20-Gallon Hot Water Heater with Heat Exchanger - 4500w/240v

The "1700 Series" water heater provides hot water for galley and shower. Dense foam insulation provides better and longer heat retention than traditional fiberglass. The tank itself is protected by a 75 PSI T& P (temperature and 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 when underway or generator power is not available. The innovative heat exchanger is over seven feet in length and is evenly coiled throughout the interior of the tank, providing hot water rapidly and efficiently.

Raritan's water heaters use an ignition protected thermostat. Although it is factory set to 120°F, it is adjustable from 110° to 160°F and has a safety shut down limit of 190°F. All models and sizes have the plumbing connections on the same side to simplify installation. Hot and cold water connections are 3/4" male NPT (National Pipe Thread). Heat exchanger connections are 3/4" female NPT.

Love this!
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
This toothpaste does not foam but my mouth has never felt cleaner or fresher! The taste is minty fresh and I have noticed a difference in the whiteness of my teeth since I started using it! Very effective and I highly recommend!

Baking soda never works out well
Flavor Name: 1. Sensitive Mint, Size: 4 Ounce (Pack of 1)
I don't know why I decided to chance it but it didn't take long for my teeth to start aching. I realized baking soda might be the cause of my toothache issues when I switched between a few and realized the baking soda ones were accompanied by aching. I think I went with this because it claims to be for sensitivity and I thought the nhap would help whatever the baking soda affected but not the case. If you have tooth ache, consider it might actually be the toothpaste and don't just go looking for "sensitive" labels. This might work in combination with other toothpaste. I.e. not multiple times a day but once a day and a different one for other brushing. I've noticed not being as able to tell when it's been a while since I brushed. This was the main change so it might be effective at cleaning. The tube is metal and hard to press but the paste consistency is less firm than others so it works out. It didn't take much to get the paste out. It gives a light foam. The taste is not sweet. It's tolerable but borders on bad.

Good for exfoliating
Color: Beige (4 Packs)
These are great for saving and using soap slivers. I can't stand to throw out something useful but once they get too small they're hard to hold onto. I had a mesh bag but it started to come apart and I thought these would hold up better. These bags are thick and sturdy. They're a little stiff at first but softened up quickly. They're great for exfoliating. The only change I would like to see is the wood closing bead changed to a locking clip as it slides open all the time.

Great product!
Color: Beige (8 Packs)
I buy handmade soap from a local soap maker, but I’ve always had trouble with it lasting—if I leave it in a soap dish, it never dries properly and melts away too quickly. I used to use loofah socks, but they were frustrating: the knots wouldn’t stay tied and they tore apart easily. I decided to give these a try, and I’m impressed! I had a couple of concerns going in. First, I wasn’t sure they’d fit the larger-sized handmade bars I use—but they do! It’s a snug fit at first, which can make lathering a bit tricky, but after one or two uses it softens up and starts to lather beautifully—honestly, better than the mesh loofahs I’ve used. The design is thoughtful: the knot stays secure, and the bead keeps the soap from slipping out—both huge improvements over other products I’ve tried. The biggest surprise? The exfoliation. It’s effective without being harsh, even on sensitive areas. My skin felt softer than it ever did with sugar or salt scrubs. That’s an unexpected bonus I didn’t even realize I needed! Highly recommend—especially if you’re using handmade or natural soaps and want to make them last longer.
