Question 1

I have a 4500 sq foot house with 6 bathrooms & 2 jacuzzi's. What size of tankless water heater do I need?

Accepted Answer

You might want to piggyback two units only one turns on if the 4-5 bathroom usage is adequate, but should you need more, then only will the second one turn on. It's just all going to depend on how many baths or hot water usage is needed. If I had to guess that your family is not taking more than 4 showers simultaneously, then only one 4 bath model would be sufficient. Talk to Takagi, their service was more than helpful. I have the TK-540P-NIH, which handles 3-5 showers at the same time. Its all going to depend on if you have water restrictors inside the shower nozzle. I have run the dishwasher, 3 showers, and laundry all at the same time, and it kept up perfectly. This situation is rare. What is common is 5 of us taking showers back to back. Extremely happy with it. Without rewriting all the above, the accumulative hot water flow is what needs to be measured.

Question 2

What country are they made?

Accepted Answer

The gas flex riser is made in Korea, the water flex risers are made in china but I have no tag on the brass valves as to country of origin. They have performed without any problem.

Question 3

Will this work with “ecosmart 11 electric tankless water heater 13kw at 240 volts”?

Accepted Answer

If the unit has a cold, hot and a 220V line there is a different package for those units without the gas valve.

Question 4

will this work with Bosch?

Accepted Answer

That is a question you are better off taking directly to the manufacturer to get the most accurate answer. I can tell you that I purchased this item and used it in my Rheem tankless water heater installation. I can tell you that all of these fittings are of the highest quality. I was very pleased with them. It is an expensive kit and I didn't need every part included. I could have bought individual pieces cheaper but this kit had everything I needed and I knew it was designed for my intended purpose so it was worth it for me to pay a little more. These particular fittings can cut out several of the plumbing steps included in your installation because the installation instructions tell you what kind of plumbing fixtures to use and how to install them but, looking closer (after I had done all of this extra plumbing work) I saw that these fittings were designed to handle these additional plumbing functions (such as your bypass drain fitting).
