Tim Forcey will talk about how heat pumps (air conditioners) can be used for effective space heating, at a much cheaper cost than gas or electric heaters. This is a follow on from his previous talk on hot water heat pumps (here). He’ll discuss a few systems based on his experience as an energy advisor, including the issues when using ducted and unducted systems in the same house, heat pump hydronic systems, radiator systems and reverse cycle air conditioners.
