Water heater power consumption monitoring.

calum_wilde | Posted in Mechanicals on March 22, 2018 05:36am

I searched but only found one thread from three years ago. The advice then was to use a standard power meter. While the idea is good, the box and meter would take up a large amount of space and wouldn’t really give much information about when the power is being used. Does anyone know of a reasonably priced option to monitor a single 240v circuit? Thanks

I bought 2 like this one on EBay but have not gotten around to installing them. The price is right if they work.

I've used devices similar to the one Walter linked to, and they work fine. I use one to monitor energy used to charge our Nissan Leaf. It won't help tell the time energy is used, but gives a running total of kW-hrs.

I'm using a similar priced one. I tried posting a link but it was blocked as spam. Search on amazon for bayite power meter
