Bradford White Water Heaters.
The next site I visited was the Bradford White water heater site. As with most of the other sites I’ve visited there are a zillion models of water heaters. The site seems easy to navigate and I had no trouble finding the residential products.
If you want to compare water heaters they have a great chart showing the energy factor for all their products including tankless water heaters. The chart makes it very easy to compare the energy efficiency of the various models.
I checked out the service manual for the Bradford White EverHot® Interior Tankless Gas Water Heater Models: IGI-180R-10(N,X) and IGI-180C-5(N,X) Manual 45095A
I must say they have a very extensive service manual. It does a very nice job of explaining how the models work. The theory of operation is very well explained and there are lots of timing diagrams, wiring diagrams, and illustrations. Reading through the service manual is like taking a course in tankless water heaters.
These heaters modulate the gas valve, the number of burners, and the water flow rate to obtain a stable output temperature even with changes in pressure from other appliances or faucets being turned on or off. It’s a technological marvel.
The tankless water heater trouble shooting section is even more impressive. Again, there are no shortage of diagrams illustrations and pictures to guide you. It’s extremely thorough and includes electrical trouble shooting and gas trouble shooting and anything else that can go wrong.
The only thing I found about maintenance was that sometimes you might have to use vinegar to flush the lime buildup out of the heat exchanger. Apparently the heater displays a message when it needs to be done.
Overall I liked the Bradford white site. I found it easy to use and full of useful information in a form that was easy to understand.
That’s if for Bradford White.
