when purchased. My other issue is a filter that in most cases will be totally forgotten about the units are getting far to sensative. December 21, 2014
loud but easy to use Having the automated pilot light system is a blessing for a natural gas novice. The heater works well and seems to not run often which is good for efficiency, however when it runs everyone in the house is going to hear the low rumble. Just a little on the noisy side and a solid value. December 7, 2014
