Since tankless units only heat water as it is needed, the first step is to determine the combined flow rate (in gallons per minute) of all fixtures running at peak demand. For example, let’s say you expect to simultaneously run a hot water faucet with a flow rate of 1 gallon per minute and 2 shower heads with flow rates of 2.5 gallons per minute. The flow rate through the tankless water heater would need to be at least 6 gallons per minute.

Flow rate capabilities vary by unit and depend on how much the heater must increase the temperature of your water. So for step 2, you must determine your required temperature rise. To determine temperature rise, subtract your incoming water temperature from your desired output temperature. Incoming water temperature differs by location and changes throughout the year. Going by the lower temperature in your range can help ensure your unit will not be undersized during the coldest parts of the year.

For example, let’s assume that the incoming water temperature is 55 degrees, and, for most uses, you’ll want your water heated to around 110°F. In this example, you’d need an on-demand water heater that produces a temperature rise of 55°F at your required flow.

With these requirements, you should look for a heater capable of providing flow rates of at least 6 gallons per minute at a 55-degree temperature rise. Most manufacturers provide charts that can tell you which heater meets your needs. You can find these charts in the manuals tab on our product pages. According to Takagi, a TK-jr model would not work at our example measurements, but a T-k4 model would.

Other points:
– Gas tankless water heaters are able to produce a larger temperature rise per gpm than electric models.
– Most demand water heaters are rated for a variety of inlet temperatures.
– Faster flow rates or cooler inlet temperatures can sometimes reduce the water temperature at the most distant faucet.

  1. Hi I am researching this product, and I like your information about this product. My goal is to cut my electric bill, it's been a issue for so long. Please post how it changes or any in your electric bill.

  2. 3 40 amp breakers? what? so you have a 3 phase panel then? are you sure it's not a double pole 40 amp breaker and 1 neutral?

  3. Thanks for the Video – I am seriously considering replacing my existing 38 gallon electric hot water tank with a tankless in my vacation cabin. I have no space to go bigger and I have a family of 5 with frequent guests and we always run out of hot water and have to wait between showers never mind having to wait for it to initially heat up as I turn off the water when I leave.

    Everyone I talk to has someone they know that has horror stories on tankless as they frequently break down. I believe they were all natural gas models. Now having it for several years have you had any problems major issues?

    I can go Propane or Electric. I thought I was favoring electric because it's something I can do myself but I am going pay a pro and they all say to go propane because the electric will spin the meter too much. I tend to think the propane install is more involved and is a higher rate than electric. For me all I care about is having hot water for everyone. It's a vacation home so we don't use it daily. And I think I'd hate to be a slave to propane fill-ups and having to vent it (though they said it can go anywhere). I have a 100 gallon propane tank for my fireplace that I can tap into. I only care about convenance and reliability. I have no problem doing maintenance but less is better.

    Any additional learnings / advice would be greatly appreciated.

  4. this thing is runs your light bill out the roof natural gas or propane tankless is the only way to go they sell them cheap for a reason

  5. amazon daily deal is 320 bucks for the 27 at the moment. At that price it's a good experiment. I miss my old Rinnai NG tankless at our old house. Moving sucks.

  6. So why is there a discrepancy between the unit's thermostat and the analog thermostat? Is the product faulty, or is it because the analog thermostat is faulty? And how much did your electric bill go down?

  7. I wanted ask about about your power bill when you post next time , I am thinking about getting a tankless .

  8. Great product ,I have one installed for six months now it's 8/2016 and I love it money savings is even greater than my old tank heater that started to leak like clock work at the 10year old mark and it cost me so much to run ,if had known better years ago to switch to tankless I would have ,but now I know ,it's hands down a great buy for me . Love it.

  9. so this would drain my peak-time battery reserves in no time great moving on to 6 gallon heater for each bathroom

  10. I am a Plumber and I live in Florida.I have read a few comments here and I would like to answer or comment on some of them.1.Mrs. Sheila Meri… would need to hire a plumber to remove the old heater and install the new tankless.You may also need to hire an electrician.The reason for this is depending on which tankless you purchase the breaker and wiring will need to be upgraded to allow the tankless the power it needs to operate properly.The plumber will wire up the tankless but will not upgrade breakers and such.Also….with a 2 bath home,any unit above the 18 you spoke of will be fine to install.You will also see your electric bill drop as well once you made the switch.Hope I helped…..Good luck to you.

  11. I have had the same unit for over two years, no issues. If you are looking to go tankless, and have an electric house this is the way to go. I waited till the original hot water heater NEEDED to be replaced…no brainer! No vent required on an electric unit.
