Hi

I measured energy usage by anova v2 (900 w) and I see a Max consumption of about 450 watts when heating up water (before it reaches final temperature).

I measured consumption using two methods:

1. TPLink hs110 has energy monitoring and I can see real time power usage
2. Measuring time required to heat up 10lt of water by 5 degrees using 450w and 900w. (See [http://processheatingservices.com/water-heating-time-calculator/](http://processheatingservices.com/water-heating-time-calculator/)) Time required matches my measurements when heating element provides 450w.

I’m on 120V.

Is my unit defective or is other people seeing the same thing?

Hey @Cosoriog this doesn’t sound right to me, but please reach out to our tech support at [support@anovaculinary.com](mailto:support@anovaculinary.com) and they’ll dig deeper into what going on with your cooker’s energy usage.

Anova sent a replacement unit and it uses about 900w when warming up water.

Support representative was quick to resolve issue!

Thanks
