High Efficiency Electric Boiler
Product Support

The AT Series Electric Boiler is 100% efficient. No wasted energy. This means no fossil fuel and no chimney.

It is ideal for in-floor heating systems, standard baseboard and radiator heating systems as well as for use as a backup heat source for solar applications.

Cost-efficient solution: low annual maintenance required compared to the costs associated with the maintenance of oil and gas systems.

Advanced Microprocessor Control: Safely and efficiently controls the heating elements by monitoring each relay contact that powers the heating elements.

Advanced Load Managing Controller: This gives you the option to allow your utility provider, electric co-op or building management system to remotely control the boiler, contributing to eliminating or reducing electricity peak demand.
