We will be shipping these http://www.shop.wattsclever.com/european-socket-type/47-ea.h... in a couple of weeks. They don't have UL/ETL unfortunately so we won't be selling them in the US. You can get these from amazon http://www.amazon.com/gp/product/B005OH2EUS/ref=oh_details_o... which work alright.

In Australia, central heating/cooling is rare and high-end - in most places cooling matters much more than heating. The most common climate control method by far are split system airconditioners. We are working on a retrofit device specifically for these, though it will work on any IR controlled appliance.
