Raritan Water Heaters provide hot water for galleys and showers. Dense foaminsulation provides better and longer heat retention than traditional fiberglass. The tank itself is protected by a 75 PSI T&P (temperatureand pressure) relief valve. The cylindrical design of the tank enables it to withstand more pressure than a cube shaped tank. Heat exchanger models can be connected to the engine cooling system. This provides the added convenience of hot water underway or when generator power is not available.

I have a serial # em7440101. When was this heater made?
Not a clue .... try going to Raritan Engineering directly (raritaneng DOT com) and asking them.
Where on the unit is the adjustment for the water temp?
Unfortunately, the PDF does not want to download. There is no obvious knob, etc, on the water heater to turn the water temp up or down, which to my way of thinking is a poor way to design such a device.
Please send me an email and I'll send you the PDF file.
See Fig. 2 in the owners manual for the location of the temperature adjustment.< a href="http://www.raritaneng.com/wp-content/uploads/2011/08/L206v0909-1700-Series-Water-Heater-Manual.pdf" target="_blank">http://www.raritaneng.com/wp-content/uploads/2011/08/L206v0909-1700-Series-Water-Heater-Manual.pdf< /a>Looks like the adjustment screw is just below the reset button.
for those of you who replaced an old water heater....what was wrong with the old one! Mine is not currently working, and I was thinking it has to be the thermostat or heating element...what else can go wrong?
The old heaters get full of sediment and then the elements burn out. Some burn out from age or lack of water. Thermostats can burn out over time too. If its over 10 years old i would replace it.
Raymond,Thanks but I think I'll try a new thermostat and element before sinking $700+ if I don't have to.Mike
will this rust on in the boat?
I don't think so. The tank is encased in foam. My previous Raritan only lasted about thirty years.
The water heater can rust in the boat. I'm currentlyreplacing one because of rust. It's important that theheater either be placed in a location without access to water OR, perhaps fastened down over some "risers" to prevent any present water from contacting the steel bottom cover of the heater.
Repacing the R-6 (older Raritan 6 gallon water heater with heat exchanger) on my sailboat. The R-6 is 14 inches across and I have to squeeze it through the lazaretter opening. The new one is advertised as being 14.5, which won't fit. Is it really 14.5 or is that allowing for some safety margin?What is the exact measurement, and how does taht bottom mounting work? Does it come off? Or is THAT teh 14.5 measurement?
First Name Last Name
The 14.5" width refers to the actual unit. The base (flange) is 16.5" wide. I don't know if they have changed their design over the years, but I would recommend you contact Raritan directly to discuss this further. The base flange can be screwed to a deck for the 6 gallon model.
I have a 48 ft Offshore Sedan built in 1997 . The existing Hot water heater uses the heat produced by the engine or the electrical . It is a 14 gallon tank . Is there any reason to believe that this on would not work on my boat ?
Steve,I use the Raritan 12 gallon in my 1983 Newell RV. The original Raritan unit lasted from 1983 to 2011. By the way, my RV gets a lot of use. I have used it full time for the last 3 years. Before that my usage ranged from full time in 1998 and 1999 to between 3 and 10 months annual use from 2000 to 2008. My original unit included the heat exchanger. I decided to give that benefit up on the replacement (installed 11/2011). IMO this is a great product. If the measurements and clearances work for you I would recommend this product. Will you be OK going from a 14 gallon to a 12 gallon?Art
It will work just fine. Raritan produces an excellent product. The hook up is simple and the enclosed instructions are more than adequate. If you haul your boat for the winter and you winterize make sure you plumb in a drain valve on the cold water inlet as there is no drain on the tank itself. There are also kits for winterizing hot water tanks if you use RV antifreeze (pink stuff) so you don't have to fill the hot water tank.
Raritan Water Heaters easy to replace
Be sure have all necessary fitting before doing instalation. Barbed fitting that fit into the entry and exit holes for the water and presure release.
