Product Details

The Raritan Engineering 1700 Series marine water heater delivers reliable hot water for your galley and shower needs, whether you're docked or underway. This 20-gallon model features both 120V electric heating and an integrated engine heat exchanger, allowing you to generate hot water using shore power or your vessel's engine cooling system.

Key Features:

  • 20-gallon capacity with glass-lined steel tank construction for superior durability and corrosion resistance
  • Dual heating options: 120V electric element plus engine heat exchanger (over 7 feet of coiled tubing for rapid, efficient heating)
  • Dense CFC-free foam insulation provides superior heat retention compared to traditional fiberglass
  • Ignition-protected thermostat factory set to 120°F, adjustable from 110°F to 160°F with 190°F safety shutoff
  • Cylindrical tank design withstands higher pressure than rectangular tanks
  • 75 PSI temperature and pressure relief valve for safety
  • Replaceable magnesium anode rod protects tank and neutralizes water acidity
  • Corrosion-resistant polymer jacket built for harsh marine environments
  • Same-side plumbing connections simplify installation: 3/4" male NPT for hot/cold water, 3/4" female NPT for heat exchanger

Benefits:

  • Hot water availability even when generator power is unavailable—heat exchanger utilizes engine waste heat
  • Retrofits easily to most onboard pressure water systems
  • Glass-lined steel construction offers better longevity than stainless steel in marine applications
  • Hand-assembled and individually tested for quality assurance
  • Backed by 5-year limited warranty on tank, 2-year limited warranty on complete unit

Ideal for cruisers and liveaboards who demand consistent hot water performance in the demanding marine environment. The innovative heat exchanger coil ensures you'll have hot water after extended motoring, while the electric element provides convenience at the dock.

good price

great service

I've been looking for a deal on my parts all over the place for weeks until I came to autoplicity. Even places like ebay couldn't even compare. I saved $40 easily even with shipping and I'm getting the parts quiker then most would ship out. Thank you I will continue to do business here.<br>

Very great to deal with. Phone support is amazing!<br><br>Thanks,<br><br>Chad

Great price and fast shipping

Easy site to use and great prices

Best prices, fast shipping, and product as described. I would definitely recommend Autoplicity.

Customer service was great. FEDEX Freight had damaged my order and they sent another one. I have no complaints and will do buisiness again with Autoplicity.

So far so good

Great prices, helpful customer service. Ordered 2 by mistake. And they got it cleared up real fast. Saved over $80 off retail. Will be ordering from the, again!!!!! <br>

Very good

Hands down the best price on the Magnaflow catback I have seen by more than 20%. They were able to work out the ship-from-manufacturer tracking after a quick phone call. Will definately be recommending these guys to others.

I shopped around a little first and Autoplicity had the best price on a wideband sensor and gauge. When I needed a fuel pressure regulator too, I found their price was the best so I ordered both from them. Great prices and fast deliver!
