Adding a separate control zone to existing CH setup

[pbrain]

Hi, I have wondered for sometime now whether there is a relatiely cheap and simple (DIY) solution to achieve the following.

I have a single cetral heating circuit fed by a combi boiler.

I would like to be able to cotrol the heating (ie radiators) in my bathromm independently.

Reason: In the mornings, I have my heating come on for a couple of hours (its a cold house and it takes a while to get up to a comfortable temperature as i do not have the heating on overnight) to warm the house up before I get up. In reality all I need is the bathroom to be heated.

How could I modify my CH so that only the bathroom rads come on in the morning?

I'm assuming I would need a separate circuit controlled my a separate thermostat - what are my options?

Thanks

You would need a motorised valve on the bathroom pipe work and a 2 channel programmer 1 channel for heating & the other for the bathroom
