I am looking for a supplier for a TACO 007-VSSS-5 IFC Setpoint circulator for my in tank heat exchanger installation. The variable speed pump control keeps a setpoint mix (I am setting at 130F for radiant). My local plumbing supply can get it but it is a 4 week lead item. Anyone know of a good supplier who may have it in stock? I have added my digram FYI. Alternatives are welcome.
