 Tankless water heater |

| I'm impressed with the tankless water heater, but must say that if I had know what I know now about the installation I would have thought twice about purchasing it. My old water heater vented with 3" vent. This unit take 5" and above 2000 ft elevation you must vent with 6". I'm just under 4000 ft. So you must install new vent up through the roof. The unit uses more gas, but for a much shorter time, so it must have 3/4 inch gas pipe plumbed to it. All in all quite a bit of work, but I'm sure it will pay for itself in the long run. I did all the labor, if someone had to pay a plumber to install the product it would be a much longer time before it would pay for itself! |
Not so easy to install

Our 1600p lp was installed about a month ago. The price of the installation was way more than the price of the water heater. While I like the heat and how it runs, my wife thinks it is too cold. She will say it does not produce hot water. I in turn have to turn on the cold tap sometimes to be able to get in the shower. Go figure.
It seems to make enough hot water to run everything in the house however we have not tried to both take a hot shower at the same time.
One of my key goals was to reduce the amount of energy used, not just the payback time. In our part of Northern CA, the price of Propane has been going up at about the same rate as the price of a gal of gas. At the current rates and not figuring in an increasing price rate, it looks like a savings of $498 a year. If the rate continues to increase, an even greater savings will be realized.
Our tank water heaters have been having to be replaced about every 5 to 7 years. The tankless looks to last about 12 to 20 years. That makes a real difference in the life cycle costs/savings.
We will see how this works out over time but currently I am pleased and would buy it again.

| I chose this heater because I could use my existing vent. The first one was damaged in shipping but Bosch shipped a new one within a week. I use well water at a ground temperature of 54 deg. fh. The water coming out of the tap is comparable to the 50 gal tank heater I replaced. However, when taking a shower I notice a slight pressure drop when someone else opens a hot water tap. I also notice a slight temperature change as the water pressure changes with the pump cycling off and on. Overall I can put up with these quirks if I can save on propane. I might try narrowing the working range of the pump. If one had a city water supply they wouldn't have this problem however I know the nearest municipal to me use water from a river which is 39 deg. during the winter. I'm also concerned about the maintenance the heater requires but would still install it if I had a choice. |
Not Wonderful

I bought this water heater to replace another one identical to it. The old one started leaking under warranty. I couldn't get Bosch to honor their warranty without a long, ridiculous, and bureaucratic process. I decided it would be easier and faster to purchase a new one. I don't like this water heater, but all my plumbing, venting, and space was designed especially for it. It doesn't seem to save money. The energy guide says this water heater uses approximately $243 of propane per year at $1.23/gallon. Propane is $2.79/gallon here, so $551/year is more like it. It's very difficult to adjust the temperature to a desirable setting. You have to run the water for a long time before it heats up. Factor that in with the cost of the water heater, propane, expensive replacements parts, worthless warranty, and it doesn't seem very efficient at all. If I had the space, I would have saved money and bought a regular water heater. I can't recommend this water heater to anyone who has space for a regular water heater.
*UPDATE* Less than 1 year after installing this new tankless water heater, it was replaced by a regular 40 gallon electric water heater. I had to build a space to put it, but it is much cheaper to operate and maintain than the tankless. The water pressure doesn't fluctuate and it's hot as soon as I turn on the tap. |
Too much maintenance

Don't do what I did. Read the manual BEFORE you purchase. It turns out that the water valve must be re-built every two or three years. If you are not handy, that's expensive. If the set screws are frozen, it's extremely expensive. If I were doing it again, I would look for a tankless that required less maintenance.
On the plus side, I considered a bigger unit, but this does provide all the hot water I need. |
