Almost done.

One of several windowsills in the house onto which the Succulents have been moved. They have come in from the cold greenhouse before the danger of frost arrives.

Many house plants do not like being near hot radiators in the winter. One of the advantages of having a heat pump is that the water in the radiator is at 45C rather than the 75C typical of a gas fired boiler. The plants prefer this.
The radiators are on all the time whereas with gas central heating they are regularly going on and off.
But they
still keep the room constantly at the temperature you have selected which in our case is 19C.
