Let’s Talk About Thermolec B-12U FFB-H Ffb Model Electric Boiler With Modulation Outdoor Reset And Dual Fuel Control Switch 11.5 Kw / 39 328 Btu/Hour
The Thermolec B-12U FFB-H Ffb Model Electric Boiler With Modulation Outdoor Reset And Dual Fuel Control Switch 11.5 Kw / 39 328 Btu/Hour is not your grandpappy’s clunky old boiler. This modern electric boiler from Thermolec boasts full modulation, outdoor reset controls, and dual fuel capabilities, promising efficient and comfortable heating for homes up to 40kW.
My aging propane furnace finally sputtered its last breath during the coldest week of the year. Desperate for a solution that offered both cost savings and environmental responsibility, I began researching electric boilers with dual-fuel options.
The Thermolec arrived securely packaged. My first impression was of its compact size; it was considerably smaller than I expected, given its capabilities.
I was particularly drawn to its dual fuel control switch, allowing for seamless switching between electric and gas/oil based on utility load management signals. This feature promised to save money during peak electric rates, a significant concern given rising energy costs. I had considered another brand, but they lacked the dual fuel capability, making the Thermolec the obvious choice. My initial excitement was tempered with a healthy dose of skepticism; electric boilers have a reputation for being expensive to operate, but the Thermolec’s features suggested a potential game-changer.
