Rated 5 out of 5 by from What a tank! Ok, so after my 2nd standard 80gal tank popped, and I was quoted a price for a standard steel electric that was nuts, I started my research into the Rheem Marathon 105 and thought about how many times am I going to need to replace my tank again over the next 30+ years (3-4x). I landed on the 105gal because of 4 regular occupants of the house and lots of guests over. On arrival the tank was big in its box. Towering at over 6 feet high and 2 ½ feet wide...you need 2 people and a dolly to get in. Removing the old tank was a pain...installing the Rheem w.asn't too bad. Here are some hints to keep your frustrations down and to plan ahead. 1. Requires 30amp electrical with 10/2 wiring. Make sure you look at how your existing is wired and look for red sheathed wire. If you don't have 10/2, call an electrician in. 2. Highly suggest installing on a timer so get the best power rates, I have been using an Intermatic Electronic Water Heater Timer 240V 30A 7200W DPST which lowers operating costs a lot. 3. The hot water outlet requires a 1" brass nipple 4. Don't just use tape, apply leak seal as well 5. DO NOT allow the pre installed fittings to move when making your connections and snugging up. Get help if needed with another wrench to hold the tank fitting in place while you tighten up. 6. The PRV should have a 3/4" x 12" brass nipple installed with a 3/4" FIP x copper sweat, and then continue down with 3/4" type M copper. Don't cheap out here. But make sure you get past the side of the tank. 7. Once installed, expect it to take about 5hrs to heat up for the first time...then enjoy. 8. One more thing.....there is going to be air in both your hot and cold lines....bleed everything! And if you're curious what the pump is...thats a Grundfos MQ3-45 helping water pushing thru the house and the tank works well with it So far it has been amazing. I haven't had a cool shower since installing.

Our electrical system only has 208V available. Will this water heater operate properly on this voltage?

Does this come with Brass fittings on top of the tank? Or Plastic?
