Thank you Richard for a concise and accurate description of the fitting of an adapter to a Danfoss radiator valve. I purchased an Eve Thermo - Smart Radiator Valve and, after removing the Danfoss mechanical valve could not see how the Eve-thermo would fit until I found you video. The adapter was included in the Eve-Thermo box and,once recognised, I followed you video and - JOB DONE - thanks a lot - there are other videos but yours I understood immediately.
