Shipboard Electric Water Heater
6-120 Gallon Capacity, up to 12 KW, Single Phase
The Hubbell Model ME water heater is specifically designed for marine use and is in USCG conformance and IS ABS Type Approved. The entire water heater is securely fastened to the ship structure by utilizing deck and bulkhead mounting supports. This support system provides a secure and reliable water heater installation. To ensure tank longevity the Model ME water heater is constructed of steel and is internally lined with specially formulated hydrastone cement. The hydrastone cement lining, along with the solid copper-silicon threaded tank openings and a built in heat trap device all ensure a longer lasting, energy efficient water heater that is resistant to the higly corrosive effects of hot water.
When you specify and install a model ME, knowing that it is in conformance with USGC regulations and ABS Type Approved, you will have confidence that the ship owner will be provided with a long lasting, trouble-free source for hot water.

Model ME Water Heater Specifications
Standard: 5 Year Non Pro-Rated
Optional: 10 Year Non Pro-Rated
The Hubbell tank is all welded heavy steel construction designed for 100 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.
Factory constructed heavy-duty leg supports are integrally welded to the tank for secure deck mounting. Side-sway bulkhead attachment points are provided for added mounting integrity. This mounting support system provides a stable water heater installation for added mounting integrity. This mounting support system provides a stable water heater installation with improved safety compared to a typical water heater secured with a belly-band
3/4" combination cold water inlet and drain, with non-corrosive strata fow 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 water.
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.
Copper sheathed immersion heating elemtns with low watt density for prolonged life - up to 12 KW in 120, 208, 240, 277, 440 or 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 elemnt configurations are factory wired for non-simultaneous operation.
Highly efficient 2" thick polyurethane foam insulation exceeds the latest ASHRAE standards for nergy efficiency and heat loss
The exterior protective jacket is constructed from high impact composite material which cannot rust or corrode and does not require painting.
