Oiler condenser boiler settings

kah22 · 04-05-2015 08:50AM #1

I've just relocated my condenser boiler/burner to a different spot. The control dial inside goes from 1 to 5. I appreciate that for a condenser boiler to work properly it needs to be set at the proper temperature but I don't know what that is, what temperature do these figures represent?

My question is what is the best number to set this dial at? It was set at number 3 but that barely warmed the radiators, I've increased it to No 4 and that's producing pretty much the same heat as before I had it moved but should I move onto No 5 on the assumption that the hotter the water the easier it is to warm second time around

As always many thanks for your advice

Its the other way around, the lower the water temperature, the more efficiently a condenser will work (it likes colder return water)

Set the dial to the minimum radiator temperature you require.

Thanks for the reply. May I ask a supplementary?

My setup is like this. I have individual theromstats on all radiators, there is a thermostat in the back hall, and I can choose whether to have only hot water, only heat or both. My hall thermostat is set to 21

Do I just lower the condenser control knob down from what I have it set at now (4) until I'm satisfied with the heat I'm getting? Somewhere between mark 3 and 4
