I agree that heat pumps provide some great energy efficiency opportunities. I disagree that external heat pump units have to be noisy. They can be very quiet (under 50db). This is especially true of the so-called ductless mini-split systems which are extremely popular in Asia and Europe and are starting to catch on in North America. Manufactures include companies such as Mitsubishi, Daikin, Sanyo, Samsung and Fujitsu. They are extremely efficient and can extract more heat from the air than a resistance (aka baseboard) heater can supply for the same amount of electricity down to temperatures around -18C depending on the model. At milder temperatures, efficiencies are usually 2 to 4 times what a baseboard heater will supply. This certainly covers the Lower Mainland and beyond. You can also apply the advantages of heat pumps to your domestic hot water supply by installing heat pump hot water heaters which are now starting to hit the market. They are made by well known companies such as GE and Rheem. Air source heat pumps are an efficient way to both heat and cool your space and DHW if your climate isn't too extreme. For more extreme parts of the country, it's always possible to with a geothermal heat pump which extracts heat from the ground or a nearby source of water. Unfortunately, the costs are considerably higher.
