The optimum central heating water setting for glow worm 30cxi?

kuepper

It's controlled by a dial the minimum setting for which is '1' (which the manual doesn't give a temperature value to ) and the maximum setting is a symbol that looks something like 'IIIII' which the manual says is 82 degrees. There are no inbetween values or symbols. There is no recommendation or suggestions in the manual re where the dial should be set for optimum / best for max efficiency. I found a link to an energy saving trust video but it was no help at all , any ideas?

This subject has been discussed several times on MSE and it seems the conclusion is that there is not a 'one size fits all' answer.


Obviously you want to keep the boiler in condensing mode as much as possible; and that is achieved by keeping the return water flow low.


How do you achieve that with your installation??? - good question!

Nothing comrs 'obviously' to me, I don't even understand those statements. Just thought there must be someone out there with the same boiler whose expereience I could call on
