g. I am not sure how the following info is used to compare the energy costs when different factors are used (KWH/Litres/BTU/COP)
-Electricity price is quoted as 9.9 cent per KWH at peak, 8.1 mid peak and 5.1 off peak. During the Nov-Dec period we consumed a total of 2,746 KWH at a total cost of $415.81 (HST incl.) thereby costing an average of 6.6 cent per KWH.
-The rated C.O.P for the Climate Master GeoThermal Pump is 2.9 for the closed loop system (also stated on the furnace label is a rating of 42,000BTU).
-Propane cost delivered is 79 cent per litre (HST incl.)
