nice review, tankless water heaters will save almost anybody a lot of money but this beast looks better than most!

Did anyone answer back on which tankless unit would work best with Solar preheated water? I get water out of my solar that is above 160 degrees.

I purchased Schuco solar water heater, and I want to combine it w/a tankless on demand water heater.
Im reading some coments about Takagi and Rinnai.
What is the best unit to combine w/ solar
Thanks

In the UK the Brittony 11T by Chaffoteaux was the best tankless on demand gas water heater,unfortunately they have recently stopped making them. …with balanced flue gas wall heaters proved a low maintenance long term low cost alternative to central heating(if you consider initial cost and the cost of maintaining and replaceing condensing gas boilers.)

I have owned a Takagi TK-3 Model Tankless hot water heater for almost two and a half years. It is the worst thing I had installed in my house because it has already started leaking. Takagi claims they have a five year warranty, but they want me to purchase a new water heater and send them the old one to determine if the defect is under warranty. Now that is NOT Great Customer Service, so I would definitely purchase a different brand or stick with a tank model.

Heath, wonder if you can comment further on Rinnai.

I just got off the phone with the Rinnai tech rep and he said the units modulate on in and out temperature and should work as well as any tankless units. They could have some issues if incoming water is within about 15 degrees of set point but that should not be unique to Rinnai. I would think the Rinnai units, which modulate all the way down to 15K BTU, should be better than many others, though the Takagi T-K3 does go down to 11K.

On the other hand, one installer I asked said the factory rep told them the Rinnai units would not work with solar preheated water.

In the literature I’ve found, the only manufacturer that I’ve seen explicitly assert solar compatability have been a few of the Bosch units.

I’ve got a low pressure well, which is another concern. Bosch recommends 40 lbs minimum for a well. I see various comments about other units getting “squirrely” which I can’t imagine is a good thing. Would sure be nice to see a definitive review of tankless units installed on well pumps with solar.

Karl is incorrect. I sell solar water heating systems everyday and constantly address the tankless issue. Rinnai heaters really don’t work that well with solar. Takagi and Noritz are the way to go.

Efficiency factor of this Japanese device is truly fantastic.
