Bosch ES30M

• Isolated tank design reduces conductive heat loss
• Resistored copper upper element and resistored lifeguard stainless steel lower element to prolong anode rod and tank life
• Premium grade anode rod provides long-lasting tank protection
• Electric junction box located above heating elements for easy installation
• Over-temperature protector cuts off power in excess temperature situations
• Automatic thermostat keeps water at desired temperature
• EverKleen self cleaning device fights harmful sediment build-up with a high-velocity spiraling water stream - helps operating efficiency by saving energy, money and improving tank life
• Enhanced-flow brass drain valve
• Temperature and pressure relief valve included
• 6 years limited tank and component parts warranty

• Transfers heat directly and efficiently to the water, screw-in style
• An exclusively engineered enamel formula that provides superior tank protection from the highly corrosive effects of hot water, this formula (Vitraglas) is fused to the steel surface by firing at a temperature of over 1600 deg F
• Protective magnesium anode rods provides added protection against corrosion for long, trouble-free service
• Factory installed heat traps design incorporates a flexible disk that reduces heat loss in piping and eliminates the potential for noise generation
• Factory installed Hydrojet total performance system
• Durable tamper proof design low restriction brass drain valve
• Non-simultaneous operation, these heaters are wired inter-locking
• 6 or 10 years limited tank and component parts warranty
• Temperature and pressure relief valve included
• Fast acting surface-mount thermostat with high limit energy cut-off (manual reset) for safety
• Non-CFC foam covers the sides and top of the tank, reducing heat loss, this results in less energy consumption, improved efficiencies and jacket rigidity
