It's definitely pre-1975. You ought to see the boiler.

That's no way to talk about the wife.

3-way valve called 3 way 'cos water can go one of three ways

Except it isn't. They are currently called 'mid-position valves', but used to be called 'diverter valves' when they were hot-water priority.

I did say that in my first post! but as everyone here likes to call them 3-way I thought I'd join in!

If this were the case wouldn't all radiators be hot not just the bathroom one ?

probably! I did add a disclaimer at the bottom!

You should have an isolation valve somewhere, either manual or electric.

You SHOULD have an anti-gravity loop, but the st plumber couldn't be arsed to do it properly.

Bathroom radiators are normally connected to the hot water circuit rather than the heating circuit from your boiler. This is so that it gets hot all year round for drying towels. It'll get hot whenever your boiler comes on to reheat the hot water cyclinder.

My house in London is plumbed exactly like this. The bathroom radiator has a thermostatic valve which helps, but until we got it investigated we didn't rumble why it was massively hot when the CH was turned off.

Possibly your 3 way valve has gone kaput, especially if you've not noticed it before, probably find it in the airing cupboard.

Looks like this:
