With the new control units on the Garn boilers just wondering if it's possible to retain a coal bed day to day or is it necessary to build a fire from scratch every time.

Thanks.
 
Typically (depending on the wood being burned) there will be plenty of coals to rekindle. Remember that the controller shuts down based on a 10 degree differential between water temp and flue gas. Being that the flue gas is measured at the end of the 4th heat exchanger pass, that means there is still a fair amount of heat being generated in the firebox. Have not heard any complaints. I have a couple customers who do not put enough time on their old style controllers and leave half a load of wood unburned in their Garns. I wish I could talk them into the new controller.
 
The controller is part of the Garn. It's not like an accessory you have to buy separately. They changed from a mechanical "timer" control for the combustion fan to an electronic control a couple years ago.
