Introducing GEN3

Take a look under the hood of our latest residential unit – showcasing key features, performance capabilities and the build quality our customers have come to expect from Trutankless®

Premium Elements

Made exclusively for Trutankless using Incoloy 800 – a premium alloy with superior resistance to corrosion and hard water decay. Even under extreme conditions, they have elite heat surface transfer and watt density performance. To cap it off (literally), we've designed custom bulkheads for easy replacement.

Heat Exchanger

Our new stainless steel manifold is THE major upgrade in our latest model. Passivated for corrosion resistance and seamless for increased durability. On top of that, the fluid thermal properties deliver higher efficiency with lower internal temperature decay. That's what's up.

Flow Meter

Elite low-flow performance is the big story here. That means improved time-to-temperature across the board. Our new internal layout and location also makes service or replacement simple. Traditional fittings replace the sharkbites – to the applause of plumbers everywhere.

Improved Firmware

GEN3 reaches your set temperature point in ~15 seconds, which is 2X faster than previous models. Light, efficient firmware leverages flow meter tolerances for maximum performance – a reactive control loop capable of regulating 4 separate power settings. More on that below...

But wait, there's more!

If we packed any more stuff into that interactive tour, your phone would probably be on fire right now, so here's a list of other noteworthy features in GEN3.

Safety Redundancy

// Temperature relief
// Solid-state relays
// Software monitoring
// Leak detection shut-down failsafe

Recirc-Pump Compatible

Most electric tankless aren't and we're not even sure why. It's not hard. Our elements activate at an impressively low ^>0.25^GPM well within the pump's range.

99 Energy Factor Rating

With confirmed 99% energy efficiency, why haven't we been "Energy Star Certified"? No seriously, we're asking you, we have no idea.¯\_(ツ)_/¯

Q: Which one should I get? A: Yes

The Trutankless signature "all-in-one-size-fits-all" platform returns in GEN3. Engineered for flexibility and value with 4 power settings ranging from 60-120amps. There's a lot to cover so let's get into it.

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.

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.

NEC Compliance // Classification

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?

Conditional Load // What is it?

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.

*If GEN3 is installed with a recirculating pump, energy savings are unlikely. We advise an attached timer set to your typical hot water use routine.

The Family Home

GEN3 at the R120 setting can provide hot water to multiple fixtures at a time consistent with common daily use, which we consider a "whole-home solution". Example: A standard shower, faucet and dishwasher running simultaneously.

Big Ballers

What about really large homes, like the size you imagine your boss has? That's easy – GEN3 is capable of multi-unit installs giving you the ability to run them in parallel, doubling your output capacity, or zoned where each serves only their section of the home.

Smaller Spaces

Last but not least (well actually I guess kinda least) – For dwellings with lower amperage electrical service, the R60 GEN3 will keep your shower hot. Ideal for casitas, small condos and single occupant dwellings.

We covered power, but how much hot water is that?

Ultimately that's all that matters and this section will cover it all.

When you hear about tankless, you hear the phrase “endless hot water” thrown around a lot,.. and it really is true but just like all things in life there’s a catch, or more accurately,.. differences when compared to what you're accustomed to. Here we'll share what these differences are as well as the proven specs on GEN3 output. We stand behind it all 100% because we believe our customers should know what these differences are up front. We also do this because you'll never see informed customers review bomb your social media.

..and that brings us to:

The Soft Ceiling

The "soft-ceiling" is what we call the limit, or maximum output capacity of your GEN3 unit and all tankless water heaters have one. This is measured in GPM (gallons per minute) and is determined by two variables:

1. Power Setting

This is the setting your unit was installed at, covered extensively in the previous section. This variable is static, never changing.
‍
Example:
R120 = 120A//29kW

Higher power setting = higher ceiling.

2. Temperature Rise

This is the gap between the temperature of your incoming water and the set-temp on your unit. This variable is fluid (literally and figuratively) and is based on region and season.

Example:
[120˚ Set-Temp] - [70˚ In-Temp] = 50˚ Rise

Lower rise = higher ceiling.

The good news: It's not a big deal.

You might exceed this ceiling occasionally, but we call it "soft" for a reason – you likely won't even notice.

Typical Example:

Your GEN3 can provide 5GPM under current variable conditions but you are asking for 5.5GPM – The output temperature will only drop below the set-temperature by a degree or three, barely noticeable to the touch. Still hot.

Extreme Example:

Your GEN3 can provide 5GPM under current variable conditions but you are asking for 7.5GPM – The output temperature will drop significantly below the set-temperature to a temperature more resembling warm, not hot. Obviously, try to avoid doing this.

So that's it really. The operational difference between tankless and traditional tank heaters. GEN3 will never run out of hot water – the endless hot water you long for, so long as your usage is mindful of the "soft-ceiling".

As you've probably experienced firsthand, this same high volume output affects traditional tank heaters too – when they run out of hot water entirely,.. rough scene.
