Hi guys! I live in the upper north east. I have a Weil McClain WGO 3 oil fired hot water boiler, in my newer 1 1/2 stories cape style home. Boiler and home was built and installed in 2000. Ever year it will heat only to 66 when it gets below zero. To get it to 70 degrees, i need to crank the wall thermostat to 85 at 8 am and by 9 pm it will be 70. Then when it's at 70, i need to turn the thermostat back down to 73 or it will get to hot. This is on the main floor which is on one zone. Home is about 35' by 40' with two zones. It has a total of 60 feet of regular 6" high base boards. I have the boiler set to 190 high limit and 170 low limit.

The top 2nd floor works great if i turn it to 73 in minutes it that temp. The top 2nd floor has a bedroom and a walk in closet and a master bathroom.

The 5 technicians that have come over the years can't find anything wrong with the boiler. The heat lost came out OK, btu's are three times the amount it needs to be for my home ( for later expansions) and the heat lost said there are enough registers. The original installer said to set the high limit to 210. If i do this it will run fine, but i don't want to do this anymore. I was told it not good for the boiler.There are two shut off valves in the cellar for each zone, the tech. has bleed the lines three different time over the years. There is no noise like when there's air in the lines. The base boards are under all windows they are 1" off the floors and about 6 inches in height. They each have one 3/4" pipe going in one side and out the other side, to make a one zone loop to the boiler.There are two shut off/spickets for each zone, which are above the two circulator pump, next to the boiler. Thats were we bleed the zones.The two circulator pumps run very quiet.The 50 gallon water maker was added next to the boiler never run out of hot water. Boiler runs at 15 psi and starts at 170 then stops at 190 degrees. It runs for 5 minutes four times per hour. I was thinking off switching them to seem if one is bad, what do you guys think? I was wondering if it would be better to add more wall registers to the interior walls for the main floor. Or cut that one zone in half and make it to zones. The main floor has a kitchen, living room, two bedrooms, mud room and a bath room about 900 sq ft. Could it be bad circular or the wall thermostat???? Help!!
Thanks guys
