What temperature should I set my water heater?
For typical domestic potable hot water service the temperature of your water heater at 125°F is sufficient. This prevents wasted energy (which means cost savings for you) and also decreases the possibility of scalding water burns. If you run out of hot water on this setting, increase the temperature by five degrees incrementally until your hot water needs are met. The goal is to have the temperature set just high enough to meet your needs but within safe operating parameters. Please note that a water heater in and of itself should not be relied upon as the ultimate temperature controlling source for the hot water delivered to your fixtures. Please consult local and state codes for installation of the proper and code approved (ASSE 1016, 1070, 1017) mixing devices to achieve the safe delivery of hot water to the fixtures.

What is the average life of an electric water heater?
The most important factor related to the life expectancy of a water heater is the quality and type of storage tank. On an average the life expectancy of a glass lined electric water heater is about 10-12 years (according to the National Association of Home Builders 2007 Study of Life Expectancy of Home Components http://www.nahb.org/fileUpload_details.aspx?contentID=99359 ), compared to a cement lined electric water heater’s average life expectancy of 23-26 years (Independent study of over 25,000 installations for an Electric Utility). Of course, there are various other factors that affect longevity including pressure fluctuations, usage, water conditions, environmental conditions, etc.
What is thermal expansion and how does it affect me?
Thermal expansion is created when water in a hot water system expands due to increasing temperature. When there are no faucets/fixtures open to release the excessive pressure caused by the water being heated up, and if there is no expansion tank in the system to absorb the expanded water, then it is likely that the water heater T&P (temperature and pressure) relief valve will open slightly and begin to drip to release the excessive pressure. This is not a condition that the T&P relief valve is intended, it is a safety device not an operational device. Thermal expansion can be evident immediately upon a new installation when a cold system is first undergoing heat up, or even occur years in the future due to seemingly unrelated changes to the plumbing system but enough so that thermal expansion becomes a problem. If Thermal expansion is present a properly sized expansion tank should be installed to resolve this problem.
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 Electric Tankless or gas Gas Tankless
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
Why is the T&P valve tested to ASME standards (as opposed to CSA/AGA)?
The Hubbell water heater is built to and approved by UL to ANSI/UL 174 and CAN/CSA-C22.2 No. 110 (1990). These standards require that each assembled water heater be shipped with a factory installed combination temperature and pressure relief valve sized in accordance with ASME requirements. However, if a relief valve sized to CSA/AGA is required, you must indicate this at time of requesting a quote for your water heater as this may necessitate a larger opening in the tank to accommodate a larger CSA/AGA relief valve.
My T&P relief valve is dripping water, what does this mean?
A temperature and pressure (T&P) relief valve is a safety device intended to relieve excessive pressure (typically >150psi) or excessive temperature (210°F/99°C). Typically, a dripping T&P is most likely the result of excessive pressure build up in the water heater. When a T&P opens due to excessive temperature, you will most likely see a significant amount of steam in the air as the water flashes into steam as it discharges from the T&P. A relief valve discharging due to excessive pressure is by far the most common reason for relief valve discharge. It is also worth noting that a T&P relief valve will begin to open when pressure is within 5% of its set pressure rating, as an example a 150psi relief valve will begin to open and “weep” at 142psi. See FAQ relating to thermal expansion for a more detailed discussion of this problem.
Where can I purchase a Hubbell water heater?
There are numerous ways to purchase a Hubbell water heater, mainly depending upon the model you desire and your geographic location. The easiest way is to contact Hubbell directly at 800-647-3165 and ask for the sales department where you will be directed to either our local representative, local wholesaler or dealer, internet or our own order entry department for quick and easy ordering.
What code requirements are applicable for my installation?
The installation of water heaters are mostly governed by the Uniform Plumbing Code (or CPC in California), Uniform Mechanical Code, and National Electrical Code. These are standard codes that are used across the United States, and each state can amend them as they wish. To take it further, each city and county jurisdiction has assigned one or more building officials with what is called Administrative Authority. This "Authority" allows each jurisdiction the right to interpret the codes as they see fit. Because of this, many cities differ on their requirements. Hubbell strongly recommends that you contract with a plumbing engineer who knows and understands the intricacies of the building code requirements for your location.
Do I really need to install a T&P relief valve?
Yes. Even though the CE110 has minimal storage (1 gallon) and is considered a Point-of-Use heater, it still requires the installation of a combination temperature & pressure (T&P) relief valve.
Can I serve more than one hand washing fixture from the CE110?
Yes. The CE110 can be installed to service two (2) hand lavs, but will likely require the optional mixing valve in order to supply sufficient hot water to both fixtures. In this type of installation the CE110 would be set to a hotter temperature (as an example 140°F) and the mixing valve would be installed in the plumbing to mix 140°F water from the CE110 with cold water to supply safe and reliable hot water temperature (as an example 110°F) to the fixture.
Why not use a tankless heater instead of the CE110?
Both the Hubbell model CE110 and electric tankless water heaters can be considered Point-of-Use (POU) designs that work well serving hand washing lav sinks and other small demand applications. Both designs are compact and can be installed close to where you want hot water (hence the term POU). One major difference between the two is that a CE110 always needs a T&P relief valve, whereas a tankless heater may or may not depending on local code. The other major differentiating feature between the two is power consumption. The CE110 is 120v and draws either 8.3 or 3.7 amps depending upon the wattage selected (1000w or 450w). Tankless heaters do not store heated water like the CE110; they only heat water as there is demand and therefore must be sized to meet the maximum flow for the application. A tankless heater therefore will require significantly more wattage to service the same application. As a comparative example a tankless heater would have to be 5.5kw to provide 0.5GPM at a 75°F rise (drawing 23 amps at 240v) to service a single lav sink, and you would need to double the size to serve two lavs, compared to installing one Hubbell model CE110 with mixing valve to serve both lavs with only 1000w 120v 8.3 amp power. Finally, it should be noted that many tankless heaters are not temperature controlled; the temperature fluctuates based upon the cold water temperature and flow of the fixture and many times require a flow restrictor or replacement aerator to be used to restrict the flow rate. The CE110 on the other hand is a temperature controlled water heater does not restrict flow in any way, which provides a more consistent and user enjoyable hand washing experience. If the tankless option is right for your application see Hubbell’s complete line of electric tankless heaters at Here
Is the warranty ten (10) years for the entire CE110 model?
Yes. The warranty covers the entire model CE110 including the operating controls (electric element, thermostat and hi-limit). The only item not covered is the T&P relief valve.
When to use the 450 watt model instead of the 1000 watt model?
When serving a single low use fixture often times you may be able to use the 450 watt model. For applications serving more than one fixture we recommend the 1000 watt model.
Can I get the CE110 in voltages other than 120v?
For specialized applications we do have versions of the Model CE110 in alternate single phase voltages (208v, 240v and 277v). Please contact the factory for details.
