I learned more than I anticipated needing to, on my quest for the perfect tankless water heater. The Bosch 800 series was my perfect model.While it is now obvious to me why this model is head and shoulders above anything else, you may need to spend some time learning about tankless water heaters to see why it is so significant.1) Ultra efficient, it has 92% efficiency. Only the top of the line models are this efficient. This means lower yearly costs.2) Powerful: 10 gpm! This puppy can power most houses that have mutiple showers and sinks. It is their highest flow unit. It can also be daisy chained so another unit can be attached.3) 15 year PRO warranty. Instead of the 5 year or 10 year of other models.4) New Technology. This is the only Bosch unit to have the technology to create this efficiency and the cooling benefits.5) Reliable. Even though it is cutting edge, some of its parts are based on the 715 unit that is very reliable.6) Easy repair. Bosch has one of the most extensive list of certified repairmen. Also, unlike other companies, most of the parts can be replaced and are easily available, due to its popularity.8) Low heat. This model has 2 condensers. That is why it is more efficient. The added benefit is that the heat coming out of this is like a hair dryer. Much MUCH cooler than most units.9) PVC pipe can be used. I dont know of ANY other water heater that can be vented with PVC pipe. That means smaller pipes, easier work, and much cheaper. Normally water heaters need galvanized vent or Stainless steel venting which is extremely expensive. It can easily cost $300 or more.10) Concentric Venting (one hole). Because the exhaust is so cool, you can use a Concentric Vent to combine both intake and exhaust from one hole (wall or roof). Without this a water heater need TWO 3 or 4 inch in diameter holes, at least 3 feet from each other. So the extremely hot exaust does not get used in the intake and overheat the unit.NOTE:I am just a consumer. I am not a guy that fixes these, nor do am I associated with a company that sells them. I just wanted a tankless & researched like crazy. Rheem, Takagi, and Rinnai were other companies who make products I considered.6 of 8 people found the following review helpful.the bane of my existenceBy HannahI've never written a review of any product before - good or bad. But I'm compelled to review this product on as many forums as possible as it's become, as I said in the subject heading, the bane of my existence. My husband is all about energy efficiency and insisted on purchasing this Bosch tankless hot water heater even though, after installation, it cost more than 7 times what a normal hot water heater would have cost. We hired a certified licensed professional to install it. What a mistake! The heater "errors out" and stops producing hot water at least 5 times a day. I've gotten to the point where I have to run down to the basement to see if it needs to be reset each time I turn on the hot water. I rarely use the dishwasher anymore as the water turns cold during the cycle without me knowing it and the dishes never get clean. Our plumber keeps recommending we turn the temperature down. It is now down so low that I'm no longer able to enjoy a hot shower or bath, which is quite disconcerting as hot baths used to be my favorite means of relaxation after a long, stressful day. I'm considering turning to alcohol.See all 2 customer reviews...Bosch ProTankless GWH C 800 ES NG Tankless Water Heater, Natural Gas
