I have a Rheem which is the same as a Rudd and Paloma... at least it was when I purchased mine. I have had it almost 3 years with no problems. I would put the Rheem, Rannai and Takagi as comparable units, with some specific things that may recommend one over the other - such as one brand might have a size that is a closer match to what you need, for example. I would stay away from Bosch units. They made a disastrous Aquastar unit and that taints my perception of their entire line. The Navien is a little different, in that it uses a stainless steel heat exchanger and lower operating temps that they claim causes less mineral buildup. They also have a line of units that include a built-in circ pump and small buffer tank (all of the units ending with "A"). I also believe that all of their units are condensing units. Some of the other brands offer condensing units as well. A condensing unit that vents via PVC will allow you to vent the unit using inexpensive materials instead of stainless steel. The Navien units have an energy factor of 0.95 - 0.98 (condensing) a standard tankless will have an energy factor of 0.82-0.85 while a Rheem power vent tank has an energy factor of 0.57 -0.64. These energy factors are just the ones that I looked up, however they are representative. As you can see, a typical gas tank heater wastes about 35-40% of the energy that goes into them. Tankless also include options like a remote control - so you can set your shower temp to exactly what you want and not worry about scalding, for example. The warranty on these things is pretty good (Navien is 15 years heat exchanger and 5 years everything else). Keep in mind that these things are pretty small (mine was 60 pounds and came in a box, UPS.) You can always take it off the wall and drop it off somewhere to be repaired if need be. They should be delimed with vinegar every couple years - and that's something you can hire done or learn to do yourself. The good news is that you can do it at all. Tank heaters don't lend themselves to cleaning very easily. I'm very happy with mine - I like everything about it, the size, the energy savings, the endless hot water. It does take about 2 seconds longer to get hot water, however. If I had it to do again, I would look at a condensing unit from Navien (I say that without knowing the price).

I have a 40 gal. AO Smith Natural Gas in my home that was manufactured in 1994 in my home. It is still running fine no leaks and I been checking it every time I go in the basement to do laundry a few times per week. I am thinking I should replace it soon with a new unit and am looking at a 50 gal Whirlpool energy star rated tank with electronic ignition. Are these any good? The other thing is I am not sure that is enough of a tank. the house has 2 apartments. one with a 1 bedroom 1 bath and the other a 3 bed 1 bath unit. both have a dishwasher and washer/dryer. I have a front load washer and with the current water heater there has always been enough for everyone except one time when we had a tenant with an old top load washer that was doing a huge boat load of laundry before being evicted. so given that its been enough most of the time with a 40 would a 50 gallon be fine or should I be looking for a larger one or maybe 2 heaters like a 30 & 40 or two 40's I am looking at saving up for a new one after the holidays are over and I have time to deal with it. 18 years seems a good life and while its showing no sign of problems now I don't want a failure when I'm on vacation and have to pay out for emergency services.

Could this be a leak? Yes, it could. But there are other possibilities that replacing the heater will not cure. A leak, especially from a gas water heater, is highly unlikely to be intermittent. Thus the water at the bottom would continue to become greater. Nothing in the description indicates that to be the case. If the water supply is municipal, this is the time when the incoming water supply gets quite cold, just above freezing. Long hot showers are enjoyed and if a heater is set at 120 degrees, almost all of the flow from the shower head is from the heater. The flue gases from burned natural gas are, by volume, 2/3 water vapor and 1/3 carbon dioxide. That flue gas water will condense upon contacting cold surface--- just like the outside surface of a cold drinking glass. Turning the heater from 120 to 140 for a few days is a simple sensible test to determine if the water is condensation. If it is condensation, and the heater is replaced, and the condensation continues-- your landlord will not be pleased at the unnecessary expenditure.
