In sympathy with peoples abroad who might be chilling these next few months and in consideration of rising energy costs closer to home I am implementing a new routine with hopes for conserving.
The first step is to adopt a “time of use” billing strategy that utility companies offer. The utility solicits a pricing incentive for customers to refrain from and reduce consumption during the part of day that is historically prime time for energy usage. My humble abode is equipped with a heat pump and that is a big consumer so I give you the following strategy:
On-peak is from 6 a.m. to 9 a.m., Monday through Friday excluding holidays, so I don’t intend to use the heat pump(s) or worse — system AUX heating, a big draw item. So to comply, the thermostat will be turned down for this time slot. To mitigate rise and shine shivering or breakfast hour discomfort the living space will be pre-heated using the Off-peak ($0.067) rate before it cuts off. On-peak is a penalizing $0.39 per kilowatt hour and to be avoided.
thermostat – settings
- 0500-0600 74 degrees (pre-heating)
- 0600-0900 65 degrees (On-peak)
- 0900-1600 68 degrees
- 1600-2145 72 degrees
- 2145-0500 65 degrees
A Smart Thermostat simplifies the task of micromanaging the setting adjustments.
extra credit
Ensuring that the water heater, also electric, will never draw current during the On-peak is a bit more involved but easily controlled. A relay to open/close the 240v contactors for the heating element can be actuated by a 120v smart plug. An [smart-hub] automation routine then will pause the appliance like a timer.
future plan
There is a Super Off-peak between the odd hours of 10 at night and 5 in the morning. At a mere $0.043 cents per kWh this will be an opportune time period to charge the EV.
maybe…
At some point go off grid? Solar array? Powerwall? In any event, please stay warm.
