While performance and installation standards have improved steadily over the past ten years, there are still plenty of myths and negativity around heat pumps, which need addressing. Myth 1: heat pumps are not suitable for ‘hard-to-heat’ homes. Delivering heat into a house successfully depends entirely on the heat distribution system. And there is very little research into heat pumps effectiveness in older buildings. My experience is that they can work – even without modifications to the heating system. My house is of mostly 150-year-old stone construction, with some timber frame extension done in the mid 80’s. Insulation levels are adequate at best, or non-existent in some parts, other than loft insulation. I have no problems whatsoever in heating my house to my chosen 18 degrees.
