These have only been used for a short period and are fully working. They have adapters to work with different radiators. One of them has been used with the adapter, the other did not require them and the adapters are still in the box.
These are the quiet model for bedrooms and I used them to stop heating the bedrooms during the day; the timer ensured the bedrooms are heated morning and evening only. I’ve since zoned upstairs so I do not need them.
I have the box and instructions for one.
I only require payment for the postage, which I estimate to be no more than £10.
