hot water recirc loop
Posted by Steve on January 24, 19100 at 15:50:42:
I am looking for a piping diagram for pumped hot water recirculation in a system (water heater),that runs at 160 degrees to supply a coil for forced air heating and includes a tempering valve to limit domestic temperature to 120 degrees. I have tried many scenarios but always end up with recirc temperatures equalling tank temperature (way too hot!). Any ideas ?
