Last month, I consumed an average of 19 kWh per day. Description In warm climates the ECO 8 can provide hot water for one shower and a sink simultaneously. HVAC FORMULAS TON OF REFRIGERATION - The amount of heat required to melt a ton (2000 lbs. 4 Btu per minute times 60 minutes 4884 Btu per hour Convert to watts divide by 3. 2 kWh by your utility company’s electricity rate to determine how much the unit costs per day, and multiply that by 30 to determine (roughly) how much it costs per month.
