I am looking to see if anyone has ever used a VFD on a wood boiler to control the fan speed based on water temp?
 
Do you have storage in your system?
 
No I don't have storage. The boiler has a lot of load on it . When boiler combustion fan shuts down it only will drift over shut down temp 5 deg..
