I have just finished the install of my Hardy H2 and wondered if anyone had any suggestions on how to optimize the burn. I currently have a Ranco two stage aquastat with independent control of the damper open / close and fan on / off. In the future I plan adding a PLC (Programmable Logic Controller) to control the fan, the fan speed and the damper independently, and was wondering:
Is natural draft more or less efficient than using the forced draft fan?
With natural draft I get long slow burns with a continuous light smoke plume with a low exhaust stack temperature, versus with the forced draft fan running I get a short, cleaner burns with a much higher stack discharge temperature.
I am currently setup to log data 24x7 on water temp, damper open / closed and fan on / off status and plan on adding a stack exhaust temperature sensor when I can scrounge up an RTD.
Any thoughts?
