yes, but an UFH controller can be configured for that, if you get the right one,

that is the simpliest way of doing it, contactors etc wont work out any cheaper, simply more labour time and charges.

I have done many but the pump outputs on the UFH panels did not have that facility for 3 heating pumps and Hot water pump, the ones I have used are Heatmiser and Uponor, which make is this Steps, could be very useful for future reference.

Never heard of pump over run requiring a separate rad with no trv.

Horses for courses I suppose, by the time I've read the instructions for the ufh I could have screwed the enclose to the wall for the contractors. Not much wiring left from that point.

Don't need a rad with no TRV

Just fit an automatic bypass valve, preferably some way from the boiler (mine's in the airing cupboard)

thats just generally the easy way.

that would do it Dave,

as long as the overrun pump has somewhere to pump the heat to,

it doesnt matter where, as long as its not pumping against a dead end.
