NIBE ELK 42 Electric Boiler 42 kW

The NIBE ELK 42 is a heavy-duty, high-capacity electric boiler unit designed to act as a supplementary peak-load heat source in medium to large water-borne climate systems. It is primarily engineered to dock seamlessly alongside commercial-grade heat pumps, providing a reliable and powerful boost of heat during the coldest winter periods.

Operating at a maximum output of 42 kW, the unit utilizes automatic modulating step controls.
