![]() While nothing completely revolutionary, this looks like a nice upgrade to existing tech that not only makes things more reliable, but also hopefully cheaper.
I like the carbon heating element vs the spring style. The idea of wifi controlled temperature is very nice. I also like that it has no flow switch... but I'm wondering how they detect water flow with out one? Thoughts? https://www.kickstarter.com/projects...r?ref=category http://myheatworks.com/

![]() Reading through the details, it says that normal tankless heaters take 30 seconds to get warm, with a graph showing a ramping temperature. Is that your experience with the output of your Stiebel Eltron DHC-E 10? This has been something I've been thinking about a bit lately and has been on the back burner to ask about but seeing this in their 'campaign article' makes me want to know.

![]() Without taking measurements, I'd say it probably does take a little while for it to heat up. It does hold a small amount of water in it, and I'm sure it can't heat that up instantly. I think 30 seconds seems a bit much though. And, the Model1 is very close to the same power output as my DHC-E 10 which is 9.6 kW, the Model1 is 11.5 kW.
I would imagine that the volume of water held in the unit has a large effect on how fast it warms up. I would think the Model1 would heat it faster because it is using the water as the resistor, not a heating element. However, you are still putting 9.6kW or 11.5kW into the water heater. Here are the guts of my DHC-E 10.

![]() The problem with using water as the resistor is impedance will vary depending on the hardness of the water.

![]() I am assuming they've covered their bases. They probably have a current sensor that monitors how much power is going in and it adjust PWM duty cycle accordingly.
