Two questions: My wood boiler throws off some convective heat. I want to try and capture as much heat as possilbe into my water jacket (indoor boiler). Has anyone used Roxul to wrap their wood boiler or add an additional insulation layer under the metal covering of the boiler to keep more in the jacket?
Secondly, my circulator pumps get quite warm for my radient heat. I wonder if the technology is there to capture the heat from the circulator pump and dump it into the water in the radient lines? Seems like a waste to have it disapate into the air when the radient only needs 90 degree water to heat the house. Any thoughts or brainstorms on how to capture this heat? Paying for electricity, want to squeeze BTU's out of the device if possible.
