I have had sense installed for about 6 months. The device has detected many loads, but not my ecosmart 27kw hot water heater. This is the single largest user by both power and energy in the house. Really wish I could quantity how much a shower or bath costs.
Does anyone else have experience with an ecosmart hot water heater and sense?
Looking at one second data,I can see how it is a tough load to detect. Depending on flow rate and incoming water temp the load is anywhere between 2 kw and 20+ kw.
Looking at millisecond data, it should be pretty easy to identify. The heater has three 9 kw heaters and in any half wave cycle each one is either on the entire cycle or off the entire cycle. They are almost never continuously on, my water inlet just isn’t cold enough here in Southern Arizona. The peak load I have seen is about 22 kW. The heater essentially uses a form of pwm to regulate water temp, just the minimum on time is 1/120 of a second.
