I have a Bosh AquaStar 170V. My family has grown since we put in that tank. It does ok but we could use more GPM now. My old unit has a pilot and was about 80% efficient not too bad. It also does not keep the water at as a steady temp as the new electronic controlled tanks.
The attic install was a mistake. It has a couple 60 watt bulbs that have to keep it warm in the cold winter. They are temp controlled to turn on and off but if the burn out it will freeze the hot water. This is just a bad setup and I am going to change this.
