Yes. Sediment creates a thick layer of insulation between the burner and the water. The burner has to run longer and hotter to heat the water, which overheats and weakens the steel tank bottom, eventually causing it to fracture.

Most new standard tanks come with a 6 to 10-year manufacturer warranty on the tank and parts. Tankless systems often feature up to a 12-year warranty on the heat exchanger. We also back our installations with a labor guarantee.
