Model CR Specific Questions

How does my water heater ship?

All Hubbell storage type water heaters ship via common carrier and are classified by the Commodity Classification Standards Board under National Motor Freight Classification (NMFC) class 100. Each water heater is palletized and wood crated. All Hubbell tankless water heaters, when transported using common carrier, ship class 77.5. To provide the lowest transportation cost, in most cases the shipment is made on Hubbell’s account and the freight cost is added to the invoice, commonly referred to as “Pre pay and add”. For very large shipments, the most economical method (LTL or Dedicated Truck) for transporting the water heaters to the final destination will be analyzed by Hubbell's transportation department.

Are parts available from the factory?

Yes. All replacement parts for the Hubbell water heater are available from the factory. Please call 800-647-3165 and ask for our parts department. Please have your model and serial number handy. Most parts are in stock and orders placed before noon typically ship same day. However, it should be noted that the heating element component is typically not a stock item, with delivery times ranging from 2 to 10 weeks depending upon the design, it is recommended that you consider having a replacement heating element on hand if your application is critical.

What fluids can I heat with the model CR circulation heater?

The Hubbell CR model circulation heater is commonly used in applications heating industrial process water, potable domestic water, water glycol mixtures, water ethylene glycol mixtures, seawater, demineralized water and RO or DI water. Additional fluids that can be heated by the Hubbell CR circulation heater include oils, sugars and others, please consult a factory sales engineer for details. It should be noted that a Hubbell sales engineer will help to select the appropriate materials of construction and operating features necessary for the proper operation of the model CR circulation heater in your application.

Can it be packaged with a pump, expansion tank or other accessories?

Yes. Hubbell often times integrates pumps and ancillary equipment with a model CR circulation heater to provide a fully packaged and integrated skid system.

Can the heater be used as a boiler or for a space heating application?

Yes, as long as you advise the Hubbell sales engineer and specify this in your quote request. Hubbell builds the CR model circulation heater to either UL1453 (water heating only) under file KSBZ.E239672 or UL834 (boilers and water heating) under file BDJS.E51660. There are slight differences between the two designs, so it is important to know what the application is during the initial quote request phase.

General Questions

Where can I purchase a Hubbell water heater?

There are numerous ways to purchase a Hubbell water heater 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 or our order entry department for quick and easy ordering.

Where can I purchase replacement parts?

I don't see the size or feature I need, what do I do?

Hubbell has more than 35 product families available in over 4,000,000 configurations. There are numerous features, configurations and ratings we provide but for practical reasons are are not listed in the sales brochure. If you have a specific requirement and you do not see it in the brochure, please contact a Hubbell Sales Engineer...chances are we have what you need.

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
