Who has one ?? Likes / Dislikes ? How long do you wait for hot water ? I need to upgrade my water heater this summer (2 teens......... long showers = no water left for me !) Any brands to stay away from ? Im looking for a electronic ignition model with no standing pilot. Need a size recommendation for a 2 1/2 bath house, for use where 2 showers will be on at the same time. Thanks in advance !
