A standard new heater either works or it doesn't, no goofy sensors, no control board, much less maintenance, no muss no fuss. My standard heater was in the kitchen and not in a mechanical closet at that, just sitting there on a back kitchen wall so I had to get it out of there and I went with a Rinnai mounted outside.
I'm very happy with it, installation was cake, but I know even this 5 star unit is a pos compared to a standard heater. In my case it is a neccesairily evil and I do not recomend them to close friends or family.
Get a standard heater, spend wisely. Nevada plumber. When I install a tankless water heater I like to use the Rinnai brand. They work great as long as they are sized and installed properly. That being said I've found for most situations a standard tank water heater is a better choice. I like installing Noritz EZ series tankless. I always warn customers of minimum flow rate, maintenance, and that if one goes bad we don't fix them.
Close customers and friends I always discourage their installation. See what I do not care about tankless water heaters is the minimum flow rate, as well as most home owners and installers are willing to install the cheapest unit and expect to only run one or two faucets at one time. Navien is made in South Korea and fairly new to the US. It has a better presence in Canada.
The Navien units have some nice features, like a built in small tank that lets you obtain low flows of hot water. That little tank acts like buffer and has a built in circulating pump for the tank. You might be able to save almost a dollar a month in energy costs over the others, and if that is significant to you then so be it. Navien, Noritz, Rinnai and Takagi are technically very much the same.
They all deliver about the same amount of hot water using the same amount of gas or electricity. Our thermostatic shower valve this time of year when incoming water temp is at peak can cut back flow enough that the burner on the Noritz turns off.
We set our heater at F to mitigate this showers are still plenty hot. Hasn't happened this summer except when I tried to take a lukewarm shower to cool off after exercising.
We'll see how we do in August. Oh, and make sure you get the flushing valve kit so that you can periodically clean the heater by running vinegar through it.
Soft water here, but lots of FL water is from wells and has higher hardness. Thanks for all of your responses and info. We were told the other day it will take 2 to 3 months for TECO to convert us to natural gas, so I have more time to research the tankless units. The Takagi, Rinnai, and Noritz seem to all be good units if installed properly. I have been reading all the other posts and if we did not need to save space on the ground floor, would just go with a new efficient gas tanked unit.
In Orlando, the incoming water temperature may be pretty warm. Pay attention to the minimum gallons per minute of water flow required to turn the burner on.
The Bosch can be problematic because its flow switch is set at 0. When the incoming cold water is 80 F you may have issues maintaining a warm shower unless you set the tankless water heater down to F, to maintain the minimum flow of water through the unit to keep the burner running.
Other models have flow switches set to activate the burner at 0. These will be much better for your application. We used to have a Rinnai water heater and in the 4th year needed a new heat exchanger which was under the warranty period.
We were denied the warranty because of "bad" water from the city water system. We switched to Noritz and have had no problems going on 6 years! Endless hot water and saved a ton of money on our gas bill. Indem Sie weiterhin auf der Website surfen bzw. Mehr erfahren. Ultimate Lighting Sale. Bathroom Vanity Sale.
