My water heater is on its last legs and today I called the plumber I usually use to get a price to replace it. They install Lochinvar water heaters. I have never heard of that brand. He quoted me a price for a 50 gallon, 6 year, propane water heater. Now I'm torn between letting him install Lochinvar or finding a plumber that I've never used before that installs Bradford White water heaters. Bradford White was really what I wanted. Is it worth the effort to change plumbers for this job or is Lochinvar a good water heater? Thanks for your help!
