Had a Rivelli RV80 fitted a couple of days ago. Have set the thermostat for 18C (64F) thinking it would get a bit higher than that anyway. At the minute the "room temperature" measured by the stove through the external thermocouple is reading 25C (77F)......and the thing is still throwing on pellets and working hard! Tried turning down to a lower set point but doesn't seem to make much difference. The guy who fitted it is coming out next week to take a look but thought I'd see if I could get an opinion on here too. Anyone any ideas? Thanks
