1 Gallon Point-of-Use Electric Water Heater

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.

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 inElectric Tankless or Gas Tankless.

Why is the T&P valve tested to ASME standards (as opposed to CSA)?

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 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 relief valve. For reference, please see the following link to an article on this subject Here

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.

Which NSF Standard is appropriate for this product?

The appropriate NSF Standard to use is NSF 5, titled “Water Heaters, Hot Water Supply Boilers, and Heat Recovery Equipment”. In the past the lead content requirement was only required in NSF 61 per Appendix G, but within the past few years changes have been made such that Appendix G has been removed and replaced by NSF 372, “Drinking Water System Components – Lead Content”. NSF 5 requires materials approved by NSF 51, “Food Equipment Materials” and the latest edition of NSF 51 requires that the materials comply with NSF 372. Therefore, NSF 5 now complies with the same low lead requirements as NSF 61.

Can the CE110 mount under a lav and is it ADA compliant?

Yes. The small compact size of the CE110 makes it a perfect fit for installation under a lav where it can be installed in compliance with ADA requirements.

Is this model approved by Massachusetts?

Can my heater ship via UPS?

Yes. Hubbell packages and ships this model water heater via United Parcel Service (UPS).

Do Hubbell water heaters qualify as Low Lead?

Yes, all Hubbell water heater models qualify as meeting the low lead requirements of the “Reduction of Lead in Drinking Water Act” amendment to the “Safe Drinking Water Act” (SDWA) Section 1417(d) effective as of January 4, 2014. Hubbell certifies that its water heaters meet the following requirements of the SDWA and therefore are qualified and certified as Low Lead : (a)Hubbell water heater do not contain more than 0.2 percent lead with respect to solder and flux (b)Hubbell water heaters do not contain more than a weighted average of 0.25 percent lead with respect to all wetted surfaces of the water heater

What is the difference between solid-state and electromechanical relays?

Depending on the application, one switch may be more advantageous than the other. Please refer to this article to read more about the differences between solid-state and electromechanical relays.
