Hubbell Emergency Shower Tepid water Heater



Commercial Electric Water Heater

Provides Tepid Water For Emergency Fixtures

A Heavy Duty, Reliable Source For Tepid Water Delivery

The Model EMV water heater is a packaged system designed to meet the requirements of ANSI/ISEA Z358.1-2014 for tepid water delivery to an emergency drench system. This heavy-duty water heater is constructed of a carbon steel tank and internally lined with 1/2″ thick Hydrastone cement to ensure tank longevity when operating at elevated temperatures, and is fully insulated with 3″thick polyurethane foam to minimize stand-by heat loss. The water heater is packaged with a mixing valve specifically designed, tested and proven for use in emergency safety shower/face/eyewash applications. The entire package including the mixing valve is factory piped and mounted to the water heater to provide single source responsibility.

When you specify and install a Model EMV, you will have the confidence in knowing that the owner will be provided with a long lasting, safe and dependable source of tepid water for their emergency drench system needs.


Packaged with the ESS is a triple-redundant thermostatic valve explicitly designed for emergency safety shower/face/eyewash applications. The HMV  is factory mounted and piped to the water heater. After water flow is activated at the emergency station, the outlet water temperature from the ESS will be maintained at 85°F tepid temperature.

The Emergency Shower Water Heater can achieve the high-volume demand required for a safety drench system by mixing the 70Dc water in the tank with incoming cold water. The mixing valve of our tempered water system meets OSHA and ANSI requirements and can provide constant 29Dc  output regardless of inlet pressure and temperature variations. The temperature is factory set making the valve tamper-proof.

The water temperature is not warm enough to open skin pores and not cold enough to deter usage. The valve can provide a full range of flows from 1.5 LPM for an eyewash to the combined 75 LPM flow for a simultaneous demand for a shower, eyewash, and face wash system.

Safety Features

The EMV incorporates a pressure-sensing controller with a thermal actuator that senses the water pressure on both the hot and cold-water inlet connections. If the hot water pressure is not present, the actuator overrides the mixing valve, and cold water flow is allowed. If no cold-water pressure is available at the mixing valve inlet, the hot water port will close to prevent overheated water from exiting the mixing valve.

The valve also includes a safety override feature that senses the final mixed water temperature continuously. If the final water temperature is overheated, the valve automatically closes the hot water port and fully opens the cold water port. In any of these fault conditions, the ESS will continue to provide a full flow of water as per the ANSI standard with no additional pressure drop.

Typical Applications

The EMV emergency shower water heater packaged with the HUBBELL water mixing valve is used for emergency safety shower and face/eyewash stations in manufacturing, food production, chemical, pharmaceutical, petrochemical, and other facilities where personnel can be exposed to hazardous or corrosive materials.

we offer a range of tepid water systems for safety showers to meet any of your needs. From our steam and water mixing Station, hot and cold-water mixing valve, or our EMV tepid water heater, your employees will always have access to safe, reliable, and comfortable showers when they need them most.
