Key points:

* Uses new solid state microwave generator that is more efficient than magnetron used in microwave ovens

* Claimed 84% efficient, with 12% waste heat recycling = total efficiency of 96%

* Drop-in replacement for gas boiler, possibly only some electrical work needed

* Still requires tank as it does not do instant boiling

* UK is phasing out gas powered water heaters in new homes by 2025

* Electrical heaters currently cost more to operate than gas

* Product is currently being prototyped with trials in EOY 2022 and launch 2024

Upvoted to see if anyone here might know how this possibly could be any improvement over plain resistance heating, which has an efficiency of 100%.

Came here to ask exactly the same question. If there is any benefit over a straight resistance heater, it can't be discerned from that article.

Their picture of "emissions" is also dubious/amusing. If it's from natural gas, what you see in that photo is basically steam.

CO2 is invisible.

The smell of snake oil is pretty strong with this.
