Circulator question

Hi all I currently have an old Peerless boiler installed in 1986, It has gone south I have recieved 3 quotes from 3 different Heating contractors all three agree that the current boiler is oversized and that I only need a boiler with around 75,000 btu output. However my heating system is a gravity conversion, currently there is a bell and gosset series 100 1/12 hp curculator on the return side piping, one contractor said that the circulator should be on the supply side and he is replacing it with a taco 007, the other two say the bell and gosset is the only way to go. can anybody shed light on this?

The Taco 007 will work well on your system. I believe you will save on electricity using the Taco 007 vs. the B&G 100.

I have a Grundfos that is comparable to the Taco 007 on my gravity converted system and it works well.

Taco says the 007 was designed as a direct replacement for that kind of B & G.

Installing a pump on the supply side can provide some additional benefits (see: Pumping Away).
