Recently I completed a webinar, the trendy name for those online presentations where the audience watches from home and can submit questions in real time.
My webinar was one of three based on ground and water source heat pumps and their relative benefits. Of the hundred or so questions submitted, 99 were very sensible, one was not. Someone asked: “If air source heat pumps remove heat from the air, will this not eventually have an impact on the local climate, if this technology becomes popular?”
Now I am sure we all know that if you install a ground source heat pump incorrectly, it is possible to freeze the ground near the coil, but this is an unlikely scenario with air source.
You may have heard that I have put my money where my mouth is and installed a heat pump at home; yes the air coming off the thing is cold but I am hardly having to shovel snow from outside the back door on a daily basis. I mean the lovely Lizzie wants a dog, but we are not looking for huskies. Where do these people get their information from? Surely no one believes that a dinky heat pump will actually cool the garden down?
If the next-door neighboursget a heat pump too do, will we have a high risk of penguins coming up the Solent and forming a colony in our garden?
Maybe if this ridiculous theory catches on, we can claim that heat pump technology actually counteracts global warming. Give me strength. The serious point is that there are an awful lot of myths, half-truths and flagrant porkies out there at the moment regarding heat pumps. Rest assured I will be doing my bit to wield the sword of truth in the near future.
