Unfortunately these systems are inherently inefficient, almost profoundly so. To work, these systems have to heat up every bit of pipe between the […]

Some states, including Massachusetts, Michigan, Oregon and others require ASME certification for any boiler that’s installed pressurized. Other states require ASME only for commercial […]
This is a question sometimes asked by homeowners. The more advanced pellet boilers of today do require a trained professional to set up the equipment and perform the commissioning. A professional will be able to check and adjust settings, check flue gas composition and temperature, and otherwise ensure that everything is installed to code.
