Induction Water Heaters: Are They Worth It? | Page 2

I absolutely love this thread. It is one of the clearest demonstration of the complexity of "energy efficiency" discussions on one end, and of how something as trivial as heating water is in fact, a pretty deep and somewhat convoluted thing.
I am one of the few human beings alive having visited multiple electric water heater factories (these guys don't joke around their industrial secrets!) I have been amazed at how complex and counterintuitive heating water can be.
In strictly electric heating, there's no doubt that resistive wins, if for no other reason that there's little else to measure it against and for most of the reasons listed below. In no way does this mean it's the best or the most efficient, but merely that "it's the best we have for the money".
The conductive heat loss is not insignificant and (for most north-american models) hovers around 90W h. So efficiency should also relate to conservation. Or storage. Whatever energy buzzword you want to tack on there.

Efficiency also means having a durable, reliable equipment. And truth be told, the vast majority of EWH elements have grown to be absolute garbage over the past decade, leading to a record number of failures. These are generally not noticed in 2-elements tanks, or at least, not as much.

It's also helpful to know that US-made and Canadian-made EWH are not the same: they do not answer to the same efficiency standards and while they look similar there are key differences in their designs, not the least of which the number of elements and the temperature set point.

Finally, take other means "more efficient" means with a grain of salt: heat-pump EWH are incredibly efficient. They are also the worse possible idea in nothern climates... Geography counts a lot for "efficiency" and one needs to consider that the current resistive type might not be perfect, but it is the sum of all compromises and currently the one that serves us the best. Can we do better ? I sure hope we can :)

As for the OP's question, well, there are people (yours trully being one of 'em) working on induction-based water heating, not out of efficiency concerns, but out of public health concerns. Legionnaire's disease is far more rampant in EWH than most like to admit, and for areas where only electric is an option that are unfortunate to have that particular bacteria in abundance, there needs to be cheaper, more efficient solutions. That's part of what we're working on.

Magnetic induction instant water heater are popular choice for hoseholds/hotels where gas is not available.

They are an efficient choice for hot water, a great benefit of having an induction tankless instant water heater to hot water for shower is that it doesn&#;t release any gases into the atmosphere.

The technology behind induction heater has developed into a competitive and advanced industry, due to how quiet the induction instant water heater are and how they are typically easier to maintain and install than gas boilers.
