water discharging for overflow

I have a Viessmann Atola EC-115 that is discharging about 2 pails of water a day through the overflow pipe (live in Toronto Canada). Is there anything I can do or do I call a pro?

    I presume by overflow you are referring to the pressure/temperature relief valve? Because, unless you live in a tall building, the pressure showing on your gauge seems high. So... check the expansion tank for correct charge, or functioning at all, and if there is an automatic refill, check that.
