I'm talking about the radiators throughout your house. Are they big cast iron ones? Or do they have a bunch of thin aluminum fins on them?surfbug said:I have big rads....I think
No, I'm not talking about the boiler itself.surfbug said:they are the pipes where the soot collects, right?
Yes, 20 degrees *minimum* spread.surfbug said:I think it was set at 140-180 but I lowered it to conserve while the house is empty.....
I can raise it back, in fact what I will do is raise the hi limit to 180 while I work on the place during the weekends....
then turn it back down for the week when I am not there, until I get a tenant in there....
you said 180-140 minimum 20 degree spread....but this is 40 degrees///....
You could do whatever you want. But for heating efficiency, the higher the boiler temperature, the higher the heat transfer into your living space. But you'll also have higher standby heat loss.surfbug said:I understand why the lower would be 140.....but why so high on the upper?
to conserve, could I do 160-140?
This is awkward, but...
