Boiler output setting, want rads cooler than water
I have an Ideal H12 direct boiler, megaflow cylinder and radiators, S plan system.
My megaflow is set for 60C for legionaire protection, to achieve that my boiler needs to be set above that.(maybe 75?) Problem is that I don't want my radiators so hot for child safety etc..... at the moment I have timer set to alternate between C/H and HW, and I manually turn down boiler output for C/H cycle then up again for HW. Obviously at the hot water setting of 75 I am loosing condensing advantage too. Is there a way to set boiler to do this itself - or any other alternative?
Thanks

This cannot be answered with a short answer
You need to see about legionaries settings and programmes and you can lower both temperatures which will save you on the gas

Leave the temperature at 70-75 on the boiler and install thermostatic radiator valves on the radiators , that way you can control the radiator temperatures
