I have a Vaillant ecoTec plus 618 boiler and a Heatrae Sadia premier plus PP250B hot water cylinder.
I have central heating radiators and underfloor heating, I want to reduce my boiler flow temperatures to make it more efficient.
I understand hot water cylinders should store water at atleast 60 degrees to prevent legionnaires disease.
The hot water temperature for our cylinder is set on the cylinder itself and not controlled by the boiler.
Everywhere seems to suggest you can't set flow temps on the boiler below 60 degrees if you have a hot water cylinder due to legionaires, but is this still the case if the boiler doesn't control the hot water temperatures?
Our hot water cylinder is set to 65 degrees. Does this mean it requests water at this temperature from the boiler? I'm not really sure how that part works.
Out boiler flow temperature is currently set to 65 degrees, the max flow temperature set in boiler settings is the default 75 degrees.
if I set the boiler flow temperature to say 50 degrees, would this potentially lead to issues with the hot water cylinder even with that set to 65 degrees?
