General Specifications

Tank

The Hubbell 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.

Notes:
All 3 phase open delta water heaters are supplied with upper and lower heating elements that are wired for simultaneous operation. Due to the unbalanced load of a three phase open delta circuit, the amperage on one leg is higher. Circuit protection should be sized based on the amperage of the highest leg of the open delta (L3).

Model E Specific Questions

Can a timer be installed on my Hubbell water heater?

Water heater timers are devices that provide automatic control of electric water heaters. They can be programmed to turn a water heater off or on at times typically set by your local utility. Your local electric utility may have in place an “Off-Peak” or Time-of-Use (TOU) rates which offer a customer the incentive to consume power during certain periods of the day. The Hubbell Model E is available with various timer control options, ranging from programmable 7 day timers to utility specific devices that control the water heater.

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

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. For a further discussion please click on the following link Cement Lining

What does 3 phase Open Delta wiring mean to me?

Without getting into a lengthy discourse on electricity, the simple answer is that any water heater internally wired in a 3 phase open delta configuration is unbalanced, meaning that the amperage drawn by one of the three legs is high and unequal to the other two legs. This unbalanced water heater can have a detrimental effect on a buildings power system and therefore needs to be carefully understood before you install a water heater configured for 3 phase open delta. It should be noted that the branch circuit protection (i.e. circuit breaker) servicing a 3 phase open delta water heater needs to be sized for the high amperage leg. The Hubbell model E is available up to a maximum of 12kw in 3 phase open delta wiring. Alternatively, the Hubbell model SE is a balanced 3 phase water heater, meaning that all three legs draw equal amperage. The Model SE is available up to 58kw click here details Model SE

Why is there an upper and a lower heating element in my tank?

Hubbell Model E water heaters with 30 gallon storage or more have both upper and lower heating elements in the tank, and models 20 gallon storage and less have one heating element in the tank. The purpose of having two heating elements in a tank is to improve the recovery rating in a water heater of significant storage capacity. Sometimes referred to as a “Quick Recovery” water heater, this configuration allows the upper element to heat a much smaller volume of water (about 25% of the tank's capacity) before the lower element takes over. This provides a small amount of usable hot water quickly while you wait for the bulk of the water to heat. It is worth noting that in the standard dual element design, the upper and lower heating elements are interlocked so that only one can heat at any time, with priority to the upper element. Once the thermostat controlling the upper element is satisfied (i.e. at set point temperature) the lower element is allowed to heat. As an option, you may order your Hubbell water heater with the optional “simultaneous operation” feature which allows each element to operate independently, potentially allowing both to be on at the same time in order to increase the recovery rate of the 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
