A:  Hello, the depth of this unit is 33 inches. The remaining questions would be better suited for the vendor, Westinghouse. Please contact them at: 1 (866) 442-7873.

A:  Hello Jerome, The difference between this unit is the gas type. This unit is natural gas and the other unit is liquid propane. Thank you, Westinghouse Water Heating

A:  120v

A:  the unit is gas but it also needs a 120 volt 15 amp circuit to power the fan and controls.

A:  Per our local PA plumbers it is REQUIRED to be vented out a side wall. Regulations in your area may differ. You cannot vent through the house flu anymore. It has to be at least 14 inches off the ground and 4ft from any window. This makes doing a hot water heater swap far more complicated that it use to be.

A:  Mine is vented out a side wall, so yes it can be vented that way. My vent is at about the same height as the top of the heater; I don't know if venting to a lower point would work. The unit has a fan, so maybe lower vent would work, but I don't know. You should be aware that these high efficiency heaters have very different installation requirements than a regular heater: They have a condensate drain that has some sort of chemicals in it, which normal heaters do not have; plus the regular metal flue will not work -- have to have PVC. This makes installation much more expensive, i think I paid $3,000. My heater had a defective valve, which was replaced by the manufacturer, but which meant the installer had to come back a number of times. You should also be aware that installers are not very familiar with these high efficiency heaters and you may have difficulty finding one who can do it. Once installed and repaired, however, the heater has been working perfectly for about 8 months. If you are in California, this heater will qualify for a rebate under the state's energy program, but only if you install other high efficiency things at the same time, primarily a high efficiency furnace.
