Most leading water heaters are lined with porcelain-enamel glass. Tiny pinholes (holidays) in this material expose the steel tank to water, leaving it vulnerable to corrosion. To protect the tank, a "sacrificial" anode rod is installed to corrode first. If the rod is not replaced regularly, the whole water heater will need to be replaced.
Vaughn tanks flip the script
Our HydraStone cement lining provides full seamless coverage at a minimum of 1/2 inch thickness, 100 times thicker than glass. With no tiny pinholes (holidays) it outperforms glass and epoxy in all water types— with no anode rod needed.
Cement lined tanks offer significant longevity, trouble-free operation and a lower lifetime cost. The tank's protective lining is the deciding factor for water heater quality. Hubbell Heaters HydraStone cement lining provides complete, reliable coverage. The lining's ability to protect the steel tank depends primarily on its thickness and full surface coverage. A glass lined tank uses only 5/1000 inches of glass (the thickness of a sheet of paper) and does not cover all internal surfaces. To compensate, all glass lined tanks require a sacrificial anode rod, which must be inspected and replaced regularly. Our tanks are lined with a minimum of ½ inch of high density HydraStone cement — 100 times thicker than glass lining. We achieve full tank coverage by injecting HydraStone cement into each tank and centrifugally spinning it at 250 RPM. This process provides maximum protection from the corrosive effects of hot water. Since cement lined tanks do not require a sacrificial anode, this eliminates the periodic inspections and replacement costs associated with glass lined tanks. Our water heater tanks are constructed with solid non-ferrous copper-silicon tank tappings, impervious to the corrosive effects of hot water. Glass-lined tanks have steel tappings, vulnerable to corrosion. Choose longevity. Choose a HydraStone cement-lined water heater.
Our Featherweight units deliver lasting performance with less bulk. Thermoplastic lining provides guaranteed 100% coverage with a minimum thickness of 0.125” Thermoplastic over all internal tank surfaces.
Contractors know the struggle of wrestling heavy units into tight spaces. For easy-breezy installs—Vaughn Featherweight Thermoplastic (FW Series) water heaters. Ultra-light construction under 150 lbs and top-mount connections make installs no sweat. Each Vaughn FW tank passes accelerated testing that simulates over 40 years of use. The thermoplastic lining provides full interior coverage at a minimum 0.125-inch thickness, 25 times thicker than glass. This means no need for an anode rod, a part that requires regular replacement. Built from polybutene and polypropylene material, the FW tank resists corrosion and stays water-quality neutral. Our Featherweight units deliver lasting performance with less bulk. Available in our PF Indirect, MP Electric, VG-MP V-Grid enabled, CP Aqua Booster storage, and HP Heat Pump (hybrid) water heaters.
