I guess it also reduces the chance of a frozen pipe bursting in the loft - it'll be too warm up there for that!

All the pipes in the loft are lagged. But I can sense the scarasm there :-)
please take care with solid fuel systems
I work for Resideo, posts are personal and my own views.
Yep the system convects without power and has anti boil thermostats that open all valves and bring the c/h pump on if power is on. There is also a locked open radiator on the solid fuel circuit and 3 c/h circuit radiators are also locked open in ensuites. The solid fuel boiler also has its own water thermostat that shuts the air feed off. If after all that it does boil ther is a large open vent steel tank on the system.
The problem is making the logic on the Evohome drive the system.
I've been racking my brain on this for you, but the control logic won't work 100% with evohome vs how the Dunsley diagram is wired using a two channel programmer. I haven't given up yet, but think this will need 'wires' to some points of the application that would normally be done wirelessly in a standard system.
I have worked out a circuit that works for the moment. It still requires a manual switch for turning the c/h pump off in summer. I think I can probably eliminate it with a further BDR91 set as a c/h valve but I want to get comfortable with the system as it is for now.
Happy to share if anyone is interested.
