Boiler Efficiency Improvement & Heat Loss Explained in

Jan 28, 2007 · Hello, I've been told that my HWBB boiler should run between 5 and 15 minutes a couple of times an hour. Mine is consistenly running for 30 - to an hour and sometimes longer depending on outside temperature. I recently discovered that the temp for the hot water itself was set at 150 and have since turned it up to 175.
