Looking for Automatic Variable Speed Circulator Pump (closed circuit)
(OP)
Hello, i am looking (as the subject says) for a automatic variable speed circulator pump.
This pump is for a radiant floor heating boiler system in homes. The boiler feeds multiple manifolds throughout the home, with each manifold controled by its own thermostat.
What i am looking for in this pump:
1. Looking for a pump that speeds up based on either: preasure, or the thermastats connnect to the pump, wich scales to how many are on.
2. Application is for USA, though DC power can be used
Thank you for any help in locating a pump along these lines. Im having a tought time locating one on-line. Hopefully i have been clear enough in what im using it for and looking for =)
Thank you

Good luck, it you get something works well, let me know, my house has in floor hot water system, it's running about 92% efficency.

If they exist and operate as per the temperatures inside the area, what you have to do, to optimize power consumption, is to put a DP transmitter across the supply and return headers and control the pump speed with respect to the DP. A bypass line should take care of safe minimum flow.
