I have got planning passed for a 1st floor extension onto my bungalow. It will consist of 150mm timber frame sitting ontop of the existing brick cavity wall. Building reg drawings have been passed, but ive got a couple of questions. Can the 150x50 timber frame sit on the external 100mm...

I plan to run 40m2 UFH and 12 rads. Vaillant recommended low loss header to keep weather compensator, flow temp, happy. Barry, doesnt the boilers internal diverter valve change over, as soon as hot water is called for? It shouldnt need to wait for the external zones valve.

I want to add an UFH circuit to a vaillant 937 combi. Vaillant have told me to use a low loss header in the circuit with a separate pump for the rad circuit. Has anyone had to use one?
