Model MSE

Shipboard Electric Water Heater

6-119 Gallon Capacity, up to 58 KW, Single or Three Phase

The Hubbell Model MSE water heater is specifically designed for marine use and is in conformance with USCG and is ABS Type Approved. By utilizing deck and removable bulkhead mounting supports, the water heater is securely fastened to the ship structure, thus providing a secure and reliable water heater installation. To ensure tank longevity, the high quality tank is constructed of steel and internally lined with specially formulated hydrastone cement. The Hydrastone Cement lining, along with 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 highly corrosive effects of hot water.

When you specify and install a Hubbell model MSE, knowing that it is in conformance with USCG 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 MSE Specific Questions

Is a glass lined tank recommended for marine use?

Not in a commercial marine environment. The real cost of a water heater in a marine environment, especially commercial marine, is the cost of replacement. Therefore, it makes economic sense to install a water heater with a long life expectancy. Hence, glass lined water heaters are not the best choice in a marine environment when a cement lined water heater can typically provide 3 times longer life in comparison.

Which is better for me, a tankless or storage type water heater?

It depends. A tankless water heater is sometimes referred to as a Point-of-Use (POU) or instantaneous water heater. Due to the relative small physical size of a tankless water heater compared to a storage tank water heater, a tankless option can be advantageous from a space saving perspective and can sometimes be installed closer to where you want hot water (hence the term POU). However, tankless heaters are not suited for many applications, so it is critical that before choosing to go tankless you have carefully considered all of the factors that sometimes make the tankless option more complicated and risky compared to a storage type water heater. In particular, you should understand the operational characteristics, maintenance requirements, reparability, and sometimes significant installation requirements of a tankless water heater before making a decision. Tankless units do not store heated water like a storage type water heater; they only heat water as there is demand and therefore must be sized to meet the maximum flow for the application. In some cases a tankless water heater may improve operating efficiency, but possibly at the expense of user comfort. Hubbell tankless water heaters are available in Electric Tankless or Gas Tankless. Watch our video on tankless vs storage.

Why is Hydrastone Cement a better choice over glass lining?

Cement lining provides guaranteed 100% coverage with a minimum thickness of 0.5” over all internal tank surfaces. In comparison, glass lining is approximately 0.005” thick and includes imperfections, pinholes and variation in coverage thickness resulting in portions of unprotected steel tank exposed to corrosion. In an attempt to compensate, glass lined tanks include a sacrificial anode in an effort to slow down the corrosion of the tank. Cement lined tanks on the other hand do not require an anode due to the integrity of the lining. As such, a cement lined tank will far outlast a glass lined tank. For a more complete explanation of the benefits of the Hubbell cement lining please click on the following link Cement Lining

Is American Bureau of Shipping (ABS) approval needed?

Equipment and specifically water heaters for use in commercial marine applications require special construction features to ensure longevity and proper operation in a marine environment. In addition, the water heater must be constructed in conformance to the Code of Federal Regulations USCG 46 CFR Part 53.01 and the pressure vessel must be designed and constructed to the proper ASME code and stamped. A Hubbell marine water heater is manufactured under a Certificate of Manufacturing Assessment as issued by American Bureau of Shipping (ABS) Here

What is a sacrificial anode and does a cement lined tank need one?

All water heaters constructed using a steel tank requires a lining to protect the internal steel surfaces from corrosion. Certain linings (i.e. glass and epoxy), due to their nature, have unavoidable holes and imperfections resulting in exposure of the steel tank. As a result of this deficiency, the manufacturer will install an anode rod(s) in an attempt to delay corrosion of the steel tank. An anode rod is typically made of aluminum, magnesium or zinc, is a maintenance item that requires periodic inspection and replacement, and is often times the cause of a “rotten egg” odor to your hot water. Often referred to as a sacrificial anode rod because, over time, it slowly dissolves, sacrificing itself as it is attacked by aggressive substances in the water which would otherwise attack the steel tank through the pinholes and imperfections of the glass or epoxy lining. A cement lined steel tank on the other hand does not require an anode because of the thickness and guaranteed 100% coverage of the cement lining over all internal surfaces of the steel tank. This eliminates the need for an anode rod in a cement lined water heater, resulting in a significantly longer life compared to a glass or epoxy lined water heater.

What should I know about Legionella disease?

Legionella is the bacteria responsible for Legionnaire’s Disease, an acute bacterial infection of the lower respiratory tract. This bacterium was first identified in 1977 by the Centers for Disease Control as the cause of an outbreak of pneumonia that caused 34 deaths at a 1976 American Legion Convention in Philadelphia. Pontiac Fever is a less severe, non-pneumonia, flu-like disease that is associated with and likely caused by Legionella bacteria. Legionella is a fairly common water bacterium and has been found to exist widely in many surface water sources including lakes, rivers, streams and ponds. It can also be found in ground water sources and some soils. At the levels found in these naturally occurring sources it typically does not pose a threat to public health. When the bacterium enters a domestic water system it can find an ideal host environment of warm water temperatures (105-115°F), stagnant water areas (isolated storage tanks and dead-end piping legs) and ample food sources (sediment, scale, deposits and biofilm). Under these conditions Legionella can rapidly colonize, forming higher concentrations that can pose the public health threat of Legionnaire’s Disease. There are many methods of controlling colonization of Legionella bacteria. However, a widely accepted and preferred method is to maintain the hot water system storage temperature continually at or above 140°F. Unfortunately, the elevated temperature necessary to minimize the growth of and kill Legionella bacteria has the potential to cause serious thermal shock and scalding injuries. As such, many plumbing engineers will specify that the water heater be set to maintain water temperatures at 140°F or higher to reduce the risk of Legionella, but then specify the appropriate mixing valve to ensure safe delivery of hot water to the fixtures. For a more thorough discussion of Legionella please go to here and the following link to the US Department of Labor OSHA information regarding Legionnaires’ Disease OSHA here
