Longer burn times from a MF5000
« on: November 29, 2015, 09:31:07 PM »

From a member stuck in posting limbo:


I am new to this forum and also to my MF5000. I've only had it one year. I am burning ash and locust mostly and have to load every 8 hours or so when temps are in the 20's.
My settings are 175 with a 10 degree differential and the damper at 50%. Any suggestions on what to do to get my loading times up around 12 hours. We are heating about 3000 sq. ft. with pretty good insulation?

The first thought in my mind is in the form of a question.
How much heat loss do you have underground, what line set did you use and how much?

Wondering what your heat load was before you added the outdoor furnace? like gallons of oil or gas used or amount of electric etc. would give a idea of heat demand. But like Slim noted if you are losing heat before it gets to the house it will increase load. A standard MF under heavy load will use wood. An E or C series really makes a difference when put under heavy load.

And lastly, what’s considered good insulation? My cousins house that my grandmother grew up in was considered to be a tight house at the time as she didn’t have snow on her quilt when she woke in the winter. 

Answering shepherd boy’s question should cover that. Drafty windows will also cause it to be much harder to heat compared to calm days.
