I have an older central forced air heat pump which in the south vancouver island environment runs around a CoP of 3.5 in the shoulder seasons and around a CoP of 2 which is still half what I'd pay for electrical resistive heat (or natural gas).
From todays numbers (with temps around 0 to 4 C, 32 to 40 F) the heat pump is cycling on every half hour or so. When it gets colder (eg. -10 C) it cycles every 20 minutes or so. The thermostat is set at 22 C (~ 72 F) and stays within a degree (C) or so.
Over the past 25 yrs it has certainly paid for itself in reduced electrical costs.
