I had another topic asking how to get the best use of mu system which uses the eco tec plus valiant boiler and unistor.
A gentleman posted that "If your system is set up correctly then you should have a temperature difference on the flow and return pipes to your boiler of 20ºC, with a flow temperature of about 60ºC, this will keep your boiler in condensing mode for longer and lower your gas bills as a result"
By the pipes in the garage near the cylinder are two grey boxes with something about temperature written on them - are these them? They are both set to Auto and not manual, plus I can not see how I would change the temperature (gueess I would open them up). am I right?
If so, I am not sure I would know which does what? system was inherited, can someone please help?
Thanks
