Thermo 2000 electric boilers provide clean, quiet, and reliable hydronic heat. Many Calgary homes continue to use older or legacy Thermo boilers, creating demand for repair services and professional maintenance. Because electric boilers operate without combustion, they require less maintenance than gas systems, but older units can still experience component wear or require electrical upgrades to maintain efficiency.
Comfort Union specializes in both repairing existing Thermo boilers and installing new units, ensuring homes are heated efficiently through baseboards, radiant floors, or fan coil systems.
