Ecobee3 Data

I’m still enjoying this Ecobee thermostat. Now that the weather is warmer, the house is “coasting” a lot more meaning that we don’t run either the furnace or the air conditioner. It’s interesting to watch how the house warms and cools throughout the day based on the outdoor temperature and the sunshine. For example, here is data for a 4 day period. It was very cloudy the first two days and the second two days were sunny and much warmer.

You can also see roughly in the middle of the graph where the indoor temps jump up quickly. That’s when we returned from being gone for a while and turned the thermostat back on. The rest of the time, the HVAC wasn’t running.

The next step is to measure how much power our furnace blower motor and air conditioner use so I can start to get an idea of how much it costs to run them. I’ll have to figure out how to measure the gas usage too.
