Bradford White takes a different approach – you can’t buy their water heaters at big box stores. Everything gets sold through professional plumbers who know how to install them properly. Made in Michigan, these units support American workers and use domestic materials.
Safety matters with gas appliances, and their Defender System prevents dangerous vapor ignition better than anyone else. Businesses and contractors choose Bradford White because downtime isn’t an option for them. If your water is hard or your mechanical room is cramped, these units handle it.
