“If every home in the United States transitioned to this technology, that would shut down 12 of the largest coal-fired power plants in the U.S.,” Heatworks CEO Jerry Callahan told Freethink.

For more than a century, storage tank water heaters have been the most common method of delivering hot water to homes. These tanks use gas or electricity to keep a reservoir of water constantly hot. When you turn the hot handle of a faucet, cold water enters the storage tank, forcing hot water to travel through a plumping system and to your sink, shower, or dishwasher. It’s an effective but somewhat inefficient system.

What if water heating systems eliminated heating elements altogether? That’s the driving idea behind Heatworks, a technology company that developed a smart tankless water heating system called the Model 3. The goal is to provide homes with hot water as quickly and efficiently as possible.

How do you think we can help speed the transition to green technologies?

As Jordon's excellent reply says. The amount of energy transferred to the water is the same, scale may just slow the heat transfer process. Apart from the idea of heat pumps, a simple approach of using an insulated kettle should reduce the heat transfer from the kettle to the surrounding air (ie a thermos, particularly when the air temperature is low (eg. in a cold room).)

what about using microwaves to heat water?

I'm with everyone else, this basically screams of snake oil. It may heat water, but as others mentioned, this process is likely to be causing electrolysis, which is a good way to potentially cause explosions. I like the idea of a more efficient way of heating water, but this doesn't seem like the best choice.

I should also note that a tankless water heater is kinda meh in action. Hot water seems to take longer to get to the sink or shower than our old tank system. It is also far more touchy than the old system. If you don't have a certain amount of water running then the system shuts down and you get cold water. It is far more difficult to get a consistent, comfortable temperature than the old system. Maybe a combination system, or something else would work better?

Honestly, I think that having some heating near where water heating is needed would make more sense. Have smaller electric heaters near junctions for bathrooms, kitchen, and other areas. It feels like there have to be more efficient ways to heat water so that we save electricity and water.

Gas tankless water heaters aren't saving as much as they claim. The btu amount of the burner is much higher than a normal gas water heater. So without specifying electric or gas before making their statements, they're giving some misleading information.

HHO

Brown’s Gas

He’s not heating water – he’s separating the water molecules into Hydrogen and Oxygen gas, which appears as boiling.

False Advertising.

Boys, water electrolysis occurs only with DC, if you use AC it will heat up instead. This tech is legit, not that it is better than heat pumps, but legit.

I am not too sure about running electricity through the water you are supposed to shower in… stuff like this has existed for a long time inside of showerheads in some not so technologically advanced countries and I believe that to be quite a hazard…

Very cool. I'm even more curious of channeling much bigger units instead of small units? Although I'm not exactly sure of steam ideas along with this process for like salt water and stuff certainly interesting though.

Just quick physics intuitive observation on the claims made here.
If the scaling formed on a heating element reduces the heat transfer/efficiency, then where does that supposedly unused energy go?
Does it not get used up by the electric element, and therefore use less electricity?
Does it get deposited as heat outside of the water heater?
Or does the heating element just get hotter than when new/clean, because the transfer is not as fast?
Likely the latter, and no real wasted energy. Whenever you talk about efficiency of electricity to heat you are almost always talking about close 100% conversion efficiency.. Heat is where all unused electricity goes anyway.
So I would challenge the claim that a dirty/scaly heating element is uses less electricity for the same amount of heat transferred to the water.

Its BS even when you skip the obvious near 100% efficiency of resistive heating of water. They only get faster water heating not more efficiency (and at the cost of more current).
Conductivity of water varies depending on its hardness. They will need system to limit current through the water to have power rating and avoid tripping the fuses. So what will they use? Electronic current limiting with 90%+ efficiency (we are talking about multiple kW peaks) ? Varing the the plate distance? Submerging only part of the electrodes? The control system will drive the efficency down.

Electric water heating is cost-prohibitive for the same reason that heating with electricity costs you three times that of natural gas heating. When you draw water from your source it is usually very cold, to reduce your heating costs you simply fill a dummy uninsulated tank (to warm up the water going into your hot water tank). The incoming water is passively warmed before entering your hot water system. Condensation on hot days can be used to generate grey water for gardening or rinsing exterior surfaces by using a solar pump.

Exactly why I went with an "on demand" gas powered heater; cost to upgrade electric was way too much, and only makes sense if you are trying to go off grid.

the first thing said is instantly misleading. 50% heating efficiency lost is inaccurate. Electric water heaters are 100% percent efficient. If there is scaling the element will get hotter but the same amount of heat will go into the water.

This still ignores the fact that 100 companies are responsible for 71% of global emissions … can we please stop putting the blame on consumers and go after where it matters. Not that you shouldn't do your part it's just that your part is just another drop in the bucket.

I recently had a hot water tank go bad and needed it replaced, I asked about tankless heaters and was surprised when the technician was pretty adamant about talking me out of that option. I feel like the people out in the field need to be sold on the tech so that they will start recommending it. People needing to get their hot water working again are not likely to shop around or argue, they will just accept what is being recommended most of the time.
