Thanks for posting, interesting.
The video below is by a young chap who has recently installed an air to air system. Towards the end of the video, he gives a very fair review of heat pump costs. His conclusion it that heat pumps will not necessarily save you money compared to a gas boiler system. The main reason to install a heat pump is to reduce CO2 emissions. This is one of the fairest and most sensible videos I've seen on heat pump effectiveness, I wish there was more objective stuff like this on the subject.
