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

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.

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.

Yes. Please consult with your Hubbell Sales Engineer.

If your marine application demands the longest life and most reliable operation, then you should consider a solid copper alloy tank for your water heater. This type of tank is constructed from 90/10 copper nickel (or copper silicon 655) alloy for maximum longevity. This copper alloy is highly corrosion resistant even at elevated water temperature and has the most desirable characteristics for use as a water heater tank. This construction is intended to last the life of your ship, and as a result is likely to have the lowest total cost of ownership over th life of the ship when one considers the tremendous cost for removing and replacing a lined steel water heater. Ship owners know all too well the real cost involved of cutting out and replacing equipment. Therefore, the owner motivated to provide the lowest total cost of ownership water heater will benefit when the onboard water heater is specified as copper alloy.

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.
