Does thie have to change to the return side and is the reason for problem heating 2nd floor??
Allso the old grundfus is a 26-64 and the taco 007 came with the boiler. Is my 007 to small compared to the grundfus??

The 007 is fine. It sounds like there is air trapped in your second floor radiators. You need to get the air out. Check for bleeders inside the baseboard cabinets. Try looking at where the pipe comes up from and where it goes down to the basement.

Probably the second floor is air bound. Need to bleed air. I don't think this is a pump problem.

Photos might help us.

Photobucket.com is free and is most popular. Then post the link back here. I guess image shack may work.

You should take several pictures at several angles.

But anyway I see zone valves. Turn the second floor t stat up and tell us if the zone valve is opening.

I assume the 1st floor zone valve is working, and the circulator because you have heat to the first floor correct?

Post back the findings of the second floor zone valve function.

zone valve does open when a call is made.
Comparison of both circs. the grundfus seems to be larger. flow chart at 10gpm = 20 ft head and the 007 10 gpm = 7.5 head. The max a 007 is smaller if im reading the charts correctly. This a larg house with 4 zones a 200 plus ft of basboard

Looks like that green valve center top in the pic is off. Is that the zone you are not getting heat to?

Open it.


Let us know.

No, I was at the time of taking pic shuting some zones so to push the circ through one zone at a time. By comparing the old grudfus circ chart ,the taco 0011 look to be a closer match. this house has 200 + basebrd.

You never did say what the PSI was in the boiler?????


OK turn off all zones/ t stats . Make sure they are all closed. Boiler off. All other valves open.

The red handle valve above the zone valve in question needs to be purged.

Hook a hose to that valve and place in a bucket.

Lift the hadle on the fill valve and watch the pressure gauge. When it gets to like 25 psi open the red valve.

Then close it when the pressure goes down. Then let the pressure rise again to 25, then open it. ( DONT GO ABOVE 30 psi or the relief valve can trip)

Do this several times.

Close the fast fill lever ( Boiler feed) And drain some water until about 10 psi. The fill valve shoule fill the boiler itself to around 12-15 psi.

Turn boiler on and try that zone only.

Post back results.

The circ should be fine if your getting heat to all the other zoness.

Taco 007

Hello Cool,
A James Bond pump will do thus:

In series - 300 feet of 3/4 copper containing 200 feet of 3/4 inch baseboard at 170* will flow 4 gallons a minute.

I don't think the pump is the problem.

Mike is giving you great advice.

Peter

Just because the previous pump was more powerful doesn't mean you needed it. The Taco 007 is a popular and widely used pump for home heating applications. If you you still think the pump is the problem, you need to calculate the head (resistance to flow) of all your piping, fittings, and flow control devices.
