The Lightning electric boiler system is particularly suited to smaller properties where space is limited or where electricity is the only available heat source. Manufactured from Duplex stainless-steel, the cylinders are pre-plumbed with pre-fabricated pipework and wiring. A factory-fitted 3 kW immersion heater provides back-up heat and the option of heating water on different schedules, tariffs and configurations.
