Have any of you had any experience with a Pellet Burner conversion? I have a Hoval Multifuel Boiler that I purchased in 1979. I have burned oil in the spring, summer and fall then for the winter I burn chestnut or stove coal. I am look at a PellX or Janfire burner conversion. Both come with the augar for delivery of pellets from a storage bin. I do not have a local delivery for bulk pellets so I will be using bags. I am planning on building a storage unit for about 1,000 to 1,500 pounds of pellets. I have a couple of issues that I am working through. I am waiting for the units to run on 120 V at 60 hz this should be done in the next 4-6 weeks. Most of the units are 230 V 50 hz. I need to increase the port size that the burner goes through into the boiler. My Oil burner is a 4" unit and I need at least 6.25 inches to put the new burner in. Does any one have information or experience with this type of converision?
