What a great experience!! Our water heater went out this morning, Anthony was here by 11:30; new heater installed by 12:30. Everything was professional, friendly, and clean. Anthony explained everything they did -- and everything was perfect. I highly recommend Peninsula Water Heaters. By far the best experience I have ever had with any type of plumbing work.
