Motorised valve / actuator query

Hi all


We are in a house with no zoned heating, just a handle in the hotpress that can be switched to send water to the radiators or not (in Summer). Is there any easy way of converting this to a motorised system? Ideally, are there any attachments that simply fit over the existing valve that can be used to turn it as needed (on a schedule, etc) or do we need to get a motorised valve installed instead of what is there? And if so, what kind of money (roughly) would one be looking at for this?



Thanks,
D
