Well last night it got dow. To 14 and my thermostat was set at 72. It was 68 in my house which I didnt think was bad at all. Now tonight its up near 30 and the thermostat is set at 76 and its 70 in the house. I dont get it. Why is there a 2 degree difference when its warmer outside? Now I have a 3speed pump running my first floor. I have a taco 007 running the upstairs which I know is way to small but it was there when I bought the place. But the upstairs is only a 2 degree difference no matter what? Im lost and getting pissed. I just installed new insulated pipe so I dont loose heat. Is this maybe a sign of the pumps going?

What size pump is on your owb? Your 007 pump on your oil boiler should be fine..my buddy had the same problem as you... He put a 011 pump on his owb..Solved the problem

Did this just start happening after replacing the pipe? Did you change the length or size? If you did then the pump is probably too small. If everything is the same as before, you might have an airlock. Is the pump in the house or on the boiler?

[DaveWertz]

Everything is the same as before. The pipe size is same but I may have added 3ft to each side. Would turning the pipe speed up help any? When I blead the system the first floor was a pain. The pump was have problems pushing any kind of air out. I let it sit over night and the air finally did purge itself at the tank when I turned the pumps on. Im sure there was lots of air at the pump after the new pipe install. I just dont see how a taco007 can heat the upstairs better than a wilo 3 speed heating a first floor.

[DaveWertz]

Both pumps are in the house by the way

Ok Dave it sounds to me like you have a ghost flow issue, has this been an issue in the past and did you change the way your piping comes into the oil boiler

[DaveWertz]

Last yr it was the same way. I didnt change anything besides the new piping. Im not sure what the ghost flow is? The house should be within 1 degree of what the thermostat is set at. Last yr when it got down in the single digits I had it set at 72 and it struggled to stay at 65??? Thought it might have been due to uninsulated pipe which im sure some of it was but its still doing the same thing and was only in the teens

[DaveWertz]

Right after the pumps there are flow control valves on each side. Now from the pumps to about 5ft past them it is all 1" copper pipe then turns into 3/4" pipe. Would this affect the flow? What were to happen if I open those flow control valves all the way open?

do you know how many gpm your flow controls are adjustable too?  i have seen some that are to a max of 2 gpm or less??

[DaveWertz]

It doesnt say gpm. Has max temp of 250 and max psi of 125psi.

what psi do you have it at now

[DaveWertz]

Quite honest I dont know. I havent touched it since I moved in. Looks like it hasnt been touched in some time either.

[willieG]

they could very well be dirty if they are old and  restricting flow...i would open them up some (turne each one the same amount so you can put them back where they are now) perhaps by opening them some you can het them to shake loose the debri on them (or you may jsut have topen them a bit and leave them.

they are used to adjust the flow to each of your lines so you get teh proper amount of water to each "appliance" it seems that if they havent been touched in years they could very well be clogged up some and restricting flow?

[DaveWertz]

I will open them up a bit and leave them over night to see what happens

[DaveWertz]

I opened them up. The first floor valve was completley closed. I cound not tighten it anymore than it was. Does these valves still flow water when in the closed position? I opened it up and half a turn to see how that works. Last yr I had problems with air in the lines but I got that squared away this yr. Would it be wise to turn the pump up if I open this valve or just let it on the lowest setting?
