Help with boiler temp setting

SeeMe

My choice in settings says from 25min - 80 max, i am still never sure what these should be set to.If i set it to 60 what temp would that be in centegrade or farenheight, or am i barking up the wrong tree here.

The boiler can be set to between 25 Celsius and 80 Celsius for the circulating water.

Celsius and Centigrade are virtually one and the same.

60 is a common number to set to. Lower may be more economical, but may take longer to warm the rooms and keep rooms warm on extremely cold days. (Depending on radiator sizes etc.,.)

If the boiler heats a domestic hot water tank store (i.e. not a Combi) then 60C is recommended to ensure stored hot water remains Legionella free.

Thanks for the reply, it is a combi boiler, i have set my boiler temp at 60 and set my water temp to 60, does that sound ok.

If you have a combi boiler, then Legionnaire's disease shouldn't be a problem.


If you can get away with a lower temperature, then 55C will make the boiler more efficient. But only you will know if that is hot enough to heat your home.


PS. It will be 60 Celsius/Centigrade. 60 Fahrenheit is barely even warm.

Thanks for that i see, i will try a lower setting and see how it goes but the info you gave makes it easier to understand.

Around 60 C for hot water sounds about right for a combi. For radiators you might want to go a bit hotter but it depends on the size of the house, if you have people who would risk burning themselves on a hotter radiator, how many radiators and how many radiator valves are actually open.

Assuming a condensing boiler you want the return temperature from the radiators to be sufficiently cool so that the boiler condenses, making it as efficient as possible. On mine the manufacturer has an eco mark at 67 degrees C for the rad temperature but even that is only a guide and depends on the individual house. A big house might need a flow hotter while a small house might need a cooler flow so the return still comes in under 55 degrees (the condensing point).

Thanks, not a big house just small semi, will just be using 5 rads, 2 of them quite smallish. All helpful comments and no one to burn themselves ( hopefuly).
