What’s the best setup for a system that has a heating system with existing radiators but a wet underfloor heating system is being added to a new extension. I will need a 3 channel programmer I assume? The plumber mentioned having it on all the time but just working on/off the independent stat in extension. How is it best to tie the manifold in to existing system.

Please use style selector to select BLUE AND WHITE. If you are not already on it. This notice will go once you're on the correct style.
You could put a programmable thermostat on the new UFH and leave the existing programmer for the rads.
Depends if the customer has a preference for a more 'integrated' or smart approach; ie one control interface for all.
The below link might help - you don't have to use the products mentioned, but all these assume existing system is S-plan.

3C in the link works well for small extensions. .I have a conservatory and two en suite bathrooms using these Danfoss valves, and saves the expense of UFH manifolds, circulation pump, mixer and wiring centre.
On the other hand, 1C is not a good idea at all with screeded UFH. The characteristics of UFH and conventional radiators are completely different - rads are heated when you need them, but UFH has a 24 hour lag.
