High Performance and High Efficiency

The S-Series electric water heater from Vaughn Thermal combines time proven technologies with our Hydrastone Cement lining for the industry's longest lasting and most reliable high efficiency water heater. The Vaughn S-Series electric water heaters are equipped with low watt density elements, thereby reducing the potential problem of mineral build up common to the failure of conventional elements. A cleverly designed cold water inlet connection gently diffuses the flow of cold water in the lower portion of the tank, resulting in improved energy efficiency and performance. The S-Series is available in a wide range of sizes, making it a versatile fit for any project. Lowest standby heat loss, proven components and the industry's longest lasting tank make the S-Series electric water heater the preferred choice for your water heating needs.

S Series

Heavy Duty Construction

  • Seamless Hydrastone cement lining provides long tank life
  • Plastic jacket will not rust, scratch or dent eliminating damage and is maintenance free

High Efficiency

  • 2" thick polyurethane foam insulation reduces standby heat loss to maximize operating efficiency

Advanced Heating Element

  • Low watt density element and all copper/brass construction provides protection against mineral build up

No Sacrificial Anode Rod

  • Reduces operation expenses by eliminating periodic inspection and replacement costs associated with maintaining an anode rod

Radiant and Space Heating Certified in the USA and Canada

Warranty

  • Industry leading 10 year tank warranty and 1 year limited parts warranty

General Specifications

Tank

The Vaughn tank is all welded heavy steel construction designed for 150 psi working pressure and tested to 300 psi. Each tank is centrifugally lined with 1/2" thick seamless high density Hydrastone cement with guaranteed 100% coverage of all steel surfaces. All tank openings are non-ferrous solid copper-silicon and are resistant to the corrosive effects of hot water.

Plumbing

3/4" combination cold water inlet and drain, with non-corrosive strata flow diffuser which prevents incoming cold water from mixing too rapidly with the hot water in the tank and assures delivery of more hot water - not lukewarm. A 3/4" hot water outlet with a uniquely designed built-in heat trap prevents heated water from radiating through the piping during standby periods.

Electrical

Copper sheathed immersion heating elements with low watt density for prolonged life - up to 12 KW in 120, 208, 240, 277, 480 volt single phase. An adjustable surface thermostat operates in 110-170°F range.
Integral hi-limit with manual reset button for over-temperature protection is factory set at 190°F.
Upper and lower element configurations are factory wired for non-simultaneous operation.

Insulation

Highly efficient thick polyurethane foam insulation meets or exceed the requirements of ANSI/ASHRAE/IESNA 90.1-2007 standards for energy efficiency and heat loss.

Jacket

The exterior protective jacket is constructed from high impact composite material which cannot rust or corrode and does not require painting.
