Looks good and I like the controlability of rooms independently, I currently just shut off any rooms we don't use (on this house we don't even have TRV's!) I will update to wireless ones when they are a bit more compact and the battery life gets better.
My boiler is c20 years old but I'm not going to replace it until it fails, the roi isn't there for me so we still have the boiler and an immersion heater.
