Arrived to customers home and same issue as yesterday, boiler takes a long time to heat up due to conversion from oil to gas, customer had turned boiler on a little awhile ago and water temperature was at 100, increased temperature on triple aquastat to 150 and when it got close lowered it down to 120 trying to circulate hot water to boiler pipes began to get hot, house reached temperature, set low side of aquastat to 150 instead of 100 so at least it won’t work as hard to warm up, customer just has to be patient.
