Should I turn my boiler up to the maximum?

Thanks again, Istar, for all your info. I tried turning the knob on the boiler to half way, and the boiler wouldn't sustain a flame, so I guess that was too low and I need to have it higher.

That's just what the instructions called it. It is a simple knob though.

Interesting info in this thread that fully explains why I was right to choose a weather compensating controller. I just checked and right now outside its 7.3oC, inside its 21oC - the boiler flow is currently at 41.2oC, so it should be in condensing mode right now. Sweet.

I've seen many of the Nest style thermostats claim to be weather compensating by accessing "local weather reports". Of course these will be measured perhaps tens of miles away, and won't update frequently - nor will they be tuning the temperature of the boiler flow, that'll still stay fixed to whatever its set on the dial on the front.

Yes, good work. Condensing with weather compensation is the best solution. :money:

You are welcome.

Do you want to post the make and model of your boiler?

The controls sound very simplistic, and remember that if it is not a condensing boiler, there will be no advantage to turning it down.

Domestic controllers are supposed to be simple.


A professional PID three term controller is beyond even the average German householder. And yet, they have a PID controller in the basement, and some of them get itchy fingers and want to adjust it. A guy told me he fiddled with it, and the building was swinging wildly between boiling hot and freezing cold, on a daily basis.

Negative feedback loops and hot cross buns. Love it.

It is a ''SIME Combination Boiler Friendly Format 80 E''. I think I got the word ''combination'' mixed up with ''condensing'' There are only five things on the front of it, a pressure gauge, time clock, rotary switch, CH thermostat, and a DHW thermostat.

It's a non-condensing combi ~80% efficient (band 'D').

No point trying to turn it down low it wont make you any savings. Best to set it around 70c and leave it there.
