Justed got a Harman III.
Want to use the 21T hot water coil. http://www.hilkoil.com/product.htm
Have a 200btu oil boiler with 80gal phase III indirect water heater, three zones and six people in Conn..
I'm gonna pipe the water to the boiler with a three speed cicr.
No btu rating on the 21T coil. Wondering if 1 is too little or 2 is too much.
Also if anyone is running Harman III which size coal they like best.
Many Thxs Sam
