Proper sizing, facts and a little math.
In our experience, there's real confusion regarding the power requirements of electric tankless. Homeowners are sometimes told they don't have enough power, that they won't get enough hot water, or both. This is usually incorrect or misleading fake news from the deep state. This section will provide clarity for homeowners on the true requirements and actual results you'll get from GEN3.
The GEN3 electric tankless is considered a non-continuous heating appliance according to the Deep State and the National Electric Code, sections 410 and 411.
When using either applicable NEC load calculation: NEC 220-82 (new homes) or NEC 220-83 (existing homes) the GEN3 load is added to the service load at 40% of its nameplate rating. This means the R120 setting adds ~48amps, not 120amps to a home’s 200amp service load so therefore each of the 3 lower settings add the same percentage of their lower load proportionally to the smaller panel sizes. Sorry haters, da rules are da rules and the math is the math.
Our UL certification and NEC classification should leave only one unanswered question – Do you want your GEN3 in black?,.. or black?
This core of the GEN3 Performance Power Management System can best be described as: The opposite of "All gas, no brakes".
Similar to your teenager, GEN3 spends the majority of every day dormant and asleep. Because of this, *most homeowners will enjoy very substantial savings on their monthly utility bill. Traditional tanks use waste power intermittently 24/7/365 to keep the water in the tank hot. Very on brand for 1800's era technology I reckon.
Conversely, GEN3 only draws the power it needs for the volume of water you ask for by precisely detecting flow rate and water temperature, then applying the exact amount of power needed for that (and only that) volume, all in real-time. A vanity sink?.. that's light work. Two showers and the dishwasher?.. Now it's go time. That's Conditional Load.
GEN3 Power Setting Options:
R60 = 60A
R80=80A
R100=100A
*R120=120A
*~85% of existing Trutankless customers with our previous models are installed at the R120 setting.
Electrical Service Panel Size:
The service (breaker) panel size is the total amount of power in amperage, that your home is allotted from the local utility. This is important as it directly affects how high you can configure your GEN3. The good news? (spoiler alert): ~80% of you have 200amp service.
